the effects of three arbuscular mycorrhizal fungi (amf) species (glomus versiforme, claroideoglomus etunicatum and rhizophagus intraradices) were studied on the growth parameters and nutrient uptake of three apple rootstocks (m.9, m.7 and mm.106). the soil medium contained a high level of calcium carbonate (38.65%). the results showed that amf inoculation could increase almost all growth parame...

Abstract This research was performed in a completely randomized block design with four replications to investigate zinc (Zn) and manganese (Mn) nutrition effects on greenhouse tomato (Lycopersicon esculentum Mill. cv. HAMRA) in a perlite-containing media. Experimental treatments were: (1) control (Mn and Zn-free nutrient solution), (2) application of Mn in a concentration equal to the full Hoag...
Pistachio is one of the economically important horticultural crops in Iran. The main pistachio-producing areas in Iran are located at the edge of the desert and are affected by soil and water salinity. Water and nutrient uptake by the root decreases under saline conditions. In this study, the effects of foliar growth regulators applied at different times on the nutrient uptake and leaf nutrient...
An experiment was conducted to select the optimum nutrient solution for growing lettuce (Lactuca sativa L.) under hydroponic conditions (open system) and Shahrekord climate, as a completely randomized design with five different nutrient solutions and three replicates, in Shahrekord University. The nutrient solutions were: 1) Research Station for Floriculture and Greenhouse Vegetables (the Nethe...
Laboratory animal models are an important part of test design. Certain conditions such as microbial contamination in diets of these models could affect the results of experiments. One of the most important routes that predispose to contamination is generated through feeding of laboratory animals. This study aimed to show the effect of gamma irradiation in reducing bacteria concentrations,...
influence of arbuscular mycorrhizal fungi (amf) (glomus etunicatum, g. intraradices and glomus versiforme) and external phosphorus supplement (8 and 35 mg p kg-1 soil) on leaf p, zn, cu and fe nutrition of 4-month-old tea(camellia sinensis) was studied in an glass house pot experiment. the highest leaf p concentration (up to 59.43% increase) was found in g. versiforme inoculated seedlings gro...
in this study, effect of irrigation duration on concentration of some macro and micro nutrient elements in ‘thompson navel’ orange leaves grafted on three rootstocks was evaluated as a factorial experiment in completely randomized block design. factors included rootstocks in three levels (poncirus trifoliata, citrus aurantium and troyer citrange (citrus sinensis ´ poncitus trifoliata)) and irri...
