Pit hardening period is the phenological stage when water stress is recommended in regulated deficit irrigation (RDI) in olive trees. In table olive trees, fruit growth is a very important process which could affect the final profit of the yield. RDI scheduling based on water status measurements...

Trunk diameter fluctuation parameters have been common indicators in water relations experiments. In most fruit trees, these parameters have been reported as very sensitive to drought conditions. However, the great variability of the measurements, amongst other factors, has limited their use in...

No information exits on the effects of water stress on pomegranate (Punica granatum L.) fruits. In this paper, the influence of three irrigation treatments on the physical and chemical characteristics of the fruits of adult pomegranate trees was studied. Control (T0) plants were drip irrigated...

The scarcity of water for agricultural use is producing a generalization of deficit irrigations in most of the fruit trees. Regulated deficit irrigation in olive trees is scheduled with a period of water stress during the pit hardening phase with low or, even, no decrease in yield. During this...

► This is a special issue related to the XI Spanish–Portuguese Symposium on Plant Water Relations. ► Main achievements of Spanish and Portuguese groups working on plant water relations are shown. ► This preface pays homage to Prof. Manuel Sánchez-Díaz. ► A brief description of the...

Maximum daily shrinkage (MDS) is the parameter of daily cycle of trunk diameter most widely suggested in irrigation scheduling for several fruit trees. However, as in other plant-measured approaches, the irrigation decision may be difficult due to the influence of the environment on the values...

The effects of high crop load (unthinned trees, 22-23 fruits cm-2 of trunk cross-sectional area (TCSA)), commercial crop load (3-4 fruits cm-2 of TCSA), and no crop load (all fruitlets removed) on maximum daily trunk shrinkage (MDS), trunk growth rate (TGR) and stem water potential ([Psi]stem)...

The use of trunk diameter fluctuations and their derived parameters for irrigation scheduling in woody crops is reviewed. The strengths and weaknesses of these continuously measured plant-based water stress indicators compared with other discretely measured indicators for diagnosing plant water...

Trunk diameter fluctuations (TDFs) have been suggested as an irrigation-scheduling tool for several fruit trees, but the works in olive trees has not obtained successful results with any of the indicators (maximum daily shrinkage (MDS) and trunk growth rate (TGR)) that are calculated from the...

The response of adult Fino lemon trees (Citrus limon L. Burm. fil.) on sour orange (Citrus aurantium L.) to an irrigation schedule based exclusively on maximum daily trunk shrinkage (MDS) measurements was studied during the 2005-2006 and 2006-2007 seasons. Plants irrigated above their crop water...
