Yield fluctuations in cloudberry (Rubus chamaemorus)

Fruit yield in wild berry species can vary greatly from year to year. Despite the short growing season and low temperatures in the Arctic region, many small fruit species are thriving under such conditions. Cloudberry (Rubus chamaemorus L.) is a perennial dioecious plant dependent upon insects for pollination. Cloudberries are high-valued, but fruit set and yield can fluctuate substantially between years. Although most commercial harvesting of cloudberries is done from wild stands, a few commercial cultivars are available, and cultivation techniques for natural stands have been developed. There is limited knowledge of variations in cloudberry crops. Increased research on this topic can be crucial for enhancing our knowledge of cloudberry cultivation and having better predictions for increased commercial utilization.
