Abstract
Regulating effects of plant growth regulator( Luxing) on energy metabolism in the process of photosynthesis, respiration and transpiration at soybean (Glycing soja)seedling stage were studied. The results indicated that spraying plant growth regulator(Luxing) at soybean seedling stage can obviously improve photosynthesis and respiration of soybean leaves. Gross photosynthesis is 4.96 g/(m2·h) higher than that of ck, net photosynthesis is 1.60 g/(m2·h) higher, and transpiration is 18.50 g/(m2·h) lower. In the area of energy changing, gross energy absorption is 18.30 kJ/(m2·h) higher than of ck, the fixed energy in the process of gross photosynthesis is 63.14 kJ/(m2·h) higher than of ck, the dissipating energy of transpiration decreases by 44.84 kJ/(m2·h) , and the fixed energy of dark respiration increases by 45.80 kJ/(m2·h) . In general, spraying plant growth regulator(Luxing)at soybean seedling stage can increase energy absorption, fixing, and efficiency of light energy utilization by 0.42% .
