“…Basic knowledge related to these aspects will allow the optimization of culture systems (environmental and agronomic conditions) and also may help to prevent some physiological disorders, such as the known as dry calyx. 19 This physiological disorder differs from salinity damage and its origin is unknown. For these reasons, the aim of the present work was to assess the influence of environmental, seasonal and genetic factors on nutritional and nutraceutical quality of strawberry fruits.…”

Three strawberry varieties cultivated in soilless systems were studied for their content of primary and secondary metabolites in relation to harvest time and crop conditions. The three varieties were chosen based on their sensitivity level to environmental stress: Palomar (very sensitive), Festival (sensitive), and Camarosa (resistant). Throughout the campaign, three samplings were performed: December (extra-early production), January, and March (early production). Differences among cultivars and harvest times were observed based on the contents of sugars, organic acids, phenolic compounds, and antioxidant capacity. The higher levels for total anthocyanins and flavan-3-ols were found in Camarosa and Festival strawberries, both in the January harvest. The Palomar variety showed higher total sugar/total organic acids ratio in the March harvest. The influence of cultivation practices and environmental conditions was assessed by nested ANOVA and PLS-DA. Differences in the sugar and phenolic content were observed depending upon variety and coverage type. TEAC was most influenced by the substrate type.

2 Leaf mineral content along the crop cycle may explain differences in response to fertilization among strawberry genotypes. A two year field experiment was conducted using responsive ('Camarosa', 'Ventana') and nonresponsive ('Camino Real', 'Candonga') to fertilization genotypes under proportional increases in nutrients supply: from a control dose "C" [120 kg nitrogen (N) ha −1 , 70 kg phosphorus pentoxide (P 2 O 5 ) ha −1 , 220 kg potassium oxide (K 2 O) ha −1 , 40 kg calcium oxide (CaO) ha −1 and 20 kg magnesium oxide (MgO) ha −1 ] to "1.33C" and "1.66C" in 2007 and to "1.5C" and "2C" in 2008. Response to fertilization was high (45-120%) at begining of harvesting and low (10-28%) at middle and end of harvesting. Correlation between leaf area and total yields was high (r ≈ 0.73) at begining of harvesting, except on 'Camino Real' (late and compact genotype). At begining of flowering and harvesting, responsive genotypes showed higher potassium (K) and lower calcium (Ca) leaf contents than nonresponsive genotypes, accentuated with the fertilization increase.
