“…Although hand-harvest yields were similar in grafted and ownrooted blueberry grown in nonamended soils the first year, yields of grafted plants grown in nonamended soil were greater the 2nd year (2014) compared with own-rooted plants. This is likely due to the ability of V. arboreum rootstock to tolerate the low organic matter (Brooks and Lyrene, 1998) in the nonamended soils once the rootstock was established. Although V. arboreum rootstock use had a positive effect on yields in nonamended soils, the yields were lower than those of own-rooted plants in amended soils.…”

“…Vaccinium arboreum is a wild species native to the southeastern United States that exhibits a single-trunk growth habit (Brooks and Lyrene, 1998). If used as a rootstock for cultivated Vaccinium, the monopodial treelike architecture of V. arboreum could improve mechanical harvesting efficiency of blueberries.…”

“…A blueberry plant with a single trunk could eliminate much of the yield losses that occur with multicaned plants, as well as reduce the need to prune the bushes to fit the harvest machines. Along with the desired characteristics for mechanical harvesting, V. arboreum tolerates high pH (above 6.0) and low organic matter soils (below 2.0%) (Brooks and Lyrene, 1998), conditions that cultivated V. corymbosum tolerates poorly. Thus, it may be useful in reducing use of soil amendments that are necessary for successful blueberry production in many areas.…”

The profitability of the fresh market blueberry industry in many areas is constrained by the extensive use and cost of soil amendments, high labor requirements for hand harvesting, and the inefficiencies of mechanical harvesters. Vaccinium arboreum Marsh is a wild species that has wide soil adaptation and monopodial growth habit. It has the potential to be used as a blueberry rootstock, expanding blueberry production to marginal soil and improving the mechanical harvesting efficiency of cultivated blueberry. The objectives of this research were to compare yield, berry quality, and postharvest fruit storage of own-rooted vs. grafted southern highbush blueberry (SHB) cultivars (Farthing and Meadowlark) grown on amended vs. nonamended soil and either hand or mechanical harvested. Yields of hand-harvested SHB during the first two fruiting years were generally greater in own-rooted plants grown on amended soil compared with own-rooted plants on nonamended soil or grafted plants on either soil treatment. However, by the second fruiting year, hand-harvest yields of grafted SHB were ≈80% greater than own-rooted plants when grown in nonamended soil. Yields of mechanical-harvested SHB grafted on V. arboreum and grown in either soil treatment were similar to yields of mechanical-harvested own-rooted plants in amended soil the second fruiting year, and greater than yields of own-rooted plants in non-amended soil. In general, mechanical harvesting reduced marketable yield ≈40% compared with hand harvesting. However, grafted plants reduced ground losses during harvest by ≈35% compared with own-rooted plants for both cultivars. Mechanical-harvested berries had a greater total soluble solids:total titratable acidity ratio (TSS:TTA) than hand-harvested berries, and berries harvested toward the end of the harvest season had a greater TSS:TTA than those from early-season harvests. As postharvest storage time increased, berry appearance ratings decreased and berry softness and shriveling increased, particularly in mechanical-harvested compared with hand-harvested berries. Firmness of mechanical-harvested berries decreased during storage, whereas firmness of hand-harvested berries remained relatively stable. However, fruit quality at harvest and during postharvest storage was unaffected by V. arboreum rootstocks or lack of pine bark amendment. This study suggests that using V. arboreum as a rootstock in an alternative blueberry production system has the potential to decrease the use of soil amendments and increase mechanical harvesting efficiency.

“…It was possible to retain high vigor and fertility through multiple generations, and berry size was increased easily by selection. Several traits were improved by this method, including drought resistance, and corolla tubes with wider aperture (Brooks and Lyrene 1998a;Lyrene 1997).…”

Several characteristics from sparkleberry (V. arboreum) would be useful if transferred to highbush blueberry cultivars, but to date all direct crosses have failed. The purpose of this research was to see whether crosses of diploid V. darrowii and diploid V. fuscatum (both section Cyanococcus) with diploid V. arboreum (section Batodendron) could be made and to assess the possibility of transferring traits from V. arboreum into cultivated blueberries of section Cyanococcus. Many crosses were successful and easy to make. Crosses were more productive when V. arboreum was the pollen parent, but some hybrids were also obtained with V. arboreum as seed parent. Pollen stainability of F 1 (V. darrowii 9 V. arboreum) hybrids was low, ranging from 0.9 to 23.7%. Numerous meiotic abnormalities were found in the F 1 hybrids. These led to a high percentage of incomplete and unstained tetrads and probably to the production of unreduced gametes.
