Experiments were conducted with the seeds of Indigofera cordifolia Heyne ex Roth to study their germination behaviour. Seeds possess seed-coat dormancy. Seeds pretreated with sulphuric acid for ten minutes and supplied with Red light give 100 per cent germination in 3 days. Seeds are slightly positively photoblastic. The optimum temperature for germination is 30℃. Inhibitory effect of Ultra violet and a phenomenon of photoreactivation by white light has been observed. Low temperature treatment induces secondary dormancy.
