Embodiment 1

[0030] A hybrid breeding method for the use of an accelerator for Taxus chinensis, comprising the steps of:

[0031] (1) Pollen collection: Determine the male and female plants of Taxus wallichiana var. mairei and Taxus x media, and investigate the specific time of flowering. The results showed that the first flowering period of male flowers of Taxus chinensis was more than 10 days earlier than that of Taxus mandiensis, and the first flowering period of female flowers was basically the same. . In late February, the pollen of the male plants of Taxus mandiensis was collected, dried naturally, and after removing impurities, it was placed in an EP tube and refrigerated at 4°C for later use, and kept dry.

[0032] (2) Pollination: From March 1, observe the female flowers spitting water on the female plants of Taxus chinensis and Mandia yew, and take out the stored pollen the next day after finding that the female flowers have entered the water-spitting period, and leave them at r...

Embodiment 2

[0049] The genetic breeding method of the promoter for Taxus mandiensis, including the following steps:

[0050] (1) Pollen collection: Determine the male and female plants of Taxus wallichiana var. mairei and Taxus x media, and investigate the specific time of flowering. The results showed that the first flowering period of male flowers of Taxus chinensis was more than 10 days earlier than that of Taxus mandiensis, and the first flowering period of female flowers was basically the same. . In mid-February, the pollen of the male plant of Taxus chinensis was collected, and in late February, the pollen of the male plant of Taxus Mandia was collected, dried naturally, and after removing impurities, it was placed in an EP tube for refrigeration at 4°C, and kept dry.

[0051] (2) Pollination: From March 1, observe the female flowers spitting water on the female plants of Taxus chinensis and Mandia yew, and take out the stored pollen the next day after finding that the female flowe...

Abstract

The invention discloses accelerant for root growth of taxus chinensis and a method for applying the accelerant to crossbreeding. The accelerant comprises candida yeast fermentation liquid, bacillus licheniformis fermention liquid, cellulomonas flavigena fermentation liquid, dung producing alkali coli fermention liquid, gibberellins, activated carbon and dipotassium phosphate. The accelerant can push taxus chinensis tissue culture seedlings to root rapidly and raise the survival rate, and the accelerant has significant and profound significance to deep development and wide applciaiton of taxus plant resources and wide is application prospect.

Description

technical field [0001] The invention relates to the technical field of agriculture and forestry, in particular to a promoter for the growth of the roots of Taxus chinensis and a method for cross-breeding thereof. Background technique [0002] Taxus, also known as yew, is a precious tree species under national first-class protection, and natural forest resources have been exhausted. Taxus is an evergreen tree with straight trunk and beautiful tree appearance. The seeds are red when mature, and the fake skin is bright and dazzling. It is an excellent bonsai and green tree species. Taxus wood is sturdy and durable, with beautiful texture. Its roots and stems are high-grade carving materials and belong to special forest materials. Its roots, stems, bark and leaves contain paclitaxel, which is a recognized cancer drug in the world today. It has obvious effects on the prevention and treatment of diabetes and cardiovascular diseases, and is an expensive medicinal forest. In recen...
