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.
