Leaf physiology and anatomy of soybean genotypes differing in leaf photosynthetic ability

Soybean phenology and yield as influenced by environmental and management factors

“…Dornhoff andShibles (1976), andFord (1984) reported positive correlations between photosynthetic rate 20 and specific leaf weight in soybeans.…”

“…Ford (1982) concluded that if LAI is not constant, photosynthetic rate per unit leaf area (PS) may not be related to yield and that LAI is often a more important determinant of productivity. He believes that the inverse relationship between LAI and PS explains why poor or negative correlations are often found between productivity and PS.…”
