本报告是我们对传统印度药用植物，没药，guggul类固醇来源的生殖生物学研究的一部分。实地检查显示，主要是大量孤立的女性个体和群体。只有一个雄花两性花同株和两个完全男性的植物记录。雌株无论有无花粉都能结籽。人工授粉实验和胚胎学研究首次证实了这种目前正受到过度开发威胁的植物存在非假配子无融合生殖、珠心多胚和胚乳自主形成等现象。(C)1996 Annals of Botany公司
The present report is a part of our study on the reproductive biology of a traditional Indian medicinal plant, Commiphora wightii, a source of guggul steroids. Field examination showed a predominantly large number of isolated and groups of female individuals. Only one andromonoecious and two exclusively male plants were recorded. Female plants set seed irrespective of the presence or absence of pollen. Hand-pollination experiments and embryological studies have confirmed the occurrence of non-pseudogamous apomixis, nucellar polyembryony and autonomous endosperm formation for the first time in this plant, which is presently threatened by over-exploitation.
