“…No differences in yield between DI treatments were found, although the yield was lower than in fully irrigated trees (Tapia et al, 2009). PRD resulted in a lower reduction in root growth than the obtained with SDI with respect to the full irrigation treatment (Abrisqueta et al, 2008).…”

Water has become the most precious of natural resources in many areas of Spain and, since agriculture is the major consumer of water, improvements in water use efficiency are increasingly sought. Regulated deficit irrigation (RDI) is an irrigation strategy based on applying only a fraction of the plant water requirements during certain periods of plant development. The paper reviews the available information on RDI strategies, in woody tree crops and vines based on studies by Spanish research groups. Both the promising results obtained and the drawbacks are covered.

“…Apart from these, the minirhizotron technique, which uses a miniature video camera or a scanner to view and record root images through a transparent tube inserted in the soil, is less destructive than coring and enables time-course changes in root growth to be monitored (Upchurch & Ritchie, 1983;McMichael & Taylor, 1987;Smit et al, 2000;Hendricks et al, 2006). This methodology has been widely applied to the study of root dynamics in annual plants (Machado et al, 2003;Yang et al, 2003), forest trees (Day et al, 2006) and fruit trees (Fernández et al, 1992;Abrisqueta et al, 1994Abrisqueta et al, , 2008Wells et al, 2002;Bernier & Robitaille, 2004), as well as for measuring root production and mortality in several tree species (Comas et al, 2000;Crocker et al, 2003), but has been little used for evaluating the response to different crop management practices.…”

The objectives of the paper were to study the pattern of root growth (measured by minirhizotrons) in relation to trunk, fruit and shoot growth and the effects of crop load on tree growth and yield in peach trees. Two crop load (commercial and low) treatments were applied in a mature early-maturing peach tree orchard growing in Mediterranean conditions. Root growth dynamics were measured using minirhizotrons during one growing season. Shoot, trunk and fruit growth were also measured. At harvest, all fruits were weighed, counted and sized. Roots grew throughout the year but at lower rates during the active fruit growth phase. Root growth was asynchronous with shoot growth, while root and trunk growth rates were highest after harvest, when the canopy was big enough to allocate the photo-assimilates to organs that would ensure the following season's yield. Shoot and fruit growth was greater in the low crop load treatment and was accompanied by a non-significant increase in root growth. High level of fruit thinning decreased the current yield but the fruits were more marketable because of their greater size.Additional keywords: fruit growth; minirhizotrons; phenology; Prunus persica L.

“…This result was also reported by Giorio et al (1999) and Saei et al (2006). Closing of stomata, as a result of drought stress, has been attributed to increasing of the distribution of Abcisic Acid from root to leaves (Levy et al, 1978;Abrisqueta et al, 2008). Stomata closure in plants is an adaptation mechanism to water deficit, which causes water saving and protect plants against drought stress (Moriana et al, 2002).…”

Problem statement:The water deficiency is one of the serious problems, in the arid zones. Cycocel by increasing the stomata resistance and decreasing transpiration can help to water use efficiency. Approach: In this research the impacts of different doses of Cycocel (0, 500 and 1000 mg L ) and irrigation regimes (33, 66 and 100% of available water; referred to as I 1 , I 2 and I 3 , respectively) on some physiological parameters of three olive cultivars (Baghmalek, Fishami and Dezfuli) were investigated. The experiment design was factorial split in completely randomize. Measured parameters included fresh and dry weight of root and stem, root length, leaf area, Relative Water Content (RWC), stomata resistance and ratio of total fresh and dry weight of shoot to root. Results: Results showed that drought stress decreased stem fresh weight from 24 g for well Irrigated (I 1 ) compared to 17.5 g for drought stress treatment (I 3 ). Fishami cultivar indicated highest fresh and dry of stem (28.15 and 16.52 g), leaf (12.97 and 9.44 g) and root (25.34 and 7.99 g respectively) compared to other two cultivars. Olive plants in I 3 treatments had higher stomata resistance (46.05 sec cm . Conclusion: Results suggested that I 2 and cv. Fishami were superior compared to other irrigation treatments and cultivars. Cycocel adjusted drought neutralized negative effects of drought stress.
