Abstract

A method for detecting the germination percentage of cotton seeds includes such steps as shearing a small opening at the micropylar end of seeds to expose the radicle by 2-3 mm, immersing seeds in the warm water at 53-56 deg.C until the water is cooled to 39-41 deg.C, immersing the seeds in the water at 38-42 deg.C in culture case for 25-65 min, putting the seeds on paper bed, culturing at 28-32 deg.C, examining the germination first time after the seeds are cultured for 24 hr, and examining the germination second time after the seeds are cultured for 48 hr.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for detecting the germination rate of cotton seeds. Background technique [0002] As the most basic means of production, cotton seeds play a very important role in cotton production. The germination rate of cotton seeds is one of the important indicators of the quality of cotton seeds. With the continuous improvement of the industrialization of cotton seeds, refined cotton seeds such as delinting and coating are widely used in production, which greatly improves the quality of cotton seeds, especially The germination rate of cotton seeds was significantly improved. However, due to various reasons, the annual loss to production due to the germination rate of cotton seeds is still very serious, and it is very important to do a good job in the detection of germination rate. [0003] Rapid and accurate determination of cotton seed germination rate plays a very important role in t...
