Abstract
‘Flordaprince’ is a low-chill requiring peach [Prunus persica (L.) Batsch] released for grower trial by the Florida Agricultural Experiment Stations in IFAS at the University of Florida. ‘Flordaprince’ bears attractive, large, high-quality, yellow-fleshed fruit (Fig. 1).
Two-year-old, container-grown rabbiteye (Vaccinium ashei Reade) and high-bush (Vaccinium corymbosum L.) blueberry plants were used in a 3-year study of water requirement for blueberry production in Florida. The rabbiteye cultivars Powderblue and Premier and the highbush cultivar Sharpblue were grown under three irrigation regimes. Irrigation events were triggered when soil water tensions in the upper 15 cm of the containers reached either 10, 15, or 20 kPa. Neither yield nor vegetative growth of rabbiteye cultivars differed among treatments. During the third year, the growth increase in highbush blueberry was significantly greater in the 10-kPa than in the 15- and 20-kPa treatments. The highest water treatment (10 kPa) resulted in a significant yield increase for the highbush cultivar.
Highbush (Vaccinium corvmbosum L.) rabbiteye (V. ashei Reade) and southern highbush (Vaccinium spp.) blueberries grown at seven locations in six southern states were sampled in 1988 and 1989 to determine foliar elemental levels among blueberry cultivars and types. Across locations, elemental levels of N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu and Al were similar for highbush and southern highbush types. Rabbiteye elemental levels were different from highbush and southern highbush for N, P, K, Ca, S, Mn, Cu and Al. The findings indicate that similar standard foliar levels can be used for highbush and southern highbush blueberries in determining nutritional status of plantings by foliar analysis. Rabbiteye blueberries appear to have different foliar levels, and may require species-specific standards for nutritional monitoring of plantings.
