Abstract

The invention discloses a method for treating aged cauliflower seeds and application thereof, wherein a method for treating aged cauliflower seeds comprises the following steps: dissolving potassium nitrate, spermidine and spermine in water to prepare a treatment method for treating aged cauliflower seeds. liquid. The seeds, vermiculite and treatment solution were sequentially added to the container with lid and mixed, and placed in an incubator for dark cultivation. After the cultivation, the seeds were separated from the vermiculite, and the seeds were washed with running water and then slowly dried. The dried seeds are selected for sowing or storage. The invention can improve the vigor of the aged cauliflower seeds, especially the germination and emergence ability of the seeds under low temperature conditions, and improve the activities of the antioxidative enzymes CAT, POD and APX of the imbibed seeds. The treated cauliflower seeds can be stored for more than 24 months under the conditions of room temperature and below, and relative humidity of 10% to 40%.

Description

Technical field [0001] The present invention relates to the field of Chenhua seed processing technology, especially in the treatment method and application thereof. Background technique [0002] Range seeds, such as blue cars, cauliflower, etc. belong to the Cross flower, is one, two-year vegetable crop, rich nutrient, large cultivation area, and important economic and edible value. The seeds have achieved the highest activity level when the seeds reached the physiological maturity period, and then the seed activity continued to decrease with the increase in storage time. The ruled seeds will be stored from harvesting seeds. Due to natural aging or inadvertent storage environments, seed viability will decrease year by year. As the storage time increases, the seedling speed is slow, and the desired semantian time has increased, and the seedling rate is lowered, especially during the winter low-income in winter. Due to the relatively high price of the seed class, the seed vitality ...
