Biomonitoring of air pollution in a seasonally dry tropical suburban area using wheat transplants.

摘要: Air pollution has been identified as a serious problem throughout the world which causes tremendous loss to crops by affecting plant growth and yield. Earlier, air was restricted urban industrial regions. Over last few decades, however, it become evident that pollutants can be transported over long distances hence their impact may felt widely rural areas. The present study conducted evaluate of on suburban agriculture with respect changes in photosynthetic rate, stomatal conductance, water-use efficiency, height, numbers tillers, leaves, ears seeds, chlorophyll, carotenoid, protein, phenol, ascorbic acid, nitrogen sulphate-sulphur contents seed weight pot-grown wheat plants (Triticum aestivum var. HUW 468) kept at different sites around Varanasi city receiving varying levels load. Mean concentrations were monitored. clearly showed are negatively affected ambient pollutants. Reduction various parameters directly corresponded sites.
