Use of Leaf Size-Leaf Area Relationship to Estimate Leaf Dry Matter in Tobacco (Nicotianci tabacum L.}.

Abstract

The relationships of leaf size to leaf area and the leaf area to leaf dry weight were determined in tobacco plants as an estimate of leaf dry weight.
Three leaf positions on the stalk, the 5th, 10th, and 15th, were utilized. Leaves were removed, maximum length and width measured, and their area traced to the nearest cm2 using graph paper. Leaves were then dried in an air-forced drying oven.
The study had revealed that 5th and 10th leaf positions had no significant effect on leaf size-leaf area relationships. The leaf area showed significant relationship to leaf dry weight in tobacco leaves.
