Problems solved by technology

Scholars at home and abroad have done a lot of research on the performance of salt tolerance, physiological and biochemical salt tolerance, and the effects of salt stress on their agronomic traits and grain quality in different growth stages of crops such as rice, wheat, millet, and sorghum. There are relatively few studies on salt tolerance, and most of them focus on physiological and biochemical mechanisms, and there are few related research reports on the salt tolerance of maize germplasm

Embodiment 1

[0025] The method for improving the salt-tolerant performance of corn germplasm seeds in this embodiment includes the following steps:

[0026] (1) According to "Description Standards and Data Standards for Corn Germplasm Resources", select mature corn seeds with full grains and no defects, dry them at 30-35°C for 10, and naturally cool to room temperature; then place the cooled corn seeds Soak it in a sodium hypochlorite solution with a mass concentration of 0.5 wt% for 10-15 minutes, then rinse with distilled water 3 times, and then absorb the attached water with filter paper for use;

[0027] (2) Take 1kg of the above-mentioned sterilized corn seeds and immerse them in 5L of 3wt% maltitol solution for 30min;

[0028] (3) The corn seeds after the above treatment are conventionally ventilated or dried below 30°C, and cooled to room temperature, and then conventionally stored.

Embodiment 2

[0030] The method for improving the salt-tolerant performance of corn germplasm seeds in this embodiment includes the following steps:

[0031] (1) According to "Description Standards and Data Standards for Corn Germplasm Resources", select mature corn seeds with full grains and no defects, dry them at 30-35°C for 10, and naturally cool to room temperature; then place the cooled corn seeds Soak it in a sodium hypochlorite solution with a mass concentration of 0.5 wt% for 10-15 minutes, then rinse with distilled water 3 times, and then absorb the attached water with filter paper for use;

[0032] (2) Take 1kg of the above-mentioned sterilized corn seeds, and immerse them in 10L of a 1.2wt% maltitol solution for 30min;

[0033] (3) The corn seeds after the above treatment are conventionally ventilated or dried below 30°C, and cooled to room temperature, and then conventionally stored.

Embodiment 3

[0035] The method for improving the salt-tolerant performance of corn germplasm seeds in this embodiment includes the following steps:

[0036] (1) According to "Description Standards and Data Standards for Corn Germplasm Resources", select mature corn seeds with full grains and no defects, dry them at 30-35°C for 10, and naturally cool to room temperature; then place the cooled corn seeds Soak it in a sodium hypochlorite solution with a mass concentration of 0.5 wt% for 10-15 minutes, then rinse with distilled water 3 times, and then absorb the attached water with filter paper for use;

[0037] (2) Take 1 kg of the above-mentioned sterilized corn seeds and immerse them in 8 L of a 2wt% maltitol solution for 30 minutes;

[0038] (3) The corn seeds after the above treatment are conventionally ventilated or dried below 30°C, and cooled to room temperature, and then conventionally stored.

Abstract

The invention belongs to the technical field of agricultural planting, and particularly relates to a method for improving salt and alkaline-resistant property of corn germplasm resource seeds. The method for improving the corn germplasm resource seeds has the advantages that the corn germplasm resource seeds are protectively treated by a maltitol solution; preferably, under the action of a pectinase preparation, the salt and alkaline-resistant property of the corn seeds is greatly improved, the resistance on high-concentration salt is better, the germinating rate of the corn seeds under the salt and alkaline state is favorably improved, and the like.

Description

Technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for improving the salt-alkali tolerance of corn germplasm resources. Background technique [0002] Soil salinization is one of the most important abiotic adversities that endanger agricultural production, and it has become an important environmental factor restricting the development of agriculture in my country. According to statistics, there are about 20 million hm in my country 2 The saline-alkali land in China accounts for about 20% of the arable land, and with the increase of industrial pollution, the expansion of irrigated land and protected land, and the improper use of chemical fertilizers, the secondary salinization of the soil has become increasingly serious. [0003] Studies have shown that the effects of salt stress on seed germination have the following aspects: inhibit seed germination, but do not lose vigor; delay but do not inhibit seed...
