The Study of Salinity Effects on germination Components of five Canola Genotype
Journal Title: International Journal of Farming and Allied Sciences - Year 2017, Vol 6, Issue 3
Abstract
In order to study the effects of different NaCl concentrations on the germination components of canola varieties, five genotypes including Zarfam, Sarigol, Hyola308, SLM046 and RGS003 were compared in a CRD design with three replications under four osmotic potentials (including 0, 4, 8, and 12 ds/m). .The experiment was done at the calture room in guilan university of agriculture at 2014. The results of statistical analysis showed that, all of the studied component including radicle length, shoot length, radicle / shoot ratio, radicle fresh weight, radicle dry weight and etc were significantly affected by salinity, and also showed a decreased pattern with increasing salinity. In the most of components, the highest amount was observed in control and the lowest one was in12 ds/m treatment. The results also showed that for all of studied component, 8 ds/m could be considered as salinity tolerance threshold. The difference between genotypes was significant in many cases, except root length, radicle shoot rate, and shoot growth rate. The interaction between genotype and salinity in radicle growth rate, radicle dry weight, subtraction of dry and fresh weight of radicle and radicle fresh weight were significant. These results revealed that there was a different response to salinity among the studied genotypes.
