Abstract

Vodni stres izazvan sušom predstavlja problem u uzgoju graha zrnaša, a njegov utjecaj očituje se promjenama u morfologiji, smanjenim prinosom i skraćenjem fenofaza. Rješenje problema ogleda se u odabiru otpornih sorata i primjenom novih tehnologija uzgoja poput predsjetvene bakterizacije. Istraživanje je provedeno 2018. godine u Poreču. Trofaktorijelni poljski pokus po split-split plot metodi u 4 ponavljanja uključivao je tretmane s i bez navodnjavanja, tretmane s i bez predsjetvene bakterizacije i 4 sorte niskog graha zrnaša. Promatrana su trajanja i pojava fenofaza, morfološka svojstva (visina biljke, broj listova, lisna površina), fiziološka svojstva (relativni sadržaj vode, sadržaj klorofila, vegetacijski indeks normalizirane razlike) i sastavnice prinosa. Pronađen je negativni učinak vodnog stresa na morfološka svojstva i razlike među sortama u morfologiji, kao i u vrijednostima relativnog sadržaja vode. Statistički opravdan učinak bakterizacije nije pronađen.

Abstract (english)

Water stress caused by drought is a problem in production of dry beans, and it can change morphology, decrease yield and shorten vegetation. Breeding of drought adapted cultivars and use of pre-sowing bacterization could enhance stress tolerance. The factorial field trial was set up in Poreč in 2018., as a split-split plot design in 4 replications consisting of treatments with and without irrigation, with and without bacterization on 4 cultivars of dwarf dry bean. The duration and occurrence of phenophases, morphological traits (plant height, number of leaves, leaf area), physiological traits (relative water content, chlorophyll content, normalized difference vegetation index) and yield components were observed. Negative impact of water stress was found on morphological traits, as well as differences between cultivars in terms of morphological traits and relative water content values. A statistically significant impact of bacterization was not found.
