自1983年以来,我们对大豆抗旱性的鉴定指标进行了一些探讨。实验室的测定指标有:叶片保水力的测定,叶片茸毛的观察,电导率的测定,种子萌发出土试验和高渗溶液萌发试验。大田指标有苗期根茎比的测定和干旱棚内苗期抗旱品种的筛选。据A.Blum报道,从小麦、大豆和水稻
Since 1983, we have done some research on the identification index of soybean drought resistance. Laboratory determination of indicators are: Determination of leaf water retention, leaf hair observation, conductivity measurement, seed germination unearthed test and hypertonic solution germination test. Field indicators have the determination of seedling rhizome ratio and screening of drought-resistant seedlings in drought shed. According to A.Blum reports from wheat, soybeans and rice
