Abstract
The aim of present investigation was to study the effect of Indole - butyric acid (IBA) and Gibberellic acid (GA3) on growth of corn (Zea mays L.) single cross 704. Two field experiments during the 2009-10 and 2010-11 growing seasons were conducted near the city of Shiraz. The experiment was randomized complete blocks, split plot design with three replications. The foliar application of two growth regulators (GA3, IBA) in two physiological sensitive growth phases, i.e. 4 to 6 leaf and flowering stages constituted the main plots and concentration of 0, 50 and 100 mg L -1 of both IBA and GA3 formed the subplots. Evaluated physiological traits include, net assimilation rate, crop growth rate and leaf area index. Compared to the control, the greatest leaf area index is obtained by applying GA3-50 in 4-6 leaf stage of growth. The highest increase of crop growth rate (11.4 gr m -2 day -1 ) belonged to IBA100GA3-100 treatment in 4 to 6 leaf stage. The best net assimilation rate was obtained in the treatment IBA100GA3-50 with 2.72 gr m -2 day -1 . Totally, the results show that in both stages of growth, application of IBA and GA3 improves growth parameters.
