This study evaluated the development of above and under ground parts of strawberry plants cvs. 'Fern' and 'Camarosa1 in a glasshouse using perlite, forest soil, finpeat, peat, finpeat+perlite (1:1) and peat+perlite (1:1) as substrates. The effects of different growing media on development of above and under ground parts of plant were statistically significant. The highest number of primary roots per plant, length of the most developed roots and number of crowns per runner were obtained from perlite, finpeat+perlite and peat medium, respectively, in both cultivars. The runner length, number of runners per plant, leaf area, fresh root weight and dry root weight varied between cultivars according to growth medium. In general peat, finpeat or finpeat+perlite gave the best results in terms of above and under ground parts of plants in both cultivars. Some important properties such as water retention capacity, cation exchangeable capacity, pH, porosity etc. of growing media using in this study were also determined.

Chloride and sodium are the main ions contributing to soil salinity in many regions but chloride is an essential element necessary for plant growth and development. It also controls the growth of some pathogens in plants. In this experiment, the effect of the chloride ion in nutrient solution on yield and fruit quality of two strawberry cultivars: 'Selva' and 'Camarosa' grown in hydroponic culture, was studied. Three kinds of nutrient solutions were used: 1) Hoagland-Arnon solution as control; 2) Hoagland-Arnon in which potassium nitrate was replaced with potassium chloride and ammonium nitrate was added as a nitrogen source and 3) the previous medium supplemented with 1.5 mmol l-1 magnesium chloride. Plant growth, total fruit yield, fruit firmness and leaf chlorophyll content were higher in plants grown in the second solution than the others, but there was no significant difference between the three solutions in terms of single fruit weight, soluble solids content and fruit dry weight. However, using 1.5 mmol l-1 magnesium chloride in a nutrient solution also increased the height of plants as well as total fruit production. The results showed that adding the chloride ion to the nutrient solution had no negative effects on fruit quality and leaf chlorophyll content.

The study was conducted in the 2007-2010 season, in the Pomological Orchard of the Research Institute of Pomology and Floriculture in Skierniewice, Poland. Under assessment was the productive value of 10 foreign strawberry cultivars: 'Camarosa', 'Gloria', 'Ventana', 'Albion' (USA), 'Susy', 'Vima Rina', 'Vima Xima', 'Elianny', 'Nancy' (the Netherlands) and 'Malling Pearl' (England). The standard cultivars were: 'Honeoye' and 'Elsanta'. The cultivars were evaluated in terms of fruit ripening time, marketable yield, fruit size and firmness, soluble solids and vitamin C content, the level of fruit infection by grey mould (Botrytis cinerea) and plant infection by leaf spot (Mycosphaerella fragariae), leaf scorch (Diplocarpon earliana) and powdery mildew (Sphaerotheca macularis). The studies revealed that the earliest to ripen were the fruits of the cultivar 'Ven­tana' and the last those of 'Vima Xima'. The most productive were: 'Elsanta', 'Vima Xima' and 'Nancy'. The largest fruits were produced by: 'Elianny', 'Camarosa', 'Vima Xima', 'Gloria' and 'Albion'. The fruits of the cultivars 'Albion', 'Gloria' and 'Vima Rina' were notable for the highest firmness. The highest amounts of soluble solids were found in the fruits of 'Elianny' and 'Malling Pearl'. The highest amounts of vitamin C were in 'Albion', 'Ventana' and 'Nancy'. Most of the cultivars were characterized by low infection of leaf spot, leaf scorch and powdery mildew. Moder­ately infected by leaf scorch were: 'Ventana' and 'Vima Xima', and by powdery mildew - 'Nancy'. Of all the evaluated cultivars the most useful for cultivation in central Poland is 'Vima Xima' because of its high productivity, high fruit quality and a ripening time that is later than in the other cultivars.
