摘要:
【目的】研究水分胁迫对不同棉花品种生长发育的影响,筛选出抗旱种质资源,为棉花抗旱新品种选育提供依据。【方法】以11份陆地棉品种(系)为材料,设置正常灌水(3 600 m3/hm2)与水分胁迫(1 800 m3/hm2)2个处理,研究陆地棉在水分胁迫与正常灌水下生育进程、形态指标、干物质积累、抗氧化酶活性变化以及产量构成因素的差异。【结果】参试材料生育期缩短1~5 d;棉花生育期缺水抑制了棉花植株的生长,果枝量减少、单株铃数降低;水分胁迫下参试材料棉株干物质积累量在蕾期、花铃期、絮期分别下降0.70 、5.68、2.18 g/株。有效铃数减少0.89g/株,单铃重平均下降0.23 g,籽棉减产幅度达到1.93%~37.14%。水分胁迫下11个参试品种(系)的抗氧化酶活性发生变化,3个参试品种(系)的SOD、POD、CAT活性均升高。【结论】参试材料9号、2号在水分胁迫下生长发育情况较好,棉花减产不显著,为抗旱性较好的棉花品种。
