Growth traits and triptolide accumulation of Tripterygium wilfordii callus
摘要
Abstract
This study investigated the effects of different explants, culture media and pH on induction of Tripterygium wilfordii callus. And then physiological and biochemical properties and triptolide accumulation in the callus were further analyzed. The results indicated that, to induce T. wilfordii callus, the best explants were tender leaves of tissue culture seedlings, the most suitable medium was MS, and the optimal pH values ranged from 5.8 to 6.1. The activities of SOD and POD both reached the maximum at the middle stage (4th week) and the end (8th week) of the callus growth period, when MDA content and PAL activity showed relatively low values. At the stationary growth phase, SOD and POD had low activities, while MDA content and PAL activity were high. As to triptolide content in the callus of different explants, the root callus and the leaf callus shared similar levels, significantly higher than the stem callus. The callus produced higher triptolide amount at the latter stage ( 6th to 8th week) of the growth period.关键词
