Foliar spraying of Alginate Oligosaccharide restores growth of wheat under chlorpyrifos stress

Article Overview

As an organophosphorus insecticide and acaricide, chlorpyrifos is suitable for the control of a variety of chewing and suction mouthpiece pests. However, excessive use will lead to changes in crop soluble protein, glutathione-S-transferase, glutathione peroxidase, etc., resulting in pesticide stress, thereby affecting crop growth.

In 2015, Zhang Shoudong, Northwest Institute of Plateau Biology, Chinese Academy of Sciences, et al. published an article entitled "Effect of Alginate Oligosaccharide on Physiological and Biochemical Indexes of Wheat Seedlings under Chlorpyrifos Stress". In this experiment, the spraying of 0.4% Alginate Oligosaccharide significantly alleviated the decrease of chlorophyll content and wheat biomass in wheat seedlings under chlorpyrifos stress, inhibited the increase of proline, soluble protein and soluble sugar content, and enhanced the resistance of wheat to chlorpyrifos stress.

As shown in the above results, chlorophyll, as an important indicator reflecting the change of leaf physiological activity, decreased significantly under chlorpyrifos stress (T0), and when the concentration of Alginate Oligosaccharide was 0.4% (T4), the chlorophyll content recovered and exceeded the normal level, which significantly alleviated the damage of chlorpyrifos to the photosynthetic function of wheat.

Proline, soluble sugar, and soluble protein, as osmotic protective substances in plants, will increase rapidly under adversity, which is the self-protection performance of plants under adversity. In this experiment, a concentration of 0.4% Alginate Oligosaccharide (T4) was used under chlorpyrifos stress (T0), and the content of the above three substances returned to normal levels, which showed that Alginate Oligosaccharide could alleviate the physiological damage of chlorpyrifos to wheat.

In summary, Alginate Oligosaccharide can regulate the physiological activity of wheat by enhancing the resistance of plants, resist the harmful effect of chlorpyrifos on wheat, and restore the normal growth of plants. With the increase of Alginate Oligosaccharide concentration, the resistance to wheat became more and more significant, and the overall concentration of Alginate Oligosaccharide with a concentration of 0.4% was the most significant alleviation.
