摘      要：The effects of regulated deficit irrigation(RDI)on the performance of almond ***,peach ***-Hall and plum *** were assessed on the Saiss Plain(NW,Morocco)over three consecutive growing seasons(2011–2013).Irrigation treatments consisted of a control,irrigation applied to fully satisfy crop water requirements(100%ETC),and two RDI treatments,irrigation applied to 75%ETC(RDI-75)and 50%ETC(RDI-50).These three treatments were applied during fruitgrowth slowdown periods corresponding to Stages II and III in almond and Stage II in peach and *** and fruit quality traits were *** effect of RDI differed between *** and fruit size were reduced significantly only in peach under *** quality improved in this species in the first year of the experiment,with an increase of sugar/acid ratio and polyphenol *** quality also improved but the effects were significant only in the second and third *** results were recorded in almond kernel,but their epidermal grooves were deeper under RDI-50,and this may have affected their commercial *** is concluded that water can be saved during the fruitgrowth slowdown period by up to 25%in peach and 50%in almond and plum with improvements in fruit quality without affecting total yield.
