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

   Chlorpyrifos, as an organophosphorus insecticide and acaricide, is suitable for the control of various chewing and sucking mouthparts pests such as wheat. However, excessive use will lead to changes in crop soluble proteins, 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, etc. published an article "Effects of Alginate Oligosaccharides on Physiological and Biochemical Indexes of Wheat Seedlings Under Chlorpyrifos Stress". In this experiment, spraying 0.4% concentration of Alginate oligosaccharides 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 wheat Resistance to chlorpyrifos stress.


Test Results:




(Note: CK: distilled water treatment, T0-T4: 0/0.05%/0.1%/0.2%/0.4% Alginate oligosaccharide treatment under chlorpyrifos stress)


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




Proline, soluble sugar, and soluble protein, as osmotic protection substances in plants, will increase rapidly under adversity conditions, which is the self-protection performance of plants under adversity. In this experiment, under the stress of chlorpyrifos (T0), Alginate  oligosaccharides (T4) at a concentration of 0.4% were used, and the contents of the above three substances all returned to normal levels. It can be seen that Alginate oligosaccharides can alleviate the physiological damage of chlorpyrifos to wheat.


In summary, Alginate oligosaccharides can regulate the physiological activity of wheat by enhancing the resistance of plants, resist the damage of chlorpyrifos to wheat, and restore the normal growth of plants. And with the increase of the concentration of Alginate oligosaccharides, the resistance to wheat increased more significantly, and the overall performance was that the concentration of 0.4% Alginate oligosaccharides had the most significant mitigation effect.

The role of gamma-aminobutyric acid in agriculture

图片
  γ-aminobutyric acid (CAS number: 56-12-2), (GABA for short), with a relative molecular weight of 103.1, is a four-carbon, non-protein amino acid, which is widely used in vertebrates, plants and Widespread in microorganisms. The content of GABA in plant tissues is extremely low, usually between 0.3 and 32.5 μmol/g.  It has been reported in the literature that the enrichment of GABA in plants is related to the stress response experienced by the plant. When subjected to stress such as hypoxia, heat shock, cold shock, mechanical damage, and salt stress, it will lead to the rapid accumulation of GABA.  It has become a research hotspot to process plant food raw materials into GABA-rich functional products after a certain stress treatment or through microbial fermentation to increase the GABA content in the body.  As a novel functional factor, GABA has been widely used in the food industry.  Foods developed using raw materials such as GABA-rich  germinated brow...

Analysis on the role of rhizobia in soybean planting

图片
Rhizobium soybean is a live microbial preparation. The rhizobia in the root nodules and the legumes are mutually beneficial: the organic matter produced by the legumes through photosynthesis is partly supplied to the rhizobia; the ammonia produced by the rhizobia through biological nitrogen fixation is supplied to the legumes plant. , it fixes free nitrogen in the air to supply soybeans to meet soybean demand for nitrogen. It is a good measure to increase soybean yield, save fertilizer and reduce pollution, and has been valued by researchers around the world. First, the role of rhizobia 1. Nitrogen fixation Soybean rhizobia uses the products of soybean photosynthesis as energy, and converts nitrogen in the air into nutrients required for soybean growth and development. Rhizobium and soybean have a symbiotic nitrogen fixation relationship. At the beginning, soybean rhizobia fixed little nitrogen, until flowering to drum. The initial stage of grain is the peak of nitrogen fixation by so...

The new cotton shoot-controlling product--prohexadione calcium, which is better than uniconazole, does not cause premature aging!

图片
Uniconazole is a triazole plant growth regulator widely used in cotton production. In recent years, it has an obvious effect on controlling the growth of cotton, promoting flowers and peaches, and can also increase the ratio of cotton double bolls. Welcomed by some cotton farmers.  Today, I will introduce to you a new type of plant growth regualtor, which is more effective than Uniconazole. It is better than Uniconazole because it is not prone to premature aging and defertilization of cotton. 1. What is prohexadione calcium Prohexadione calcium is a new type of plant growth regulator developed by Japan Combina Chemical Industry Co., Ltd. It interferes with the synthesis of gibberellic acid in plants, reduces the content of gibberellic acid in plants, controls leggy growth, promotes flowering and fruiting, and increases yield. Make its root system developed, protect cell membrane and organelle membrane, and improve crop resistance ability. So as to inhibit the upper vegetative growt...
