들깨 및 메밀의 건경추출액이 피와 배추의 발아 및 초기생장에 미치는 영향
成洛戌,韓義東,禹然洙 韓國作物學會 1987 Korean journal of crop science Vol.32 No.4
들깨 및 메밀 건경의 물 추출액을 피 및 배추에 처리하여 발아 및 초기생장의 억제 양상을 본 결과 1. 두가지 추출액 모두 피와 배추의 발아를 억제하였으며 메밀 추출액이 들깨 추출액보다 심하였고 피보다는 배추에 억제효과가 켰다. 2. 발아후 초기 생장도 위와 같은 경향이나 발아억제보다는 생장 억제 효과가 약간 적은 영향이었다. 3. 이들 추출액은 지상부 생장보다는 뿌리 생장에 피해를 더 주는 경향이며 들깨 추출액보다 메밀 추출액이 더 심한 편이었다. The present study was conducted to investigate the effects of stem extracts from perilla and buckwheat on the germination and seedling growth of barnyard grass and chinese cabbage. The major results obtained are as follows. The stem extracts showed inhibiting effects on seed germination. The degree of inhibition was much higher with the extracts of perilla than those of buckwheat and more sensitive to chinese cabbage than barnyard grass. The trends of inhibition effects on seedling growth were the same as in the seed germination with lower degree. The roots were more sensitive to the extracts than the tops with higher degree with buckwheat extracts.

To reexamine taxonomic status of endemic Mogera wogura coreana from Korea, we first obtained partial 12S rRNA sequences (893 bp) and complete cytochrome b gene sequences (1140 bp) of this subspecies, and these sequences and partial cytochrome b sequences (402 bp) were compared to the corresponding haplotypes of M. wogura from East Asia, obtained from GenBank. The one of three 12S rRNA haplotypes in M. w. coreana was identical to one 12S rRNA haplotype of M. w. robusta from East Asia: 10 complete and 13 partial cytochrome b haplotypes of M. w. coreana formed a single clade with one complete and four partial cytochrome b haplotypes of M. w. robusta,respectively. We considered that M. w. coreana from Korea is an endemic subspecies with only morphological differences, although it is necessary to reexamine the subspecies status of M. w. coreana. Additionally, in the 12S rRNA and complete cytochrome b sequences, M. wogura from Japan was distinct from the two continental subspecies of M. w. coreana and M. w. robusta with average distances of 1.76 and 5.65%, respectively; insular M. wogura, with within-group distances of 2.09 and 4.38%, respectively, was also genetically more divergent than the mainland M. wogura, with within-group distances of 0.08 and 0.57%, respectively. Thus, we considered that insular M. wogura of Japan dispersed into neighboring East Asian continent, which is opposite to the traditional hypothesis on the origin of Japanese M. wogura.
들깨의 채엽회수와 시기가 생육특성 및 종실수량에 미치는 영향
方鎭淇,李正日,韓義東 한국작물학회 1990 한국작물학회지 Vol.35 No.6
들깨의 종실·엽 겸용 신품종인 '엽실들깨'를 공시하여 정식기별로 채엽회수와 채엽시기를 달리할 경우 생육특성, sink 관련형질 및 종실수량에 미치는 영향을 구명하기 위해 시험을 실시한 바 그 결과를 요약하면 다음과 같다. 1. 상품가치가 있다고 보여지는 충분히 전개된 잎을 대상으로 채엽한 결과 경장은 무채엽구에 비하여 작아지는 경향이었다. 2. 채엽이 경태, 절수, 분지수 등에는 크게 영향을 주지 않았다. 3. 채엽에 의해 sink 관련형질인 화방수, 천립중을 감소시켜 종실수량이 낮아졌으며, 채엽회수가 많을수록 채엽시기가 늦을수록 영향이 큰 경향이었다. 4. 종실·엽 겸용 들깨재배시에는 종실수량 감소가 크지 않고 채엽에 의한 소득이 증대될 수 있는 조기채엽이나 1-2회 채엽이 바람직하였다. 5. 재배목적이 종실과 엽을 동시에 생산하고자 할 경우에는 5월 10일 파종 6월 20일 정식이 가장 적기이며, 6월 10일 파종 7월 20일 정식까지는 재배가 가능할 것으로 보였다. This experiment was conducted to obtain some informations on the effects of number of leaf harvest and time to agronomic characters and grain yield in perilla. For the experiments perilla seedlings of 40days old were transplanted on June 20, July 20 and August 20 in 1988, and leaf harvested at 30. 40. 50 and 60 days after transplanting, respectively. The following results were obtained from the experiments. In the case of the fully developed leaves were harvested, culm length were decreased by more harvests and by the later harvests. However culm diameter, number of nodes and branches were little influenced by the leaf harvests. Number of clusters, weight of 1,000 grain and grain yield were significantly influenced by the number of leaf harvest and time. As the above results, considering the grain yield, leaf harvest would be available in the case of once or twice at the early growing stage.
