Quick and high-efficiency cephalotaxus hainanensis seed germinating and high-quality seedling breeding method

Abstract

The invention provides a quick and high-efficiency cephalotaxus hainanensis seed germinating and high-quality seedling breeding method which relates to a quick and high-efficiency plant seed germinating and high-quality seedling breeding method. The method comprises the following steps: (1) seed collection: collecting cephalotaxus hainanensis seeds to be matured or matured seeds; (2) preparation of seed germinating matrixes; (3) release of seed dormancy; (4) seed germination; and (5) acclimatization and transplantation. The invention can enhance the seed germinating bud ratio by more than 85%,the seedling viability exceeds 90%, the uniform high-quality cephalotaxus hainanensi seedlings can be produced, and the viability of seeds transplanted to fields can also exceed 90%; compared with the traditional method, the stocking time is shortened by about 2 / 3; the related facilities and processes of tissue culture and the like are not required, so the operation is convenient; the invention provides technical support for the quick propagation and restoration protection of rare or endangered species of cephalotaxus hainanensis and the development and the utilization of resources.

Description

technical field [0001] The invention relates to a method for rapid and efficient germination of plant seeds and cultivation of high-quality seedlings, in particular to a method for rapid and efficient germination and cultivation of high-quality seedlings of Torreya chinensis seeds. Background technique [0002] Cephalotaxus hainanensis Li (Cephalotaxus hainanensis Li) is a perennial tall evergreen tree. It is a rare tree species unique to my country, and its distribution range is extremely narrow, only found in Hainan, Guangdong, Yunnan and other local areas. Studies have shown that Torreya sinensis not only has the highest effective alkaloid content among the tricuspid family, but also has the most significant curative effect. It is currently recognized as one of the best anti-cancer tree species. In addition, this tree species has been repeatedly felled due to its excellent material quality, and its population is small. It is one of the most important rare and endangered ...

Problems solved by technology

In addition, there are also people who have studied the use of traditional tissue culture methods to propagate seedlings of Torreya hainanensis, but basically no seedlings can emerge, or the emergence rate is very low, and application and promotion cannot be carried out (Fu Wenying, Du Daolin, Fu Mujun.
