大豆的耐旱性是干旱和半干旱地区大豆高产稳产的主要因素之一.提高大豆品种的耐旱性,是这类地区农业研究中的重大课题.为此,就国外有关大豆耐旱性及其筛选方法的研究简述如下. 一、大豆对水分胁迫的反应大豆籽粒的个体发育是产量形成过程中的一个重要组份.评定环境因子对籽粒个体发育的影响对深入了解环境对产量的影响是必要的.L.Me ckel等人1984年指出,籽粒
Drought tolerance of soybean is one of the main factors of high and stable yield of soybean in arid and semi-arid areas.Improving the drought resistance of soybean varieties is a major issue in agricultural research in this area.Therefore, The research methods of screening are as follows: A. Response of soybean to water stress The individual development of soybean grain is an important component in the process of yield formation.Evaluating the impact of environmental factors on the individual development of grain To understand the effects of environment on yield L. Meckel et al. Pointed out in 1984 that grains
