The effects of partial rootzone drying (PRD), deficit irrigation (DI), and full irrigation (FI) on tomato physiology were investigated. In PRD and DI plants, leaf water potential values and stomatal conductance were significantly lower, while xylem ABA concentration was greater compared to FI plants. Photosynthesis was similar for all treatments. Water use efficiency was improved by PRD and DI, which reduced fruit dry weight, but had no effect on dry weight of leaves and stems.
U radu su istraživani efekti delimičnog sušenja korenova (PRD), deficita navodnjavanja (DI) i punog navodnjavanja (FI) na fiziologiju paradajza. Kod PRD i DI biljaka vodni potencijal listova i provodljivost stoma su bili značajno niži, dok je koncentracija ABA u ksilemu bila veća u poređenju sa FI biljkama. Fotosinteza je bila slična kod svih tretmana. PRD i DI tretmani su značajno povećali efikasnost korišćenja vode, redukovali su suvu masu plodova, ali nisu imali uticaja na suvu masu listova i stabla.
