Abstract
The pericarp ofAbelmoschus esculentus is differentiated into 3 distinct zones—the epicarp, mesocarp and endocarp. The epicarp is a product of outer epidermis and hypodermal parenchyma of the ovary wall. The growth of epicarp results from increase in the volume of cells of the periphery below the outer epidermis. In a mature pericarp the epicarpic cells become enlarged, vacuolated, thick walled and resemble collenchyma. The parenchymatous mesocarp is derived from the inner zone of ground parenchyma of the ovary wall. The large and vacuolated parenchyma of the developing mesocarp appear disorganised at maturation of the fruit. An interwoven pattern of endocarp is composed of sclerenchyma and develops from the inner epidermis together with inner sub-epidermis of the ovary wall. The dehiscence of ripe capsule ofAbelmoschus esculentus is the result of differentiation of mechanically weak cells in the median plane of each carpel, as well as in the central column and porus endocarp.
