Effect of Vehicular Air Pollution on Pollen Viability

摘要

The present investigation deals with study of vehicular air pollution on pollen viability of Butea monosperma, Dalbergia sisso, Cassia fistula and Cassia siamea. The study was carried out in the forest, irrigated and polluted areas of Karimnagar district. The pollen of these species were treated with acetocarmine stain method and was observed a considerable reduction in pollen viability in the plants of traffic polluted area. It has observed that the mean percentage of pollen viability i.e., Butea monosperma has 91.2% in forest locality, 96.3% in irrigated locality, and 84.1% in polluted locality. Pollen viability of Dalbergia sissoo is 95.12% in forest locality, 95.47% in irrigated locality, and 76.79% in polluted locality whereas pollen viabilityof Cassia fistula is 95.12% in forest locality, 95.47% in irrigated locality, and 76.79% in polluted locality and pollen viability of Cassia siamea is 95.12% in forest, 95.47% in irrigated, and 76.79% in polluted localities. The pollen from forest and irrigated localities have high percentage of viability when compare to polluted area.
