为提高大豆有性杂交成活率和真杂种率,我们对影响大豆杂交授粉的几个因素进行了试验,报道如下。一、调解花期大豆人工授粉能否成功,首先取决于花期是否相遇。在杂交亲本的生育期差异较大时,发生花期不遇。解决的办法是错期播种、遮光处理或两者同时使用。
In order to improve the rate of sexual crossbreeding and the true population of soybean, we tested the impact of several factors on soybean pollination, reported as follows. First, the mediation of flowering soybean artificial pollination success, first of all depends on whether the flowering meet. When the parents of hybrids have big difference in their growth period, the flowering period will not happen. The solution is to plant the wrong seeds, shading, or both.
