摘要:

为探索去雄时间和携带顶叶数对鲜食甜糯玉米温科糯1号穗部性状的影响,本研究设置4个去雄处理(T1:5月23日去雄,携带3.30片顶叶;T2:5月26日去雄,携带2.10片顶叶;T3:5月29日抽雄期当天去雄,携带0.80片顶叶;T4:6月2日去雄,携带0片顶叶),并以不去雄处理作为对照(CK),于采收期统计各处理的穗部性状。结果表明,所有去雄处理的穗长、秃尖长、行粒数、鲜穗重和净穗重均大于对照,但穗粗小于对照,这可能与温科糯1号的穗轴无限生长的特性有关。其中,T3处理的鲜穗重和净穗重均高于其他处理,说明温科糯1号在抽雄期当天去雄并携带0.80片顶叶的增产效果最好。

Abstract:

To investigate the effects of detasseling time and the number of top leaves removed on ear traits of the fresh edible sweet-waxy maize cultivar Wenkenuo 1, four detasseling treatments were set up: T1, detasseling on May 23rd, 3.30 top leaves removed; T2, detasseling on May 26th, 2.10 top leaves removed; T3, detasseling on the day of tasseling (May 29), 0.80 top leaves removed; T4, detasseling on June 2nd, 0 top leaves removed. A non-detasseled treatment served as the control. Ear traits were investigated and analyzed at harvest. The results showed that ear length, bald tip length, kernel number per row, fresh ear weight, and net ear weight in all detasseling treatments were greater than those in the control, while ear diameter was smaller. This may be related to the indeterminate growth characteristics of the ear axis in Wenkenuo 1. Among the treatments, T3 exhibited the highest fresh ear weight and net ear weight, indicating that detasseling at the tasseling stage with 0.80 top leaves removed achieved the best yield-enhancement effect for Wenkenuo 1.
