摘要:
以玉米品种天紫23号、黄甜脆1号、白甜糯1号、早鲜黄甜脆幼苗为试验材料,研究干旱胁迫(停止浇水)、干旱胁迫时间(1、2、3、4、5 d)和解除干旱胁迫恢复生长后幼苗根系活力、叶片中总黄酮含量及自由水/束缚水比值的变化。结果表明,利用干旱胁迫处理4个品种玉米幼苗,根系活力、叶片中自由水/束缚水比值均随胁迫时间的延长而降低,叶片中的总黄酮含量均随胁迫时间的延长而上升;解除干旱胁迫恢复正常灌溉7 d后,根系活力、叶片中自由水/束缚水比值均上升,叶片中的总黄酮含量均下降,但这3个生理指标依然没恢复到正常灌溉水平。不同玉米品种在干旱胁迫和解除干旱胁迫复水时这3个生理指标的变化有一定的差异,对这3个生理指标进行综合分析,初步得出黄甜脆1号的抗旱性最强,其次是天紫23号,再次是早鲜黄甜脆,最差的是白甜糯1号。
