Abstract

The present invention discloses novel application of ascorbic acid to improvement of plant photosynthesis efficiency. The invention is as below: using ascorbic acid solution with concentration gradient of 0.1,0.5,2,5,10 mmol / L to treat different varieties of plants for 24 hours, and respectively measuring physiological and biochemical parameters of leaves; stressing by using AlCl3 with different aluminum concentration gradients and different aluminum concentration gradients containing 2 mmol / L-ascorbic acid for 24 h, and measuring the photosynthetic characteristic parameters and physiological and biochemical indices of leaves respectively; and comparing the experimental results with the control plants. After ascorbic acid administration, H2O2 accumulation in aluminum sensitive soybean and Al tolerant soybean leaf cells decrease, and H + - pump activity and stomatal aperture and photosynthetic parameters are restored and improved; and these changes help promote plant stomatal opening and enhance photosynthesis and respiration of soybean, thereby enhancing the resistance to aluminum stress of plants.

Description

technical field

[0001] The invention belongs to the field of plant photosynthesis and relates to a new application of ascorbic acid, in particular to the application of ascorbic acid in improving plant photosynthesis efficiency. Background technique

[0002] Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into organic carbohydrates and store energy. As we all know, the essence of crop production is that crops use light energy to convert CO in the air 2 Translated into an organic matter storage process, dry matter accumulation depends on carbon assimilation. It is generally believed that 90% to 95% of the biological yield of crops comes from the products of photosynthesis, and only 5 to 10% of the substances come from the mineral nutrients absorbed by the roots. Stomatal conductance in photosynthetic parameters is a measure of the smoothness of water and gas exchange between plants and the atmosphere. Stomata are important ...
