Drought stress can cause yield decrease of many crops in many arid and semiarid regions of the world. Recent droughts have decreased yield of citrus in the country. Arbuscular mycorrhiza employs the mechanisms such as increased nutrients uptake to alleviate the effects of water stress in host plants. The effects of arbuscular mycorrhizal fungi, Glomus mosseae and Glomus versiforme on growth and nutrients uptake by sour orange (Citrus aurantium) were assessed in a sterilized soil in a greenhouse experiment. The experiment had a completely randomized design in a factorial arrangement with two factors and three replications for each treatment. The factors were mycorrhizal treatments at three levels (inoculation with Glomus mosseae, Glomus versiforme, and the control) and water stress at four levels (irrigation intervals of 2, 4, 6 and 8 days). Water stress decreased shoot and root dry weights and nutrients uptake (P, N, Fe, Cu, Mn), but increased Zn content in the shoots and roots. Shoot and root dry weights and contents of P, N, K, Cu, Mn and Zn were more in mycorrhizal plants than in the control plants. Root colonization was higher in mycorrhizal than nonmycorrhizal plants. In mycorrhizal citrus rootstock, root colonization decreased as drought stress levels increased. |
