Embodiment 1

[0018] 1 Materials and methods

[0019] 1.1 Materials

[0020] The tested tree species is wild yew (about 5 years old), which was collected and preserved in the field from 2011 to 2012 in Yueqiang Plantation Farm, Tianquan County, Ya'an City.

[0021] 1.2 Test method

[0022] 1.2.1 Preparation of cuttings and cutting beds

[0023] Select complete leaves, strong growth, full axillary buds and no pests and diseases, and trim the branches located on the periphery of the canopy of the mother tree to be cuttings with a length of 10-12 cm. Make a 45° incision at the base of the cuttings. The lower end of the yew is inserted into the substrate (about 5cm) without leaves, and the upper end and side branches all retain leaves. One day before cutting, use 80% wettable powder carbendazim 800 times to disinfect the cutting bed substrate.

[0024] 1.2.2 Test treatment

[0025] In mid-June, unlignified green branches, semi-lignified branches, and two-year-old hard branches (with side ...

Background technique [0002] Yew (Taxus chinensis Reld.) is an evergreen tree of the genus Taxus in the family Taxaceae, also known as yew and yew pine. It is an ancient tree species left over from Quaternary glaciers. "Living fossil" is listed as a rare tree species in the world because of its scarcity of resources. It is one of the eight most rare and endangered protected plants in China. The yew has a history of 2.5 million years. Taxus is a unisexual flower, dioecious, and cross-pollination. This biological characteristic leads to hindered fertilization and reduced seed number. Yew is a precious timber tree species in the world because of its fine wood material, toughness and durability; especially the unique anti-cancer ingredients in the yew plant - paclitaxel (Taxol) and its derivatives are internationally recognized as th...
