2010~2011和2011~2012年小麦生长季,在山东省兖州市小孟镇史王村进行大田试验,供试材料为高产小麦品种济麦22。2010~2011生长季,设置0~20cm(D1)、0~40cm(D2)、0~60cm(D3)和0~140cm(D4)4个测墒补灌土层深度,每个土层深度设7个补灌水平,分别为W1(拔节期目标土壤相对含水量为60%,开花期为60%),W2(拔节期为65%,开花期为65%),W3(拔节期为70%,开花期为70%),W4(拔节期为75%,开花期为75%),W5(拔节期为80%,开花期

本文以不耐荫型玉米杂交种豫玉22(YY22)耐荫型玉米杂交种郑单958(ZD958)为材料,以盆栽方式研究了弱光胁迫对不同基因型玉米果穗生长发育的影响,结果表明:1、弱光胁迫延缓了雌雄穗的生长发育。弱光胁迫使抽雄、吐丝和盛花期延迟,花期和雌雄间隔期延长。弱光胁迫下不耐荫型玉米花粉量比对照显著增加,耐荫型玉米花粉量与对照差异较小;不耐荫型玉米花粉表面网纹在弱光胁迫下变粗且间隙增大,花粉萌发孔及其附近
