有性杂交是培育紫云英新品种的重要途径之一。了解紫云英开花习性并掌握杂交技术,则是杂交成功的关键。自1957年以来,我们在进行紫云英地方品种整理和杂交育种工作的同时,于杭州对紫云英开花习性和杂交技术进行过一些探讨。现将有关资料整理如下,以供参考。紫云英的开花生物学1.开花的顺序和时间:紫云英的花一般枝主茎上先开,接着是基部第一对分枝的主是,然后再按分枝发生的早迟,依序逐渐开
Sexual hybridization is one of the important ways to cultivate new varieties of Astragalus sinicus. Understanding the flowering habits of Swallows and mastering hybridization techniques are the keys to successful hybridization. Since 1957, we have conducted some discussions on the flowering habits and hybridization techniques of Astragalus mongolicus in Hangzhou while carrying out the work of arranging and breeding the local varieties of Astragalus sinicus. The relevant information is now organized as follows for reference. Asclepiadaceae flowering biology 1 flowering order and time: Asclepiadaceae flower main branches of the main stem first open, followed by the first base of the main branch is the branch, and then according to branch occurred early, according to Gradually open the order
