| Abstract | ||
| This present work was carried out to investigate the effect of spraying Dormex (at 3%) at the end of Jan. and Sitofex at (5, 10, 15 and 20ppm) at full bloom and fruit set alone or combined with each other on time of bud burst, fruit set %, yield/tree and fruit quality of "Costata" kaki cultivar, planted in El–khadra area El-Bohira Governorate. The results can be summarized in the following points: 1- In both years of study, the date of bud burst of trees sprayed with Dormex (at 3%) was early (28//2/2007 and27/2/2008) than that of control trees (19/3/2007 and 21/3/2008), respectively. 2- Insignificant differences were detected between the two tested dates of spraying Sitofex at (5, 10,15and 20ppm) for all the studied parameters. 3- The best effects were obtained from trees sprayed with 20 ppm sitofex + dormex at 3% treatment, so it is recommended to obtain high fruit set percentage, fruit yield and to improve physical fruit properties i.e: weight size,length,diameter and firmness. On the other side,this treatment induced low TSS% ,high acidity% and tannins%, that means delaying the date of maturation which has great importance for postponing harvest date and increasing shelf-life period and storage ability. | ||
