Sažetak
The study aimed at analysing the reaction of three strawberry (FragariaananassaDuch.) cultivars to the salinity (0-control, 0.5, 1.0, 2.0, 3.0 and 4.0 g of NaCl L-1 in the irrigation water: equivalent of the following ECiw values: 0.73, 1.65, 2.66, 4.37, 5.93 and 7.81 mS cm-1). Vegetation trial was carried out at the Faculty of Agriculture in Zagreb during two years. Following parameters were tested: yield of fruit (g/plant), number of fruits per plant, average mass of fruits, number of floral shoots, number of fruits per floral shoot and percentage of dry matter of fruits. Sodium chloride had a significant impact on the fruit yield: yield reduction was observed in cvs. 'Elsanta' and 'Marmolada' at 0, 5 g of NaCl L-1, while in cv. 'Miranda' at 2, 0 g of NaCl L-1. Average reduction of yield under the influence of salinity was the highest in cv. 'Elsanta' followed by cvs. 'Marmolada' and 'Miranda' (reduced number of fruits and average of fruit mass). Dry matter percentage of fruits was increased in all three cultivars when nutrient solution contained 1.0 - 3.0 g NaCl L-1. However, there was a significant reduction of dry matter percentage of fruits at the highest concentration of NaCl (4.0 g NaCl L-1) in cvs. 'Elsanta' and 'Marmolada', but not in cv. 'Miranda'. Drymatter percentage of fruits was significantly higher in cv. 'Miranda' then in cvs. 'Elsanta' and 'Marmolada'.
