Effect of effluents of a thermal power plant complex on reproductive processs of a winter season weed
- Aligarh Muslim Univ. (India)
The Kasimpur Thermal Power Plant Complex (located in the District Aligarh, Uttar Pradesh, India) runs on a low grade, sulphur rich, bituminous type of coal with a daily average consumption rte of about 3,192 metric tons during winter season. Its effluents, mainly consisting of oxides of sulphur, nitrogen and carbon as well as particulate matters, were noted to affect the reproductive behavior of Melilotus indica-a winter season weed growing wild as a component of a grassland community. The samples consisting of 10 plants were collected at monthly intervals from 5 sites located about 0.5, 2, 6, 12 and 20 km leaward from the Complex. Emergence of inflorescence was delayed at the polluted sites. However, fruit formation started simultaneously (in March) at all the five sites. The pollution induced senescence of floral buds, flowers and fruits, but did not alter markedly weight of seed and fruit.
