AB  - The xylem hydraulic connection between shoot and fruits has previously been investigated, but contradictory conclusions were drawn about the presence of a flow resistance barrier in the pedicel. In this paper we were studying effect of the drought on the functional xylem vessels in the pedicels of tomato fruit. Commercial tomato genotype was grown in cabinet conditions under two watering regimes (full and deficit irrigation). An aqueous solution of eosin Y were used to visualize the path of water movement through tomato fruit pedicel and fluorescence microscopy observations were done on transversal and longitudinal sections. Dye uptake studies suggested that in well watered plants and in plants exposed to drought, a large majority of xylem vessels are not functional in water transport. Reduced-irrigation treatment significantly altered number and width of functional xylem elements in the fruit pedicel, especially in the abscission zone. This indicates that drought modifies xylem architecture and, thus, environmentally produced change in the hydraulic property of pedicel may affect fruit development.

AB  - Regulisani deficit navodnjavanja (regulated deficit irrigation - RDI) i delimično sušenje korena (partial root drying - PRD) su tehnike navodnjavanja koje se primenjuju u cilju uštede vode u poljoprivredi. Cilj ovog rada bio je da se ispita uticaj RDI i PRD na prinos plodova i anatomiju provodnog sistema u peteljci ploda na osnovu merenja površine ksilema i floema kao parametara od kojih zavisi hidraulična propustljivost i transport asimilata u toku rastenja i razvića ploda. Dobijeni rezultati ukazuju da je RDI značajno snizio prinos (veličinu i broj plodova), što je posledica redukovane površine ksilema i floema. Redukcija ksilema kod PRD biljaka postoji samo u ranim fazama razvoja plodova, što može dovesti do hidraulične i hemijske izolacije plodova, što se može smatrati adaptivnim odgovorom. Veća površina floema kod PRD biljaka je verovatno uticala na održanje prinosa.
AB  - Regulated deficit irrigation (RDI) and partial root drying (PRD) are irrigation techniques used to save water in agriculture. The aim of this study was to investigate the effect of RDI and PRD on fruit biomass and the anatomy of the vasculature system in the fruit pedicel based upon measurements of xylem and phloem areas as parameters determining hydraulic conductivity and assimilate transport during the fruit development. Data obtained point out that RDI significantly reduced yield (size and fruit number), as a consequence of reduced xylem and phloem areas. In PRD treated plants, the xylem was reduced only in the early developmental stages what could result in hydraulic and chemical isolations of the fruit, which can be considered an adaptive response. A larger phloem area in PRD plants most likely influenced yield maintenance.

AB  - The experiment was carried out to study the theoretical BACKGROUND:  of the effects of new deficit irrigation methods (regulated deficit irrigation -RDI and partial rootzone drying - PRD) on tomato plant and fruit growth. The RDI treatment was 50% of water given to fully irrigated (FI) plants and the PRD treatment was 50% of water of FI plants applied to one half of the root system while the other half dried down, with irrigation shifted when soil water content of the dry side decreased to ca. 20%. Plant and fruit growth parameters were measured as well as functional anatomy parameters (xy-lem and phloem areas in fruit pedicels). RDI significantly reduced plant and fruit growth, though PRD reduced shoot growth while having no significant effect on fruit growth. Anatomy data showed that PRD treatment increased phloem area and reduced xylem area in earlier stages of fruit development, although RDI reduced xylem area at the abscission zone in all phases of fruit development. This could lead to hydraulic and chemical isolation of fruits. Greater hydraulic isolation of PRD fruits from the rest of plant could be theoretical explanation why PRD treatment did not significantly influenced tomato fruit growth and yield.
AB  - Eksperiment je postavljen sa ciljem da ispita teorijsku osnovu efekata novih metoda deficita navodnjavanja (regulisanog deficita navodnjavanja - RDI i delimičnog sušenja korenova - PRD) na rastenje biljaka i plodova paradajza. Biljke izložene RDI tretmanu zalivane su sa 50% vode u poređenju sa optimalno navodnjavanim biljkama (FI). Kod biljaka izloženih PRD tretmanu polovina korenovog sistema zalivana je sa 50% vode, druga polovina korena nije zalivana, pri čemu je vršena inverzija strana kada se vlažnost supstrata u nezalivanoj strani spustila na oko 20%. Mereni su parametri rastenja biljaka i plodova kao i funkcionalna anatomija peteljke ploda (površine ksilema i floema). RDI tretman je značajno redukovao rastenje biljaka i plodova, dok je PRD tretman redukovao rastenje izdanka, ali nije imao značajan efekat na rastenje ploda. Anatomski rezultati pokazuju da je PRD tretman uticao na povećanje površine floema i redukciju površine ksilema u ranim fazama razvića ploda, dok je RDI tretman redukovao površinu ksilema u zoni abscisije u svim fazama razvića ploda. To bi mogao biti uzrok hidraulične i hemijske izolovanosti plodova. Veća hidraulična izolovanost PRD plodova od ostatka biljke može biti teorijsko objašnjenje zbog čega ovaj tretman nije značajno uticao na rastenje plodova paradajza a time i ostvareni prinos.
