Effects of Mycorrhizal Inoculation on Health Appearance, Physiological Characterstics and Photosynthetic Behavior of Plane Trees

Plane tree is one of the major tree used in urban landscapes of Iran. One of its serious problem is chlorosis and leaf abscission in many parts of the country. The current investigation was conducted to evaluate the effect of inoculation of plane trees (Platanus orientalis L.) with mycorrhizal fungus on response of plane trees in two years (2011 and 2012). An open field experiment conducted based on a randomized complete block design with 4 treatments and 6 replicates in Isfahan University of Technology. Treatments were as follwoings: livestock manure¡ chemical complete fertilizer¡ manure fertilizer mycorrhiza fungi and control (no fertilizer). The results showed that inoculation of plane trees with mycorrhizal fungus caused singnificant increase in most growth and physiological indices such as growth of current season shoots¡ total soluble sugar content¡ chlorophyll content¡ photosythetic indices and stomatal pattern ( diameter and number of open stomata).¡ To sum up the results revealed that inocultion of plants with mycorrhizal fungus¡ improved plants growth accordingly through its positive influence on stomata behavior¡ chlorophyll content and subsequently increase in photosynthesis.
