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 increasing the germination rate of sweet cherry seeds. According to the method, a technical means of breaking dormancy by combining low temperature with dehulling is adopted to facilitate cracking of nuclear shells, increase the permeability of seed husks and be conductive to decomposition or transformation of inhibiting substances in the seed husks. The mechanically deshelled seeds break the impedance of the nuclear husks and are then subjected to low temperature processing, so that the generation rate is greatly increased. The method is high in operability, free of removal of the seed husks, applicable to massive processing, little affected by external influences, high in germination velocity and free of use of hormone drugs, such as gibberellins; the germination rate can reach over 95%; the germination rate can be increased by 50% to 80% compared with that of an existing processing method adopting stacking sand stratification; the emergence rate can reach over 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 cherry (cera sum and Cerasus), also known as western cherry, is generally called "cherry" in the southern region. It is native to the Black Sea coast of Europe and western Asia. "The good name. 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 European sweet cherry generally needs a low temperature of 0-7.2°C for 600-1400 hours to complete ...
