Abstract:

以紫花苜蓿为材料,探讨了铝对根伸长、根毛变形、结瘤和苜蓿根瘤菌(Rhizobiummeliloti)生长的影响,旨在阐明豆科作物共生结瘤的初期铝毒害的机制。结果显示,在3、6、9!mol·L-1AlCl3处理24h后,初生根相对伸长率分别为对照(不加铝)的78.4%、43.1%和26.8%,根瘤菌的活菌数分别比对照减少了47.37%、63.16%和84.21%;在不接种根瘤菌而添加结瘤因子的情况下,苜蓿结瘤初期根毛对结瘤信号的应答反应-根毛变形的比率降低了44.59%、71.43%和80.09%,而在缺乏结瘤因子的情况下,铝对根毛变形无显著的影响;在接种根瘤菌条件下,用2、3、4、5、6!mol·L-1Al处理48h后,根毛变形率分别减少了24.54%、33.18%、51.82%、63.05%和67.86%。这些结果说明,在铝胁迫下根毛变形受阻可能是铝抑制结瘤信号传递的结果。
