前言在花生有性杂交过程中,曾发现花生花柱头的长度长短不一,为了便于区分,我们根据其特点将花划分为长柱头(正常类型)、短柱头及隐藏柱头(以上两类为非正常类型)三种不同的类型。划分的标准是,在蓬莱地区7月底以前,下午4—7点钟的时间范围内,退下龙骨瓣后,能明显看到雌蕊柱头高于雄蕊的即为长柱头,与雄蕊相平或缩在雄蕊花药中间的为短柱头,柱头缩在花萼管内的为隐藏柱头.为了摸清由于柱头类型不同,对花生自然受精率的影响,曾于1977年进行过两次标花观察,7月11日标定非长柱头花(短柱头花与隐藏柱头花未分,下同)50朵,
Preface In peanut sexual hybridization process, we found that the length of peanut stigma head varies in length, in order to facilitate the distinction, we divided the flower into long stigma (normal type), short stigma and hidden stigma Normal type) three different types. Divided criteria is that in the Penglai region before the end of July, 4-7 o’clock in the afternoon, after the withdrawal of the keel flap, you can clearly see the pistil top of the stamens is the long stigma, with the stamens flat or shrink In the middle of the stamen anthers short stigma, stigma shrink in the calyx tube for the hidden stigma.In order to find out the different types of stigma on the natural fertilization rate of peanuts, had twice in 1977 observed flowers, July 11 Day calibration non-stigma flower (stigma flower and hidden stigma flower is not divided, the same below) 50,
