| Abstract | ||||
| This study was conducted over two successive seasons (2021 and 2022) to investigate the effect of some plant growth regulators on the vegetative growth of Cleopatra mandarin rootstock seedlings (Citrus reshni L.). Thus, trials were conducted to evaluate the effect of foliar application of gibberellic acid (GA3) or kinetin (Kn) to promote their vegetative growth. Thus, the seedlings were subjected to spraying in April, June, August and October with GA3 (50, 100, 150 and 200 ppm) or kinetin (50, 75 and 100 ppm) as well as (control), to investigate their impact on some growth parameters. Data obtained during both experimental seasons revealed obviously that all GA3 and kinetin treatments increased significantly growth parameters as compared to control. However, concentrated solutions particularly GA3 at 200 ppm or kinetin at 100 ppm were statistically the most effective in this concern by significantly increasing seedlings height and stem diameter, in particular, in comparison to the control. | ||||
