Abstract
Salinity stress is one of the most important environmental stresses limiting economic gains from land to produce plants and crops. In this regard, an experiment was conducted to study salinity priming as an interesting strategy for increasing the salt tolerance and its effect on seed germination and growth of Cumin (Cuminumcyminum). This study was carried out using a Factorial experiment based on RCD design with 3 replications to determine the influence of priming (0, 0.5, 1 M NaCl solution for 24 hours at room temperature and control with distilled water) and osmotic potentials (0, -2, -4, -6, -8, -10 bar) on germination of Cumin plants. These researches were conducted in two separate experiments both in laboratory and greenhouse. The results indicated that seed priming treatments significantly increased germination percentage, seedling weight, germination rate, root length and plumule length. The results also showed that K + , Mg 2+ andCa 2+ concentration significantly increased in P2, P3 (0.5, 1 M NaCl ) with increasing salinity levels and Na + concentration decreased in seedling in primed seeds. To determine the influence of Salinity priming (0, 0.5, 1 M NaCl solution for 24 hours at room temperature and control with distilled water) and different salinity stress (0, 3, 6, 9, 12 ds/m) on cumin growth stages, an experiment was carried out in greenhouse condition. The results also indicated that seed priming treatments were significantly increased dry matter accumulation and relative growth rate (RGR). Furthermore the results indicated that K + , Ca 2+ and Mg 2+ concentration significantly increased in P3 (1M NaCl) and Na + concentration decreased in seedling in primed seeds compared with non-primed seeds. These results suggest that the use of NaCl pre-treatments could be a useful strategy to increase the salt tolerance of cumin plants in the long-term and to permit the establishment of cumin crop by direct sowing in a saline medium.
