Effects of Stem Extracts from Perilla and Buckwheat on Seed Germination and Seedling Growth of Barnyard grass and Chinese Cabbage

들깨 및 메밀의 건경추출액이 피와 배추의 발아 및 초기생장에 미치는 영향

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.

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.
