摘要

一种植物类固醇激素，油菜素内酯，当施用于去势花蕾的柱头时，可诱导单性生殖单倍体种子产生。拟南芥(Arabidopsis thaliana)和芥菜(Brassica juncea)获得的单倍体种子发育为稳定的单倍体植株，而第三种植物Tradescantia paludosa的单倍体种子在萌发后很快变成单倍体-二倍体混合倍体，然后变成二倍体。

Induction of parthenogenetic haploid plants with brassinolide

A plant steroid hormone, brassinolide, was found to induce parthenogenetic haploid seed generation when applied to the stigmas of the castrated flower buds. In the two species examined, Arabidopsis thaliana and Brassica juncea, haploid seeds were obtained which developed to stable haploid plants, but in the third species, Tradescantia paludosa, haploid seeds when germinated soon became haplo-diplo mixoploid and then diploid.
