Effect of Mycorrhizal Fungus Glomus mosseae and G intraradices on Growth Characteristics of Plan Tree Platanus orientalis L in Complete and Deficit Irrigation Conditions Hamed Alipour Amraie Hamed hami99@yahoo com 14 September Department of Horticulture Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi A Nikbakht Assist Prof supervisior anikbakht@cc iut ac ir N Etemadi Assoc Prof supervisior netemadi@cc iut ac ir Abstract Plane is one of important tree used in urban landscapes of Iran In most urban lands plane trees faced with different nutritional issues including deficiency and toxicity of mineral nutrients Among problems can to point out chlorosis On the other hand one of the most limiting factor of landscapes development is securement of water for plants Deficit irrigation is a desirable method for saving water use in water deficit conditions and ultimately reducing necessary cost of water securement to landscape to used as method to reduce water need of plants The current investigation was conducted as two separated experiments to evaluate the effect of Inoculation of plants with mycorrhizal fungus on response of plane trees The first experiment was undertaken to determine the effect of inoculation with mycorrhizal fungus on response of plane saplings to different applicable water levels securement the 50 and 100 of water need In the second experiment effect of mycorrhizal fungus on uptake of nutrients and severity of cholorosis in mature plane trees was evaluated First experiment in frame of completely randomized design as orthogonal with 6 replicates and the second one in two consecutive years as completely randomised block design with 6 replications were carried out The results of the first experiment showed that with exception of irrigation level inocultion of plants with mycorrhizal fungus significantly increased majority of growth parameters viz leaf area chlorophyll and wet and dry weights of plane saplings Also the content of relative water was increased with application of mycorrhizal fungus On the other hand proline concentration in plane sapling leaves in deficit irrigation conditions was increased Concentration of phosphorus in inoculated plants as compared to non inoculated plants significantly increased too In the second experiment inoculation of plane trees with mycorrhizal fungus resulted singnificant increase in most growth and physiological parameters such as growth of current season shoots soluble sugar chlorophyll photosythetic indices and stomatal pattern e g diameter and number of open stomata and also increased uptake of some nutrients such as nitrogen and zinc as compared to control Wherease leaf chlolorosis in inoculated plants with fungus significantly reduced in comparison with control However mycorrhizal inoculation in most cases did not had significant difference to the rest treatments collectively the obtained resutls of this study revealed that inocultion of plants with mycorrhizal fungus improved plants growth under stress conditions through its positive influence on nutrient uptake chlorophyll content and subsequently increase in photosynthesis It is recommended that in dry regions and water shortage conditions the deficit irrigation method together with mycorrhizal fungus inoculation strategy will be used to reserve using water Keyword Landscape Irrigation level Plane tree Mycorrhizal Chlorophyll Chlorosis Nutrient PDF created with pdfFactory trial version www pdffactory com
