This work presents new data on the effects of orchard growing factors on storage quality of Staccato sweet cherries grown in the southern Okanagan region of British Columbia, Canada. Quality attributes, respiration rates, and the mineral contents of Staccato sweet cherries were analyzed. Orchard growing factors such as pruning practices, growing temperature, and relative humidity varied by orchard throughout the region, and consequently, the mineral contents, quality attributes, and respiration rates of the Staccato sweet cherries also varied. Principal components analysis revealed relationships among orchard growing factors, cherry fruit mineral content, and fruit quality data. The content of Ca, Mg, N, P, and K in cherry fruit was correlated with quality attributes such as pitting, pebbling, soluble solids, titratable acidity, dry matter, firmness, and stem pull force. Orchard temperatures and relative humidity also influenced flavour quality attributes and appearance. Orchard management practices resulting in large leaf sizes were generally associated with good flavour quality and appearance. This work provides new data to support improved understanding how cherry quality is affected by orchard growing factors in an integrated analysis.
