摘要: The present studies aimed to investigate the effect of spraying with concentrations IAA and GA3 (0, 40 80 mg. L-1) interaction between them on Tiller Development Productivity relationship Yield Its Components for Wheat Oat in Muthanna province southern Iraq. cultivar (Ipa-95) (Wallaro) were planting 2013/2014 season. Experiments conducted R.C.B. Design three replicates. data indicated that increasing some studied characteristics (productive tillers number, grain weight, grain/ spike, weight (g) yield) related increased A.I.I while, total number tillers, surviving non productive decreased continuously during growth period, . used, has non-clear Straw (g). Grain yield GA3. (120 mg A.I.I. GA3.L1) gave highest averages 6.39 5.91ton. h-1 wheat crop respectively 5.93 5.92 ton. oat respectively. reason is increase one or more components grains per spike spike., harvest index also GA3.L-1) 42.55
