Pollen production in some plant taxa with a supposed role in allergy in Eastern India.

This paper deals with the production of pollen grains per anther per flower of 15 probably allergenic pollen producing angiospermic plant taxa growing in Eastern India. The selected plant taxa includes Ailanthus excelsa, Alstonia scholaris, Argemone mexicana, Azadirachta indica, Cassia alata, C. siamea, Dalbergia sissoo, Holarrhena pubescens, Lagerstroemia speciosa, Madhuca indica, Milletia pinnata, Mimusops elengi, Morus alba, M. indica and Murraya paniculata. Among the investigated taxa, A. excelsa produces the highest number of pollen grains (1635180) followed by C. siamea (1589245) and A. mexicana (463800). The production of pollen grains is lowest in H. pubescens (2500), followed by A. scholaris (5175), A. indica (6220) and M. paniculata (11200). [ABSTRACT FROM AUTHOR]
