油用芍药的传粉特性及繁育系统研究

Studies on Pollination Characteristics and Breeding System of Paeonia lactiflora Pall

摘要: 芍药是我国重要的一类观赏和药用花卉，在油用方面的价值也越来越重要。本研究对当前主要的一类油用芍药资源——杭白芍的传粉特征和繁育系统进行了相关研究。结果表明，油用芍药存在一定程度的自交，但其授粉需要昆虫的辅助，以异交为主，属兼性自交的植物；但是存在自交衰退的现象。本研究可为油用芍药的生产及育种实践提供重要的理论支持。

Abstract: Herbaceous peony is the traditional Chinese medicinal and ornamental specie as well as a kind of new oil crops in China. Here, we focused and analyzed the pollination characteristics and breeding system in Paeonia lactiflora Pall, which can be as actual or potential value specie. The results showed that there existed self-compatible, but mainly out-crossing in Paeonia lactiflora Pall. And we found that their pollination processes require pollinators, such as wind and insects. Thus, our studies provide important theoretical support for planting this kind of herbaceous peony in future.
