Summary

External causes of poor fruit setting are spring frost during the flowering period; damage to flowers by parasites; unfavorable weather conditions during flowering; insufficient air circulation and insufficient pollination by bees under greenhouse conditions; insufficient pollination in overcrowded beds; and unfavorable soil structure. By good cultural practices many of these external factors can be eliminated. Sterility or incomplete fruit setting which is complicated and genetically controlled, is a more serious problem. Genetically, 2 types of strawberries can be distinguished The all-female which is heterozygous for the sex factor, and the more or less hermaphrodite-male type which is homozygous for that factor. In the latter group many intermediate forms are found between the all-male type with entirely sterile pistils and the almost entirely female type with very few stamens.
