Title: A STUDY ON THE POLLEN MORPHOLOGY OF 4 GENERA OF FAMILY ERICACEAE IN NORTHEAST OF CHINA

All of the pollen grains o f the 4 genera are characterized in tetrahedral tetrad. Pollen grains of the 4 g enera are spheroidal or subspheroidal with 3-colporates, which shaped as half-c olpi due to two neighborly grains of tetrahedral tetrad link together. Exine is composed with two layers in LM. The ornamentation of the exine is reticulate or granulate. The mean size of the pollen grains ranges from 34.0 to 43.7μm. Pol len grains are diverse in size and in ornamentation of the exine. These can be taken as the characters for identification of species.Read More
