前言我们在从事豆类种子吸胀冷害的研究中,发现不同的大豆品种对吸胀冷害的反应不同,而且不同的大豆品种对聚乙二醇即PEG的“引发”效果也各异,可见品种的不同,膜的修补及膜的构型也有所不同。例如“黑河3号”、“合丰24”、“合交706”这些品种在吸胀过程中对低温很敏感,很容易受害,而“黑农26”这个品种在吸胀过程中对低温有很强的 Preface We are engaged in the research on the chilling injury of legume seeds, we found that the response of different soybean varieties to the chilling injury is different, and different soybean varieties have different effects on the initiation of polyethylene glycol (PEG) The membrane repair and membrane configuration is also different. For example, “Heihe No.3”, “Hefeng 24” and “Jiaozuo 706” are sensitive to low temperature in the process of imbibition, and are easily victimized. However, the variety “Heinong 26” Very strong
