Structural, Functional And Biochemical Responses Of Datura Innoxia Mill. To Coal-Smoke Pollution, Azamal Husen, Muhammad Iqbal
Dr. Azamal Husen
Effect of coal-smoke pollution on Datura innoxia Mill. was investigated. D. innoxia has shown that leaf length, single leaf area, total leaf area and leaves per plant decreased but leaf biomass increased under pollution stress. Epidermal features of upper and lower leaf surface responded to pollution stress differently. Rate of photosynthesis and stomatal conductance were low, internal CO2 concentration was high and levels of chlorophyll a and b, total chlorophyll and carotenoids were reduced in polluted condition. Levels of proteins, reducing sugar in roots and sulphur contents in leaves, stem, roots and seeds showed significant increase under the polluted condition. …
