Technical Abstract: Different cultural systems - hill plasticulture and matted row, used on different strawberry cultivars and selections revealed that fruit from hill plasticulture were redder and greater in pigment intensity on the surface; and less red and less in pigment intensity in fruit flesh. There were no significant differences in the brightness (L* value) of fruit surface and flesh between the two cultural systems. In a cool growing season, the hill plasticulture cultural system also yielded a higher fruit soluble solid and ascorbic acid content, lower titratable acid (TA) content, and greater leaf area and chlorophyll content. In addition, the total sugar, fructose, glucose and myo-inositol contents were higher, but the sucrose content was lower in strawberry plants grown in hill plasticulture compared to those grown in matted row. The matted row cultural system resulted in fruits with greater malic acid, citric acid and ellagic acid contents, compared to those grown in hill plasticulture. In a warm season, the matted row system produced higher solid and sugar and lower acid contents than the hill culture system. Strawberry fruit surface and flesh color, soluble solid content, sugar, TA, ascorbic acid, organic acids, ellagic acid contents, leaf area, and chlorophyll content were all highly genotype dependent.
