Abstract:
Effects of air pollution on fresh and exposed pollen grain of Bombax ceiba L. were studied in area of Nagpur. In order to study the impact of air pollution, pollen grains were subjected to LM and SEM (light and scanning electron microscopic studies). LM studies revealed that fresh pollen grains were tricolporate, with reticulate ornamentation and thick exine pattern, reticulate. According to polar view, pollen shape is more or less triangular in shape. 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 Bombax ceiba under the influence of air pollution.
