Abstract

In trials initiated in 2002, strawberry buds were removed at the beginning of flowering period to simulate the effect of an attack by the strawberry blossom weevil (Anthonomus rubi) on yield and berry size. The treatments comprised 4 levels of bud removal, 0, 10-15, 20-30 and 40-50%, involving one-year-old 'Honeoye' in Sweden, one-year-old 'Honeoye' and 3-year-old Zephyr in Norway and one-year-old cold-stored and strong cold-stored 'Elsanta' in Germany. The effect of removing buds of different order (primary, secondary and tertiary) was studied in cold-stored plants of 'Polka' in Finland. Bud losses of 10% or more early in the flowering period, which resulted in the loss of the biggest berries, reduced the yield, because the fruit size did not compensate this loss and increased only a little or not at all. Losses of buds at the end of the flowering period, which resulted in small fruits, were of minor importance because these will only be a small part of the whole yield
