Abstract

In order to study the effect of salinity and temperature on germination and seedling growth of roselle, a factorial experiment was carried out using Randomized complete design with four replicates in Gonbad Kavous University, agronomy laboratory in May of 2011. The first factor included 5 salinity levels (0, -3, -6, -9 and -12 bar) and the second factor included 3 temperature levels (25, 30 and 35 C°). The result that showed the effect of temperature length PLUMULE, length RADICLE, GERMINATION RATE and dynamics of the seed material was significant in %1 level but on dry weight of PLUMULE in %5 level. The effect of salinity was significant in %1 on all traits expect of dry weight of RADICLE. While the effect of salinity ´ temperature was significant only on length RADICLE, dry weight of seedling, dry weight of PLUMULE and GERMINATION RATE. Regression analysis showed that the maximum reduction per unit increasing in salinity was happened in length of PLUMULE with %9.38 and the lowest decreasing was happened in dynamics of the seed material with %2.54. The most percent germination and dynamics of the seed material were happened in 31 C°. The traits that salinity×temperature interaction was significant, the minimal adverse of salt was happened in 30 C°. Thus on these results can be stated that the proper temperature for this species was 30-31 C°.
