壳聚糖胁迫对黄独带芽茎段生长发育的影响
Effects of chitosan on growth and development of Dioscorea bulbifeia L.
摘要
Abstract
[ Objective ] The effects of chitosan on growth and development of Dioscorea bulbifera L. Stems was studied to facilitate its commercial production. [Method]Single factor four-level group experiments were conducted, in which Dioscorea bulbifera L. Stems having single bud were cultured in MS+KT (2mg/L)+NAA(0.5mg/L) culture medium. The concentration of chitosan was 0 (CK), 0.5, 1.0 and 2.0 g/L. Various morphological indexes of Dioscorea bulbifeia L. Plantlets were observed regularly and data was analyzed statistically. [Result]Low concentration of chitosan enhanced the root and bud elongation to some extent in D. Bulbifeia and the effect was most significant at 0.5 g/L concentration of chitosan. High concentration of chitosan inhibited the growth of root and bud in D bulbifeia stems. At 1.0-2.0 g/L concentrations, the effects were more pronounced. Chitosan also reduced the leaf growth of D bulbifeia plants, and the effects were more pronounced at its 1.0 g/L concentration. [Conclusion]Low concentration of chitosan promoted the growth and development of D. Bulbifeia stems, while high concentration of chitosan showed contrary results.关键词
