Effect of CPPU, GA3 and NAA on some quality parameters of Ruby Seedless grapes [electronic resource]. تأثير الCPPU وحمض الجبريليك ونفثالين حمض الخليك على بعض صفات الجودة لثمار العنب الروبى سيدلس. - p.551-563.

CPPU, GA3 and NAA were applied separately or in combination to bunches of Ruby Seedless grapes during two successive years ( 1998 and 1999). All concentrations of CPPU (2.5 & 5 ppm), GA3 (20 & 40 ppm) and NAA (2 & 4 ppm) reduced soluble solid content (SSC) and SSC/acid ratio significantly. The effect of CPPU in reducing SSC was more evident than GA3 and NAA in the first season, while in the second one the difference between them in this respect was little, Regarding titratable acidity content (TA), berries of all NAA and CPPU treatments contained higher TA than the control, while the effect of GA1 was not significant. Both CPPU and GA3 treatments increased cluster weight, berry firmness, berry length, berry diameter, receptacle diameter, pedicel diameter and berry removal force. The effect of NAA on cluster weight, receptacle diameter, berry removal force was not significant. Berry firmness of the NAA treatment was significantly lower than the unsprayed one.
Summary in Arabic.
Grapes--Quality.
Gibberellic acid.
Plant growth promoting substances.
