Effect of Time After Harvest on Stem Scar Water Absorption in Tomato

摘要: Fresh market tomatoes (Solanum lycopersicum L.) handled through dump tanks and flumes at packinghouses can absorb water via stem scar tissues. This uptake lead to internalization of various hazardous bacteria, including Erwinia carotovora (Jones), the causal agent bacterial soft rot. Studies were conducted determine if interval between harvest immersion affected for 'Florida 47' 'Sebring', cultivars with high low uptake, respectively. Fruit held 2, 8, 14, 26 hours after fall season 4, 6, 14 following spring before immersion. Mature green fruit weighed, submerged in 2 min then reweighed uptake. During submergence, air pressure was applied such that exposed a static water-head equivalent 1.3 m. In 'Sebring' absorbed significantly less than 8 harvest. all times harvest, confirming results previous studies. season, time treatment did not affect either cultivar. By contrast, greater amounts as compared whereas similar 4-14 Therefore, minimize tendency water, packinghouse managers should hold freshly harvested least 4 immersing them tank.
