Description :
Effects of air pollutants on fresh and exposed pollen grain of RicinuscommunisL. were studied in area of Nagpur. In order to study the impact of air pollutants, pollen grains were subjected to LM and SEM (light and scanning electron microscopic studies). LM studies revealed that pollen grains appeared prolate spheroidal, circular polar outline, elliptic equatorial outline, tricozocolporate, costate -vestibulate. Colpi narrowly elliptic, tapering, tips acute, exine thick. Whereas in exposed pollen grains, shrinkage in its size and breakage of exine was noticed. SEM studies of exposed pollen shown some particulate matter was attached to its surface. The studies have discussed the structural changes in pollen characteristics of RicinuscommunisL. under the influence of air pollutants.
