Sažetak
Winter wheat can grow in different agroecological conditions, due to its morphological and physiological adaptation. The aim of this study was to examine the impact of fluctuations of temperature and precipitation regimes on winter wheat morphological (plant height, length of stalk, length of spike) and physiological properties (chlorophyll a, chlorophyll b, chlorophyll (a+b) and carotenoids). The research for winter wheat was been conducted at the North-eastern Croatia chernozem soil type in three different year. All morphological and physiological parameters (except chlorophyll b concentration) were under significant influence of climatic conditions in investigated years. All physiological and morphological parameters were highly significantly correlated with each other. Concentration of all chloroplast pigments were significantly correlated with plant height, length of stalk and length of spike. Very significant, positive correlations were observed between all physiological and morphological parameters of wheat with plant density and yield. Number of seeds per plant was significantly correlated with the concentration of chloroplast pigments and length of spike. The number of fertile spikelet in the spike was significantly correlated with all tested indicators except the number of sterile spikelet, which are significantly negatively correlated with the concentration of chloroplast pigments. In this study very significant correlation was determined between plant density in heading and yield.
