Vaccinium has not been quantified. Southern highbush blueberry, like all cultivated blueberry, is adapted to acidic soils ( Coville, 1910 ; Finn et al., 1993 ) and experiences iron deficiency when grown in higher pH soils ( Gough, 1997 ). On the other hand

Although several new southern highbush blueberry cultivars have been introduced, little is known about their shelflife quality. Five southern highbush cultivars and three advanced selections were harvested from plantings at Clarksville, Ark. and held at 5C, 95% RH for 21 days followed by 1 day at 20C. `Gulf Coast' fruit had the most and `A109' the least weight loss after storage (12% and 6%). `Gulf Coast' fruit were rated softest after storage, Anthocyanin content was highest in `Cape Fear' and lowest in `MS108' (142 and 57 abs. units/g FW, respectively). After storage, total anthocyanin content increased 60% in `Cape Fear' and `O'Neal' fruit. Fruit pH was higher in stored fruit but titratable acidity decreased only in `ONeal', `Sierra', and `G616' fruit. Results indicate that southern highbush blueberries cultivars show great variability in shelflife quality.

The southern highbush blueberry cultivars `Blueridge', `Cape Fear', `Georgiagem' and `O'Neal' were evaluated for their response to sawdust/woodchip mulch for five years at Clarksville, Arkansas on a Linker fine sandy loam soil. Mulched plants produced higher yields and larger plant volumes than non-mulched. Berry weight was similar for mulch treatment except for the first fruiting year. All cultivars responded to mulch, although `Blueridge' and 'Cape Fear' produced the higher yields. General response of these cultivars of southern highbush was similar to that of northern highbush in previous mulch studies in Arkansas.
