Abstract
Abstract Effects of 6-BA on development in the ‘Tristar’ strawberry ( Fragaria × ananas sa Duch.) were evaluated. Runnering was promoted within 16 days of an initial application of an aqueous solution containing 6-BA. The promotive effect was proportional to the concentration of 6-BA in solution; however, repeated 6-BA application suppressed runnering. Flower bud development was not strongly influenced by 6-BA, but relationships among yield components were altered. A compensatory relationship between berry number and weight diminished, and the concentration of mineral elements in leaves increased, suggesting an effect of 6-BA on nutrient mobility. A dual role for cytokinin during growth and development in strawberry is suggested. Cytokinin appears to promote runnering early in development, but prolonged, elevated cytokinin levels inhibit runnering. Chemical names used: 6-benzylaminopurine (6-BA).
