谷子种子愈伤组织的诱导与植株再生
Effects of different kinds of hormones on the callus induction and plant regeneration of millet seeds
摘要
Abstract
[Objective]Effects of varioustypes of hormones at different concentrations on callus induction and plant regeneration of Jingu 21 seedlings were investigated.Present study was aimed to determine the optimal hormone ratio for better callus in-duction and differentiation,and to establish a stable millet regeneration system with high efficiency.[Methods]The matured seeds of Jingu 21 millet were employed as explant material,and effects of different types of hormones at different concentra-tions on callus induction and plant regeneration of Jingu 21 were studied.[Results]By adding 2,4-D to MS medium,the callus induction rate was enhanced and better than that of NAA,and the quality of callus was improved by adding a certain concen-tration of 6-BA to the medium.When the concentration of 4-D and 6-BA were 2.0 mg·L-1 and 0.2 mg·L-1 ,respectively,the callus induction rate reached the highest peak at 92.86%.In the process of callus differentiation,the effect of adding 6-BA was significantly better than that of ZT,with the highest callus differentiation rate (1 3.33%)occurred at the concentration of 6-BA at 1-0 mg·L-1 .In addition,transferring millet seedlings to MS medium induced root development.[Conclusion]The opti-mal medium for inducing callus was MS mixed with 2.0 mg·L-1 2,4-D and 0.2 mg·L-1 6-BA,and the best differentiation medium combination was MS plus 1.0 mg·L-1 6-BA.关键词
