| Abstract | ||||
| Salinization is increasing on a global scale, and improving the tolerance of plants to salinity is urgent to study, so this study was conducted at the Department of Ornamental Horticulture, Faculty of Agriculture, Cairo University, Giza, Egypt during two successive seasons 2019 and 2020 to evaluate the effect of zinc sulfate and ZnO nanoparticles treatments as a foliar application at the level of 0, 20, and 40 ppm on some morphological and chemical features of Trigonella foenum-graecum plants grown under three salinity levels (0,1500, and 3000 ppm) aiming to reduce the negative effect of salinity on plant growth. The present study revealed that salinity stress caused a decrease in morphological traits (shoot length, number of branches/ plant, number of leaves/ plant, shoot fresh weight, shoot dry weight, root length, root fresh weight, and root dry weight) and harvest traits (number of pods/plant, number of seeds /pod, and 100 seed weight), as well as total phenols, and K+ /Na+ ratio. While, using zinc sulfate and ZnO nanoparticles gave high results with all studied morphological traits, and also improved the harvest characteristics of the fenugreek plants. The highest 100-seed weight and total saponins were obtained by the interaction between the treatments of ZnO nanoparticles at 40 ppm and salinity at 1500 ppm. According to the obtained results, it could be concluded that ZnO nanoparticles and zinc sulfate mitigated the negative effects at each level of salinity under this study. | ||||
