Abstract: (52 Views)
In order to investigate the effect of drought stress and biofertilizers from Mycorrhiza, azotobacter and azospirillum on the yield and biochemical characteristics of two wheat cultivars, a randomized complete block design in the form of split-factorial experiment was conducted with three replications in the crop year 2014-2015 in Poldakhter city. Drought stress in the main plots consisted of three levels of full irrigation, interruption of irrigation from the spike stage and interruption of irrigation from the seed filling stage. The sub-plots factorially included biofertilizer factor in four levels of control (without fertilizer), mycorrhiza inoculation, mycorrhiza+aztobacter inoculation, mycorrhiza+azespirillum inoculation, and the cultivar factor included Chamran and Behrang cultivars. Drought stress in the flowering stage caused a decrease in the content of chlorophylls and most elements, including nitrogen, phosphorus, potassium, copper and manganese, in shoots and seeds, but increased the content of proline and antioxidant enzymes. The content of most of the elements in aerial parts and seeds and the concentration of proline and antioxidant enzymes were higher in the Chamran variety than Behrang. The simultaneous use of mycorrhizae and growth-stimulating bacteria increased the content of most elements in shoots and seeds compared to the control treatment, but it decreased the concentration of proline and antioxidant enzymes. The mutual effects indicated the different responses of cultivars to the levels of biofertilizer in different drought stress treatments. In general, the Chamran variety is recommended by combining mycorrhiza with Azotobacter or Azespirillum.
