| | Pollination regulates a syndrome of developmental events that contributes to flower senescence in high plant, for example, perianth senescence, flower pigmentation changes etc. In most species, the primary pollination events is accompanied by an increase in ethylene evolution within hours after pollination and before pollen germination. Some results suggest involvement of a primary and a secondary signal in the pollination response. They are both link to ethylene evolution and flower senescence. | | 高等植物中,授粉常调节与花衰老相关的许多发育过程,如花被的衰老、花色的变化等。在大多数种类中,授粉几小时之后、花粉萌发之前,乙烯的释放量便开始增加。在授粉反应过程中,有初级和次级两种授粉信号的参与,授粉对乙烯的生物合成及花衰老的调节都是通过这两种信号实现的。 | | 文摘来源 | |   |
