先前的研究表明,小麦的耐铝性是由几个基因控制的显性性状.本试验用中度耐铝小麦“中国春”的一套非整倍体(双端体)进一步对其部分耐铝基因作了定位和定性研究.用经过修改的“Pulse”法(作者,1983)评价供试材料幼苗的耐铝性,衡量耐铝性的标准是将4日龄幼苗的根在3种铝浓度(37、56、74μM)的营养液中于25℃下培养24h,再使幼 Previous studies have shown that the aluminum tolerance of wheat is dominated by several genes, and in this experiment, a set of aneuploidy (two-terminal body) of moderately resistant wheat “Chinese Spring” The aluminum gene was mapped and characterized qualitatively.The standard of evaluating the aluminum tolerance of the seedlings of the tested materials by a modified “Pulse” method (Authors, 1983) (37,56,74μM) in nutrient solution at 25 ℃ for 24h, then make young
