EFFECT OF INDUSTRIAL EFFLUENT ON THE MORPHOLOGICAL PARAMETERS AND CHLOROPHYLL CONTENT OF ARACHIS HYPOGAEA L.
K. Abraham*, G. Sudhakar and T. Damodharam
A pot culture experiment was conducted to study the effect of sugar industry effluent on seed germination, seedling growth and chlorophyll content of Arachis hypogaea L. (Variety. Narayani) have been estimated at different effluent concentrations (25%, 50%, 75% and 100%) and day’s intervals (10th, 20th and 30th Day). The germination percentage of seed, seedling growth and chlorophyll content showed a gradual decline with increase in effluent concentration. It has been observed that at 25% and 50% effluent concentration, there is growth in the root length, an increase in shoot length and total chlorophyll content up to 20 days. After 20th day there is decline in all the parameters observed. However, at higher concentrations of the effluent, toxic effects were observed from 20th day. This suggests that the effluent can be used safely for Arachis hypogaea cultivation, only after proper treatment and dilution.[Full Text Article]
