不同抗氧化剂和吸附剂对褐苞薯蓣组培褐化的影响
Effects of Different Antioxidants and Sorbents on Tissue Browning of Dioscorea persimilis
摘要
Abstract
The tissue cultured seedlings of Dioscorea persimilis cv.AnSha was used as experimental material to study the effects of four antioxi-dants(citric acid,ascorbic acid,phytic acid,silver nitrate)and two adsorbents(activated carbon(AC),Polyvinylpyrrolidone acid(PVP))on anti-browning,growth and multiplication of subculture propagators in tissue culture.The results showed that four antioxidants were not suit-able for use as anti-browning agents.The optimum dosage of PVP was 0.2 g/L in the two treatments of adsorbents,the explants browning in-dex were significantly decreased and the effective germination rate were increased.The activated carbon had no significant effect on decreasing browning index,but it mitigated the harm of browning,promoted the growth and effective rate of bud.关键词
