甘草花粉超微鉴定及花粉活力、柱头可受性荧光显微镜观察

对甘草的有性生殖特性进行了研究,利用扫描电子显微镜对乌拉尔甘草、光果甘草和胀果甘草花粉的超微结构进行观察,利用荧光显微镜确定乌拉尔甘草的授粉方式、花粉生活力和柱头活性以及授粉后受精时间。结果表明,花粉超微结构为甘草的鉴别提供了一定的形态学依据;甘草的授粉方式属于闭花受精;花粉生活力在每天12∶00时最强,去雄后超过4d的柱头已经不具备接受花粉的能力;对授粉后不同时间的雌蕊进行研究得出授粉后6h花粉管进入胚珠进行受精。...

The ultrastructure of the pollen in the Glycyrrhiza uralensis Fisch.,G.glabra L.and G.inflata Batal.were observed by the scanning electron microscope（SEM）.Pollination way,pollen viability stigma activity and the fertilization time ascertainment after pollination were observed by the fluorescence microscope.The results showed that the study on the ultrastructure of pollen offered certain morphology basis for the discrimination of the liquorice.The pollination way of the liquorice was cleistogamy.The pollen viability was
