The Effect of Commercial Rootstocks and Inoculation with two Species of Mycorrhizal Fungi on some Element Uptake and Qualitative Traits of Greenhouse Cucumber

In order to study the effect of two commercial rootstocks and two mycorrhizal fungi species colonization on absorb some elements and fruit quality of greenhouse cucumber, present study was conducted in greenhouse.   a factorial experiment in a completely randomized block design with three replications was carried out, in the greenhouse of science and horticulture engineering department, University of Tabriz. The first factor was the grafting of cucumber cv. Nagin on the two rootstocks of Shintoza, and Routpower and symbiosis with two species of mycorrhizal fungi (Diversispora versiformis and Rhizophagus intraradices) considered as the second factor.     The results showed that there was a significant difference between the rootstock and species of mycorrhizal fungi in terms of qualitive traits. Inoculation of Shintoza with D. mycorrhizal fungi produced the most yield per square meter and increased the concentration of phosphorus and potassium in leaves. Also, in these treatments, qualitative traits such as total antioxidant capacity and total phenol content, fruit firmness, soluble solids content (TSS) were increased. In addition, other fruit quality charachteristics including pH and EC of fruit extract and titrable acidity of fruit were similar among all treatments.   the results showed that grafting of greenhouse cucumber on squash rootstock and using of mycorrhizal fungi to increase of fruit yield with minimal consumption of agricultural inputs, and quality characteristics and absorption of nutrients, for sustainable cucumber fruit production in greenhouse condition.
