Problems solved by technology

This is not only labor-intensive and time-consuming, but also the seeds often rot during the sand storage period or the low-temperature stratification time is not well grasped, which affects the normal release of dormancy of the seeds. After sowing, the seeds cannot germinate or the germination rate is low, resulting in delays in the production season and economic losses.

Embodiment 1

[0017] The seeds of Duli pear collected in Xinjiang in 2016 were rinsed with distilled water to remove impurities and then air-dried in a cool place. The seeds were stored in ziplock bags at room temperature. Get the stored Duli pear seeds and imbibition in distilled water for 8 hours, then use a mass fraction of 2% sodium hypochlorite aqueous solution for disinfection for 3 minutes, then rinse with distilled water for 3 to 5 times, and then wash the seeds with secondary distilled water (i.e. ascorbic acid concentration of 0, as a control group), 10mmol / L ascorbic acid aqueous solution, 25mmol / L ascorbic acid aqueous solution, 50mmol / L ascorbic acid aqueous solution, 75mmol / L ascorbic acid aqueous solution, 100mmol / L ascorbic acid aqueous solution soaked at normal temperature (22 ℃) for 3 hours, after treatment Blot the moisture from the surface of the seeds with sterilized filter paper.

[0018] The above-mentioned treated seeds were placed in an environment of 16 hours of li...

Embodiment 2

[0029] In 2016, the Zhengzhou Comprehensive Experimental Station of the National Pear Industry System reached the physiological maturity stage. The ripe fruits of the early crisp red pears were harvested and immediately transported back to the laboratory. Store in a ziplock bag at room temperature. Take the stored Zaosu red pear seeds and absorb them in distilled water for 24 hours, carefully peel off the inner and outer seed coats of the seeds, do not damage the seed embryos, and then disinfect them with 2% sodium hypochlorite aqueous solution for 2 minutes, and then use distilled water After washing 3 to 5 times, the seeds were washed with twice distilled water (that is, ascorbic acid concentration is 0, as a control group), 1mmol / L ascorbic acid aqueous solution, 5mmol / L ascorbic acid aqueous solution, 10mmol / L ascorbic acid aqueous solution, 15mmol / L ascorbic acid aqueous solution, 20mmol / L ascorbic acid aqueous solution was soaked at normal temperature (22°C) for 3 hours,...

Embodiment 3

[0035]In 2015, after the fruits of Mahali cherries in Sanyuan County, Shaanxi Province matured and softened, the seeds were taken out, washed with distilled water to remove impurities, and then dried in a cool place. The seeds were stored in ziplock bags at room temperature. After taking the stored Mahalli cherry seeds and imbibing in distilled water for 24 hours, carefully peel off the inner and outer seed coats of the seeds (Mahalli cherry seeds have a harder outer seed coat, in order to ensure that the embryo can fully absorb the ascorbic acid solution , so peel off the outer seed coat during the test), do not damage the seed embryo, and then disinfect it with a 2% sodium hypochlorite aqueous solution for 3 minutes, then rinse it with distilled water for 3 to 5 times, and then use the seeds twice. Soak in distilled water (that is, the ascorbic acid concentration is 0, as a control group), 10mmol / L ascorbic acid aqueous solution, 30mmol / L ascorbic acid aqueous solution, 50mmo...

Abstract

The invention discloses an application of ascorbic acid as a sleep release accelerating agent in breaking seed dormancy. According to the invention, a fact that ascorbic acid can break seed dormancy and can promote germination and the build of normal seedling form is found for the first time. Through the utilization of the method provided by the invention, the effect of breaking dormancy is the same as the effect of gibberellin, but the cost is low and no pollution is generated; compared with low-temperature stratification treatment, the method has greatly shortened time for breaking the seeddormancy, and the operation is convenient; and the guarantee of the emergence rate of seeds in conventional seedling breeding is facilitated. The method provided by the invention is simple and convenient to operate, is economical, practical and environmentally friendly, does not need special equipment, can be operated on a large scale, and can be demonstrated, promoted and applied to cultivation practice.

Description

technical field [0001] The invention belongs to the technical field of conventional seedling cultivation, and specifically relates to the use of ascorbic acid as a dormancy-relieving accelerator in breaking seed dormancy. Background technique [0002] Seeds are the reproductive system of seed plants and play an important role in the continuation of species. However, many plant seeds have dormancy characteristics to ensure that plants can survive unfavorable environments and survive. Seed dormancy refers to the phenomenon that vigorous mature seeds (or germination units) cannot germinate under any combination of suitable physical environmental factors (temperature, light / dark, etc.) within a certain period of time. [0003] It is precisely because the seeds have dormant characteristics, so in conventional breeding and cultivation practice, after collecting the seeds, they must be treated with low-temperature stratification, that is, before the soil is frozen in November, the...
