通过对78份普通丝瓜品种30节内的雄、雌花蕾着生状况进行调查,分析了无性节、纯雄节、纯雌节和双性节(同时存在雌雄花蕾)的分布规律。结果表明:普通丝瓜的性别分化比较复杂。无性节一般分布在起始几节,呈现连续或不连续分布,少量品种在高节位还有零星分布;双性节中雌花和雄花有11种组合方式,以多雄+单雌节最常见,在所有丝瓜材料中均有出现;雄花从个体(枚数)存在状态看,有单枚和多枚(又叫总状花序)之分,雄花分布在纯雄节和双性节之中,雄花在纯雄节中存在6种表现形式;早熟材料的有雄节(包括纯雄节和雌、雄节)有24.1节,中熟材料的有雄节有23.6节,晚熟材料的有雄节有21.3节,且熟性越早有雄节数越多;雌花在纯雌节中有4种表现形式,以单雌形式存在最普遍;早熟材料的有雌节(包括纯雌节和双性节)有23节,中熟材料的有雌节有18.7节,晚熟材料的有雌节有13.55节;无性节、纯雄节、纯雌节和双性节的数量与品种来源地、果形、植株长势和叶色均未表现出趋势性差异。
The distribution of male and female buds in 30 sections of common sponge gourd varieties was investigated. The distribution of asexual section, pure male section, pure female section and bisexual section (male and female buds) were analyzed. The results showed that the sex differentiation of common loofah is more complicated. Asexual sections are generally distributed in the first few sections, showing a continuous or discontinuous distribution, a small number of varieties in the high node there sporadic distribution; bisexual section of female flowers and male flowers have 11 combinations, with more male + single female most common , In all loofah materials have appeared; male flowers from the individual (number) the existence of the state, there are single and multiple pieces (also known as raceme) of the points, male flowers are distributed in pure male and bisexual sections, male flowers There are 6 kinds of manifestations in the pure male section; male section (including pure male and female, male section) of early maturing material has 24.1 sections, male section of medium mature section has 23.6 sections, late mature material has male section 21.3, and the sooner the maturity, the more the number of male and female nodes; the female flower has 4 kinds of manifestations in the pure female section, and is the most common in the form of single female; the female section (including pure female section and bisexual section ) Had 23 knots, medium knitted material had 18.7 knots, late-matured material had 13.55 knots; asexual, pure male, female and bisexual sections of the number of sources and varieties, fruit shape, There was no trend difference between plant growth and leaf color.
