Abstract
‘Contender’ peach [Prunus persica (L.) Batsch] is being released to fulfill the need for a high-quality, consistent-cropping, yellow-fleshed freestone cultivar ripening between ‘Loring’ and ‘Elberta’.
Commercial postharvest handling systems were surveyed during two seasons to study handling methods on susceptibility of bell pepper fruit (Capsicum annuum L.) to bacterial soft rot (Erwinia carotovora subsp. carotovora). Fruit samples were taken from two field packers and one packing house in 1991 and two field packers and four packing houses in 1992. Numbers of injured fruits were classified as crushed, bruised, abraded or other. Fruits were inoculated with bacteria or left untreated then stored at 10 or 21° C. Fruit injury was less dependent on whether the operation was a packing house or a field packing line than on individual grower handling practices. In general, packing peppers in packing houses resulted in increased bruises while field packing increased abrasions. More open skin injuries, but not necessarily total injuries, resulted in more decay. In some situations, when chlorination was applied in packing lines, a reduction in rotted fruits from the field was observed.
Abstract
‘Derby’ peach [Prunus persica (L.) Batsch] was released in 1978 to fill the need for an early, large, fresh-market peach. Derby is the name of a town in the North Carolina sandhills.
Abstract
Effects of 8 peach seedling rootstocks on tree growth, survival, and fruit yield of ‘Redhaven’ and ‘Loring’ peach scion cultivars were tested in Alabama, Arkansas, Georgia, North Carolina, and South Carolina. Lovell seedling rootstock was a standard for comparison. Six years of data indicated that Siberian C was not an acceptable rootstock because tree survival and fruit yield were low. Halford was equivalent to Lovell for tree growth, fruit yield, and survival. Fruit size was unaffected by rootstock. Nemaguard and 2 North Carolina selections were resistant to root-knot nematodes (Meloidogyne spp.) but they were not resistant to ring nematodes [Criconemella xenoplax (Raski) Luc and Raski]. Soil fumigation improved tree survival in nematode-infested soil.
