Varietal Differences of Major Chemical Components and Fatty Acid Composition in Mungbean
KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 1~6
These experiments were conducted to obtain basic information for breeding material on the utility characteristics in mungbean, The crude protein, fat and ash content were 24.3, 0.67, 3.6％, repectively, and the fat content showed varietal differences, whereas the protein and ash content was not significantly differences among the varieties. The negative correlation existed between protein and carbohydrate content, seed moisture and fat content, seed weight and fat content. The unsaturated fatty acid contain 60∼67％ and there were oleic, linoleic, linolenic and archidonic acid, and the saturated fatty acid contain 33∼40％ and there were stearic, palmitic, behenic and lignoceric acid. The major fatty acids in mungbean were linoleic, linolenic and palmitic acid, and have contained 33.46, 21.87, 21.72, respectively, and oleic, stearic and arachidonic acid contained 5.98, 5.88, 4.87, respectively, and the behenic and lignoceric acid left traces. Highly positive correlation existed between palmitic and linoleic acid, oleic and lignoceric, behenic. However; palmitic and arachidonic, lignoceric acid, oleic and linolenic acid, arachidonic and liniceric acid showed negative correlations with each other. Seed weight of tested varieties showed highly positive correlation with oleic, arachidonic and behenic acid.

KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 14~21
This experiment was conducted to identify the growth and yield differences in rice cultural types: Broadcasting on flooded paddy surface(BF), drilling on flooded paddy surface(DF), puddled-soil drill seeding(PD), drill seeding on dried paddy flat(DD), and machine transplanting of lO-day old seedling(MT) at National Honam Agricultural Experiment Station in 1995. Among the cultural types of direct seeding, the number of seedling stand showed high in order of DD>BF>DF>PD. Tillering at early growth stage was faster in MT and effective tiller showed higher in MT than in direct seeding. Growth duration from seeding to heading was longer in direct seeding than in MT for 2-13 days of Dongjinbyeo and 10-18 days of Nonganbyeo. Root distribution ratio at the surface soil revealed high in order of BF>DF>PD>DD and MT. Culm wall thickness of 4th internode was thicker in machine transplanting of 10-day old seedling than in direct seeding, and the depth of buried culm showed deep by turns of MT> DD>PD>DF and BF. The height of center gravity and moment related to lodging revealed higher in direct seeding than machine transplanting that resulted high lodging index by turns of BF>DF>DD> PD among the direct seeding cultural type. Lodging was occured seriously in the order of BF>DF>PD>DD =MT in Dongjinbyeo but wasn't significantly different in Nonganbyeo among the cultural type. The yield components and grain yield showed varietal differences but was not significantly different between in MT and in direct seeding, and among cultural types of direct seeding.

KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 22~32
This experiment was conducted to obtain information for the cultivation of Korean valerian(Valeriana lauriei var. dasycarpa Hara) which will be useful for medicinal and aromatic resources. The effect of different temperature conditions, light intensities and soil water conditions on growth, yield and component of essential oil of V. fauriei were measured at the Dankook University, Cheonan, and a study on the shading treatment was at Umsung, Chungchongbukdo, and Jinbu, Kangwondo, in 1995. V. laudei was planted at five different temperature conditions, 10, 15, 20, 25 and 3
, eight light intensity conditions, 1, 000, 2, 500, 5, 000, 20, 000, 30, 000, 40, 000, 50, 000 and 60, 000lux, six soil water contents, 30, 45, 55, 70, 80 and 90％ of the saturated soil, during growth stage. Shading treatment was three conditions, 0, 25 and 50％, during the daytime in field conditions. Photosynthesis had a highly significant relationship with temperature conditions in a quadratic regression model, from which the temperature for the plant growth was estimated to be 17.7
. A highly significant quadratic regression was noted between temperature and leaf width or root weight of V. fauriei. It was estimated from the regression equation that the optimum temperature for root growth was 20.3
. The content of essential oil and extract rate of root was the highest in the 15~2
. Photosynthesis also was significantly affected by light intensity in a quadratic regression model, from which the optimum light intensity for the growth was estimated to be 40, 000lux. Root yield was more produced in Jinbu than that of in Umsung. The root yield was increased by the shading treatment in Umsung, whereas it was decreased by the shading treatment in Jinbu. The content of essential oil was not affected by the shading treatment of plants during the cultivation, while the compositions of components of essential oil were related to the growing locations. As soil water content was higher, the growth and content of root extract were increased. The optimum soil moisture for the growth of V. fauriei was 80~90％ of the saturated soil. In summary, the results indicated that the growth, yield and component of essential oil in V. fauriei were affected by environmental factors as well as soil moisture.
Changes of Phytohormones in Rice and Tobacco Protoplasts under Different Cultural Conditions
KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 33~41
This study was carried out to establish simple and easy methods to judge the survival, senescence and death of the protoplasts in culture system by identifying the marker substance related to metabolic status of the cells. When rice and tobacco protoplasts were cultured in MS and KM-8P media containing 2,4-D or coconut milk ABA decreased especially in the media containing coconut milk, but GA
, IAA and zeatin increased as the cultures progressed. The decrease of ABA and increase of zeatin was especially remarkable. When the supraoptimal amount of osmoticum (mannitol) was added to the culture media ABA decreased after a momentary increase, but other growth hormones slowly increased as the concentration of the osmoticum increased. Contents of individual hormones were contrasted when protoplasts rice and tobacco were cultured on the same medium containing 10mM super mine or NaCl. Tobacco protoplasts were more sensitive to NaCl stress and stopped protoplast division at the late stage of culture. Protoplast viability decreased greatly in 48 hours when the protoplast were at 32
on a medium lacking several components. ABA content increased up to 10 days from incubation in negative proportion to the protoplast viability. On the other hand contents of other growth hormones, especially zeatin, decreased. The present results clearly showed that the contents of individual growth hormones in the plant protoplasts in culture varied sensitively in response to environmental factors that they are faced with. This indicates that the physiological states of the protoplast, such as survival, senescence or death can be simply judged based on the quantitative analysis of those hormones by ELISA.
Phytohormones Responses to NaCl Treatment in Rice Seedling
KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 42~48
Ten days old rice seedlings were treated with NaCl and the contents of endogenous hormones such as GA
, ABA, IAA and zeatin were measured by ELISA. Water content and seedling growth were decreased as the salt concentration was increased. GA
increased up to 24 hours after NaCl treatment and decreased thereafter. ABA was raised by four times in 48 hours after NaCl treatment. IAA and zeatin decreased as the NaCl concentration and duration of treatment increased. GA
and ABA showed positive and negative correlation with the water content in the plant tissue, respectively.
Effects of Rice Straw Application on Barley Growth and Grain Yield in Paddy Field
KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 49~55
For the labor-saving cultivation of barley in rice-barley double cropping system in paddy field, a series of expriments on the effect of rice straw application were carried out at the National Yeongnam Agricultural Experiment Station from 1992 to 1993. The affection of phenol compounds released from fresh rice straw could be lessened when seeded under rice straw in the soil and that made emergence rate increase by 11％, compared with that on application on the rice straw. Although utilization of rice straw as an organic material caused the poor growth of barley in early stage, it could be enhanced the culm breaking strength. On this reason, affected by rice straw, grain yield was increased from 8％ in common barley and up to 20％ in malting barley. The more nitrogen, CaO
2 and SiO
applied, the more decomposition of rice straw accelerated from 2％ to 6.9％. On the application of rice straw as an organic material in malting barely cultivation, the content of crude protein was decreased while 1,000-grain-weight and grain assortment was increased.
Damage of Rice, Soybean, Potato, and Red Pepper as Affected by Simulated Acid Rain
KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 56~60
In order to investigate the relationships between the responses of four crops (rice, soybeans, potatoes, and red pepper) to acid rain, the simulated acid rain(SAR) of pH 1.8, 2.3, and 2.8 and normal rain of pH 6.0 were applied from 30 days after emergence to harvest at the two-week interval for rice, soybeans and red pepper and at a week interval for potatoes. SAR of pH 1.8 and 2.3 caused brown spots in the leaves of rice, soybeans, and red pepper and the damages were severer as the pH of SAR lowered, while no visual damages were observed in potatoes. The SARs did not affect chlorophyll content of rice and potatoes, while chlorophyll content of soybeans and red pepper decreased as the pH of SAR lowered. Photosynthetic activity was not significantly different among the pHs of SAR in rice, while decreased as pHs of SAR lowered from pH 2.8 to 1.8 in soybeans, potatoes, and red pepper. Yield of rice, soybeans, and potatoes was not affected by the pHs of SAR, but in red pepper the length, diameter, and weight of a fruit, the number of fruits per plant, and total matured fruit yield decreased as the pHs of SAR lowered. In rice and potatoes visual damages caused by SAR did not correlated with other observed traits. However, visual damages were negatively correlated with chlorophyll content and photosynthetic activity of soybeans and photosynthetic activity and yield of red pepper.
Underdrainage Effects on Soil Salinity and Growth of Rice in Gyehwa Reclaimed Saline Land
KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 61~67
This experiment was carried out from 1979 till 1983 to elucidate the underdrainage effect on soil salinity and growth of rice plastic underdrainage was established 5m and 8m intervals in April of 1979 and Jinjubyeo the medium maturing rice variety was transplanted by hand at late of May. The results are as follow; The desalination effect was higher in 5m interval underdrainage than 8m interval underdrainage and the salt content was lower than 0.3％ at 1 year after in 5m interval, 2 years after in 8m interval underdrainage and 3 years after at control. Farther the distance from underdrainage position, less the desalinization rate that desalinization was least at center part of the underdrainage position. Desalinization effect was highest 30cm of soil depth and decreased deeper than it. Shorter the underdrainage interval, more the panicle number, heavier 1, 000 grain weight and higher the milled rice yield. But the milled rice yield wasn't significantly different between the underdrainage interval from 3 years after underdrainage.
Difference of Absorption and Anatomical Responses to Protoporphyrinogen Oxidase-Inhibiting Herbicides in Wheat and Barley
KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 68~78
Laboratory and greenhouse studies were conducted to determine differential sensitivities on absorption of
C-oxyfluorfen and the anatomical responses in wheat and barley to protoporphyrinogen oxidase-inhibiting herbicides [oxyfluorfen (2-chloro-1- (3-ethoxy -nitrophen-oxy)-4-(trifluoromethyl) benzene, acifluorfen(5-[2-chloro-4-(trifluoromethyl) phenoxy]-2-nitro-benzoic acid), bifenox(methyl-5-(2, 4-dichlorophenoxy)-2-nitrobenzoate) and oxadiazon(5-tert-butyl-3-(2, 4-dichloro-5-isopropoxyphenyl)-1, 3, 4-oxadiazol-2-one)]. I
value of the tolerant wheat cultivars to oxyfluorfen was about 10
, whereas that of the susceptible barley cultivars was about 10
M, showing significant difference between the two groups. When foliage were applied with acifluorfen, bifenox or oxadiazon, the oxyfluorfen-tolerant wheat showed less decreased in shoot fresh weight and chlorophyll content than the susceptible barley. Also, when soil-applied with these herbicides test plants showed similar tendency in foliar application. Electrolyte leakage from the tissue treated with these compounds was the more influenced in the barley than the wheat. Malondialdehyde(MDA) production as index of lipid peroxidation was greater in the barley than the wheat by treatment of these compounds. Therefore, the differential sensitivities of wheat and barley to protoporphyrinogen oxidaseinhibiting herbicides was showed by our greenhouse and in vitro experiment. The absorption rates of
C-oxyfluorfen were higher in the barley than the wheat. And this tendency was showed appararitly difference by increase of treatment durations. After the oxfluorfen and oxadiazon treatment, the tolerant wheat did not show the structural damage in leaf surface, but the susceptible barley was damaged in the leaf waxy layer. However, the acifluorfen and bifenox treatment showed no difference between wheat and barley. The anatomical changes by these compounds treatment were not observed in the tolerant wheat but epidermal cell and mesophyll cell were highly broken in the susceptible barley.
Difference of Protoporphyrin IX Accumulation and Antioxidative Activity of Wheat and Barley by Protoporphyrinogen Oxidase-Inhibiting Herbicides
KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 79~88
This experiment was conducted to investigate the protoporphyrin Ⅸ (PPIX)accumulation, activity of antioxidative enzymes and contents of antioxidant in tolerant-wheat and susceptible-barley to protoporphyrinogen oxidase (Protox) inhibiting-herbicides [oxyfluorfen(2-chloro-l-(3-ethoxy-nitrophenoxy-4-(trifluoromethyl) benzene, acifluorfen (5-[2-chloro-4-(trifl-uoromethyl) phenoxy]-2-nitrobenzoic acid), bifenox(methyl-5-(2, 4-dichlorophenoxy) 2-nitroben-zoate), and oxadiazon (5-tert-butyl-3-(2,4-dichloro-5-isopropoxyphenyl)-1,3,4-oxadiazol-2-one)]. The tolerant-wheat and susceptible-barley were soaked in these compounds at 10
M for 2hrs and exposed to light for 2,4,6 or 8hrs to investigate change of the activity of antioxidative enzymes. The activities of monodehydroascorbate reductase(MDAR), catalase(CAL) and superoxide dismutase(SOD) were lower in the barley than in the wheat after the treatement of these compounds. The activity of peroxidase(POX) was lower in the barley than in the wheat at 8hrs after the treatment of oxyfluorfen but other compounds showed no difference in activity in wheat and barley. The activity of glutathione reductase(GR) was increased in wheat and barley according as hours of treatment of these compounds became increased but its activity was no difference between wheat and barley. In the case of the content of vitamin C due to the treatment of these compounds, the wheat decreased less than the barley. After the treatment of oxyfluorfen the content of vitamin E in the wheat was higher than in the barley but other compounds didn't have any difference between wheat and barley. And after the treatment of acifluorfen the content of carotenoid was greater in the wheat than in the barley but other compounds didn't have any difference between wheat and barley. The content of glutathione (GSH, GSSG) was greater in the barley than in the wheat. The content of protoporphyrin Ⅸ (PPIX) accumulation by the treatments of these compounds was more in the barley than in the wheat. Especially, the treatment of oxyfluorfen and acifluorfen were more accumulated 2.3 and 1.3 fold in the barley than in the wheat, respectively.
Effect of Drought Stress at Various Growth Stages on Soybean Growth and Yield
KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 89~94
The present study was conducted to know the growth and yield of in response to the drought stress at the different soybean growth stage. Drought stress was given to the soybean plants on early vegetative growth at fourth-node stage(FNS), mid-growth at beginning pod stage(BPS) and late growth at beginning seed stage(BSS) for 30 days, which are high availability in soil water stress on climate condition of Korea. Dry weight was decreased severely by water stress at FNS, and BPS and BSS has no difference compared to control. Chlorophyll content of leaf severely decreased at the end of water stress of FNS and BPS, but was recovered at the harvest stage. Drought-stressed root distributed mainly near the soil surface and number and dry weight of root nodule were decreased severely by drought stress at BPS. Number of pod, seed weight and yield were decreased by drought stress and showed the highest yield loss at BPS.
Effects of Ice Cooling Storage on Chemical Components in Vegetable Corn
KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 95~103
This experiment was carried out to obtain the basic information necessary to establish suitable postharvest handling techniques and to keep high quality of the sweet(Danok 2), supersweet(Cooktail 86) and waxy(Chalok 1) corn which are mainly consumed as vegetable in Korea. Vegetable corns were cooled with ice fragments in the insulation box immediately after harvest and stored in low temperature warehouse at 0 to 2
. During the 15 days short-term storage, changes of chemical components were compared with those of uncooled corns. The losses of moisture in kernels were as high as 7.4 to 24.4％ in uncooled corns while those of ice cooled corns increased 0.4 to 0.5％ of their weight. The ratio of pericarp and alcohol insoluble solid(AIS) content increased as the storage days prolonged in all treatments but increasing rates were much higher in uncooled samples. On the other hand, the total sugar loss during storage was the least in supersweet corn when they were cooled with ice fragments in insulation box. After 5 days storage, the ice cooled samples showed the highest free amino acid contents compare to those of uncooled and stored at room temperature (25 to 3
) or low temperature warehouse, and
-aminobutylic acid (GABA) which was known as a fuctional amino acid was detected in all three kinds of vegetable corns.
Effect of Clipping Time on Seed Maturity and Germination in Italian Ryegrass (Lolium multiflorum Lam. Italicum)
KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 104~111
Since seeds of Italian ryegrass should be imported every year, it is necessary to investigate the prossible production of seeds in Italian ryegrass field after rice. Seven Italian ryegrass varieties were planted on October 8, 1986 at National Honam Crop Experiment Station at Iksan and clippings were made on April 10 and April 30 in 1987. Headings of K-11 and T.N.T were earlier than those of Tetrone and Bettina. For all varieties tested, heading date was delayed and 1,000 grain weight was decreased linearly as the clipping was made later. Length, width and thickness of a grain were reduced by clipping and later clipping, while tetraploid varieties produced larger grains than diploid varieties. The germination percentage and germination speed at
were higher than at 15
. The final germination percentage was lower at the later clippings and was higher at 15
, and earlier varieties showed higher germination percentage. Uniformity of germination was greater at
and was decreased as the clipping was made later, and the eariler varieties such as K-11 were germinated more uniformly. Average number of days to germination was longer at 15
and was longer at later clipping. The germination percentage was decreased linearly as the heading was delayed, while it increased linearly as the 1,000 grain weight was increased.
Effect of Desalinization on Early Seedling Growth of Winter Barley in New Tideland
KOREAN JOURNAL OF CROP SCIENCE, volume 42, issue 1, 1997, Pages 112~118
This study was conducted to obtain basic information on the desalinization in newly reclaimed tideland. A desalinization experiment with leaching method was carried out using the soil samples collected in Haenam tideland, and the early growth response of winter barley to salt stress during the desalinization was investigated by measuring emergence rate, plant height, leaf area and fresh weight. The soil in Haenam tideland was saline-sodic with 59mS / cm of electrical conductivity and pH 8.0, and the soil texture was silty loam with 16％ clay and 75％ silt. Depth of water for desalinization(DWD) to decrease the electrical conductivity below 4mS /cm was 140mm in 5cm depth soil and 240mm in 20cm depth soil. The value of pH of soil and leaching water increased from 8.0 to 8.3 until the electrical conductivity decreased to about 6mS / cm during the desalinization. .The emergence rate of winter barley was over 75％ in the DWD above 80mm and showed no significant difference with the DWD. The DWD for the normal growth of winter barley seedling was above 120mm at 1 and 2 weeks after sowing(WAS), and above 160mm at 3 and 4 WAS. The leaf area and fresh weight showed no response for salt stress with the DWD above 12mm at 2 WAS, and above 16mm at 3 WAS. It was estimated that the electrical conductivity of soil saturation extract for the normal growth of winter barley during early seedling growth stage in new reclaimed tideland would be below 9mS / cm in 20cm depth soil.
