2007
Monzon, M.E. | Biasi, B. | Mitcham, E.J. | Wang, S. | Tang, J. | Hallman, G.J.
The external and internal quality of 'Fuyu' persimmon fruit (Diospyros kaki L.) was evaluated after heating with radiofrequency (RF) energy to 48, 50, or 52 degrees C, holding at the target temperatures for durations ranging from 0.5 to 18 minutes, hydrocooling, and ripening at 20 degrees C for 12 days. These treatment conditions were identified for control of third instar Mexican fruit fly larvae (Anastrepha ludens). The treatments had no commercially significant effect on firmness, soluble solids content, titratable acidity, or weight loss of the fruit. RF-treated persimmon fruit attained a deeper orange-red skin color than control fruit. There was a greater incidence of slight to moderate flesh browning in fruit heated to 50 and 52 degrees C as compared with 48 degrees C. Calyx browning increased slightly in all RF-treated fruit and was the highest in the longer treatments at each temperature. Heating persimmon fruit with RF to 48 degrees C and then holding for 6 or 12 minutes showed the least damage, and the latter treatment was longer than should be required for a quarantine treatment against the third instar Mexican fruit fly. Holding persimmons for 6.6 minutes at 48 degrees C should provide control of the Mexican fruit fly and maintain fruit quality. Confirmation tests with infested fruit should be conducted.

2007
Hussein, M.A., Agricultural Research Corporation, Wad Medani (Sudan). Sennar Research Station
Three rates of organic wastes (SDH1) namely 6.18kg and 24 tree were added as mulch to mature guava trees, seven years old, grown at New Halfa Research Station to study their effects on growth, yield and fruit quality. Results showed that all organic wastes rate caused significant increase in tree heights compared to control, while stem diameters seemed to be unaffected. Significant increases in yield were noted comparing the treated trees with control and a higher yield observed at 16 kg/tree. Fruit quality measurement such as fruit diameter, fruit weight and fruit juice sugar contents tend to remain more or less constant and no significance was noted between the treated trees and the control

The influence of a verbal prompt on school lunch fruit consumption: a pilot study 全文
2007
Schwartz, Marlene B
BACKGROUND: This study evaluated an environmental intervention intended to increase consumption of the fruit serving among elementary school children participating in the National School Lunch Program (NSLP). METHODS: Children's fruit consumption was measured in two schools by observation. In the intervention school, cafeteria workers provided the verbal prompt, "Would you like fruit or juice with your lunch?" as the children stood in line in front of the fruit serving options. The control school had the same fruit and 100% juice options available, but the cafeteria workers did not provide a verbal prompt to take a fruit serving. Two variables were assessed: (1) Did children leave the lunch line with a fruit serving on their trays? and (2) Did they subsequently eat the fruit serving? RESULTS: The average percentage of children who took a fruit serving was 60% in the control school and 90% in the intervention school. In both schools, approximately 80% of children ate the fruit on their tray. As a result, nearly 70% of the children in the intervention school consumed a fruit serving at lunch, while fewer than 40% did so in the control school. CONCLUSION: A simple verbal prompt appears to have a significant impact on the likelihood that children will take, and subsequently consume, a fruit serving as part of their purchased school lunch. If these findings are replicated, policymakers may consider adding verbal prompts to the serving policy of the NSLP in an effort to increase fruit consumption among school children.

2007
Wedge, D.E. | Smith, B.J. | Quebedeaux, J.P. | Constantin, R.J.
Sixteen fungicide treatments were evaluated for control of strawberry fruit diseases in five fungicide studies conducted at Hammond, LA and Poplarville, MS during the 2002, 2003 and 2005 fruiting seasons. The most frequent fruit rots at harvest were anthracnose fruit rot caused by Colletotrichum acutatum, stem-end rot caused by Gnomonia comari, and Botrytis fruit rot caused by Botrytis cinerea. Fungicides from seven groups were shown to be effective for control of strawberry fruit rot diseases in these trials, and the commercial combination fungicides were often the most effective. In at least two trials when compared to the untreated control, total fruit rot was less on berries from the pyraclostrobin+boscalid, cyprodinil+fludioxonil, azoxystrobin, fenhexamid+captan, and captan treatments; anthracnose fruit rot was less on berries from the cyprodinil+fludioxonil and azoxystrobin treatments; and stem-end rot was less on berries from the cyprodinil+fludioxonil, pyraclostrobin+boscalid, captan, azoxystrobin, and pyraclostrobin treatments. While low in all trials, a significant reduction in Botrytis fruit rot incidence occurred in four trials. Berries from the cyprodinil+fludioxonil, fenhexamid, fenhexamid+captan, pyraclostrobin+boscalid, captan, pyrimethanil, and azoxystrobin treatments had the lowest incidence of Botrytis fruit rot. Efficacious fungicides from various FRAC groups will provide strawberry growers with more options for controlling diseases while managing fungicide resistance.
