| Abstract:
A long cane production system was use in this study to manipulate the harvest season of raspberry cvs. ‘Chilliwack’ and ‘Tulameen’ in Ovalle, Chile. Canes of these two cultivars were collected in mid-winter from a raspberry field located in Los Angeles, a southern location, with a partial chill (230 hours) acquired in the field and then transported bare rooted to Ovalle, 800 km north for growth. Canes were treated with either 0 (T0), 200 (T1) or 300 (T2) extra chilling hours (CH) in a cold chamber and then planted in the field with or without a plastic tunnel. Bud break ranged from 37% in T0 to 48% in either T1 or T2. Yield per cane was affected by the cultivar and treatments. Higher yields were obtained in ‘Tulameen’ under T1 and plastic tunnel. Yield per cane varied among treatments and reach a maximum of 400 g per cane. Harvest date was advanced two to four week using tunnels compare to the open field, and more than five weeks compare to Los Angeles. According to our results ‘Chilliwack’ and ‘Tulameen’ require between 430 and 530 CH in this production system. | |
