Abstract

The invention discloses a preparation for efficiently inducing chromosome doubling of winter buds of mulberries, and belongs to the technical field of chromosome doubling. The preparation for efficiently inducing chromosome doubling of winter buds of mulberries is specialized for a compound regulator for mulberry winter bud chromosome doubling and has the advantages of simplicity in manufacturing,low cost, convenience in use, higher induction efficiency and better repeatability. With application of the preparation, mulberry winter bud meristem cell differentiation can be induced, chromosome doubled mulberry twigs with high success rate can be obtained, the effect is obvious, and the preparation is suitable for popularization and application in wide mulberry breeding and cultivation in China. Double self-stirring effects can be generated on each ingredient through the self-shaking stirring effect of the self-shaking stirring cone and the similar boiling phenomenon generated when compressed inert gas in the magnetic core balloon leaks so that the uniform mixing of each raw material is accelerated, the difficulty of on-site preparation and on-site use is reduced and the preparation efficiency of on-site preparation and on-site use is effectively improved.

Description

technical field [0001] The invention relates to the technical field of chromosome doubling, in particular to a preparation for efficiently inducing chromosome doubling of mulberry winter buds. Background technique [0002] Mulberry belongs to the family Moraceae and is a deciduous tree. Mulberry leaves are oval and are feed for silkworms. Leaves are ovate or broadly ovate, apex pointed or acuminate, base round or heart-shaped, sawtooth thick and blunt, leaves of young trees often have lobes, deep lobes, glabrous above, sparsely hairy below along the veins, vein axils tufted hairs. Juhuaguo (Mulberry) is purple-black, light red or white, juicy and sweet. Flowering in April; fruit ripening in May-July. [0003] Mulberry is a deciduous tree with a height of 2-6 feet; it has a well-developed root system, strong germination, fast growth, light-loving, and medium branch density; it can resist drought and cold, and is relatively resistant to temperature and humidity; it also ha...
