Abstract

In order to investigate the effect of nano-iron chelate and the time of application of this element on some morphological and physiological characteristics of Rose damascene, genotype A104, a factorial experiment with a randomized complete block design was conducted in a two-year-old rose damascene farm. The first factor was different concentrations of nano-iron chelate (0, 0.5, 1, 1.5 and 2 g/l) and the second factor was application time of nano-iron chelate (0, 10 and 20 days after the beginning of the growth of plants in the growing season) with three replications. The maximum leaf width and wet and dry weight of leaves were observed at the concentration of 1.5 g/l of iron on the 20th day of spraying. The highest increase in the height of the flowering stem was related to the 20th day spraying with a concentration of 2 g/l of iron. The highest number of flowers was recorded in nano-iron chelate 1.5 g/l on the 20th day, which was not significantly different from the concentration of 2 g/l on the 20th day of spraying. The highest concentration of iron, nitrogen, magnesium, phosphorus and potassium elements in leaves was recorded on the 20th day of the experiment in plants sprayed with 2 g/l of nano-iron chelate. According to the results of the research, foliar spraying of plants twenty days after the start of seasonal growth with 1.5 g/l of nano iron chelate is recommended to improve the morphophysiological characteristics of rose.
