For precision farming the influences of site-specific N application on rice grain yield and quality were investigated in 0.5 ha paddy field from 2001 to 2003. In pre-cultured soil, EC, O.M., total nitrogen, phosphate and potassium content showed high spatial variation, ranging from 11.63 to 52.03% of coefficient of variation, while that of pH was relatively low. In rice growth characteristics, tiller number at panicle formation stage was more than 10% in coefficient of variation, but plant height, SPAD figure at panicle formation stage and milled rice yield, protein content in brown rice showed less below 10%. Spatial dependence was over 0.60 in pH, total nitrogen, phosphate and potassium in pre-cultured soil and was over 0.50 in plant height, SPAD figure and protein content, while it was below 0.22 in tiller number at panicle formation. The range of spatial dependence was longer than 20m in all factors except for protein content in brown rice. Basal dressing nitrogen rate was positively correlated with PH,
, plant height and SPAD figure. Nitrogen fertilization rate at panicle formation stage was positively correlated with EC and O.M.. Protein content in brown rice was positively correlated with
in pre-cultured soil. Milled rice yield was positively correlated with plant height, tiller number and SPAD figure at panicle formation stage.

This experiment was carried out to investigate the optimum planting density in low fertilizing cultivation of machine transplanting in rice field of Honam Agricultural Research Institute, NICS for
. Sobibyeo which belongs to medium maturing variety and Nampyeongbyeo which belongs to medium-late maturing variety were transplanted on May 30. In this experiment, there was no significant difference in heading date between planting density and nitrogen fertilization rate, and heading dates were August 8 in Sobibyeo, and August 14 in Nampyeongbyeo respectively. In relation to lodging character, lodging Index was high where the nitrogen fertilization rate and planting density were high. As planting density increases, panicle number per
increased irrespective of nitrogen fertilization rate. When nitrogen was 6 kg/10a, rice yield of Sobibyeo was more where planting density was 90 hill per
, and that of Nampyeongbyeo was more where planting density was 80 hill per
. When nitrogen was 9 kg/10a, rice yield of Sobibyeo was more where planting density was 100 hill per
, and that of Nampyeongbyeo was more where planting density was 110 hill per
. Head rice rate of brown rice was higher when planting density increased, and was higher at 6 kg/10a nitrogen rate than 9 kg/10a nitrogen rate in all varieties.

The core questions for determining nitrogen topdress rate (Npi) at panicle initiation stage (PIS) are 'how much nitrogen accumulation during the reproductive stage (PNup) is required for the target rice yield or protein content depending on the growth and nitrogen nutrition status at PIS?' and 'how can we diagnose the growth and nitrogen nutrition status easily at real time basis?'. To address these questions, two years experiments from 2001 to 2002 were done under various rates of basal, tillering, and panicle nitrogen fertilizer by employing a rice cultivar, Hwaseongbyeo. The response of grain yield and milled-rice protein content was quantified in relation to RVIgreen (green ratio vegetation index) and SPAD reading measured around PIS as indirect estimators for growth and nitrogen nutrition status, the regression models were formulated to predict PNup based on the growth and nitrogen nutrition status and Npi at PIS. Grain yield showed quadratic response to PNup, RVIgreen around PIS, and SPAD reading around PIS. The regression models to predict grain yield had a high determination coefficient of above 0.95. PNup for the maximum grain yield was estimated to be 9 to 13.5 kgN/10a within the range of RVIgreen around PIS of this experiment. decreasing with increasing RVIgreen and also to be 10 to 11 kgN/10a regardless of SPAD readings around PIS. At these PNup's the protein content of milled rice was estimated to rise above 9% that might degrade eating quality seriously Milled-rice protein content showed curve-linear increase with the increase of PNup, RVIgreen around PIS, and SPAD reading around PIS. The regression models to predict protein content had a high determination coefficient of above 0.91. PNup to control the milled-rice protein content below 7% was estimated as 6 to 8 kgN/10a within the range of RVIgreen and SPAD reading of this experiment, showing much lower values than those for the maximum grain yield. The recovery of the Npi applied at PIS ranged from 53 to 83%, increasing with the increased growth amount while decreasing with the increasing Npi. The natural nitrogen supply from PIS to harvest ranged from 2.5 to 4 kg/10a, showing quadratic relationship with the shoot dry weight or shoot nitrogen content at PIS. The regression models to estimate PNup was formulated using Npi and anyone of RVIgreen, shoot dry weight, and shoot nitrogen content at PIS as predictor variables. These models showed good fitness with determination coefficients of 0.86 to 0.95 The prescription method based on the above models predicting grain yield, protein content and PNup and its constraints were discussed.

In the preliminary experiment, the factors(soil moisture content, type of organic fertilizers, wound of ginseng, and concentration of rusty-root causing bacteria) inducing the rusty-root of ginseng were investigated. The Hue values were measured for the degree of rustiness affected by the factors. The rustiness was severe on the wounded-ginseng and on the ginseng inoculated with Agrobacterium tumefaciens (CG20126). The Hue values of the control, the non-wounded ginseng inoculated with CG20126, the wounded-ginseng, and the wounded-ginseng inoculated with CG20126 were 113.3, 108.1, 85.8, and 57.5, respectively. The Hue value of the horticulture bed-soil was 56.8 whereas the value of the paddy bed-soil counterpart was 64.7. The Hue values on the ginseng roots grown in the soil containing 10%, 20%, 50%, and 70% of moisture, were 96.2, 85.9, 78.0, and 75.7, respectively. The organic fertilizer increased the rustiness of ginseng and the range of Hue values was 35.2-27.8. The increased concentrations of A. tumefaciens CG20126 increased the rustiness of ginseng. The concentration of A. tumefaciens CG20126 at
resulted in the Hue values of 62.8, 63.3, 55.6, and 48.8, respectively.

This study was conducted to investigate the effect of onion cultivation under paddy and upland condition on the yield and storage of onion bulbs. In comparison of soil conditions, nitrogen, phosphate, potassium content and average temperature in upland condition were higher than those of paddy condition, but calcium, magnesium, sodium and water content in paddy condition were higher than those of upland condition. The growth of aerial part was better in upland cultivated condition. It showed that bulb formation in paddy cultivated condition was faster during in early growth stage, but was slower during in late growth stage. Average bulb size and weight were higher in upland cultivated condition, but dry weight per 100 g fresh weight and bulb hardness were higher in paddy cultivated condition. Sugar contents, inorganic compounds, nitrogen, phosphate and potassium content of onion were higher in upland cultivated condition, but calcium, magnesium and sodium content of onion were higher in paddy cultivated condition. In distribution of onion bulb size, most of large sized onions were produced in upland cultivated condition. Average bulb production for seed harvesting were
higher in paddy cultivated condition than that of upland cultivated condition. The rotted rate of onion was about
in upland cultivated condition respectively, showed favorable result as the difference of
in paddy cultivated condition.

A pot experiment was conducted for two years to evaluate the effects of purified Si fertilization combined with
on the nutrient uptake, plant growth characteristics, and photosynthetic characteristics of rice in water melon cultivated soil. In 2002, plant height was positively affected at 25 DAT (Day After Transplanting) by Si fertilization in 100%N treatment. However, in 2003, plant height at 25 DAT was negatively affected by Si fertilization in low N level but it was reversed in high N level with initial increase of plant height. Tiller number per pot was positively affected by N and Si fertilization level, especially for high N fertilized treatment. Leaf color was positively affected by Si fertilizatlon in no N fertilized pots, however, Si was not effected in 50%N and 100%N fertilized treatments. N harvest index (NHI) increased with increased Si fertilization in no N plots, however it decreased with increasing of N fertilization level. Nitrogen use efficiency (NUE) decreased with increasing of fertilized N but Si fertilization increased NUE in 50%N plots, however, it was not different by the Si fertilization level in 100%N plots. In 50%N+200%Si plots, NUE was greatest with 130 and shoot N content was
. N content (
) in rice plant increased with increasing Si fertilization in no N plots at panicle initiation stage, 50 and 100%N plots at heading stage and all N treatment at harvesting time. This was mostly more efficient in late growth stage than early growth stage. The concentration (%) of P and K increased with increasing N fertilization level at heading and harvesting but it was not significantly different by the Si fertilization treatment except a little decreasing with increasing Si fertilization level at heading. Potassium content was also not significantly related with N fertilization level except increasing with Si fertilization level at panicle initiation stage. Plant Ca content (%) decreased with increasing of Si fertilization at heading stage and Si fertilization increased Ca content at panicle initiation stage and heading stage and it increased with increasing of Si fertilization level. Photosynthetic activity was not directly related with Si fertilization amount, however, Fluorescent factors, Fv'/Fm' and PsII, were positively affected by Si fertilization level. In conclusion, N fertilization in Si 200% fertilized condition should be reduced by about 50% level of recommended N fertilization for rice cropping in green-house water-melon cultivated paddy field. However, improvement of Ps by Si fertilization could not be attributed to Ps activity in the same leaf area but because of increased total leaf area per pot improved fluorescent characteristics.

This experiment was conducted to elucidate the basic physiological phenomena of pollination and fertilization for breeding in perilla (Perilla frutescens) through different 6 varieties derived from 2 genera under 4 temperature conditions at day and night. The pollen germination was observed after 30 minutes and pollen tube reached the lower part of pistil after 1 hour from artificial pollination. Seed formation was affected by temperature condition and a variety. The early maturing variety 'YCPL 25' showed a poor seed formation rate under the night temperature below
, but the late maturing variety 'YCPL263' did not lowered even though the night time temperature was
. The function of pistil was long maintained under the low temperature from the fact that if the live pollen pollinate artificially to the flower that does not form seed under low temperature, fruiting was made. Pollen was created and pollen tube was developed in the time of petal becomes bigger than calyx in five varieties, 'YCPLl77-1' etc. However, pollen was made and pollen tube was made only 71% in a green chajogi 'YCPL205-1'. These physiological phenomena of pollination and fertilization could be applicable to the emasculation and an effective breeding in perilla.

In order to investigate the effects of ethylene on the seed development of three corn types (dent, sweet, and super sweet corns), aminoethoxyvinyl glycine (AVG) and silver thiosulfate (STS) and ethephon (2-chloroethylphosphonic acid, CEPA) were applied either on whole plants or shanks of ears at 9 and 21 days after silking. Ethylene production of developing super sweet corn seeds was much higher than those of sweet and dent corns. The cavity in the endosperm tissues of the super sweet corn started earlier and endosperm was collapsed more severely compared to those of sweet and dent corns. Ethylene production seemed to be related to the death of endosperm cells to form a cavity. Application of AVG and STS reduced ethylene production and delayed cavity formation in endosperm of super sweet corn seeds, while CEPA increased ethylene production and enhanced the time of cavity formation. AVG and STS increased 100-seed weight, while CEPA decreased.

An experiment was conducted to characterize the seed vigour of sweet (su) and super sweet (sh2) corn seeds stored at different temperatures and relative humidities (RH). Hybrid seeds of Early Sunglow
Golden Cross Bantam 70 (su) and Xtrasweet 82
Fortune (sh2) were stored at different temperatures (
) and RH(70 and 85%) for 10 months. Results of the experiment show that seed deterioration of super sweet corn was much faster than that of sweet corn under all storage conditions. Germination rate of sweet corn seeds at
and emergence rate in cold test showed similar patterns. Emergence rate of super sweet corn in cold test was significantly lower than the germination rate at
. Germination rate of both sweet and super sweet corns was positively correlated to the emergence rate in cold test, but the correlation coefficient of super sweet corn was much lower compared to the sweet corn. This implies that the viability of super sweet corn seeds should be tested in the cold test to estimate field emergence rate. Seeds of sweet corn could be stored for 5 months under all storage conditions without significant seed deterioration, while those of super sweet corn should be stored at low temperature and RH. The emergence rate of sweet corn in cold test was not correlated to the leakage of total sugars, electrolytes or
activity, while that of super sweet com was positively correlated to the
activity, negatively correlated to the leakage of electrolytes, and was not correlated to the leakage of total sugars.

This study was carried out to compare the grain quality under lodging time and grade at ripening. Ripened grain ratio and 1000-grain weight were higher with lodging of plants at
angle from the ground and increased with crop development. The number of spikelets, as well as the protein and amylose content of the grains, were higher in plants under severe or complete lodging than those under lodging at
angle from the ground. Palatability and sensory evaluation values were higher in plants under lodging at
angle from the ground than those under complete lodging. Brown rice: rough rice ratio was higher with lodging of plants at
angle from the ground and increased with crop growth. Milling recovery and milled rice recovery were higher with lodging of plants at
angle from the ground, whereas chalky grain, cracked grain and damage grains were higher at complete lodging.

The nitrogen fertilization effect on growth characteristics and isoflavone content was investigated in this study, and isoflavone analyzed by HPLC with photodiode array (PDA) detector and reverse-phase
column. Fertilization levels were no-fertilization, no nitrogen, 50% decreased in nitrogen, standard and 50% increased in nitrogen fertilization. The 50% increased nitrogen fertilization showed the highest growth characteristics then other fertilization level and the number of pod and seed showed maximum value 31.9 and 72.3, respectively, and seed yield was 2,460 kg/ha. During growth stages, isoflavone content in leaf, stem and root of soybean plants decreased to R5 stage then increased to R7 stage. Isoflavone content according to various nitrogen fertilization condition, in case of none fertilization, no nitrogen, 50% decreased nitrogen fertilization showed higher value than those of standard and 50% increased nitrogen fertilization levels. Aglycon content among the isoflavone isomers showed much higher in plant than in seed. The highest isoflavone content was found in the root of soybean plant parts. Isoflavone content of seed was higher in none, no nitrogen, 50% decreased nitrogen than those of standard and 50% increased nitrogen fertilization.

The purpose of this study is to measure fundamental data required for the prediction of rice quality and to develop regression models to predict protein, amylose, moisture and fatty acid contents, and Toyo taste meter value (TTMV) of brown and polished rice from hulled rice NIR spectra. NIR spectra of hulled rice measured in transmittance mode (850-1050 nm) and in reflectance mode (400-2500 nm) were used to predicted chemical compositions of brown rice and polished rice. For most chemicals, the transmittance spectra could provide better calibration results than the reflectance ones. Beside the Toyo taste meter value (TTMV), the hulled rice spectra could predict chemical contents with the determination coefficients higher than 0.8. Spectra of hulled rice measured in transmittance mode could be used for the prediction of chemical compositions in brown rice and polished rice precisely. However, taste value of polished rice was a constituent that was hardly to be predicted.

This study was carried out to evaluate the nutritional properties of quality protein maize (QPM) and to select the elite lines for corn breeding. Two laboratory procedures for simultaneous identification of QPM and lysine content analysis were performed. The
lines of KS5/QPM and KS135/QPM were analyzed with opaque-2(o2) specific SSR marker in order to differentiate the opaque-2 carrying QPM lines from the non-opaque genotypes. Although no significant difference in protein content, significant differences in lipid, ash, and crude fiber contents were observed. The composition of unsaturated fatty acid of QPM lines was slightly lower than non-QPM lines, but there was no significant difference. Sulphur-containing amino acids such as methionine and cystine showed no difference between QPM and non-QPM lines. However, lysine content of QPM lines was 38% higher than that of non-QPM lines, and the essential amino acid content of QPM lines (28.1%) was higher compared to non-QPM lines (27.1%).

The objective of this study was to compare and analyze the acceptability and consumption attitude for soy foods between Korean and Canadian university students as young consumers. This survey was carried out by questionnaire and the subjects were n=516 in Korea and n=502 in Canada. Opinions for soy foods in terms of general knowledge were that soy foods are healthy (86.5% in Korean and 53.4% in Canadian) or neutral (11.6% in Korean and 42.8% in Canadian), dairy foods can be substituted by soy foods (51.9% in Korean and 41.8% in Canadian), and soy foods are not only for vegetarians and milk allergy Patients but also for ordinary People (94.2% in Korean and 87.6% in Canadian). In main sources of information about soy foods, the rate by commercials on TV, radio or magazine was the highest (58.0%) for Korean students and the rate by family or friend was the highest(35.7%) for Canadian students. In consumption attitude, all of Korean students have purchased soy foods but only 55.4% of Canadian students have purchased soy foods, and soymilk was remarkably recognized and consumed then soy beverage and margarine in order. 76.4% of Korean students and 65.1% of Canadian students think soy foods are general and popular and can purchase easily, otherwise, in terms of price, soy foods were expensively recognized as 'more expensive than dairy foods' was 59.1% (Korean) and 54.7% (Canadian), and 'similar to dairy foods' was 36.8% (Korean) and 39.9% (Canadian). Major reasons for the rare consumption were 'I am not interested in soy foods' in Korean students (27.3%) and 'I prefer dairy foods to soy foods' in Canadian students (51.7%). However, consumption of soy foods in both countries are very positive and it will be increased.

Viral diseases, especially Barley yellow mosaic virus (BaYMV) and Barley mud mosaic virus (BaMMV), have been most serious in barley fields. In this study, we investigated the effect of different level of resistance to viral diseases on the plant growth and yield in barley. Various viral disease symptoms on leaves of overwintered plants were similar between medial-resistant and susceptible varieties of Saessalbori and Baegdong. In diagnosis of virus infection, BaYMV and BaMMV were detected in Saessalbori and Baegdong, but not in the resistant variety, Naehanssalbori. Plant height was restrained about
prior to heading in Saessalbori and Baegdong comparing to Naehanssalbori. Even if both varieties were medial resistant to virus diseases, Saessalbori was different from Baegdong in heading date and culm length due to its recovery from viral damages prior to heading. Both medial-resistant and susceptible varieties were quite different from the resistant variety in yield components such as heading date, number of spikes and culm length when evaluated in the virus-infected or non-infected field. Baegdong delayed 7 days in heading date and reduced by more than 50% in culm length and spike numbers as compared to Naehanssalbori. On the other hand, Saessalbori showed similar heading date, but was shorter by 20% in culm length than Naehanssalbori. Three varieties tested in the non-infected field over two years were not significantly different for yield potential with ranges of
. However, significant yield reduction (P<0.01) was observed in Saessalbori and Baegdong with ranges of
as compared to Naehanssalbori (391 kg/10a) when tested in the virus-infected field. Yield potentials of Saessalbori and Baegdong reduced by 35 and 63%, respectively in the virus-infected field as compared to those in the non-infected field. Our results showed that damages from virus diseases were significant on the early plant growth to yield and its components in barley.

In order to breed hemp variety with nondrug type adapted to Korea, a total of 44 accessions were introduced from Center for plant breeding and reproduction research (CPRO) In Netherland and evaluated for plant growth characteristics and contents of cannabinoids such as tetrahydrocannbinol (THC), cannabidiol (CBD), Cannabinol (CBN) in Korean climatical and geographical condition. 1. In Korean geographical position which latitude is
, days to flowering and stem length were shorter than in Netherlands which latitude is
. But THC content was not shown significant difference between two areas. 2. Corrected accessions of hemp were classified into 3 variety groups by cluster analysis and 4 accessions including Korean local variety were not classified into any variety group. 3. Most hemp accessions have low THC contents but were not suitable for fiber production in Korea due to short days to flowering and stem length. 4. Among the introduced accessions, IH3 was suitable for breeding material of fiber hemp with non-drug type because of low THC content and similar days to flowering with Korean local variety.
