Embodiment 1

[0018] Example 1: Take 30 sweet corn seeds (W22 sweet corn reporter line) with full grain size and similar size, soak them in 70% ethanol for 5 minutes, soak them in 0.1% mercuric chloride solution for 8 minutes, and wash them with water. The seed soaking solution used was 5 μg / ml Hrf protein solution, and the surface spreading agent Silwet L-77 was added at a final concentration of 0.3%. The surface-sterilized corn seeds were placed in 5 μg / ml Hrf protein solution and soaked at 28° C. for 12 hours. Get the treated seeds and sow them in a conventional way.

Embodiment 2

[0020] Take 30 sweet corn seeds (W22 sweet corn reporter line) with full grain size and similar size, soak them in 70% ethanol for 5 minutes, soak them in 0.1% mercuric chloride solution for 8 minutes, and wash them with water. The seed soaking solution used was 10 μg / ml Hrf protein solution, and the surface spreading agent Sylgard 309 was added at a final concentration of 0.1%. The surface-sterilized corn seeds were placed in 5 μg / ml Hrf protein solution and soaked at 28° C. for 12 hours. Get the treated seeds and sow them in a conventional way.

Embodiment 3

[0022] Take 30 sweet corn seeds (W22 sweet corn reporter line) with full grain size and similar size, soak them in 70% ethanol for 5 minutes, soak them in 0.1% mercuric chloride solution for 8 minutes, and wash them with water. Put the surface-sterilized corn seeds in 10 μg / ml Hrf protein solution, add the surface spreading agent Silwet L-77 with a final concentration of 0.3%, and soak the seeds at 25°C for 24 hours. Get the treated seeds and sow them in a conventional way.

Abstract

The invention discloses a method for improving vitality and cold resistance of corn seeds. The method comprises the following steps of: disinfecting surfaces of the corn seeds according to the conventional method; cleaning the corn seeds with clean water; soaking the corn seeds at a temperature of 18-30 DEG C for 12-24 hours, wherein seed soaking liquid is Hrf protein solution with the concentration of 5-10 mug/ml; and sowing the corn seeds according to the conventional method. The seed soaking method according to the invention is simple and easy to implement; the seed soaking liquid is a green and environment-friendly pure biological preparation without agricultural chemical pollution or chemical reagent pollution; and therefore the Hrf protein solution is an ideal seed soaking liquid, and the method is an ideal seed soaking method.

Description

technical field [0001] The invention relates to a method for improving vigor and cold resistance of corn seeds. Background technique [0002] corn( Zea mays L. ) is one of the main food crops in my country and an important source of livestock feed. Corn is also the most widely used food crop, the most developed products, and the largest amount of industrial raw materials. In addition, sweet corn, a new corn variety that integrates grain, fruit, vegetables and feed, is also in production. As the most important storage organ in maize production, the study of maize kernel is very important. In particular, sweet corn and super sweet corn have a high seed breakage rate, weak productivity, low field emergence rate, and high seed production costs, which are generally not easily accepted by farmers. The germination rate is one of the important indicators of the quality of corn seeds, and it is an important basis for the annual production success and income of seed production uni...
