Method for economically and quickly breaking dormancy of sand rice seeds and accelerating sand rice seeds to germinate

Abstract

The invention relates to a method for economically and quickly breaking dormancy of sand rice seeds and accelerating sand rice seeds to germinate. The method comprises the following steps: (1) collecting and washing seeds, namely removing impurities of the collected sand rice seeds for later use; (2) preparing ethephon solution, namely preparing sufficient ethephon solution with the concentration being 100-500 micromol / L; (3) processing the seeds, namely placing the sand rice seeds on a seed bed evenly and adding 6-10ml of the ethephon solution prepared in the step (2); (4) carrying out germinating experiment, namely placing the seed bed placed in the step (3) in a temperature-varying culture box for carrying out the germinating experiment; (5) counting a result, namely, daily counting the number of the germinated seeds, adding a right amount of distilled water into the seed bed till the germinating is ended. The method is capable of quickly and efficiently breaking the dormancy of sand rice seeds, causing the seeds to germinate uniformly, greatly saving time for breeding seedlings of the sand rice and providing reference methods for detecting the sand rice seeds; meanwhile, the method is low in cost.

Description

technical field [0001] The invention mainly relates to a method for breaking the dormancy of sand rice seeds and promoting their rapid germination. Background technique [0002] Sand rice (Agriophyllum squarrosum) belongs to the family Tribulus, widely distributed in Northwest my country, North China and Northeast China. It plays an important role in the vegetation succession of mobile sand dunes and is an important wild plant resource for desertification control and management. [0003] The serious seed dormancy phenomenon of A. sativa brings great inconvenience to artificial planting and seed inspection of A. sago. Wang Li et al. (2009) found that the germination rate of seeds with vitality was only 12% after being cultivated in the dark for 7 days, and the indoor emergence rate was 2%. Liu et al. (2013) found that the germination rate of sand rice seeds was less than 10% when cultivated under different temperature conditions. Predecessors have made some progress in the ...

AI Technical Summary

Problems solved by technology

Liu et al. (2013) found that the germination rate of sand rice seeds was less than 10% when cultivated under different temperature conditions.

At present, there are not many studies on the application of ethephon on native grasses, and it is the first time that the application of ethephon on sand rice is the first
