| Abstract: | During the investigation of factors affecting fruit size in strawberry, the physical characteristics of the fruiting structure were examined as a possible cause of size limitation in fruit. The greatest total weight of fruit which can be sustained at any one time on an inflorescence appeared to be related to the dimensions of the main peduncle. At this limit the fruit yield may be no more than half the potential fruit yield of the inflorescence, indicating that unless ripe berries are removed development of immature berries may be restricted or stopped.This implies that under conventional management high yields will require frequent picking to achieve full potential. Once-over cropping, as in mechanical harvesting, may entail accepting yields one half or less of those now being obtained by conventional hand picking.It is suggested that if evaporative losses from ripe berries can be reduced, as by cloching, tunnelling, windbreaks, or plant breeding for less permeable cell walls, increased yields might be expected. |
