Method for breeding Indian strawberry seeds

Abstract

The invention discloses a method for breeding Indian strawberry seeds, which comprises the following steps of: picking ripe Indian strawberry fruits of which the sepals are turned downwards, putting into a thermostatic blast dryer at 40 DEG C until aggregate achenes is dried, directly putting threshed dry seeds into NaOH solution for treatment, at the temperature of between 25 and 35 DEG C, illuminating for 10 hours per day, culturing for 10-15 days to ensure that the seed germination rate can reach 90 percent, putting the Indian strawberry seeds subjected to culture by preserving heat on aseptic fine river sand to form seedlings, transplanting the seedlings to flowerpots, transplanting to the field after 4 to 5 main leaves appear, and growing to form plants. The method is a simple and economic seed breeding technique, breaks the Indian strawberry seed dormancy, increases a propagation coefficient and improves an Indian strawberry rapid propagation system.

Description

technical field [0001] The invention relates to a seed propagation method, in particular to a snakeberry seed propagation method, and belongs to the field of plant propagation and plant physiology. Background technique [0002] Snakeberry ( Duchesnea indica Focke) Rosaceae Snakeberry is a perennial herb, also known as red bayberry, Longtuzhu, etc. The whole plant is used as medicine, which has significant antibacterial and antitumor effects, and has attracted the attention of scholars at home and abroad. In recent years, snakeberry has been widely used in gardens. In addition to lawns, it can also be made into beautiful bonsai. It is an excellent ground cover plant that was promoted and used in the 2008 Beijing Olympic Games. The demand for snakeberry is increasing. In recent years, studies have shown that snakeberry is a plant resource with a very broad development prospect. The fruit of snakeberry is rich in sugar, protein, tannin, suberone, lupine cheese, β Balsamin, β-...

AI Technical Summary

Problems solved by technology

[0003] However, the planting area of ​​snakeberry is very small in the south. At present, snakeberry is mainly propagated by ramets, and the thousand-grain weight of snakeberry seeds is only 0.2-0.4 grams, which is small in size and difficult to reproduce. Dominance and heredity studies

The germination rate of snakeberry is less than 50% or the germination is very irregular in the snakeberry seed aseptic seedling cultivation technology and other propagation techniques published in journals, and the processing process is complicated. Some seeds only germinate after three months of treatment, which is very important for snakeberry. The rapid propagation of berry seeds is extremely unfavorable
