PE 필름 피복 재배가 땅콩 생육 및 종실의 단백질 , 지방함량과 지방산 조성에 미치는 영향

Flowering date of peanut variety, Daekwangtangkong and Daepungtangkong in non-mulching culture was delayed each 9 and 6 days. Seedling ratio was decreased each 3.7%, 16% and branch length was decreased each 24%, 17% more than polyethylene film mulching culture. But the number of branch in non-mulching culture was not reduced. No. of mature pods, kernel/pod ratio, 100-seed weight and kernel weight per plant was reduced extremely in non-mulching culture, nevertheless the kernel yield per 1 ㏊ of Daekwangtangkong in non-mulching culture was similar to that of polyethylene film mulching culture but yield of Daepungtangkong wat 26% higher than that of polyethylene film mulching culture owing to planting density. Protein content of Daekwangtangkong in non-mulching culture was increased 4% but that of Daepungtangkong was decreased 3% and oil content of both variety was decreased 7%, 9% respectively comparing to polyethylene film mulching culture. Oleic acid was increased but linoleic acid was decreased and O/L ratio was decreased in non-mulching culture.
