Six strawberry cultivars grown on the same commercial plantation in Brazil were evaluated for their chemical composition and quality attributes at the ripe stage. The profiles of the main soluble sugars, ascorbic acid, and anthocyanins were also obtained during the developmental stages. Results showed significant differences among cultivars in all of the investigated parameters. Cv. Campineiro ...

Our objective was to study the biology and develop a fertility life table for the aphid Chaetosiphon fragaefolli (Cockerell) (Hemiptera: Aphididae) on leaves of strawberry, Fragaria × ananassa, Duchesne ex Rozier (Rosales: Rosaceae), of the cultivars Albion, Aromas, Camarosa, Camino Real, Diamante, Earlibrite, and Saborosa. This study was conducted under controlled conditions: 25 ± 1 (°)C, 70 ±...

The study of chlorophyll fluorescence (CF) parameters i.e.: Fo, Fm, Fv/Fm, Y, qP, qN, F’o, F’m was conducted in two strawberry cultivars ‘Honeoye’ and ‘Teresa’. Measurements of their values were done twice: in an early autumn and late spring. Fluorescence of five dark-adapted mature leaves derived from each cultivar was measured in the laboratory at room temperature with the use of a portable p...

A major outbreak of virus-induced strawberry decline in western North America from 2001 onwards, led us to investigate whether the graft-transmissible agents reported in the crop are also involved in this recently observed symptomatology. Strawberries infected with virus-like agents maintained at the National Clonal Germplasm Repository in Corvallis, OR were studied for the presence of viruses....
