| Abstract | ||
| The experiment was conducted throughout two successive seasons (2019 and 2020) in the nursery of Faculty of Agriculture, Cairo University, Giza to ascertain the impact of water salinity at various concentrations (control, 1000, 2000, 4000ppm), humic acid at various concentrations (0.2 and 0.4 g/l), and salicylic acid at various concentrations (300 and 450ppm) on the behavior of growth and blooming as well as the chemical components of Celosia argentea plant. The findings highlighted the fact that salinity at higher concentration (4000 ppm) reduced plant height, inflorescences number and flower density per plant and dry weight of vegetative growth. The content of total carotenoids, chlorophyll a and b, as well as total carbohydrates reduced in the dried leaves. Sodium, chlorine, and proline concentrations were increased when plants were exposed to higher salinity levels. Salicylic acid and humic acid, however, markedly decreased all evaluated features content of Na, Cl and proline. It is mostly preferred to use salicylic acid. Spraying salicylic acid could improve growth and flowering parameters and reducing the effects of salt. It can be advised to utilize salicylic acid at 450ppm based on the aforementioned findings. | ||
