Effects of ethylene inhibitor and promoter on photosynthetic characteristics of soybean (Glycine max) seedling leaves
Different concentrations of ethylene inhibitor AVG (aminoethoxyvinylglycine) and promoter ACC (1-aminocylopropane-1-carboxylic acid) were sprayed to seedlings of soybean cultivar Tiefeng 31, and their effects on photosynthesis and CO<sub>2</sub> response curves were studied. The results...

| description | Different concentrations of ethylene inhibitor AVG (aminoethoxyvinylglycine) and promoter ACC (1-aminocylopropane-1-carboxylic acid) were sprayed to seedlings of soybean cultivar Tiefeng 31, and their effects on photosynthesis and CO<sub>2</sub> response curves were studied. The results showed that higher AVG concentration resulted in significant increase in the net photosynthetic rate, transpiration rate and stomatal conductance and decrease in intercellular CO<sub>2</sub> concentration compared with the control. Light saturation point (LSP), photosynthetic rate at light saturation point, apparent quantum efficiency (AQE), CO<sub>2</sub> saturation point (CSP) rate, carboxylation efficiency (CE) and maximum rate of RuBP regeneration were promoted by AVG treatments, while the light compensation point (LCP) and CO<sub>2</sub> compensation point (CCP) were depressed by AVG treatments. In addition, biomass and leaf area per plant were enhanced, while the chlorophyll contents, ethylene production and stomatal density were significantly reduced by different concentrations of AVG treatment. The precursor of ethylene, ACC had an opposite effects on the photosynthetic parameters compared with AVG treatment. The results above indicate that AVG treatment can improve photosynthetic characteristics of soybean seedling leaves. |
