Response of seed priming on seed germination and seedling growth in basil

In order to evaluate the effect of priming on seed germination and seedling growth in basil ( Ocimum basilicum L.), an experiment was conducted based factorial in randomized complete block design with three replications in western of Iran. Priming factor including: witness, KCL 2% and priming time including: 0, 3, 5, 7 and 9 hours. Results showed that Priming was affected on radicle length, radicle dry weight, stem let dry weight, germination percentage and speed germination. KCL 2% had better results due to negative osmotic adjustment. Seed priming had significant affected on radicle length, radicle dry weight, stem let length and stem let dry weight. Seed priming in 7 hours had positive affected on all studied traits. The highest radicle length, radicle dry weight and stem let length obtained from 7 hours. According to the results Priming and priming time role played in plant germination. Among treatments KCL 2% and 7 hours had an important role in germination.
