The present study reports the effect of thiourea, I. A. A., ascorbic acid and coumarin both individually and jointly on the germination and growth of seedlings of Amaranthus spinosus Linn. Seeds of this plant are found to be negatively photoblastic. Thiourea at a concentration of 4 per cent has been found to induce germination in light to the extent of 48 per cent. The study suggests that I. A. A. and ascorbic acid although by themselves incapable in inducing germination of A. spinosus seeds in light, are effective in enhancing the capacity of thiourea for inducing germination. Specific interaction of I. A. A. and ascorbic acid in the seedling growth has been observed.
