Response of Flax Varieties to Planting Density

아마품종의 재식밀도 반응

Under the different conditions of planting density, maturation dates, stem length, oil contents, stem yield and seed yield of flax were investigated in 1984. The results were as followed: Wiera and Storment Goss were earlier in the maturation dates with increasing plant density, However Taijungsung #1 was delayed. Though there is a difference between the varieties stem length was getting longer with increasing plant density., Oil contents were getting higher with increasing plant density, stem yield and seed yield were increased with increasing plant density, on the contrary those were decreased by the growth of ciliary flax in the case of 1200 plants per 1.2m$^2$. Therefore optimum planting density of flax culture was 12cm x 6cm.

재식밀도 차이에 따른 Wiera 등 3품종의 성숙기, 경장, 유분함량, 원경중 및 종실중 변화를 시험한 결과를 요약하면 다음과 같다. 1. Wiera와 Storment Goss는 밀식할수록 숙기가 단축되었으나 Taijungsun #1은 늦어져 조숙종과 만숙종의 성숙기에 대한 반응이 달랐다. 2. 품종에 따라 차이는 있으나 밀식할수록 경장이 길어지는 경향이었다. 3. 유분함량도 밀식할수록 높아지는 경향이었다. 4. 원경중과 종실종은 밀식할수록 증수되었으나 1.2m$^2$당 1,200주 이상으로 밀식할 때는 모아마의 발생으로 오히려 감수되었다. 따라사 아마재배의 적정재식밀도는 휴간 12cm$\times$주간 6cm(600주/1.2m$^2$)이었다.
