Detoxification and rapid propagation method of snow white strawberries

Abstract

The invention relates to a detoxification and rapid propagation method of snow white strawberries. The detoxification and rapid propagation method comprises the following steps: S1, explant selectionand surface cleaning, namely selecting 2-4cm stem tips of snow white strawberry grape stems as explants, and carrying out surface cleaning; S2, sterilization, namely placing the surface-cleaned explants on a workbench for sterilization; S3, induced cultivation, namely picking 0.5mm stem tips of the explants by using a dissecting needle under an anatomical lens, and inoculating the 0.5mm stem tipson an induced culture medium for induced culture for 50-60 days to obtain young seedlings of the snow white strawberries; S4, virus detection and seedling selection, namely carrying out virus detection on the young seedlings of the snow white strawberries by using a virus kit, and selecting the young seedlings, reaching the standard, of the snow white strawberries; S5, subculture multiplication culture, namely transplanting the young seedlings, reaching the standard, of the snow white strawberries into a multiplication culture medium, and carrying out subculture once every 30 days for 5-6 times; and S6, rooting culture, namely transplanting young seedlings with the plant heights being 3-5cm of the snow white strawberries into a rooting culture medium for culture for 20-30 days to obtain snow white strawberry plants.

Description

technical field [0001] The invention belongs to the technical field of agricultural seedling cultivation, and relates to a method for detoxification and rapid propagation of Snow White strawberries. Background technique [0002] Strawberry belongs to Rosaceae Strawberry is a perennial herb and is an important economic crop. Strawberry pulp contains a lot of nutrients such as protein, sugar and pectin. Its vitamin C content is higher than that of apples, grapes and other fruits. It tastes sweet and sour and delicious, and is very popular among people. In addition to eating fresh, strawberries can be processed into products such as canned food, jam, fruit wine and beverages.

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a method for detoxification and rapid propagation of Snow White strawberry, which uses stolons as stem tip stripping tissues, and breeds detoxification strawberry seedlings through tissue culture technology, so as to solve the problem of the actual production process of Snow White strawberries. The problem of slow propagation of seedlings and poisonous seedlings can improve the yield and quality of Snow White strawberry. The virus-free seedlings of Snow White strawberry cultivated have the advantages of strong plant growth, well-developed root system, strong and neat individual growth, etc.
