大豆农艺性状与抗旱性研究

Studies On Agricultural Property And Drought-resistance of Soybean

选用山西农业大学大豆研究室具有代表性的10个品种,在水、旱(胁迫)条件下进行不同大豆品种农艺性状抗旱性研究。对生育期、株高等农艺性状进行抗旱性综合分析,利用抗旱隶属函数值对大豆抗旱级别进行了划分,分析结果表明,不同大豆品种的农艺性状对抗旱性及后期产量形成具有一定的影响,每个与抗旱性有关的农艺性状对大豆抗旱性起着重要作用,对于筛选大豆抗旱性材料具有指导意义。

In this test 10 species ot representative soybean from soybean research of shanxi agricultural unversity were slected, and drought resistance analysts of different soybean in varies＇ agricultural properties such as growth period , plan theight etc. under water and drought （stressing） situations were carried out. Meanwhile the subordinate function value was used to classify the classes of soybean＇s drought-resistance. The result of this test shows, that different soybean varieties have some influences on the drought-resistance and the yield the later stage. Each agricultural property which is related with the drought-resistance nature could play an important role in the soybean drought-resistance, and could be of great guid significance in screening the materials of soybean drought-resistance.
