Characterization of two species of <i>Physalis</i> L. by using fruit and seed characteristics

Abstract

The fruit and seed characteristic of Physalis peruviana L. and P. pruinosa L. were studied using fruit and seed colour, and shape along with dimensions and spermoderm pattern. The basic spermoderm sculpture was reticulate and mircro-reticulate in P. peruviana and P. pruinosa respectively. The epidermal cells of P. peruviana were large, irregular, non-isodiametric, and 08 - 15 gonals whereas in P. pruinosa small, irregular, and conjugate. Anticlinal boundaries of cells in P. peruviana observed sinuate, channeled, and thick while in P. pruinosa were straight to slightly sinuous and thin. Periclinal cell wall boundaries were observed as highly concave and straight to slightly concave in P. peruviana and P. pruinosa respectively. The study is useful for identification of both species by seeds.
