一九七三年四月至八月,杭州大学生物系植物生理与遗传教研组和浙江农业大学农学系杂优组,在黑龙江应用国产“乙烯利”(2—氯乙基磷酸)对几个小麦品种进行化学去雄试验,获得较好的效果。在植株孕穗期(雌蕊分化期到花粉粒发育期)用4000～6000ppm“乙烯利”喷雾处理,受药小麦花粉发育不正常,空秕畸形,无生活力;花丝变短,花药瘦小,花药不开裂或仅部分顶裂;麦穗套袋自交结实极少或完全不实,相对不育率85～100%,而雌蕊活性基本
From April to August 1973, Plant Physiology and Genetics Research Group of Biology Department of Hangzhou University and Zuo You Group of Agronomy Department of Zhejiang Agricultural University applied the domestic “ethephon” (2-chloroethyl phosphoric acid) to several wheat Varieties to chemical male test, get better results. In the booting stage (pistils to the pollen grain development period) with 4000 ~ 6000ppm “ethephon” spray treatment, the drug wheat pollen development is not normal, empty crooked deformity, no viability; filaments become shorter anthers thinner anthers do not Cracking or only part of the top cracking; wheat bagging self-infested very little or completely false, the relative infertility rate of 85 to 100%, while the basic pistil activity
