Abstract

A new micropropagation system for Lycium barbarum (L.) was developed using root explants as starting material. Callus can be produced from root explants on Murashige and Skoog (MS) medium containing 0.2 mg dm-3 2,4-dichlorophenoxyacetic acid. After three subcultures on the same medium, callus was then transferred onto the MS medium supplemented with 500 mg dm-3 lactalbumin hydrolysate to induce somatic embryogenesis (SE). After 20 d, about 60 somatic embryos per 0.25 g(f.m.) of embryogenic callus were obtained but only about 10 % of embryos converted into plantlets. After acclimated in the greenhouse, all of the randomly selected plantlets had survived and were similar phenotypically to zygotic seedlings. In addition, the effects of irradiance, photoperiod, growth regulators, explant age and cold treatment on SE of root-derived callus were evaluated.
