A new application of an ester concentrated compound agent in improving apple resistance to saline-alkali stress

Abstract

The invention relates to a new application of an ester concentrated compound agent in improving apples' resistance to saline-alkali stress. Products with brassinolide and strigolactone as active ingredients are applied to plants subjected to saline-alkali stress, which can significantly enhance the ability of plants to resist saline-alkali stress, reduce the oxidative damage caused by saline-alkali stress to plants, and alleviate Yield and quality decrease due to salinity.

Description

technical field [0001] The invention relates to a new application of an ester concentrated compound agent in improving apples' resistance to saline-alkali stress. Background technique [0002] There are two main types of adversity stresses encountered by plants during their growth and development, namely abiotic stresses and biotic stresses. Among the abiotic stresses encountered during plant growth and development, soil salinization is not only a difficult problem in agricultural production in my country, but also a recognized worldwide problem. It not only affects the normal production process of agriculture, but also hinders the high yield of agricultural products. And stable production, because saline-alkali soil contains more saline-alkali components, it seriously affects the quality of the soil and the ecological process of the soil, thus affecting the growth of animals and plants. The area of ​​saline-alkali soil in my country accounts for about 10% of the world's sal...

The impact of high pH stress on plant roots is huge. The roots of rice seedlings will turn yellow immediately in alkaline solution. The high pH around the plant roots will cause the accumulation and precipitation of metal ions and phosphorus, which will damage the root tissue structure and lead to a decrease in root activity. The absorption function of the root system is weakened, and the plants cannot normally absorb water and nutrients from the roots. The root cells die and turn yellow, and then the leaves wilt, and the plants cannot perform normal photosynthesis, thus losing normal physiological functions.

At the same time, high pH will also cause nutrients such as iron and phosphorus in the soil to condense into lumps, which cannot be absorbed by plants normally and affect plant growth.

[0005] Brassinolide and strigolactone have been used as a class of antioxidants for plant stress resistance. However, no one has studied the effect of brassinolide and strigolactone compound solution on plant salt. The effect of alkali stress
