Abstract:
Iris germanica 8# and Iris tectorum were treated with different concentrations of NaC1 solutions: 0, 0.3%, 0.6% and 0.9%. The samples were analyzed for salt resistance after 4 days and 8 days of contact time. The results showed that the relative permeability of plasma membrane and the MDA content of I. germanica 8# were lower than I. tectorum. The SOD activity, proline and soluble protein contents of I. germanica 8# were much higher than I. tectorum. This research confirms that I. germanica 8# has a higher ability for salt resistance than that of I. tectorum. Low permeability and low MDA content, along with high SOD activity and high proline and soluble prolein contents are five important physiological indexes for salinity resistance in Iris L.
