摘 要 ：目的:了解影响柴胡种子萌发的主要因素。方法:取不同成熟度柴胡种子浸泡、挑破或去除种皮后,在光照培养箱中做发芽试验。结果:柴胡不同级别花序发育时期差异较大,生产上收获的种子成熟度参差不齐,果Ⅰ～果Ⅲ期种子基本没有发芽力,果Ⅳ～Ⅶ期种子发芽率有显著差异;柴胡种皮对种子水分和气体吸收没有障碍,但去除种皮显著提高了种子发芽率,而去皮后浸泡48 h不能进一步提高发芽率。结论:种子成熟度及种皮内含有的发芽抑制物是影响柴胡种子萌发的重要因素。

Abstract:Objective: To investigate the factors influencing the seed germination of Bupleurum chinense and B. falcatum. Method: The seeds of different maturity, and the seeds whose coat were removed or nicked before clipping in water, were germinated in a light growth chamber. Result: The different inflorescence level represents different development period. Seeds harvested from cultivation have different maturity. The germination rate of the seeds in period I to IE was nearly zero, and it was significant different from period Ⅳ to Ⅵ. The seed coat is not an obstacle for water absorption or gas exchange, but its removal led to significant increase of seed germination rate. However, to dip the seeds without coat into water for 48h had no more effect on germination. Conclusion: The seed maturity and germination inhibitors in seed coat are two important factor influencing seed germination in B. chinense and B. falcatum .
