| Abstract | ||||
| Pruning combination of (5 x 14 , 6 x 12 , 7 x 10 , 9 x 8) or( number of canes x number of fruitful buds on each cane) were tried to investigate their effects on fruit quality of superior cultivar grape. Samples of 18 to 20 grape clusters were picked from each pruning treatment in late may, from a farm at new desert lands (Alex. Cairo desert road) in both seasons of 2001 and 2002. Half of the clusters were kept in ambient conditions (4 days) and the other half in cold store (0 °C for 5 weeks). The quality criteria were tested after the keeping period. Results obtained indicated that grape clusters of 1st year were less mature than 2nd year grapes despite. Grapes picking was at the same date. Also grapes on the 151 season have less decay than 2nd year (0.8 % after cold storage 1 st year and 7.0 % at the same conditions, 2nd year) T.S.S was generally higher in 2nd year juce than 1st year. Long cane pruning (5 x 14 and 6 x 12) had in general less T.S.S percentage and higher acidity and treatments of 7 x 10 and 9 '< 8 had higher T.S.S and lesser acidity than long cane pruning. | ||||
