Technical Abstract: Tissue culture-propagated 'Chandler' plants were grown in a greenhouse to produce stolons. July-harvested plantlets were immediately stuck in cell packs and placed under mist sprinklers, or cold stored at 2ºC for 30 days in modified atmosphere environment (ambient or 3% CO2) and then plugged. All August-harvested plantlets were plugged immediately. The transplants were field planted at sites in Lake City, PA (latitude 42ºN and on Lake Erie) on 6 September and Carmichael, MD (latitude 39ºN and near Atlantic Ocean) on 12 September. Cold-stored plantlets developed fewer roots than plantlets plugged fresh. In the field, percent plant survival was reduced by cold storage treatments. Transplants that were produced from July-harvested plantlets and cold-stored developed more stolons in the field than fresh-plugged transplants. All transplants from July-harvested plantlets and rooted without cold treatment bloomed by November at the MD site, but not at PA site. Fruit production in MD ranged from 521 to 703 g/plant during a 4- week harvest in the spring, but was < 400 g/plant at the colder site in PA. Transplants generated from plantlets plugged in July produced 26% more fruit than plantlets plugged in August. Greenhouse soilless systems can be used to grow 'Chandler' stock plants for generating plantlets and transplants, but the transplants may not be suitable for annual plasticulture in colder climates. July-plugged 'Chandler' transplants have potential to produce a crop in late fall and high yields in the spring in areas with milder winter.
