生長調節劑가 大豆의 生育 및 收量에 미치는 影響 = Effects of Growth Regulating Chemicals Upon the Growth and Yield of Soybean

국문 초록 (Abstract)

本 硏究는 晋州産業大學校 田作 實習圃場에서 995年 6月부터 10日까지 새알콩을 供試品種으로 하여 Ethrel, B-9, BA, NAA 등의 生長調節劑로 각각 3濃度의 용액을 開花始에 噴霧 處理하여 生育 및 收量을 調査하였던 바 그 結果를 要約하면 다음과 같다.
1. 莖葉 處理가 生育 形態에 미치는 影響
1) 莖長은 無處理區에 비하여 處理 濃度가 增加함에 따라 短縮되는 傾向이었으며 BA 200ppm의 處理區가 10.3cm의 가장 큰 短縮 效果를 나타내었다.
2) 莖直徑, 莖重, 主莖節數는 NAA처리구가 增加시키는 傾向은 있었지만 統計的인 有意差는 認定되지 않았다.
2. 莖葉 處理가 收量 形質에 미치는 影響
1) 結莢數는 Ethrel 1000, 2000培액 處理區와 BA 150, 200ppm處理區에서 無處理區보다 增加하였으나 統計的인 有意差가 없었다.
2) 株當 粒數가 100粒重에 있어서는 全處理區가 無處理區에 비하여 增加하는 傾向이 있었고, 그 중에서도 NAA處理區가 가장 많은 粒數와 100粒重을 나타내었다.
3) 種實重은 NAA 30ppm處理區가 증수 效果가 가장 높게 나타내었으며 BA 100, NAA 20ppm, Ethrel 1000培液順으로 증수되었다. 따라서 大豆 收量을 增大하기 위해서는 開花始에 NAA 30, BA 100ppm을 莖葉 處理하는 것이 效果的인 것으로 나타났었다.

The purpose of this study is to examine the effects of such growth regulators as Ethrel, B-9, BA, and NAA upon the growth and yield of soybeans. The regulator solution was made in a level concentrations, and sprayed at the flowering time. The experiment was carried out at the experimental field of Chinju National University from June till October 1995.
1. Effects upon the growth characters:
1) The stem length tended to be shortened according as the regulator concentration became higher. The BA-200 ppm-treated lot showed the shortest stem length(10.3cm)
2) The stalk diameter, the stem weight and the knot number tended to increase in the NAA-treated plot. But the changes were not on a statistically significant level.
2. Effects upon the yield characters:
1) The number of pods increased in Ethrel-1000, Ethrel-2000, BA-150 and BA-200 plots. But the increase was not statistically significant.
2) The grain number per plant and the 100-grain weight increased in all of the treated plots. The NAA plot showed the largest grain number and the heaviest weight.
3) The seed weight per hill was heaviest in the order of NAA-30, BA-00, NAA-20, Ethrel-1000 plots. Therefore, NAA-30 and BA-100 ppm treatments at flowering season are considered to be effective for increasing yield.
