Embodiment Construction

[0024] The present invention will be described in further detail through the following examples, but they are not intended to limit the protection scope of the present invention.

[0025] Collect 3,000 grains of late-maturing sweet cherry hybrid seeds Wanhongzhu and Rainey, each variety is divided into two groups, A and B, with 1,500 grains in each group, and each group is repeated three times, 500 grains / time, of which A Group is control group, adopts traditional sand storage stratification method to process stratification method germination, B group is processed with the method of the present invention, and the processing of B group is specifically as follows:

[0026] (1) Peel off the sweet cherry pulp and seeds, then put the seeds into a fine mesh bag, wash them thoroughly, store them in a cool and ventilated place at normal temperature, and dry them in the shade; the moisture content of the dried seeds should be kept at 20-24%; Pay attention to observe whether there are m...

Abstract

The invention relates to the field of seed treatment and provides a method for improving the germination rate of sweet cherry seeds. The method adopts the technical means of breaking the dormancy combined with low temperature to break the shell, promote the cracking of the core shell, increase the permeability of the testa, and help the decomposition or transformation of the inhibitory substances in the testa. Through the mechanically broken seeds, the barrier of the core shell is broken, and after low temperature treatment, the germination rate can be greatly improved. The method has strong operability, does not need to remove the seed coat, is suitable for large-scale processing, is less affected by the outside world, has a fast germination speed, does not need to use gibberellin and other hormone drugs, and has a germination rate of more than 95%, which is higher than that of the existing sand storage method. The germination rate of the treatment method can be increased by 50-80%, and the emergence rate can reach more than 90%.

Description

technical field [0001] The invention relates to the field of seed treatment, in particular to a method for improving the germination rate of cherry seeds, in particular to a method for improving the germination rate of sweet cherry seeds. Background technique [0002] Sweet cherries (cerasum and Cerasus), also known as western cherries, are generally called "cherries" in the southern region. They are native to the Black Sea coast of Europe and western Asia. They are the earliest fruits on the market in spring after Chinese cherries. One branch" reputation. Its fruit is bright in color, crystal clear and beautiful, red like agate, yellow like fat, and rich in nutrition. The fruit is rich in sugar, protein, vitamins, calcium, iron, phosphorus, potassium and other elements, so it is known as "treasure in fruit" . The sweet cherry varieties cultivated in my country are mainly European and American varieties, which perform well in some parts of northern my country. Because Euro...
