| Abstract:
The initial outdoor cultivation of kiwifruit (Actinidia deliciosa) began in British Columbia in 1985. After a successful growing season, an early freeze in November (-12 C) killed over 50 percent of the planted vines to the ground. A cooperative project, between the staff of Agriculture Canada, the B.C. Ministry of Agriculture and Fisheries (BCMAF) and the Ministry of Agriculture and Fisheries (MAF) in New Zealand, worked on methods for decreasing the plant vulnerability to this type of winter damage. During the winter of 1988, record low temperatures of -16 C to -18 C were recorded in some plantings in January. Even with these extreme temperatures, vines protected with trunk wraps suffered minimal damage and the plants grew normally in the following year. By 1989, there were 20 hectares of vines in commercial production and total fruit sales are expected to exceed 500 000 kg in 1990, all of which will be sold in Canada. | |
