Relationship between leaf area index, specific leaf weight and assimilation rate in rice genotypes

Relationship between leaf area index, specific leaf weight and assimilation rate in rice genotypes

Madras Agricultural Journal 82(11): 616-617

The leaf area index (LAI) and specific leaf weight (SLW) were determined at anthesis and assimilation rate was computed for the entire growth period for 30 rice genotypes grown under wetland conditions during kharif 1987 at Bangalore. Genotypes differed markedly in LAI, SLW and assimilation rate. As LAI increased SLW decreased. Maximum assimilation rate was observed with LAI of 4-5. Assimilation rates decreased with higher LAI due to mutual shading.
