Method for quickly relieving dormancy of pyrus betulaefolia seeds

Abstract

The invention discloses a method for quickly relieving dormancy of pyrus betulaefolia seeds, relates to hormone treatment and germination acceleration, and belongs to the field of plant physiology and production cultivation. According to the method, by removing peels of the seeds, covering the seeds with degreasing cotton, treating the peeled off seeds with a gibberellin and glucose mixed solution and using proper exogenous hormone and the moisture retention property of the degreasing cotton, the dormancy of the seeds is broken through. The method has the advantages of simple steps, low loss, relatively short time and the like; the effect of relieving the dormancy is good, the number of mildewed seeds is relatively small, and germinated seeds can be used for sowing or subsequent experiment.

Description

technical field [0001] The invention relates to a method for rapidly relieving dormancy of pear pear seeds, relates to hormone treatment and germination acceleration, and belongs to the field of plant physiology and production cultivation. Background technique [0002] Pear seeds have dormancy characteristics, and whether the seeds can germinate is directly related to the types and contents of the internal hormones in the seeds. Treating seeds with exogenous hormones can supplement the deficiency of endogenous hormones, promote metabolism, and break dormancy. [0003] At present, gibberellin is commonly used to treat seeds in production. Usually the seeds are soaked in the gibberellin solution first, and then low-temperature stratification is performed, and there are also low-temperature stratification first and then soaked in the gibberellin solution. However, the effect of simply using gibberellin to treat seeds with seed coats and not stratified is poor. Contents of t...
