Changes in the levels of starch, sucrose and fructose in the roots of strawberry tray plants (cv. ‘Elsanta’) as affected by the duration of the gro wing period (8, 12, 18 or 20 weeks) were examined. Measurements of air temperature during the growing period were used to calculate cumulative chilling hours (<7 ̊ C). The largest accumulation of starch in the roots was found in the plants grown for 20 weeks , which was associated with the increased amount of chilling received by this group of plants (707 h). The lowest amount of starch was recorded in the roots of tray plants cultivated for 8 weeks (this group of plants had not been exposed to chilling temper atures at all). After storage ( - 1.5 to - 2 ̊ C in a cooling chamber) no starch and low concentrations of soluble carbohydrates (sucrose and fructose) were detected in the roots of the plants which had not been exposed to chilling (cultivated for 8 weeks). Als o, post - storage vigour and productivity were the lowest in this group of plants. There were no differences in fruit yield between the plants cultivated for 12, 18 or 20 weeks.
