RELIABILITY OF RUSSIAN SEA BUCKTHORN CULTIVARS IN NORTH OSTROBOTHNIA, FINLAND
The cultivation area of sea buckthorn (Hippophae rhamnoides) has increased rapidly during recent years in Finland. One of the problems limiting cultivation is the lack of cultivars that are reliable under local cultivation conditions. Siberian cultivars were marketed in the early 1990s but did not become adapted to a maritime climate. The harvesting properties of Finnish cultivars are not suitable for commercial production. The reliability of five sea buckthorn cultivars from the Botanical Gardens of Moscow State University was studied at the North Ostrobothnia Research Station of MTT Agrifood Research Finland in 1997-2001. The cultivars studied were Avgustinka, Botanicheskaja, Botanicheskaja Ljubitelskaja, Gidrid Pertsika (synonym Hybrid Pertsika) and Trofimovskaja. Five plants per plot with 4 replicates were planted in June 1997. Two pollinators, also bred at the Botanical Gardens of Moscow State University, were planted in each replicate. The cultivars proved to be very susceptible to stem canker disease, which resulted in the death of shoots and entire bushes. The yields were negligible in 2000 and 2001.
