온도조건과 광의 유무에 의한 소리쟁이속 잡초종자의 발아특성을 조사한 결과, 발아 시작점은 참소리쟁이가 치상 4일 후로 가장 빨랐으며 돌소리쟁이(5일), 소리쟁이(6일), 좀소리쟁이(10일)의 순으로 나타났다. 소리쟁이속 잡초의 최적 발아온도는 공시 잡초종자 모두 $15^{\circ}C$에서 가장 높은 발아율을 보였으며, 돌소리쟁이가 $10^{\circ}C{\sim}30^{\circ}C$까지 높은 발아율을 보여 온도에 있어 가장 넓은 발아스펙트럼을 가지고 있는 것으로 나타났다. 1996년 수집하여 저온저장한 참소리쟁이와 2004년 수집된 참소리쟁이 간의 종자생존력을 비교한 결과, 두 초종간의 유의차는 인정되지 않아 참소리쟁이는 저온저장 할 경우 8년 이상의 종자생존력을 가지고 있는 것으로 나타났다. 조사기간 중 암조건에서 수행한 모든 처리에서 발아는 보이지 않았다. 소리쟁이속 잡초의 발아특성을 수량화한 결과, 참소리쟁이는 다른 소리쟁이속 잡초에 비해 가장 높은 누적발아율을 보이며 발아에 균일성을 보였다. 돌소리쟁이는 참소리쟁이나 소리쟁이에 비해 발아에 걸리는 평균일수나 발아속도가 가장 빠른 것으로 나타났다.

Research was initiated to investigate germination characteristics and germination pattern of 14 herbaceous plant entries used on the road slope during 30 days. An alternative germination condition for 14 herbaceous plant entries required by International Seed Testing Association(ISTA) was applied in the experiment, consisting of 8-hr light at $25^{\circ}C$ and 16-hr dark at $15^{\circ}C$. Significant differences were observed in the first germination rate(0.3%~40.7%)and in the final germination rate(7.7%~93.3%). Days to the first germination(2~8days), days to the 30% germination(2~6days) and days to the peak germination(6~18days) were different among 14 herbaceous plant entries in the study. From this result, we could find out higher final germination rate of 14 herbaceous plant entries in the following order; First, forage crops and cool-season turfgrasses; Second, herbeceous flowers; Third, wild plants. We could also divide germination rate among 14 herbaceous plant entries as 6 groups(I;very high, II;high, III;medium high, IV;medium low, V;low, VI;very low) based on the final germination rate and divide germination speed as 5 groups(A;very fast, B;fast, C;normal, D;slow, E;very slow)based on days to the peak germination. Considering germination characteristics and pattern of 14 herbaceous plant entries Medicago sativa, Lolium perenne, Festuca arundinacea and Cosmos sulphureus were regard as dominating species while Lespedeza cuneata, Silene armeria, Lotus corniculatus var.japonicus, Coreopsis tinctoria and Centaurea cyanus as competitive species following dominating species. However, Chrysanthemum burbankii, Pennisetum alopecuroides, Chrysanthemum boreale., Artemisia princeps var. orientalis and Arundinella hirta were not almost expected to emerge.

Soybean seeds were treated with blue, red and far-red lights for 0, 6, 12, and 24 hours during 24-hour imbibition before culture for 6 days. The soybean sprouts raised were classified by their hypocotyl lengths; normal (＞4cm), abnormal (＜4cm) and non-germination, and their lateral roots, hypocotyl diameters and component dry weights were measured. Red light treatment and dark imbibition reduced the abnormal soybean sprouts more than far-red and blue light treatments, meaning that the former treatments produced more commercial sprouts. The lateral roots were more formed in blue light and dark imbibition than the other light treatments, but were completely blocked by any light treatment lasted during the whole imbibition. Although any light quality treatment did not influence their primary root lengths, blue light one lengthened the hypocotyl more than the others treated during the imbibition, and far-red light enlarged its diameter. Despite this morphological change, component, total or economic yield was not significantly different among the light quality treatments during the imbibition.

Seeds of burcucumber were treated with accelerated aging, cold-stratification, and light quality illuminated during desiccation to enhance their germination and seedling emergence. The germination was increased by aging and cold-stratification although the latter treatment showed greater effectiveness than the former one. In the combined treatment of aging 6 days at $45^{\circ}C$ and cold-stratification, the germination was promoted under longer period of cold-stratification to reach nearly 100% in 3 week cold-stratification on the ninth day from sowing. In the sequentially combined treatment of aging, cold-stratification, and light quality during 24 hour desiccation at $35^{\circ}C$, no-stratified seeds showed the highest rate in red light treatment but the lowest in far-red light. This implies that the phytochrome action run during the desiccation of imbibed seeds. The red light exposure during drying for the cold-stratified seeds after aging accelerated the germination even more than the dark treatment and germinated 100% on the next day of sowing. It is concluded that the sequential treatment of aging, cold-stratification, and red light illumination during desiccation can highly promote percentage and speed of burcucumber seed germination.

Ethanol extracts of Mung Bean seeds and seedings were analysed by 2-dimensional and circular paper partion chromatography for Nitrogen compounds as a part of the study on the Amino acids metabolism. In the seeds, 18 ninhydrin positive substances were present, before germination, but the number increased to 21 after germination. There were 3 unknown substances and one of it formed newly after germination. After 2-days germination, the amount of amides, such as Asparagine and Glutamine. where increased very large which were very small amount before it. Those were accumulated more in dark place than in light and the amount of Asparigine were more than that of Glutamine. Through the germination, there were large amount of Glutarmic acid, Aspartic acid and Alanine which seems to be concerned in transamination reaction in seedings. Valine, Leucine, and Phenylalanine increased to considerable amount after germination. This is very remarkable fact as those Amino acids were reported to be concerned in transamination reaction recently. ${\gamma}$-amino butyric acid was detected in both Cotyledon and Embroy through the germination. It seemed that there is no any Nitrogen Metabolism in the unbroken seed even if it is preserved very long period.
