Problems solved by technology

[0003] At present, the collection of dried pinto bean is mainly wild. With the logging of people, the wild growing area of ​​dried pinto bean has been gradually reduced in recent years, which largely limits the utilization of dried pinto bean as a medicinal plant.
The existing artificial cultivation method of dried pinto bean mainly uses the seeds produced by domestication of wild plants for sowing. First, this method has problems such as that the seeds are not easy to germinate, and the seedlings are vulnerable to diseases and insect pests. Second, this method is difficult to produce in large quantities. Unable to meet the needs of modern large-scale planting

Abstract

The invention discloses a cultivation method of fordia cauliflora hemsl tissue culture seedlings. The method comprises the following steps: (1) disinfecting fordia cauliflora hemsl seeds and inoculating in a sterile bud seedling culture medium, and carrying out illumination cultivation to obtain germinal fordia cauliflora hemsl seedlings; (2) selecting the germinal fordia cauliflora hemsl seedlings robust in growth and slicing into stems with axillary buds; (3) inoculating the sliced stems with axillary buds in an induction medium, and carrying out illumination cultivation till yellowish or milk white seedling tissues grow; (4) cutting the obtained seedling tissues into bulks and inoculating the bulks in a germination culture medium, and carrying out illumination cultivation to obtain fordia cauliflora hemsl cluster seedlings; and (5) dividing the obtained fordia cauliflora hemsl cluster seedlings, transplanting the fordia cauliflora hemsl cluster seedlings in a rooting culture medium, and carrying out illumination cultivation to obtain the fordia cauliflora hemsl rooting seedlings. By adopting reasonable culture media, the tissue culture seedling rooting rate is high. The whole method is simple to operate and can realize production on a large scale. The fordia cauliflora hemsl tissue culture seedlings obtained by cultivation are sterile and non-toxic and the survival rate after acclimatization and transplant is high.

Description

technical field [0001] The invention relates to plant tissue culture technology, in particular to a method for cultivating dried pinto bean tissue culture seedlings. Background technique [0002] Dried flower bean (Fordia cauliflora Hemsl) is a plant of the genus Dried flower bean of the Fabaceae Papilionaceae. The flowering period of dried pinto bean is from May to September, and the fruiting period is from June to November. The pods are club-shaped, flat, 7-10cm long, 2-2.5cm wide, leathery, truncate at the top, with a sharp beak, and gradually Narrow, flattened pilose, bald gradually, with 1-2 seeds; seeds round, flat, about 1cm wide, brown, smooth, caruncle membranous, wrapped in fungus stalk. Dried pineapple is pungent, flat, sweet, slightly sour, non-toxic, and has the effects of dispelling stasis and swelling, relieving pain and calming the mind, moistening the lungs and resolving phlegm. In Guangxi Zhuang and Yao people, it is used for rheumatic bone pain, bruises,...
