采用不同化学药物处理柱头,研究白菜型油菜与海甘蓝属间杂交花粉与柱头的相互作用,利用扫描电镜观察海甘蓝花粉在雅安黄油菜柱头上的黏合与萌发过程。结果表明:赤霉素在促进花粉萌发方面效果明显,在一定程度上能克服属间杂交不亲和;甘氨酸在促进花粉与柱头的黏合方面效果明显。
The chemical reactions of stigma were used to study the interaction of hybrid pollen and stigma between Brassica campestris and Brassica napus. The scanning electron microscopy was used to observe the sticking and germination process of Brassica campestris var. The results showed that gibberellin was effective in promoting pollen germination and could overcome incompatibility between genus hybrids to a certain degree. Glycine was effective in promoting the binding of pollen and stigma.
