Relation between specific leaf weight, leaf conductance, carbon exchange rate and chlorophyll contents in genotypes of upland cotton (Gossypium hirsutum Linn.)

A study of 12 genotypes of upland cotton raised in a field trial showed that small thicker leaf (i.e.. lesser single leaf area with higher specific leaf weight) is conducive for enhanced conductance with varying carbon exchange rates. Chlorophyll contents were also higher.
