欧榛种子休眠与萌发研究进展

Research Advance on Seed Dormancy and Germination of Corylus avellana

欧榛是重要的坚果树种之一,但由于其种子休眠程度深,尤其是贮藏后的次生休眠问题,导致了破除休眠所需时间长,苗木生产中萌发率低,出苗不整齐,制约了欧榛的应用。该研究综述了破除欧榛种子休眠的方法、欧榛种子休眠的原因、以及在NIKOLAEVA和BASKIN系统下欧榛种子休眠所属的休眠类型,并根据目前研究的不足探讨了以后的研究方向,以期为欧榛种子的研究、推广、应用提供理论指导。

Corylus avellanais was one of the excellent species of nut.But due to the high seed dormancy and the secondary dormancy during the storage,which caused the long time of breaking seed dormancy,low germination rate and inconsistent seedling.It restricted the use of C.Avellana.The study researched reason of C.Avellana seed dormancy,the methods of breaking C.Avellana seed dormancy,the type of seed dormancy in Nikolaeva and Baskin system,and the problem that could be studied in the future research.In order to provide theoretical guidance on studying,popularizing and applying in C.avellanaseed.
