Effect of Salinity Tension and Foliar Application of Nano-Oxide on Some of the Physiological Chracteristics of Rapeseed (Brassica napus L.) and Camelina (Camelina sativa L.)
Abstract:   (479 Views)
In order to investigate the effect of salinity tension and zinc nano oxide on physiological parameters of Rapeseed and Camelina, a factorial experiment was conducted based on a completely randomized design with three replications in the greenhouse conditions of Department of Biology of Urmia University in 2012-13. The factor of zinc nano oxide was investigated at three levels of zero,  25 and 100 milligram per liter as foliar application and salt tension factor at zero, 75 and 150 milliMolar  concentrations. The results showed that the reaction of two plants to salinity tension was quite distinct. So, in 150 million salinity tension, the highest chlorine ion accumulation was observed in Camelina plant in the root, but in Rapeseed, more chlorine ion was accumulated in the leaf. The ratio of potassium to sodium in Canola leaf was higher in comparison with the root, whereas in Camelina, the ratio of potassium to sodium was higher in the root. Relative water and proline content of leaf and root were increased by increasing salinity tension in both plants but the amount of increasing the relative water content and the accumulation of proline in leaf and root at Camelina  were higher in comparison with Canola. With increasing salinity tension up to 150 milliMolar total chlorophyll, chlorophyll a and b showed a significant decrease in both plants. But the amount of this reduction in Rapeseed was significantly higher than that of Camelina. Foliar application of zinc nano oxide at 25 milligram per liter in both Rapeseed and Camelina in addition to the traits of potassium / sodium ratio in leaf and root, in other investigated traits, the effect of salinity tension was reduced significantly, which can be used to reduce the effect of salinity tension.
Keywords: Accumulation of proline, Total chlorophyll and Relative water content.
