“…On the other hand, in fruit trees such as pears, apples, cherries, peaches, and nectarines, Ψ stem values below −2.0 MPa are considered severe water stress and are undesirable as they will have a negative effect on current year fruit quality or yield or fruit quality the next year [45]. In pear trees, values below −1.1 MPa indicate water deficit conditions [46], values below −2.8 MPa induce cropping deficiencies the next year [47], and −3.5 MPa was suggested as the threshold value for vascular embolisms to develop [48]. Ψ stem values reported here (Figure 2) were more negative than those reported in deficit irrigation experiments in pear trees under tropical climates [49] but similar to those reported under Mediterranean [50] and Oceanic climates [51].…”

Stem water potential (Ψstem) is considered to be the standard measure of plant water status. However, it is measured with the pressure chamber (PC), an equipment that can neither provide continuous information nor be automated, limiting its use. Recent developments of microtensiometers (MT; FloraPulse sensors), which can continuously measure water tension in woody tissue of the trunk of the tree, can potentially highlight the dynamic nature of plant water relations. Thus, this study aimed to validate and assess the usefulness of the MT by comparing the Ψstem provided by MT with those same measurements from the PC. Here, two irrigation treatments (a control and a deficit treatment) were applied in a pear (Pyrus communis L.) orchard in Washington State (USA) to capture the full range of water potentials in this environment. Discrete measurements of leaf gas exchange, canopy temperature and Ψstem measured with PC and MT were made every two hours for four days from dawn to sunset. There were strong linear relationships between the Ψstem-MT and Ψstem-PC (R2 > 0.8) and with vapor pressure deficit (R2 > 0.7). However, Ψstem-MT was more variable and lower than Ψstem-PC when Ψstem-MT was below −1.5 MPa, especially during the evening. Minimum Ψstem-MT occurred later in the afternoon compared to Ψstem-PC. Ψstem showed similar sensitivity and coefficients of variation for both PC and MT acquired data. Overall, the promising results achieved indicated the potential for MT to be used to continuously assess tree water status.

“…Any deficit irrigation must be applied with caution as severe water stress during post-harvest could have a detrimental effect on yield and fruit disorders in the following year, as reported for peach (Girona et al, 2003(Girona et al, , 2005Naor et al, 2005;, apricot (Ruiz-Sanchez et al, 1999;Torrecillas et al, 2000) and almond (Goldhamer and Viveros, 2000;Marsal et al, 2008). The decrease in yield caused by severe postharvest water stress in the previous year has been attributed to lower fruit set (Ruiz-Sanchez et al, 1999;Goldhamer and Viveros, 2000;Torrecillas et al, 2000;Girona et al, 2003;Naor et al, 2006) due to lower pollen viability (Ruiz-Sanchez et al, 1999) and lower winter starch reserves . In contrast, a moderate level of post-harvest water stress did not affect final fruit size, fruit number per tree or yield in peaches (Larson et al, 1988;Johnson et al, 1992;Girona et al, 2005).…”

“…In early maturing cultivars the period between fruit set and harvest is short, with a rapid and continuous fruit growth in which it is difficult to identify growth stages. However, the post-harvest period is long and may therefore be a more suitable period for irrigation restriction (Johnson et al, 1994;Naor et al, 2006;Marsal et al, 2010), offering the opportunity to reduce vegetative growth and save water without interfering with fruit growth in the current season (Chalmers et al, 1981;Behboudian and Mills, 1997;Naor, 2006;Fereres and Soriano, 2007). Any deficit irrigation must be applied with caution as severe water stress during post-harvest could have a detrimental effect on yield and fruit disorders in the following year, as reported for peach (Girona et al, 2003(Girona et al, , 2005Naor et al, 2005;, apricot (Ruiz-Sanchez et al, 1999;Torrecillas et al, 2000) and almond (Goldhamer and Viveros, 2000;Marsal et al, 2008).…”

“…For early maturing fruit crops, such as peach, the postharvest period is usually preferred for applying DI because it provides the opportunity to save more water than in the preharvest period, without interfering with fruit development (Naor et al, 2006; Marsal et al, 2009). For instance, peach postharvest RDI increased fruit soluble solid concentration in the following season (Gelly et al, 2003).…”

Deficit irrigation strategies are considered as promising irrigation management for water saving. In the arid areas of southern Tunisia, agriculture relies heavily on irrigation. With rainfall scarcity, valuable management of water requires efficient approaches. In this context, the effects of deficit irrigation (CDI) and partial root zone drying (PRD) on the vegetative and fruiting behaviour of an early maturing peach (Prunus persica cv. Flordastar) were investigated. Shoot and trunk growth, yield, and fruit size were evaluated during three successive years (2013–2015). In reference to full irrigation (FI) treatment, a 50% water restriction was applied using CDI and PRD. The results obtained showed that both strategies at 50% crop evapotranspiration induced a similar significant reduction of tree vigour mediated by shoot length, trunk cross‐sectional area, and pruning wood weight. Consequently, there was a significant yield loss of 25% following the continuous water restriction of 50% observed throughout the experimental period. However, these yield losses were offset by substantial water savings in the range of 48%–52% and a significant increase of agricultural water productivity. Hence, these techniques lead to significant water savings and vegetative and yield losses offset by a significant increase in water productivity.
