Abstract
A study of the effects of different steroids on germination and tube growth of tobacco pollen (Nicotiana tabacum L. cv Petit Havana SR1) matured in vitro is presented. Application of the mammalian steroid sex hormones (testosterone, progesterone, and estradiol) resulted in a stimulation of pollen germination and tube elongation. The presence of both steroids and flavonols in the germination medium strongly enhanced the growth of tobacco male gametophytes.
摘要
本文介绍了一项关于不同类固醇对体外成熟的烟草花粉（烟草品种 Petit Havana SR1）萌发和花粉管生长影响的研究。应用哺乳动物类固醇性激素（睾酮、孕酮和雌二醇）可刺激花粉萌发和花粉管伸长。萌发培养基中同时存在类固醇和黄酮醇可显著促进烟草雄配子体的生长。
