Morpho-Anatomical Structure and DNA Extract of Sun and Shade Leaves of Jute (Corchorus capsularis L.)

摘要

A study on the comparison of morpho-anatomical structure and DNA extract of sun and shade leaves of jute (Corchorus capsularis L.) was done. Morphological structure of exposed the Corchorus capsularis are taller, leaves are lighter, thicker, bigger and broader than shaded. Anatomical form of exposed jute have many stomata on the leaf, two layered palisade and compact spongy layer of leaf lamina, compact cells of the mesophyll of midrib, compact parenchyma cells of the cortex of the stem, and larger vacuole in the pith of the stem. While shaded jute has less stomata on the leaf, one layered palisade and loosely arranged cells in the spongy layer of leaf lamina, loosely arranged cells of the mesophyll of midrib, loosely arranged parenchyma cells of the cortex of the stem, and small vacuole in the pith of the stem. In terms of DNA extract, exposed leaves of jute (Corchorus capsularis L.) has more DNA extract than that of the shaded leaves. Thus, morpho-anatomical structure and DNA extract of exposed and shaded jute (Corchorus capsularis L.) differ.
