Influence of Vesicular-arbuscula Mycorrhizal Fungi (Glomus spp.) on the Response of Grapevines Rootstocks to Salt Stress
Hoda A. Khalil

Abstract:
Mycorrhizal fungi, a symbiotic relationship between plant roots and beneficial fungi are supposed to impart the stress tolerance in the host plants. The present study was conducted to evaluate the effectiveness of AM fungi with three grapevines rootstocks under salt stress. Three grapevines rootstocks (Dogridge, 1103 Paulsen and Harmony) were irrigated at three different NaCl concentrations measured by electrical conductivity (0.65, 1.56 and 4.68 dS m-1). Salinity decreased Arbuscular Mycorrhizal (AM) colonization. In both the AM and non AM, plant height, stem diameter, leaf area, total leaves number/plant and total dry weight were decreased under salinity. The plants inoculated with the AM fungus had significantly higher growth parameters compared to the non-inoculated plants. Increasing the salinity level tended to increase the proline accumulation and the concentrations of leaf N, Na and Cl while the chlorophyll content, leaf total carbohydrates, leaf P and K decreased. On the contrary, Inoculated the seedlings with AM tended to increase the levels of chlorophyll content, proline, total carbohydrates and the concentrations of leaf P and K. Whereas leaf N, Cl in the second season and Na of inoculated seedlings was significantly lower than that of un-inoculated ones.
