- 摘要:
- 通过对红王子锦带花粉胚发育的细胞学观测与统计分析,对适宜红王子锦带花粉启动分裂的因子、适宜的花粉发育时期、适宜的接种时期以及适宜的培养基组合等条件进行了筛选。结果表明:适宜花粉启动分裂的因子为6-BA与MS基本培养基,6-BA的浓度越高,MS的浓度越低,出胚率越高;适宜花粉启动分裂的发育时期为四分体时期,出胚率为6.73%;适宜诱导的接种时期为6月;适宜的培养基组合为:1/3MS+6-BA2.0 mg·L-1+NAA1.0 mg·L-1+1%SUC。
- Abstract:
- Through cytologic observation and statistical analysis on the pollen embryos of Weigela florida cv.‘Red Prince’,the factors of suitable pollen starting division,suitable pollen development stage,suitable inoculating stage,suitable medium combination and other conditions were screened out.The results of showed that the main factors of suitable pollen starting division were 6-BA and MS basic medium,the higher level of 6-BA and the lower level of MS basic medium,the higher rate of embryos;The suitable development stage of pollen starting division was tetrad stage,the rate of embryos was 6.73%;The suitable inoculating stage induction was in June;The suitable inducing medium was 1/3MS+6-BA(2.0 mg·L-1)+NAA(1.0 mg·L-1)+1%SUC.
