Asexual rapid propagation seedling raising method for bauhinia corymbose

Abstract

The invention discloses an asexual rapid propagation and seedling raising method for bauhinia corymbose. According to the method, the tedious operation of high-pressure girdling of the bauhinia corymbose is simplified, compared with conventional high-pressure and conventional cutting propagation, the rooting starting time of the cutting stage is remarkably shortened, the rooting effects of root primordium formation, adventitious root differentiation and root system formation are greatly improved, the rooting rate and rooting quality are greatly improved, the innovative girdling and binding treatment mode and the strong seedling cultivation technology enable the rooting and seedling rate of the bauhinia corymbose to reach up to 100%. Moreover, the method has the advantages of high breeding efficiency, short cultivation period and low production cost, can quickly produce and breed a large number of high-quality big seedlings of the bauhinia corymbose, and meets the vigorous requirements of markets such as landscape architecture and vertical greening.

Description

technical field [0001] The invention relates to the technical field of plant breeding, in particular to a method for asexual rapid propagation and seedling cultivation of vines. Background technique [0002] Bauhinia corymbosa, also known as Bauhinia corymbosa, is an evergreen woody vine of the genus Bauhinia corymbosa in the family Fabaceae. It is native to Guangdong, Hainan and other places. Its flowering period is April-June and fruit period is September-December. The new leaves and tendrils of the first crown vine are beautiful and elegant, the leaves are small and strange, the flowers are numerous and fragrant, the flower color is elegant and pleasant, and the fruit pods are red and lovely. It has excellent flower, leaf and fruit value, and is an ideal tree. Climbing flowers and native vertical landscaping. [0003] The vine is usually scattered in sparse forests in valleys or sunny places on hillsides, and there are few artificial cultivation and landscape application...

AI Technical Summary

Problems solved by technology

At present, limited research reports show that the seed setting rate of the vine is not high, and it is difficult for the seeds to germinate, so it needs artificial skin grinding and germination treatment

Cuttings and layering can be used for asexual propagation, but cuttings are very prone to infection and black rot, the rooting rate of cuttings is low and the seedling period is long, the operation of layering propagation is cumbersome, and the reproduction coefficient is very low, making it difficult to scale production

In short, it is difficult to meet the production and breeding needs of S.

There are also tissue culture experiments that show that the use of jointed stems for tissue culture can grow strong fibrous roots in about 40 days by inducing rooting culture, but tissue culture has high requirements for facility conditions and operating techniques, and the cost of tissue culture is high. The rooting culture stage takes about 40 days, resulting in too long a full cycle of seedling cultivation, and it is difficult to adapt to the needs of the rapid expansion of the first crown vine
