Light Saturation, Photosynthesis Rate, RuDP Carboxylase Activity, and Specific Leaf Weight in Soybeans Grown Under Different Light Intensities1

Abstract

Higher light intensities during growth of ‘Wayne’ soybeans [Glycine max (L.) Merrill] resulted in increases in photosynthesis rate, light saturation intensity, RuDP carboxylase activity, and specific leaf weight. This light adaptation may explain the large reported differences in maximum photosynthesis rate and light saturation intensity for the soybean.
