| Abstract | ||
| This study was carried out in a private orchard in badr district, Behera governorate – Egypt, using six years old own rooted "Crimson seedless" grapevines. to examine the influence of brassinoloids (Br) and lisophos either individually or in combination on berrie quality at harvest time. Crimson grapevines were treated by brassinoloids and Lisophos and sprayed twice at version (15-20%) coloration and ten days later in both seasons. The Br was used at (1 and 2 ppm) while the lisophos was sprayed at (100 or 200 ppm) in addition to the combinations between the concentration of both treatments. Thus, the total of nine treatments was applied including the control which was the surfactant. Tween 80 at (0.1% v/v) at harvest, each treatment resulted in Improving many fruit characteristics. However, the combined application of Br and lisophos showed more effective rather than individual application especially the combination of Br (at 1 ppm) plus lisophos at 200 ppm with certain fruit berry properties such as: carotene contents in berry skins and total anthocyanin in berry skin. In a similar manner the combination of Br ( at 2 ppm ) plus lisophos ( at 200 ppm ) resulted a, significant a increment in TSS to acidity ratio as compared to individual application Such trends were consistent in both seasons. Thus, a possible synergism exists between Br and Lisophos when sprayed on grape berries at veraison. | ||
