Chinese yew breeding method for improving paclitaxel content of Chinese yew

Abstract

The invention discloses a Chinese yew breeding method for improving paclitaxel content of a Chinese yew. The method comprises the following steps: 1) breeding seeds: each year from March to April, in desolate mountain, pulling fresh and alive and robustly growing moso bamboo to cover a Chinese yew, applying UV-irradiation, using a bee pollination copulation method to breed a natural wild millennium Chinese yew seed tree, after taking care of the tree for more than ten months in the desolate mountain, the fruits of the redwood tree fully absorbing various kinds of benefical natural elements and nutrients of air and the moso bamboo, through a pollen period, a green fruit period, fruits being mature in a red bright period, the mature period being in the middle of Chinese calendar October, harvesting in autumn to obtain seeds of mature Chinese yew; 2) cellaring the seeds, including performing pre-treatment on the seeds, and cellaring to dormancy for three years; 3) growing, including screening full seeds to directly seeding in seedling furrow land, and the seeds naturally sprouting to breed a Chinese yew sapling. The method solves problems in the prior art that Chinese yew resources are wasted, and original values of a Chinese yew species are improved.

Description

Technical field [0001] The invention relates to a yew propagation method, in particular to a yew propagation method for increasing the content of yew paclitaxel, and belongs to the technical field of plant propagation and cultivation. Background technique [0002] Taxus chinensis is a kind of miraculous tree species that was once brought into space by Shenzhou 4. Its shadow can be found in the White House, Buckingham Palace, United Nations Headquarters in the United States. It is the yew known as a healthy tree.
