| Abstract: | This paper presents atmospheric pollen concentrations of fifteen entomophilous trees of Eastern India. The period of anthesis and anther dehiscence varied from morning to evening. Insects and other flower visitors were found to accelerate the mechanism of pollen dispersal. The highest pollen concentration was for 267/m3 in Aegle marmelos followed in decreasing order by Eucalyptus globosus (207/m3), Cassia siamea (186/m3), C. fistula (180/m3), Delonix regia (171/m3), Butea monosperma (159/m3), Bombax ceiba (156/m3), Tectona grandis (144/m3), Terminalia arjuna (138/m3), Moringa oleifera (126/m3), Anthocephalus chinensis (114/m3), Syzygium cumini (96/m3), Dillenia indica (30/m3), Syzygium jambos (27/m3), and Kleinhovia hospita (2/m3). |
