【摘要】 报道了熊蜂和苜蓿切叶蜂在网室内对大豆不育系授粉效果。结果表明,两种昆虫都是大豆不育系的有效传粉昆虫,用它们授粉后可使网室内大豆不育系的单株结荚数和单株粒数明显提高。释放熊蜂的不育系大豆平均单株结荚数和粒数分别为21.3个和43.1粒,释放苜蓿切叶蜂的不育系大豆平均单株结荚数和粒数分别为56.8个和128.2粒,苜蓿切叶蜂的授粉效果显著高于熊蜂。更多还原

【Abstract】 The results of using bumble bee and leaf-cutting bee to pollinate soybean male sterile plants in cages were reported in the paper. The results showed that both of them are effective pollinator of soybean male sterile strains. Numbers of pods and seed on a single plant were significantly increased by using these two pollinators. Average pods and seeds per plant were 21.3 and 43.1 respectively in cage releasing bumble bee, whereas in cage releasing alfalfa leaf-cutting bees it was 56.8 and 128.2 respectively. Therefore, alfalfa leaf-cutting bee is a better pollinator for pollinating soybean male sterile plants in cages.更多还原
