Abstract
In order to investigation of different concentrations and times of nano-TiO2 foliar application on traits of soybean (Glycine max L.) cultivar of M9, this experiment was done as split factorial based on complete randomized block design with four replications, in 2013 year, at Shar-Qods, Iran. Treatments included two factors. First factor was, different concentrations of nano titanium dioxide (0 or control, 0.01%, 0.03% and 0.05%) and the second factor was, times of foliar application of this nano particle (foliar application at vegetative and reproductive stages). Final results indicated that, effect of nano titanium dioxide concentrations with the exception of anthocyanins, was significant on the other traits (chlorophyll a, b and total and carotenoids content) but times effect of nano-TiO2 foliar application on whole traits was not significant. However, interaction's effects of concentrations and times of nano-TiO2 foliar application, was significant on the chlorophyll b and carotenoids. Maximum content of chlorophyll a and total chlorophyll, were achieved by foliar application of nano-TiO2 at 0.05% concentration and the highest amount of chlorophyll b, was obtained by interaction effect of concentration of 0.05% and foliar application at vegetative stage and the highest content of carotenoids, was achieved by spraying of 0.05% concentration of nano-TiO2 at reproductive stage.
