Pomegranate plasticity to water stress: attempt to understand interactions between cultivar, year and stress level.

This work investigated the effects of sustained deficit irrigation (SDI) on yield components and fruit physico-biochemical proprieties of two pomegranate cultivars, 'Sefri' and 'Wonderful' 21 trees each, in Sais plain (northern Morocco) over two consecutive seasons (2018-2019). Irrigation treatments consisted of a control, irrigation applied to fully satisfy crop evapotranspiration (100% ET), and two SDI treatments: 70% ET (SDI) and 50% ET (SDI). The effects of the SDI treatments differed between cultivars and years.
