Problems solved by technology

[0003] The application number is 201310089480.9, which discloses a method for breaking the dormancy of the seeds of Taxus chinensis, which has the advantages of saving time, effectively and economically breaking the dormancy method, so as to solve the problems of deep dormancy, difficult germination and low germination rate. Seedling market circulation provides standards to ensure seed quality, which is of great significance to the breeding and cultivation of Taxus chinensis
Although this method effectively improves the germination rate of seeds, it does not significantly improve the survival rate of seedlings, and it can be seen from the operation method that the whole cycle of its treatment takes a very long time, and in addition adopts higher If the seeds are soaked in sulfuric acid with high concentration, if the treatment conditions are not properly controlled, the seed embryos of the seeds are likely to be damaged

Abstract

The invention discloses a Method for removing dormancy of seeds of Taxus chinensis var. mairei and increasing their survival rate, which comprises the steps: (1) selecting seeds; (2) storing with sand; (3) soaking the seeds; and (4) accelerating germination at a constant temperature. The dormancy of seeds is broken through sand storage, seed soaking, constant-temperature germination accelerating and other methods, the seed germination time is shortened, the seed germination rate and the seedling survival rate are increased, the method is scientific and safe, the time consumption is low, and the method has good market popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of yew planting, and in particular relates to a method for relieving dormancy of southern yew seeds and improving their survival rate. Background technique [0002] Southern yew ( Taxus chinensis var. mairei) belongs to the genus Taxus, which is a unique tree species in my country, mainly distributed in Anhui, Zhejiang, Fujian, Gansu, Yunnan and Shaanxi provinces. Its wood is fine and durable, and its quantity is rare. The bark contains paclitaxel, an anticancer drug ingredient. Now it has been felled and destroyed a lot, and it is in an endangered state. In 1999, it was listed as a first-class protected wild plant in my country. The dormancy period of southern yew is as long as 2-3 years under natural conditions, which is a typical comprehensive dormancy. The dormancy characteristics of yew seeds are mainly caused by post-ripening factors of embryos and endogenous substances in embryos. There is also r...
