The pericarp ofSolanum tuberosum is 30–40 layers thick. It is a multilayered region of the fruit made up of outer epidermis and the periclinally divided cells of the outer hypodermal layers. The mesocarp is developed from the middle layers and partly from the outer hypodermal cell layers of the ovary. The increment in number of cell layers of endocarp is only upto 0·3·0·8 cm size of the fruit. There are no endocarpic outgrowths. The small chambers are formed by the placental outgrowths surrounding individual seeds. The outgrowths develop further and contact the innermost layer of endocarp or the septa of the fruit.
