Abstract

The effect of DROUGHT STRESS and MYCORRHIZAL SYMBIOSIS on the colonization, root and leaf phosphorous content, root and leaf PHOSPHATASE activity, root volume and area as well as shoot dry weight of a variety of HULLESS BARLEY were evaluated using a completely randomized experimental design (CRD) with 3 replications. Treatments were three levels of DROUGHT STRESS of 30, 60 and 90% field capacity and two levels of mycorrhizal with and without inoculation. According to the results, the highest value of leaf phosphorous (1.54 mg/g) was observed at MYCORRHIZAL SYMBIOSIS against severe drought treatment. Root PHOSPHATASE activity was highest (297.9 OD min -1 FW-1) at severe DROUGHT STRESS with MYCORRHIZAL SYMBIOSIS which in comparison with mild stress in the presence of mycorrhiza showed 16.6 fold increasing. The control and non-mycorrhizal symbiosis treatments had highest root dry weight (0.091 g). The lowest root volume (0.016 cm2) observed at MYCORRHIZAL SYMBIOSIS × severe drought treatment. Generally, Inoculation of barley seed with mycorrhiza at severe water stress could transport more phosphorous to shoot, especially leaf via inducing of leaf and root PHOSPHATASE activity. Also, in addition to supply of nutrient sources especially phosphorous for plant, MYCORRHIZAL SYMBIOSIS could play an important role in withstanding water stress in plant via increasing of root dry weight and area.
