AB  - Partial root-zone drying (PRD) technique, a novel approach to watering crops, was developed on the basis of knowledge of root-to-shoot signaling in drying soil. The aim of the present paper was to investigate the effects of the PRD treatment on tomato growth and the water regime. The obtained PRD results showed significant reduction in shoot but not fruit growth in the absence of any changes in shoot water status, indicating the involvement of chemical root-to-shoot signals. Higher water use efficiency (WUE) results mean that the PRD technique can be used to reduce irrigation water without significant reduction of tomato yield.
AB  - Tehnika delimičnog sušenja korenova (PRD), novi pristup u navodnjavanju biljaka, razvila se na osnovu saznanja o signalima suše na nivou koren-izdanak. Cilj rada je bio da se ispitaju efekti PRD tretmana na rastenje biljaka i vodni režim. Rezultati su pokazali da je PRD tretman izazvao značajnu redukciju rastenja izdanka, ali ne i plodova u odsustvu promene vodnog statusa izdanka što je indikator uticaja hemijskih signala na nivou koren-izdanak. Povećanje efikasnosti u korišćenju vode (WUE) je pokazalo da se primenom PRD tehnike može redukovati količina vode za navodnjavanje bez značajne redukcije prinosa paradajza.

AB  - Cilj ovih istraživanja je bio da se prouči uticaj različitih metoda navodnjavanja (regulisani deficit navodnjavanja (RDI), delimično sušenje korenova (PRD) i optimalno navodnjavanje (FI)) na prinos, efikasnost usvajanja vode i kvalitet plodova kod biljaka paradajza. Ispitivanja su obuhvatila merenje parametara prinosa (broj, prečnik, svežu i suvu masu plodova), efikasnost korišćenja vode (WUE), kao i parametre kvaliteta plodova (sadržaj šećera, organskih kiselina i likopena u plodovima). Dobijeni rezultati su pokazali da su metode delimičnog navodnjavanja korenova i regulisanog deficita navodnjavanja uticale na redukcije prinosa za oko 18% u odnosu na kontrolu. Takođe, ove metode navodnjavanja su uticale na povećanje efikasnosti korišćenja vode i redukovale su količinu vode za navodnjavanje za 40%. Delimično sušenje korenova i regulisani deficit navodnjavanja su poboljšali kvalitet plodova (posebno sadržaj šećera i organskih kiselina). Ovi rezultati su pokazali da se i po cenu manje redukcije prinosa može ostvariti kvalitetan prinos, a da se pri tome značajno uštedi voda za navodnjavanje.
AB  - The aim of the present study was to investigate the effects of different water supply conditions (regulated deficit irrigation - RDI, partial root drying - PRD and full irrigation - FI) on the yield, water use efficiency and fruit quality in tomato plants. Investigations included measurements of yield parameters (number of fruits, a fruit diameter, fruit FW and fruit DW), water use efficiency (WUE) and parameters of fruit quality (sugar, organic acid and lycopene content in fruits). Obtained results showed that partial root drying and regulated deficit irrigation reduced yield by18% comparing to control plants. Also, these methods of irrigation increased water use efficiency and reduced quantity of water for irrigation by 40%. Partial root drying and regulated deficit irrigation increased quality of fruit (especially sugar and organic acid content). These results showed that it was possible to increase fruit quality and to save water for irrigation without significant reduction of yield.

AB  - The effects of partial root-zone drying (PRD) and full irrigation (FI) techniques on tomato fruit growth and cell wall peroxidase activity in tomato exocarp were investigated in growth chamber conditions. The PRD treatment was 50% of water given to 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 15% to 20%. PRD treatment reduced fresh weight while having no significant effect on fruit dry weight. The activity of peroxidase was significantly higher in PRD treated plants compared to those of FI. Differences between FI and PRD were expressed on temporal basis. In the fruits of FI treated plants peroxidase activity began to increase shortly before the phase when in­tensive fruit growth started to decline with the peak of enzyme activity of 3.3 HRPEU g-1FW. The highest increase of peroxidase activity in PRD fruits coin­cided with the ripening phase and the peak of enzyme activity (5.95 HRPEU g-1FW) was measured at the end of fruit ripening. These data potentially identified different roles of tomato exocarp cell wall peroxidase in PRD treated plants. In FI treated plants a role of peroxidase in restricting fruit growth rate was confirmed, but the increase in enzyme activity during ripening of PRD treated fruit pointed out that cell wall peroxidase may also control fruit maturation by inducing more rapid process. .
AB  - U ovom radu ispitivan je efekat različitih tehnika navodnjavanja na rastenje ploda i na aktivnost peroksidaze ćelijskog zida u egzokarpu ploda paradajza. Ispitivane su tehnike delimičnog sušenja korenovog sistema (PRD) i optimalnog navodnjavanja (H) u uslovima gajenja paradajza u komori za gajenje biljaka. Pri primeni PRD tehnike supstrat u polovini korenovog sistema zalivan je sa 50% vode upotrebljene za zalivanje biljaka tretmatoom optimalnog navodnjavanja, dok je druga polovina korenovog sistema isušivana sve dok se sadržaj vode u supstratu nije spustio na 15% do 20%, kada je izvršena inverzija zalivanja. PRD tretman je izazvao samnjenje sveže mase ploda, dok je suva masa ploda ploda ostala nepromenjena. Aktivnost peroksidaze je bila značajno veća kod biljaka gajenih PRD tretmanom nego kod optimalno navodnjavanih biljaka. U egzokarpu plodova optimalno navodnjavanih biljaka aktivnost peroksidaze je rasla neposredno pre faze smanjenja intenzivnog rastenja dostižući maksimalnu vrednost od 3,3 HRPU. Kod PRD tretmana najintenzivniji porast peroksidazne aktivnosti u egzokarpu se vremenski poklapao sa fazom zrenja ploda. Maksimalna enzimska aktivnost od 5,95 HRPU je izmerena na kraju faze zrenja. Ovi podaci ukazuju na različite uloge peroksidaze ćelijskog zida u egzokarpu ploda kod PRD tretiranih biljaka. Kod optimalno navodnjavanih biljaka potvrđena je uloga peroksidaze ćelijskog zida u restrikciji rastenja plodova, a porast enzimske aktivnosti tokom faze zrenja u egzokarpu ploda PRD tretiranih biljaka ukazuje na mogućnost da peroksidaza ćelijskog zida indukujući brži proces učestvuje u kontroli sazrevanja ploda. .
