Abstract

Cigar filler, Burley and flue-cured tobacco types, each with seven cultivarsn were grown in a randomized complete block design with three replications. Leaf hair morphology, density (five parameters) and length (three parameters) were evaluated at seedling and vegetative stage. Correlations between characters were determined.

In all cultivars, leaf hairs were either tall or short and the frequency of the former was much greater than the latter at both stages of growth. Most tall hairs had glands which were unicellular or multicellular. All tall hairs had multicellular stalks while short hairs had uncellular ones. All short hairs had multicellular glands.

Significant differences among tobacco types were found only for two out of 16 parameters. Within tobacco type variabilities were significant for 13, 6 and 4 parameters for cigar filler, fluecured and Burley tobacco, respectively. Cigar filler type had the widest range for almost all parameters.

Correlations between any two leaf hair density parameters ranged from 0.18 - 1.00 and 0.65 -0.99 for seedling and vegetative stage, respectively. Correlations between the same leaf characters obtained at two stages of growth ranged from 0.30 - 0.67.
