Summary
This study investigates temporary salt stress via increased nutrient solution concentration during fruit production in soilless strawberry cultivation. Application of 120% temporary increase in nutrient solution concentration reduced yield in Camarosa (45.7%) and Gaviota (8.24%) cultivars, but significantly enhanced quality metrics including SSC/TA ratio and anthocyanin content, with cultivar-specific responses indicating differential salt tolerance between varieties.
Regional applicability
This research is directly applicable to protected cropping systems in the United Kingdom, where soilless strawberry production is widespread in commercial horticulture. The findings suggest targeted nutritional management strategies could improve soft fruit quality in UK glasshouse production, though cultivar selection and microclimate adaptation would require validation under UK growing conditions.
Key measures
Yield (%), soluble solid content/titrable acidity ratio (SSC/TA %), anthocyanin content (%), electrical conductivity of nutrient solution (% increase)
Outcomes reported
The study measured strawberry yield, soluble solid content/titrable acidity ratio (SSC/TA), and anthocyanin content in response to temporary increases in nutrient solution electrical conductivity. Quality metrics and cultivar-specific responses to salt stress were compared across control and treatment conditions.
