range of evergreen plant species, including native Vaccinium species. Since the alternate host is not present in the southeastern states, further investigation is needed to identify the inoculum source in this area. Several southern highbush cultivars
Vaccinium species in crosses to incorporate genes for adaptation; however, little is known about Neofusicoccum species identification and the responses of native Vaccinium species to infection. Morphological differentiation between different species of
Softwood terminal cuttings of ‘Woodard’ and ‘Tifblue’ blueberry (Vaccinium ashei Reade) rooted best in media containing milled pine bark alone or mixed with equal parts of perlite, compared to sphagnum peatmoss alone or mixed with equal parts of perlite. Percentage rooting, root quality, and percentage marketability of softwood terminal cuttings of Vaccinium ‘Tifton 275’, a complex hybrid of V. corymbosum L. and V. ashei, was unaffected by rooting medium.
Rate of pollen tube growth in styles of cross-pollinated rabbiteye (Vaccinium ashei Reade) and tetraploid highbush blueberries were adequate to induce a commercial fruit set when pollinated up to 6 days after emasculation. Varying intervals between emasculation and pollination, up to 6 days, did not consistently influence percentage fruit set and number of seeds produced per fruit.
Worldwide production of highbush blueberry ( Vaccinium sp.) has increased tremendously in recent years, from ≈42,000 ha in 2005 to over 109,000 ha in 2014 ( Brazelton, 2016 ). This rapid growth is driven by strong consumer demand for the fruit and
Soil salinity is becoming an increasing problem for production of blueberry ( Vaccinium section Cyanococcus ), particularly in arid and semiarid regions. Under such conditions, salts, which can originate from soil parent material (weathered

Vaccinium arboreum (sparkleberry; section Batodendron ) is a widespread and abundant diploid blueberry species native in the southeastern United States ( Stockton, 1976 ; Vander Kloet, 1988 ). It flowers in April in north Florida and produces
, such as blueberries ( Vaccinium spp. section cyanococcus). Development of cultivars and practices that reduce dependence on these inputs requires a better understanding of the processes that affect rhizosphere pH. Some herbaceous and woody plants can
