Cratevareligiosa G. Forster root cutting seedling culture method

Abstract

The invention provides a cratevareligiosa G. Forster root cutting seedling culture method which includes the steps: (1) selecting seminal roots according to germination ability and richness of seminalroot sources; (2) cutting and disinfecting the seminal roots; (3) controlling illumination, moisture and temperature of root cuttings and matching substrates; (4) controlling hormone treating kinds,hormone treating concentration and hormone treating time; (5) selecting a cutting mode and managing the moisture after planting; (6) dividing roots and forming seedlings. According to the method, rootsections with fibrous roots of the edges of cratevareligiosa G. Forster root caps are selected as root cutting seminal roots, seed tree cap shapes are not affected, the method is simple and convenient to operate, a propagation coefficient is high, the method optimizes the thickness of seminal roots suit suitable for the root cuttings, cutting modes, matching of root cutting substrates, hormone kinds, hormone concentration and hormone treating time, bud germination time is shortened, bud germination rate, rooting rate and seedling survival rate are effectively increased, cratevareligiosa G. Forster seedlings are rapidly cultured in a short time, and the foundation is laid for development and protection of cratevareligiosa G. Forster resources.

Description

technical field [0001] The invention relates to a method for growing seedlings of fish trees, in particular to a method for raising seedlings of fish trees by root cuttings. Background technique [0002] Cratevareligiosa G. Forster is a small perennial deciduous tree of the genus Crateva in the Capparidaceae family. It is distributed in Taiwan, Guangdong, Guangxi, and Sichuan in my country. It is an excellent native flowering tree. Its wood can be used for musical instruments and detailed crafts. The material is light but hard. Fishermen in Taiwan and Ryukyu use it to carve small fish into bait, and it is poisonous to fish, so it is called "fish wood". The euclid extracted from the skin has anti-inflammatory, antibacterial, anti-tumor, diuretic, blood pressure-lowering and cholesterol-lowering effects, and the peel has certain anti-fungal effects; the fruit contains alkaloids, which can be used as adhesives, and the peel can be used as dyes. It can be seen that Yumu is an e...

Problems solved by technology

Studies have shown that the in vitro culture of plants is faster than other propagation methods with a reproduction cycle of more than one year. However, it is time-consuming to establish a sterile system in the early stage of in vitro culture. Breeding speed is not dominant

We found in the preliminary research in the early stage that the stem cuttings of Yumu have a low survival rate, and only one seedling can be cultivated at each segment, while the root cuttings are prone to adventitious buds, with a high survival rate, and each segment can produce many buds for reproduction. It is an ideal propagation material, and it is expected to improve the problem of low speed in the short-term in vitro propagation of fish wood
