Rubber factory effluents from the GAICO rubber latex centrifuging factory were analysed and found to contain high amounts of total suspended and dissolved solids. Sulphate, phosphate and total nitrogen were also present in significant amounts. At higher concentration (above 50%) of effluent, the seed germination percentage of V. radiatus [V. radiata] was retarded. Diluted effluent (up to 50%) favoured seedling growth. Length of root system, shoot system and number of lateral roots were increased by low concentrations of effluent.
