摘 要 ：采用耐低钾的玉米自交系T和一般的自交系C，以4水平钾浓度的水培方法进行对照研究。结果表明，在高钾情况下，两自交系干重几乎相同，随着钾浓度的下降，自交系T的干重明显大于自交系C:;随钾浓度的下降，自交系C缺钾症状加重，而自交系T除一K处理外均无缺钾症状;缺乏钾素。自交系C的主根伸长增加及冠/根比下降程度比自交系T明

Abstract:Two inbreds of Zea mays，T being is tolerant to K+ deficiency and C being sensitve to K+ deficiency，were grown in the presence of different concentrations of K+.Several parameters were compared between two inbreds and characteristic differences in terms of K+ utilization were observed. The dry weig
