Seed treatment method for improving and enhancing vigor of sweet corn seeds and special compounding initiator for seed treatment method

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...

Problems solved by technology

The same initiator has different priming effects on different genotypes of sweet corn seeds, so whether this initiator has a priming effect on strengthening sweet corn varieties remains to be further verified. In addition, the prior art has only proved that a single initiator The priming effect of corn seeds has certain limitations, and the cost of riboflavin is relatively high, so it is less likely to be used in large quantities in production
