Embodiment

[0024] 1) The riboflavin sodium phosphate aqueous solution with a concentration of 0.01% (w / v); the disodium succinate aqueous solution with a concentration of 0.5g / L; and the acetylsalicylic acid aqueous solution with a concentration of 0.5mmol / L; The volume ratio is 3:1:20, 5:1:30, 7:1:40, and 9:1:50. Mix riboflavin sodium phosphate aqueous solution with disodium succinate aqueous solution and acetylsalicylic acid aqueous solution to obtain The compound initiator combined with sand was used to prime the enhanced sweet corn seeds, and the unprimed seeds were used as the control (CK).

[0025] Initiation conditions: 922g of sterilized sand with a diameter of 2mm sieved and compounded initiator 150ml, the percentage of compounded initiator and sand is 16.3% (v / w), put 200 seeds, and initiate for 24 hours under 20°C and dark conditions . After priming, wash the seeds and dry them back indoors (20-25° C.) until the water content of the seeds is the same as before priming.

Abstract

The invention provides a seed treatment method for improving and enhancing the vigor of sweet corn seeds and a special compounding initiator for the seed treatment method. The compounding initiator is a mixture formed by a riboflavin sodium phosphate water solution with the concentration being 0.01% (w/v), a sodium succinate dibasic water solution with the concentration being 0.5 g/L and an acetylsalicylic acid water solution with the concentration being 0.5 mmol/L according to the volume ratio of 3-9:1:20-50. The seed treatment method for improving and enhancing the vigor of the sweet corn seeds through the compounding initiator is also within the protection range of the invention. The compounding initiator prepared from riboflavin sodium phosphate, sodium succinate dibasic and acetylsalicylic acid at different proportions is designed and combined with sand priming to treat and enhance the sweet corn seeds, several commonly-used vigor indexes are measured, and finally the formula of the compounding initiator capable of remarkably improving and enhancing the vigor of the sweet corn seeds is obtained. In addition, the high cost of riboflavin single dosage in the prior art can be greatly reduced through compounding of the three reagents, and certain universality is achieved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a seed treatment method for improving and strengthening the vigor of sweet corn seeds and a special compound initiator thereof. Background technique [0002] Fortified sweet corn is rich in nutrients and has a high economic value due to its unique taste. In recent years, the market demand has soared. However, due to the recessive gene mutation of endosperm, the starch synthesis of sweet corn is hindered, the grain shrinks, the seed vigor is low, and the field emergence rate is low, which seriously restricts its development. At present, many researches try to fundamentally improve seed vigor with breeding methods, including traditional hybrid breeding, emerging mutation breeding, genetic engineering, etc., but the breeding methods are not only complicated in mechanism, high in cost, difficult to operate, but also have hidden dangers in biological safety. Ther...
