Abstract
Since plant growth and development are controlled by plant growth regulators and per-sowing seed treatments have proven advantageous to germination, seedling growth and yield of several field crops, in the present study the growth and developmental responses of rice (Oryza sativa L.) cultivar Sadri to soaking seeds for three days in 0.0, 50 and 100 mg l indole butyric acid (IBA), gibberellic acid (GA ) and salicylic acid (SA) 1 3 were investigated. Percent germination and germination rate rose significantly in all the hormonal treatments. Root and shoot lengths were increased significantly by nearly all the treatments. The fresh and dry weights at seedlings were affected the most by IBA. Significant increase in chlorophyll, carotenoids and antocyanins contents of leaves occurred by soaking seeds in hormonal solutions. Except for IBA, treatments did not change tillers number significantly. Panicle grain numbers increased significantly by all the treatments, whereas, 1000 kernels weight was affected only by IBA and SA at 50 mg l . IBA at 50 mg l had the highest impact on grain 11 yield with 9.4 compared to 7.5 ton per hectare in control which is more than 25% increase in grain yield. Among the treatments, IBA at 50 mg l significantly affected all the yield tested components. These finding strongly 1
