ABA and yield-contributing traits: effect of ABA treatment on yield-contributing traits of the main shoot of 7AgL-carrier (HOM+) and non-carrier (HOM–) genotypes of (A) durum wheat NIRLs and (B) bread wheat T4 line; (C) endogenous ABA content in spikes at the boot stage and relative water content (RWC) of the corresponding flag leaf. FLW, flag leaf width; FL-1W, flag leaf-1 width; FL-1L, flag leaf-1 length, FLA, flag leaf area; FL-1A, flag leaf-1 area; EL1, ear length; SPNE1, spikelet number per ear; DW, dry weight.
