“…In addition to the very high fruit‐splitting incidence in WS fruits, the marketable yield was lower than in FI plants due to the lower WS fruit size (Table ). In this sense, it is known that water deficit during pomegranate fruit growth and fruit ripening affects yield and fruit size . For this, these two phenological periods are considered as critical from the total yield point of view.…”

“…Zhu et al [4] demonstrated that with crop-pan coefficient increasing from 0.6 to 1.0, dry biomass of root, stem, and leaf was increased by 24.0%, 17.2%, and 22.8%, respectively. The enhancement of dry biomass as irrigation amount increased was primarily ascribed to the greater canopy and leaf area index [4], as well as increased assimilation rate under high irrigation level [33].

Soil respiration (Rs) is one of the major components controlling the carbon budget of terrestrial ecosystems. Aerated irrigation has been proven to increase Rs compared with the control, but the mechanisms of CO2 release remain poorly understood. The objective of this study was (1) to test the effects of irrigation, aeration, and their interaction on Rs, soil physical and biotic properties (soil water-filled pore space, temperature, bacteria, fungi, actinomycetes, microbial biomass carbon, cellulose activity, dehydrogenase activity, root morphology, and dry biomass of tomato), and (2) to assess how soil physical and biotic variables control Rs. Therefore, three irrigation levels were included (60%, 80%, and 100% of full irrigation). Each irrigation level contained aeration and control. A total of six treatments were included. The results showed that aeration significantly increased total root length, dry biomass of leaf, stem, and fruit compared with the control (p < 0.05). The positive effect of irrigation on dry biomass of leaf, fruit, and root was significant (p < 0.05). With respect to the control, greater Rs under aeration (averaging 6.2% increase) was mainly driven by soil water-filled pore space, soil bacteria, and soil fungi. The results of this study are helpful for understanding the mechanisms of soil CO2 release under aerated subsurface drip irrigation.

“…Then, when an important rainfall event takes place, previously water stressed pomegranate fruits are rehydrated asymmetrically because aril turgor increases to a much greater extent than peel turgor, the pressure of the arils on the peel favouring splitting. Intrigliolo et al (2013) estimated pomegranate evapotranspiration to be around 412-514 mm, but reports on the effect of irrigation management on pomegranate fruit yield and quality are relatively scarce. The first results indicated that it is possible to control the desired ripening time in pomegranates by applying different irrigation regimes (Sonawane and Desai, 1989).…”

“…On the other hand, Laribi et al (2013) showed that pomegranates from SDI trees, submitted to mild water stress during flowering and fruit set and more severe water stress during the linear stage of fruit growth and ripening, had a redder peel and higher level of total soluble solids in the juice. Intrigliolo et al (2013) and Laribi et al (2013) studied the pomegranate response to RDI involving irrigation water restrictions during different fruit stages and concluded that the period comprised by flowering and fruit set could be regarded as noncritical from the yield point of view and that irrigation water restriction during pomegranate fruit growth and ripening enhances peel redness and TSS in the juice. However, restricting the irrigation water during the linear fruit growth period increased the concentration of many bioactive compounds in the juice, such as anthocyanins, that are related to health and taste.…”

(2017) b s t r a c tWater scarcity in Mediterranean climate areas will be progressively aggravated by climate change, population increase and urban, tourism and industrial activities. To protect water resources and their integrity for future use and to improve biodiversity, besides following advanced deficit irrigation strategies in fruit cultivation, attention could well be directed towards what are at present underused plant materials able to withstand deficit irrigation with minimum impact on yield and fruit quality. To this end, the state of the art as regards deficit irrigation strategies and the response of some very interesting emerging fruit crops [jujube (Zizyphus jujuba Mill.), loquat (Eriobotrya japonica Lindl.), pistachio (Pistacia vera L.) and pomegranate (Punica granatum L.)] are reviewed. The strengths and weaknesses of deficit irrigation strategies and the mechanisms developed by these emerging fruit crops in the face of water stress are discussed. The response of these crops to deficit irrigation, with special attention paid to the effect on yield but also on fruit quality and health-related chemical compounds, was analysed in order to assess their suitability for saving water in Mediterranean semiarid agrosystems and to analyze their potential role as alternatives to currently cultivated fruit crops with higher water requirements. Finally, the factors involved in establishing an identity brand (hydroSOS) to protect fruits obtained under specific DI conditions are discussed.
