| Abstract:
The effect of short-day treatments on yield and quality characteristics of six strawberry cultivars was investigated. Experiments were carried out during two seasons. In the first season, daylength shortening (DLS) treatments were applied during two application periods (15 September–l October and 1 October-15 October) with 3 cvs (Douglas, Vista and Tufts) were tested. In the second season, 3 application periods (21 September -8 October; 8 October-25 October, and 25 October-11 November) and 6 cvs (Douglas, Vista, Tufts, Cruz, Dana, Dorit) were tested. During the first season DLS treatments had no significant effect on yields in any of the cultivars. In the second season, DLS treatment during the third period gave significant yield increases in the cv. Dana, but fruit size decreased. Other, non-significant, increases in yield with DLS treatments were recorded with other cultivars. There were no significant effects of the DLS treatments on various fruit quality parameters. | |
