在药用植物引种栽培中,某些植物的种子萌发困难,往往是种子繁殖上存在的重大问题。黄连(Coptis chinesis Franch)是我国重要的药用植物之一。它的种子在采收以后,不能立即萌发,尚需要一个相当长的休眠期。如何破除休眠,提早萌发,是解决种子繁殖和缩短生长年限的措施之一。谭炳杰等的研究曾指出,赤霉素和生长素并用时,在室温下就可打破黄连种子的休眠。但要彻底解决这一问题,首先还必须弄清楚休眠的原因以及萌发所需的条件等。掌握种子本身的要求和萌发的规律以后,就必然可以为破除种子休眠提供理论根据。无疑地,解决这一问题是具有理论和实践上的意义的。
In the introduction and cultivation of medicinal plants, the germination of certain plants is difficult, which is often a major problem in seed reproduction. Coptis chinesis franch is one of the important medicinal plants in China. After its seeds are harvested, they cannot germinate immediately. They still need a long period of dormancy. How to break the dormancy and germinate early is one of the measures to solve the problem of seed reproduction and shorten the growth period. Tan Bingjie et al.’s research has pointed out that when gibberellin and auxin are used together, the dormancy of Coptis chinensis seeds can be broken at room temperature. However, to completely solve this problem, we must first understand the reasons for dormancy and the conditions needed for germination. After mastering the seed’s own requirements and the laws of germination, it will inevitably provide a theoretical basis for breaking the seed dormancy. Undoubtedly, solving this problem is of theoretical and practical significance.
