| Abstract | ||||
| This study was carried out during three seasons of 2008, 2009 and 2010 on Balady mandarin trees (Citrus reticulata, Blanco). This work was to evaluated the effect of some antioxidants namely ascorbic acid, salicylic acid and chelated zinc on yield and fruit quality of Balady mandarin fruits. The results reveled that sprayed mandarin trees with the three antioxidants increased the yield/tree than the control. Furthermore, lower concentration (500 ppm) of ascorbic acid, salicylic acid and chelated zinc gave a higher effect in this respect comparing with high concentration. The increment in yield /tree may be due to the increment in number of fruit/tree. Yet, these treatments resulted in somewhat effect on average fruit weight, SSC/acid ratio and vitamin C content in fruit juice. Furthermore, sprayed mandarin trees with ascorbic acid at 500 ppm produced higher content of soluble solid and vitamin C than the other treatments. The data indicated that spray 500 ppm of ascorbic acid, salicylic acid and chelated zinc at after fruit set and the one month later were beneficial to obtain economic yield with quality of Balady mandarin fruits. | ||||
