Fruit development in artificially self- and cross-pollinated strawberries (Fragaria × ananassa) and raspberries (Rubus idaeus)

Abstract

Tunnel cultivation of berries is increasing on a global basis, and suitable management techniques are being studied for growing berry crops in a protected environment. Soil mulching and irrigation are among the techniques that significantly affect plant growth and yield. Tunnel cultivation is often limited to growing single cultivars, and little attention has been paid to the effects of growing several cultivars in the same tunnel. There are indications that crop yield and quality might benefit from cross-pollination. In this study, the effects of artificial self- and cross-pollination were studied in 15 strawberry and 6 red raspberry cultivars grown in a protected environment in a greenhouse. Four strawberry cultivars benefited from cross-pollination and one required it. In the case of raspberries, self- and cross-pollination had no effect on yield and fruit quality. In conclusion, particular berry cultivars are better suited to tunnel cultivation. © 2014 © 2014 Taylor & Francis.
