Water Uptake Threshold Of Rabbiteye (Vaccinium Ashei) Blueberries And Its Influence On Fruit Splitting, Donna A. Marshall-Shaw, James M. Spiers, Kenneth J. Curry

Faculty Publications

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 …
