AIRBORNE POLLEN--FLORA IN AN OUTDOOR SITE IN GWALIOR (MP)

An aeropalynological survey was conducted for two years, between September 2012 to August 2014 by using “Burkard Portable Spore Trap Sampler” at Kampoo, an outdoor site at Gwalior (MP). Total 33 pollen types were identified. The pollen grains belonged to angiospernic families. Dicotyledonous taxa contributed maximum number of pollen grains as compared to monocotyledons. Observations indicate that pollen of Poaceae was maximum followed by Asteraceae, Mimosaceae and Cassia type. On the basis of mode of pollination amphiphilous type of pollen were maximum followed by entomophily and anemophily. Total as well as individual pollen types and their number displayed distinct seasonal periodicity in their incidence.
