半夏花器特性及提高结实率研究

Studies on the Floral Organ Property and Increasing Seed-Setting Rate of Pinellia ternata

摘要: 在观察研究半夏花器形成及构造特点后,发现半夏为雌雄同株,但不同时期成熟的异花授粉植物,如改善栽培管理条件,辅之人工授粉便能提高结实率0.5～4.7倍,这对于提高半夏繁殖率、建立种子基地、加速半夏生产有实际意义。

Abstract: The inflorescence of medicinal plant Pinellia ternata (Thunb.) Breit occurs when its tuber reachs 0.5g. With continuous adding to the tuber weight, the number of inflorescences and rate of seed-setting increases. However, the tuber beingover 5 g, it shows
