Effect of cane length on cold stored grape punch quality [electronic resource].

Includes references.

Pruning combination of (5 x 14 , 6 x 12 , 7 x 10 , 9 x 8) orr number of canes x number of fruitful buds on each cane) were tried to investigate their effects on fruit quailty of superior cultivar grape. Sampies of 18 to 20 grape crusters were picked from each pruning treatment in late may, from a farm at new desert rands (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 1st season have less decay than 2nd year (0.8 % after cold storage 1st year and 7.0 % at the same conditions, 2nd year) TS.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 TS.S percentage and higher acidity and treatments of 7 x 10 and 9 , 8 had higher TS.S and lesser acidity than long cane pruning.
