Effect of Cement Dust Accumulation on Seed Germination and Growth of <I>Shorea robusta</I> Seedlings

Abstract

Trees were selected in eight different directions and in each direction five distances were taken in the vicinity of cement factory for collecting the seeds and to observe their germination and growth parameters. It was observed that seeds collected from control sites (10 km away) from the factory, showed significantly higher germination and growth parameters compared to those collected near the factory.
