국문 초록

구약감자 5개 수집종에 대한 생리 생태적 특성을 요약하면 경장, 경태는 일본 수집종이 가장 컸고 분지수는 국내수집종인 제천종이 각각 3.1개 3.6개로 가장 많았다. 출하일수는 일본수집종 및 중국수집종이 60일로 제천수집종에 비해 3-5일 빨랐다. 출하율은 일본종이 90%로 금산, 제천종보다 5-10% 높았다. 엽면적은 일본수집종이 가장 넓었으며, 광합성 능력도 엽면적이 넓은 일본수집종이 전기간에 걸쳐 가장 높았다. 엽록소 함량은 관행(자연광) 대비보다 차광율이 높을수록 엽록소 함량이 높았다.

영문 초록

This research was performed to understand physiological and ecological characterisities and to de stable production by the way of the establishment of cultivation in elephant food. The results of the investigation of developmental characterisitics, leaf area, photosynthetic ability, chloroplast content for collective varieties are as follows. In the ecological characterisrics for five varieties of elephant food collected from domestic and foreign countries, appearance days for Japanese collective varieties was 60 days, which was two days earlier than domestic collective variety, Jechon collective variety. In appearance rate, Japanese collective variety was 90%, which was higher than Kumsan collective variety, 85%. In the development and yield of the ground portion, Japanese variety was the highest during all developmental period follwed by Chinese and Jechon collective varieties. The larger leaf area, the higher photosynthesis was found. In the amount of chlorophyll content, the higher intercepting light rate, the higher chlorophyll amount was found, which was 30, 50, 70% higher amount than non intercepting light rate.
