Abstract

Abstract:

The present paper describes the pollen morphology of 31 species of the genus Quercus

from China. The pollen grains were all examined with light microscope and scanning electron

microscope, and those of some species under transmission electron microscope.

Pollen grains of the genus are spheroidal or subspheroidal, 16.8-50.4μm in diameter, 3-

colporoidate or 3-colpate. The exine is 2-layered, 0.4-1.8μm thick, sexine thicker than nexine,

granulated tuberculate or verrucate.

Key words: Quercus, Pollen morphology, Microstructure, Ultrastructure
