IMPACT OF WATER QUALITY ON THE ANATOMICAL AND HISTOCHEMICAL CHARACTERISTICS OF EICHHORNIA CRASSIPES

Abstract

Water hyacinth, a worst aquatic weed and also a right candidate for pollutant removal, was collected from four different locations. Our work aimed to study the influence of water quality over the anatomical and histochemical features of water hyacinth from four water bodies. A significant difference in the size of the plant, size of the different cells in leaf, petiole and root was observed between the locations. Histochemicals were localized in the hypodermal, cortical and in some cases, stellar region of parts of water hyacinth. Water quality parameters such as pH, temperature, chloride and sulphate content of the water samples varied between locations.
