Problems solved by technology

At present, the domestic corn planting adopts the method of drill and hole sowing, and most of the seeds are directly planted in the ground. The disadvantage of this method is that the seed emergence and seedling time are inconsistent, and the lack of seedlings is serious, which brings huge troubles to corn production.

Embodiment

[0013] A method for soaking corn seeds in combination with low-concentration GA at a constant temperature, characterized in that the method includes preparation of a low-concentration GA working solution, disinfection, seed soaking, constant temperature treatment, and germination, and the specific steps are as follows:

[0014] ① Preparation of low-concentration GA working solution: Accurately weigh 0.1g of GA and dissolve it in a little 95% ethanol, then dilute to 10L with tap water, which is 10ppm GA working solution;

[0015] ②Disinfection: Disinfect Zhengdan 958 seeds in warm water at 50°C for 10 minutes;

[0016] ③ Seed soaking: According to the ratio of seed quality: low concentration GA working solution volume = 1:5, soak the seeds in 10ppm GA working solution;

[0017] Constant temperature treatment: carry out constant temperature treatment at 28°C for 24 hours;

[0018] Germination: The seeds after constant temperature were placed in a sterilized germination box ...

Abstract

The invention discloses a method for immersing corn seeds in low-concentration GA (gibberellic acid) at constant temperature and belongs to the field of conventional breeding of plants. Firstly, a low-concentration GA working solution with the concentration of 10 ppm is prepared; the corn seeds are put into a seed bag, disinfected at the temperature of 50 DEG C for 10 min and then immersed in the GA working solution in the proportion of seed mass to the volume of the low-concentration GA working solution being 1:5; the corn seeds are subjected to constant-temperature processing at the temperature of 28 DEG C for 1d; the processed corn seeds are put in a germination box containing sand and sprout at the constant temperature of 25 DEG C for 10 days (12h in light and 12h in darkness).

Description

technical field [0001] The invention relates to a method for combining low-concentration GA with constant temperature soaking of corn seeds, which belongs to the field of conventional plant breeding. Background technique [0002] Corn is an important food, economic and feed crop with wide application and large demand, and occupies an important position in the national economy. Therefore, increasing corn production plays an important role in ensuring national food security, promoting animal husbandry and rural economic development, and increasing farmers' economic income. At present, domestic corn planting adopts the method of drill sowing and hole sowing, and most of the seeds are directly planted in the ground. The disadvantage of this method is that the seedling emergence and seedling time are inconsistent, and the lack of seedlings is serious, which brings huge troubles to corn production. Therefore, improving the rate of full seedlings, full seedlings and strong seedlin...
