白芍原植物的传粉特性研究

研究药用白芍的传粉特性,为药用白芍的资源保护和优良品种选育提供科学依据。采取11种不同的处理方式,比较不同授粉方式的结实率和结实质量。芍药的自然结实率低;芍药的异株异花传粉可提高芍药的结实率达3倍,自然生长的花人工给予授粉结实率可提高近4倍;芍药的同株自花直接套袋、同株自花人工授粉和同株异花人工授粉的结实率均不高,分别为0.17%、0.84%、1.16%;去雄和去花冠处理结果表明芍药以异花传粉为主,同时花冠在传粉结实中也起到一定的作用。芍药具有微弱的自交性,芍药以异株异花授粉为主;异株异花授粉,可提高芍药的结实率;同时对芍药的结实率低的原因给以初步分析整理。

Study on the Pollination Characteristic of Chinese Medicine" Radix Paeoniae Alba"

To provide a scientific basis for the protection of medicinal peony resources and good breeding by studying the pollination characteristic of Chinese Medicine ＂ Radix Paeoniae Alba.To compare different ways to deal with the average fructication rate and seed quality by 11 different pollination methods.Peony is kind of cross-pollination with weak capability of selfing;Paeonia of cross-pollination coming from different plants can increase the peony fructication rate of 3 times,the natural growth of flowers given to pollinate fructication rate can increase nearly 4 times;The average fruction rate of no-pollination is 0.17%,the average fructication rate of cross pollination in one flower is 0.84%,and The average fructication rate of cross pollination in one plant is 1.16%;Emasculation and Corolla to deal with the results of peony show to the main cross-pollination,at the same time in the Corolla pollination also play a strong role.Peony is kind of cross-pollination with weak capability of selfing,but no apomixes was found;Paeonia of cross-pollination coming from different plants can increase the peony fructication rate;at the same time,the reasons of Peony low rate give a preliminary analysis.
