This study was conducted to investigate how a labor saving for conventional hand sowing and respond to major agronomic traits under different planting density in 1993 and 1994. Each trial was a randomized block split plot with row spacing as the main plots and hill spacing as subplots. Sowing rate appeared lower in 20 or 25cm hill spacing using machine seeder than in hand sowing. Sowing time required reduced more 121 hours per hectare in 60cm row, 20cm hill spacings using machine seeder than in hand sowing. Increasing row and hill spacings reduced number of seedling stand per unit
. Both number of pods per plant and grain weight per plant and showed highly increase in wide planting. Best yield obtained in 60cm row, 20cm hill spacing using machine seeder. Accumulative mean air temperature was positively correlated with stem height, number of pods per plant and yield, otherwise accumulative rainfall was negatively correlated with ones. A highly significant negative correlation was showed between number of seedling stand per unit
and number of branches, number of pods per plant, grain weight per plant and yield. Yield was positively correlated with number of branches, number of pods per plant and grain weight per plant.

Phytochemical analysis on rice bran and its pitch was performed by the tool of TLC, UV- and IR-spetroscopy, so that it was found that they contained
and free sterol. GC-MS analysis of free sterol revealed that it was composed of
, campesterol and stigmasterol. Successive phytochemical analysis of
revealed that it was composed of ferulic acid ester of triterpene and sterol, respectively. Triterpene moieties of
were identified as follows: cycloartanol, cycloartenol, 24-methylenecycloartanol and unknown triterpene; And sterol moieties were found to be identical with free sterols. In addition, characteristic absorption band in UV spectrum (220-340 nm) was exclusively due to
. Thus, it was suggested that rice brans of nearly all species of Oryza sativa can be quantitatively analyzed by UV absorption spectrometry, even when water soluble pigments was contained in the rice bran.

Treatment of ethylacetate extract of Asiasarum sieboldi inhibited the germination and the growth of radish seeds. Two phenylpropanoids were isolated from ethylacetate extract. Their structures were identified as safrole and o-methyleugenol by spectroscopic evidence. From the test to inhibitory effect, o-methyleugenol had inhibited the germination and the growth of radish seeds, while safrole did not. The germination rate and radicle length of radish seeds were decreased to 63.0%, 31.5 % of control at 5mg/ml of o-methyleugenol, respectively. At the same concentration, o-methyleugenol inhibited the hypocotyl growth up to 100%.

Campanulaceae having the most growing areas among medicinal crops cultivated in Korea occasionally failed to establish a reasonable standing in practice. The experiment was carried out to examine the effect of prechilling (0 : 4 : 8 days), light quality (red : white : dark) and daily irradiation hours (8 : 12 : 16) after sowing on seed germination and radicle elongation of Campanulaceae (Platycodon grandiflorum : Codonopsis lanceolata : C. pjlosula) to give an information on their earlier standing establishment. Mean germination rate of P. grandiflorum was the highest but that of C. pilosula was the lowest regardless of all the treatments. 12 hours irradiation or prechilling increased to 8 days enhanced their earlier or later germination, respectively. White light increased the rate of P. grandiflorum but alleviated that of C. lanceolata regardless of the daily irradiation hours. Although prechilling eliminated such effect of white light, light quality treatment effect on their mean germination rates was influenced by period after sowing, daily irradiation hours or prechilling. On the 9th day after sowing, C. lanceolata showed the greatest radicle length, and both daily 8 hours irradiation and 8 days prechilling enforced to elongate their radicles, while P. grandjflorum and C. lanceolata more lengthened their radicles in all prechilling treatments than in no chilling but C. pilosula showed the similar result only in the 8 days prechilling.

Priming has been used to establish a better standing in practice as controling the seed moisture content after sowing. The experiment was done to measure the effect of priming (material ; concentration ; period) and light quality (red ; white ; dark) after sowing on seed germination and radicle elongation of Campanulaceae (Platycodon grandiflorum ; Codonopsis lanceolata ; C. pilosula) to give an information on their earlier standing establishment. The germination test was carried out with 12 hours irradiation for 9 days after priming treatment. In the darkness, the mean germination rate of all the species was decreased in the order to P. grandiflorum, C. pilosula, C. lanceolata. Their germination and radicle elongation became more inclined when primed with
or with 50 to 150mM than with
or no priming although there was no difference between priming periods. Under irradiation during their seed germination, however, the former order was changed to P. grandiflorum, C. lanceolata, C. pilosula because light quality treatment given after priming reduced the rate of C. pilosula but enhanced that of C. lanceolata. Although light quality forced after priming did not affect the mean germination rate of P. grandiflorum, it increased earlier or alltime germination of C. lanceolata or C. pilosula, respectively. White light after priming repressed germinations of C. lanceolata and C. pilosulai but increased earlier germinatin of P. grandiflorum, meaning that seed germination and radicle elongation of Campanulaceae could be determined by light quality treated after priming.

This experiment was carried out to clarify the effect of different fertilizer on growth and yield of Fritjllaria thunbergii in Chungbuk Rural Development Administration from 1993 to 1995. Emergence date was faster about 1 to 5 days in fertilizer application than that of non-fertilizer, and emergence ratio was lower about 2.4% to 35.7% in fertilizer application than that of non-fertilizer. Plant height was longer about 2.8cm to 10.6cm in fertilizer application than that of non-fertilizer, and leaf length and width had same tendencies. Bulb height was increased about 0.1 to 0.2cm in fertilizer application than 1.9cm in non-fertilizer and bulb width was increased about 0.5 to 0.7cm in fertilizer application than 2.2cm in non-fertilizer. Total yield was increased about 27% in N-P-K fertilizer, 24% in compost, 23% in compound fertilizer for garlic and 21 % in fowl dropping manure than 572kg/10a in non-fertilizer. Yield of marketable goods was high about 79% in compost. 72% in compound fertilizer for garlic and fowl dropping manure, and 69% in organic fertilizer than 229kg/l0a in non-fertilizer. Therfore, in the cultivation of Fritillaria thunbergii the application of organic fertilizer such as compost and fowl dropping manure was considered more profitable than the application of chemical fertilizer in middle region.

The germination inhibitory effects of American ginseng (Panax quinquefolium Linne) pulp were discussed. The germination inhibitory effects of pulp juice were decreased in a concentration dependent manner. When the pulp juice was diluted 0 (original juice), 1, 2, 5, 10, 20, 50 and 100 times, the radicle lengths of the assay plant, Chinese cabbage (Brassica chinensis Linne), showed 0, 0.32, 0.72, 3.13, 4.83, 16.07, 16.73 and 23.50 mm, respectively (CK=25.98 mm). The pulp evidently inhibited the embryo growth in natural fruit. The longer was the duration that the pulp stayed around the seed, the longer was the time course needed for embryo getting free from the inhibitory effects of pulp. When the depulping was performed on the day 0, 15, 30 and 60 after harvest, the time courses needed for embryo extricating the residual inhibitory effects from pulp were 30, 75, 135 and 135 days, respectively. Moreover, if the pulp stayed around the seed with time, that would make the seed rotten ratio increase. When the pulp stayed around the seed for 0, 15, 30, 60 and 270 days, the seed rotten ratios were 5.47, 5.71, 19.05, 27.14 and 33.33%, respectively. Therefore, we concluded that the pulp could be included in the inhibitory components which made American ginseng seed get into dormancy.

Variations in growth and yield of adlay(Coix lachyma-jobi var. ma-yuen Stapf) was monitored in farmer's fields in Yunchon, the main producing area in Korea, where the field condition showed difference in topograyphy, crop rotation, and ridge shape. Rotation cropping increased remankably stem length, and number of effective tillers, reduced the occurrence of leaf blight and crop damage by the disease, and in addition showed positive effect to repress the occurrence of stem-borerin upland field. Stem length was greater in upland field than in paddy field and this result seemed to be related to lodging degree. The even field with crop rotation system showed the highest seed yield and followed by hillside field and paddy field resulted the lowest yield.
