Ecoligical And Taxonomic Significance Of Root Anatomy In Some Species And Cultivars Of Genus Canna L.

Survival potential of different plant species in varying habitats depend upon their morpho-physiological, biochemical and anatomical characteristics in that specific environment. Diversity in tissue architecture of any plant species is a promising feature in response to various environmental conditions. The present study was aimed to assess structural modifications in root of the seventeen species/cultivars of Canna L. (family Cannaceae) in relation to their wide distribution and cultivation in different habitats. Seventeen species/cultivars of Canna L. were collected from varying habitats of Faisalabad and its adjoining districts (Punjab, Pakistan). Free hand sectioning and light microscopy technique was used to prepare the double stained permanent slides for the study of different structural modifications of root in relation to variety of environmental conditions. Overall, on the basis of root anatomical studies, the wide distribution of various Canna species/cultivars can be attributed to their thicker root epidermis, large cortical cells, greater metaxylem area, smaller vessels and highest aerenchyma area and large pith area.
