摘要

The pollen morphology of 11 species distributed in seven genera belonging to family Cucurbitaceae has been studied using light microscopy (LM) as well as scanning electron microscopy. Pollen morphology of this family is diverse and is almost europalynous. Nearly all types of pollen belonging to different size class and shape class with a variety of exine sculpturing are found in the family. Pollen grains are usually triporate to tricolporate, prolate, oblate-spheroidal, spheroidal, to suboblate, radially symmetrical, and isopolar. The common exine pattern is reticulate of various forms ranging from finely reticulate to coarsely reticulate with some species having echinate type of exine ornamentation, for example, Cucurbita pepo and Praecitrullus fistulosus. Most of the studied species are somewhat triangular with respect to equatorial outlook and circular to elliptic in polar outlook. The palynological characteristics of the members of the family are useful in identification of taxa at generic level mostly. Based on the present study it is not recommended to wholly solely depend upon the pollen morphology for the identification of taxa especially at specific levels because very minor differences regarding pollen characters exist among the species of the same genera.
