COLD STORAGE EFFECTS ON PERFORMANCE AND YIELD OF STRAWBERRY PLANTS
The effect of planting date and cold storage period at -2°C for 4, 6 and 8 months on plant growth, flowering, chemical constituents and flower bud development of Selva and Pajaro strawberry cultivars. Cold storage at -2°C before planting for day-neutral strawberry cultivars as Selva was not optimum since this temperature led to a low percentage of plant survival after cultivation. Therefore, if is not recommended to store the strawberry transplants of these cultivars using this temperature. However higher storage temperature, i.e., -1°C could be more appropriate. The anatomical studies indicated that ‘Selva’ plants differentiated flower buds earlier than those of ‘Pajaro’ plants. Generally, the increasing period of cold storage was negatively correlated with flower bud differentiation. A gradual decline in starch content of roots and crowns occured during the storage period. However, a gradual increase in sugar content was found. ‘Selva’ plants had more starch than ‘Pajaro’ while ‘Pajaro’ plants had more phenolic compounds than ‘Selva’. Early yield obtained from plants stored only 4 months at -2°C was higher than of those stored for 8 months, although plants stored for 8 months gave a higher total yield than those of 4 months cold storage.
