maximum flavor. Shelf life depends on the cultivar, harvest method, and field and storage conditions ( Duan et al., 2011 ; Sargent et al., 2006 ). The respiration rate for blueberry was reported to reach between 2.0–10 mg·kg −1 ·h −1 at 0 °C and 52–87 mg

Abstract

Juices from 2 cultivars of muscadine grapes (Vitis rotundifolio Michx.), ‘Noble’ (dark-skinned) and ‘Carlos’ (bronze-skinned), were mixed with juices of ‘Concord’ and ‘Niagara’ grapes, cranberry or apple. ‘Noble’ juice, combined with ‘Concord’ juice, resulted in the highest quality among the dark mixtures prepared. Also, the mixtures retained most color and flavor during a 12 month storage period. ‘Carlos’ juice rated higher in quality when blended with the light-colored juices of apple and ‘Niagara’ than with the dark colored juice. The light amber color was stable during a 12 month storage period, and the flavor and overall acceptance of the mixture were rated higher than for the others.

Abstract

The storage life of ‘Clementine’ mandarin (Citrus reticulata Blanco) and Poncirus trifoliata (L.) Raf. pollen was effectively extended in an oxygen-free atmosphere. ‘Clementine’ pollen held at 4°C enabled satisfactory germination (20%) up to 7 weeks; a similar rate of germination was maintained after 20 weeks by use of N atmosphere. By combining deepfreeze temperatures (−18°) with either N or CO2 atmosphere for pollen storage, a germination rate of 13% was maintained after 57 weeks. With Poncirus, lower germination rates were obtained (7-9% after 57 weeks), but results paralleled those obtained with ‘Clementine’ mandarin pollen. Poncirus pollen, stored in an oxygen-free atmosphere at −18° for one year, maintained its fertilizing capacity.

Abstract

Firmness of ‘Starkrimson Delicious’ and ‘Golden Delicious’ apples was not significantly different when tested at 0° and 20°C after 26 weeks of storage at 0°. The volume of bruises produced in these cultivars by mechanical impact injury increased with increasing temperature (0°, 10°, 20°, and 30°) when injured, and with increasing holding temperature (0°, 10°, 20°, and 30°) during bruise development.

Twenty-six strains of `Delicious' apple (Malus domestica Borkh.) were evaluated over several years for growth, yield, and fruit quality at harvest and after 6 months of storage. `August Red', `Rose Red', and `Sharp Red' had larger trunk cross-sectional area (TCSA) 3 and 18 years after planting compared to most other strains. `August Red' and `Starking' had larger TCSA and cumulative yield. `Apex,' `Improved Ryan Spur', `Silverspur', `Starkrimson', and `Wellspur' were also among strains with high cumulative yields and yield efficiencies. `Hardi-Brite Spur' and `Red King Oregon Spur' had moderately high yields and small TCSAs, thus, high yield efficiencies. `Atwood', `Hardispur', `Imperial', `Improved Ryanred', `Starkspur Supreme', and `Topred' had low cumulative yields. `Ace' and `Improved Ryanred' had low yield efficiencies. `Ace', `Imperial', `Red King Oregon Spur', `Rose Red', `Starking', and `Wellspur' had heavier fruit, while fruit weight in `August Red', `Hardispur', and `Starkrimson' was lighter than that in most other strains. `Redspur' and `Starkspur Supreme' had the largest length to diameter (L/D) ratios. `Early Red One' had a similar red skin color rating as `Rose Red.' The red skin color rating of `Early Red One' was significantly higher than that of all other strains. `Hi-Early', `Improved Ryanred', `Redspur', and `Starking' had the poorest skin color ratings. `Hardispur', `Nured Royal', `Silverspur', and `Starkrimson' had high soluble solids concentrations (SSCs) at harvest and after storage. `Early Red One', `Imperial', `Improved Ryan Spur', and `Red King Oregon Spur' had lower SSCs at harvest and after storage. Fruit of `Apex' and `Redspur' had relatively high firmness at harvest, while `Hardispur', `Silverspur', `Starkrimson', and `Starkspur Supreme' had firm fruit at harvest and after storage. `Hardi-Brite Spur' had the softest fruit after storage, and fruit from `Rose Red' had a lower firmness than most other strains at harvest and after storage. Considering cumulative yield, yield efficiency, or some quality parameters, `Apex', `Classic Red', `Improved Ryan Spur', `Red King Oregon Spur', `Silverspur', and `Wellspur' had satisfactory overall performance. Strains are also suggested for planting depending on the market situation and the demand for a particular quality factor. `Hardispur' and `Sturdeespur' (Miller) are not recommended for planting under climatic conditions similar to those of this experiment.
