The Effect of Application of Different Levels of Axing and Gibberellins at Different Growth Stages on Quantitative and Qualitative production Components of Field Bean
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 4, Issue 6
Abstract
This experiment was carried out in Shahid Salemi experimental field of Islamic Azad University of Ahvaz, In Northeast of Ahvaz at latitude 31°20´ N and longitude 48°40´ E and 22.5 m above the sea level in the summer of 2010. The experiment was carried out as split plot in the form of randomized complete block design with three replications. The main treatment included three different growth stages of crop (V0 = vegetative phase, V1 = flowering phase, V2 = podding and grain filling phase), and the sub treatment included 4 levels of auxin hormone (A0 = 0, A1 = 3, A2= 7, A3 = 20 ppm) and three levels of gibberellins (G0 = 0, G1 = 5, G2 = 15 ppm). Grain yield, biological yield, harvest index, and protein percentage of grain were affected by experimental treatments. In evaluating the main effects, the highest rate of studies traits was obtained at growth stages in V2 phase. Moreover, due to the application of 7ppm auxin and 15ppm gibberellins the highest rate of studied traits was obtained. In studying the interactive effect of growth stages and auxin hormone, the highest rate of grain yield was obtained during podding and grain filling stage and application of 7ppm auxin. In addition, investigating the interactive effect of growth stages and gibberellins showed that the highest rate of grain yield was obtained at V2 phase and application of 15ppm gibberellins. Examining the interactive effect of auxin and gibberellins showed that the highest rate of grain yield was obtained through the application of 7ppm auxin and 15ppm gibberellins.
