propagation system leading to formation of shoots from callus, roots, and plantlets was developed for Schizanthus hookeri Gill. (Solanaceae), an endemic Chilean plant. The genus Schizanthus is of particular interest due to the presence of several tropane alkaloids. So far, in vitro propagation of species of this genus has not been reported. Propagation of S. hookeri consisted of two phases, the first one for
为 Schizanthus hookeri Gill 开发了一种快速体外繁殖系统,导致愈伤组织、根和小植株形成芽。(茄科),智利特有植物。由于存在几种托烷生物碱,五味子属特别令人感兴趣。迄今为止,该属物种的体外繁殖尚未见报道。S. hookeri 的繁殖由两个阶段组成,第一个阶段是愈伤组织起始和枝条形成,第二个阶段是根发生和植株再生。在存在 2.69 microM NAA 和 2.22 microM BA 的情况下,单个愈伤组织在细胞生物量中迅速增加(60 天内从大约 50 毫克到大约 460 毫克/培养管 [25 x 130 毫米]),超过 10 个芽/愈伤组织外植体形成。从后者,大约。在没有促进根形成的生长调节剂的培养基中进行 90-110 天的芽次培养后形成 20 株小植株。从体外再生的小植株中获得了十种生物碱,从简单的吡咯烷衍生物到衍生自当归、tiglic、senecioic 或甲
