膜苞鸢尾花粉形态、活力与柱头可授性研究
Pollen Morphology, Viability and Stigma Receptivity of Iris scariosa Willd
摘要
Abstract
[Objective] To explore the dynamic variation rule with pollen viability and stigma receptivity of Iris scariosa Willd.,in order to provide a reliable basic data for sexual reproduction.[Method] Scanning electron microscope was used to observe pollen morphology,in vitro pollen germination and staining method were applied to test the pollen viability,and the stigma receptivity of different flowering period was evaluated with the benzidine-α-naphtho method,and the artificial-pollinate method was employed to test the best period of pollination.[Result] The pollen morphology of aperture is monocolpate,belonging to the distal single groove-quasi groove type,the outer wall of pollen surface had scattered columnar grains;The higher pollination held in the first flowering day and flowering after 4 h reached the highest peak,the stigma had receptivity from the first day to flowering after 32 h.[Conclusion] The pollen morpho-gy is a more primitive type,female flower matured before male,Pollen viability and stigma overlap.The day of flowering and the next day are the best time for artificial pollination.关键词
