ANATOMY AND SURFACE MICROMORPHOLOGY OF TOMATILLO FRUIT (PHYSALIS IXOCARPA BROT.)

摘要

The fruit structure of tomatillo, a new vegetable crop in Poland, has not been yet investigated. The surface of the fruit as seen in SEM shows amorphous and cristalline wax-like deposits. Almost every forth or fifth epidermal cell has a small appendix covered with cuticle and wax-like substance. No trichomes were found. The anatomical structure of the fruit is similar to that of several other Solanaceae species. The epidermis shows polygonal, tabular cells with a large nucleus. Sub- epidermis is composed of 1-4 layers of collenchyma-like cells, sometimes very flattened and compressed.
