Abstract: In order to study effect of GA₃ and IAA on dormancy and seedling growth of fresh sesame [Sesamum indicum (L.)] seeds”an experiment was carried out in laboratory of the Department of Seed Science and Technology, College of Agriculture, Junagadh. Seed treatments consisted of control (untreated seeds), GA₃ (100, 200, 300 ppm) and IAA (100, 200, 300 ppm). The objective of this experiment were to determine the effect of gibberalic and indole acitic acid on germination of sesame and to find an effective method for breaking its seed dormancy. Results showed that GA₃ found effective for germination percentage, speed of germination and shoot length while IAA was found effective for increasing root length of seedlings, seedling dry weight and vigour index.
