概要 The efficient plant regeneration protocols were developed for Doritaenopsis Taisuco Ladylip through callus culture and somatic embryogenesis. The embryogenic calli were cultured on half strength Muras...hige and Skoog (MS) medium supplemented with 0.5 mg·L^<-1> thidiazuron, 2.5 mg·L^<-1> 2,4–dichlorophenoxyacetic acid, 30 g·L^<-1> sucrose and 3 g·L^<-1> Gelrite for proliferation. Basal salts, carbohydrate of medium obviously affected the somatic embryogenesis of callus. The highest frequency of somatic embryogenesis was obtained when embryogenic calli were cultured on half strength MS medium containing 20 g·L^<-1> maltose or 10 g·L^<-1> trehalose. The protocorm–like bodies well developed into plantlets after changing the basal salts to Hyponex,and carbohydrate to sucrose. The histological processing of somatic embryogenesis from callus was observed with light microscopy, and somatic embryo was clearly origin from single cell.続きを見る
