GENETIC ANALYSIS OF STOMATAL DENSITY AND LEAF AREA IN ACID LIME (CITRUS AURANTIFOLIA SWING.)

Published on

Highly significant variation for stomatal density, leaf area and stomatal number per leaf
was observed in 27 acid lime (Citrus aurantifolia Swing.) clones. They were grouped into
low, medium and high density categories bued on their stomatal density. No appreciable
differences among the clones for stomatal size were observed.The genotypic coefficient of
variation for all the characteristics were higher than the respectively phenotypic coefficient
of variation. High heritability was observed for stomatal density, indicating lower
influence of environmental factors on this characteristic. The lower GA estimated for
stomatal density indicated that the heritability for the characteristic may be of nonadditive
nature. Correlation studies revealed negativeassociation between stomatal density and leaf
area. J'he role of stomata determining several properties in plants, such u, tolerlUlCe to
diseues and drought, plant vigour and yield, indicated scope for selection and breeding in
acid lime by applying selection pressure for stomatal density.
 

Keywords: Acid lime, stomatal density, leaf area, genetic variability, heritability, correlations.
