Abstract

Split-resistant and split-susceptible rabbiteye blueberry fruit were evaluated at all stages of development to determine ''water uptake thresholds'' by soaking in distilled water. Weight increase after soaking was measured, and percent weight gain was calculated to take into consideration the weight increase of the fruit from development. The ratio of percent increase in volume to weight increase resulting from water uptake was calculated. Ratios of percent water uptake to weight increase between splitsusceptible 'Tifblue' and split-resistant 'Premier' blueberries were found to be similar. The split-susceptible 'Tifblue' had a 1.6 g/50 fruit increase with a 1.7% water uptake and a ratio of 1.08. 'Premier' had a higher weight increase with 3.3 g/50 fruit and also a higher percentage of water uptake at 3.6% providing a ratio of 1.09. Although both absorbed water at a constant rate shown by a linear increase of weight increase over time, 'Premier' absorbed a significantly greater amount of water than did 'Tifblue' yet remained intact and did not split.
