摘    要:目的:对夏枯草的繁育系统进行初步研究.方法:对夏枯草的开花特性进行观察,测定单花期内夏枯草的花粉活力和柱头可授性,测定夏枯草的花粉-胚珠比和杂交指数,进行套袋实验测定夏枯草结实率并检验种子品质.结果:夏枯草单花花期为1~2 d,主茎花序的花期为7 ~14 d;夏枯草的花粉胚珠比为1 046±148.26,繁育系统为兼性异交;杂交指数为2,繁育系统为兼性自交;套袋实验结果表明,在没有昆虫传粉的情况下,有较高的结实率,且所结种子有较高的发芽率.结论:夏枯草的繁育系统为自交、异交混合型,自交亲和.

关 键 词:夏枯草  繁育系统  套袋实验

Abstract:The research was conducted to study the breeding system of Prunella vulgaris L. Flowering dynamics was observed. Pollen viability, stigma receptivity, pollen-ovule ratio (P/O), out-crossing index (OCI) were measured. Bagging experiments were conducted. The results showed that the life span of one single flower was 1-2 days, the flowering span for the inflorescence of stalk was 7-14 days, the P/O was 1 046±148.26, the OCI was 2. Combined with results of bagging experiment, the breeding system of P. vulgaris L. was mixed with cross-polination and self pollination. In the absence of pollination insects, the pollination and fertilization can be accomplished with high seed setting rate, and the seeds have a relatively high germination rate.
Keywords:Prunella vulgaris  breeding system  bagging experiment
