Air pollution induced alterations in assimilate partitioning in Anagallis arvensis L
- Aligarh Muslim Univ. (India)
The Thermal Power Plant Complex of Kasimpur (Aligarh, UP, India) emits enormous amounts of oxides of sulfur, nitrogen, and carbon as well as particulate matters on consuming 3192 MT of coal/day. These effluents induce significant alterations in carbon allocation in Anagallis arvensis populations. Monthly samples of 10 plants each were collected on random basis at seedling to mature stage from 0.5, 2, 6, 12 and 20 km leeward from the power plant. In oven dried samples, assimilate partitioning was noted to be more severely altered by the air pollutants in the seedling stage. In 2 and 3 months old populations, photosynthate allocation to root and shoot was not altered noticeably. Considerable changes in carbon allocation were noted in 4 mo old mature stage. The carbon allocation to fruit was 3 fold and to seed was about 4 fold greater in the population thriving 20 km away from the source than in those growing in the vicinity of the source. Assimilate partitioning was linearly related to the distance from power plant and the productivity of the populations.
