Development of Stomata in some Solanaceae

Abstract

The present paper deals with the ontogeny of stomata in 12 species of the Solanaceae. The mature stomata are anomocytic, anisocytic, paracytic and diacytic. The development of anomocytic stomata is haplocheilic or perigenous, while that of the other types is syndetocheilic or mesogenous. Abnormal stomata with a single guard cell, unequal guard cells, aborted guard cells and arrested development have been observed. Contiguous stomata are also common. The abnormal stoma with a single guard cell is formed due to disintegration of one of the guard cell before or after pore formation.
