Abstract

The present invention relates to a high-effective water soluble rooting powder for Mandiya taxus, belonging to a fast propagation technique for forest tree seed seedling. It uses alpha-naphthylacetic acid and sodium salt or potassium salt powder of indolylbuteric acid as main component, mixes them according to the ratio of 1:0.6-1.5 to obtain the invented rooting powder. In said powder material a proper quantity of rare earth microfertilizer also can be added. Besides, said invention also provides the application method and concrete steps of said rooting powder.

Description

technical field [0001] The invention belongs to the rapid propagation technology of forest tree seedlings, in particular to high-efficiency water-soluble rooting powder for cutting propagation of Taxus chinensis. Background technique [0002] Since wani et al. extracted paclitaxel from the bark of Taxus brevifolia Nutt. and found that it has anticancer effects, researchers have successively discovered its unique anticancer mechanism and can treat various diseases. cancer. [0003] Paclitaxel (Taxol) is a diterpene compound isolated from the bark of Pacific yew (Taxus brevifolia) in 1971. It is a natural product with a unique anti-cancer mechanism, which can induce and promote tubulin binding, thereby preventing cancer Cell proliferation, has cytotoxic effect on human ovarian cancer, breast cancer, cervical cancer, lung cancer, CNS cancer, melanoma, liver cancer and leukemia cell lines, and is the hottest anticancer drug after doxorubicin and ci...
