Method for quickly breaking dormancy of birch-leaf pear seeds with hydroxylamine chloride

Abstract

The invention provides a method for quickly breaking dormancy of birch-leaf pear seeds with hydroxylamine chloride, which relates to the breaking of seed dormancy and seed germination and belongs to the technical field of plant production. The method comprises the following steps: peeling off pericarp of a ripening fruit; rubbing the peeled fruit to eliminate pulp; soaking seeds in sodium hypochlorite (NaClO) of which the mass volume ratio is 20 percent to remove the pulp adhered to seed capsules; sterilizing the seeds by soaking the seeds in a mercuric chloride solution of which the mass volume ratio is 0.1 percent for 8 minutes; taking the cleaned birch-leaf pear seeds, and presoaking the seeds for 24 hours respectively in the hydroxylamine chloride of which the mass volume ratio is 0.8 percent at room temperature; and sowing the seeds after washing the seeds for 5 to 6 times. The main basis of the method is that the birch-leaf pear seeds have the characteristic of embryo dormancy, the dormancy of the birch-leaf pear seeds can be broken after the treatment with the hydroxylamine chloride, and the method can promote the seed germination, increase the seed germination rate, and has tidy germination.

Description

technical field [0001] The invention is a method for breaking the dormancy of pear rootstock seeds—Durium pear seeds and rapidly promoting their germination, and belongs to the fields of plant life science, seed science, and seed production and trade. Background technique [0002] One of the biggest threats in agriculture is that the sown seeds do not have the germination ability to make the cultivars germinate and grow normally and fail to achieve the purpose of production. The purpose of carrying out seed inspection is not only to evaluate the quality of seeds before sowing, and to prevent the use of fake and inferior seeds for sowing, but also to provide seeds for producers, processors, warehouse managers, seed merchants, farmers, certification agencies and government seed management departments. Seed quality information, good management and good use of seeds are the basic guarantees for high yield, high quality and high efficiency in agriculture. In crop breeding, seed ...
