To investigate trunk injection treatment effects on eliminating chlorosis disorder and improving the growth of plane trees (Platanus orientalis L.), an experiment was arranged in a factorial experiment based on a randomized complete block design at Lavark Reasrch Farm, Isfahan University of Technology, Isfahan, Iran, with three replications and four treatments. Treatments consisted of different sources of iron (iron aminolate, iron gluconate, iron citrate, iron sulfate) at six concentrations (0 as control, 0.1, 0.25, 0.5, 0.75, and 1%) for each treatments. The measured traits included photosynthetic pigments, iron content, chlorophyll fluorescence, leaf protein content, appearance quality index, relative leaf water content, and electrolyte leakage of tree leaves. The results indicated that trunk injection of iron aminochlate and iron gluconate at 0.75 and 1% concentration had the most significant positive effect on the most of the measured traits compared to the other treatments. Therefore, the use of iron aminochlate and iron gluconate treatments improved the visual appearance of plant trees by increasing the concentration of photosynthetic pigments. The results showed that iron aminochlate and iron gluconate treatments at the level of 0.75% and 1% had the most significant positive effect on the most measured traits compared to the other experimental treatments. Iron aminochlate and iron gluconate treatments improved the appearance of the sycamore tree by increasing the amount of photosynthetic pigments. Also, increasing the concentration of iron used in each treatment in most traits improved the measured characteristics. Based on the results, the interactions of iron aminochlate treatment with a concentration of 1% showed the most significant positive effect compared to the control treatment in the most traits. Therefore, the trunk injection method using aminochlate treatments is recommended to improve different traits in sycamore trees.
