Embodiment 1

[0018] A method for releasing the dormancy of silver magpie tree seeds and improving the survival rate of seedlings, specifically as follows:

[0019] In the fruit ripening season of the silver magpie tree, the fruit with large fruit, bright color and full grain is collected from the mother plant with good fruit performance and no pests and diseases. After a period of drying, the shriveled peel is removed, and the fruit with full grain, Glossy seeds are for subsequent use; Then spread the collected seeds in a ventilated and cool place, dry in the shade for 15 days, wash the collected seeds with warm water 2 times, and then use 7% KH 2 PO 4 Soak the solution for 7 hours, then soak in 0.1% potassium permanganate solution for 4 hours, then soak the seeds in 50% sodium chlorate 50 times solution for 3 hours, and then wash the seeds with sterile water 2 times to obtain disinfection. Seed;

Abstract

The invention discloses a method for removing the seed dormancy of tapiscia sinensis oliv and improving the seedling survival rate. The method is mainly realized by the following steps: selection of seeds, disinfection of seeds, ultrasonication, hormone and heterotherm stratification, seed seedling and the like. By means of technology of growth regulator control, heterotherm treatment and the like for breaking the seed dormancy, with the adoption of the growth regulator with appropriate concentration and an appropriate heterotherm treatment medium, the seed germination time of tapiscia sinensis oliv is greatly shortened. Furthermore, with the adoption of appropriate temperature and light treatment as well as an appropriate seedling medium, the survival rate of a nursery-grown plant is further high.

Description

technical field [0001] The invention relates to a method for releasing seed dormancy and improving seedling survival rate, in particular to a method for releasing silver magpie seed dormancy and improving seedling survival rate. Background technique [0002] Silver magpie tree, also known as gall pepper tree, is scattered in the Yangtze River Basin of my country. Due to the long interval between fruiting, weak natural regeneration ability, and natural forest trees being cut down, the number of plants is decreasing day by day. Silver magpie tree is a unique ancient tree species in the subtropical flora of China. It is a third-level protected plant in China and has certain scientific value for the study of China. The wood is light and soft, straight in texture, smooth in planing, easy to rework, and can be used as furniture and panels. It has lush branches and leaves, beautiful tree shape, bright-colored fruit, light wood material and beautiful texture. It is not only an exc...
