| 摘 要： | 为明确柴胡种子的生物学性状,探讨柴胡种子发芽进程的变化规律,测定了l2种柴胡种子的大小、千粒重、生活力、发芽率,并对其千粒重、生活力、发芽率3项指标进行差异显著性分析和相关性分析。结果表明,12种柴胡种子的3项指标均达到显著水平,发芽率和生活力的相关系数最大,为0.86且达到极显著水平,品种间的发芽率差别很大,发芽进程也不相同,‘中柴一号’等高发芽率品种的发芽起始日早,发芽延续时间长,且有发芽高峰期;‘左权柴胡’等低发芽率品种发芽起始日晚,发芽延续时间短且日发芽数较恒定,无发芽高峰出现。筛选出的高发芽率品种,对柴胡良种选育和实际生产都有重要的指导意义。

| Abstract: | In order to study the biological characteristics of Bupleurum chinense seeds and discuss the variation rules of seed germination,the seed size,1000-grain weight,seed viability,germination rate of 12 Bupleurum chinense cultivars were determined.Significant difference analysis and correlation analysis on 1000-grain weight,seed viability and germination rate were conducted.It was found that correlations among the three indices of each cultivar reached a significant level and the correlation coefficient between... |
