Sažetak
Common bean (Phaseolus vulgaris L.) is one of the most important legumes in the world and the lack of nitrogen in its cultivation can cause major negative changes leading to decrease in leaf protein content, such as RuBisCO, which causes a decrease in photosynthesis capacity and ultimately results in leaf damage and senescence. The aim of this study was to analyze the effect of nitrogen deficiency with ‘N-’ treatment, Hoagland solution with no added nitrogen, on the chlorophyll content index, ‘greenness’, digital biomass, quantum yield of photosystem II (Y (II)), maximum quantum yield of photosystem II (Fv/Fm) and the root system traits of Croatian common bean landraces ‘Trešnjevac’, ‘Zelenčec’ and ‘Biser’. Nitrogen deficiency treatment caused a decrease in the chlorophyll content index and ‘greenness’, digital biomass and changes in root architecture for all three landraces. The landrace ‘Zelenčec’ developed the largest root volume, and the landrace ‘Trešnjevac’ the largest average root diameter, digital biomass and highest chlorophyll content index in nitrogen treatment (N-).
