| Abstract | ||||
| In order to evaluate the role of nano-micronutrients (at different rates: 0.0, 0.25, 0.50 and 1.00 g/l) on counteracting the harmful influence of soil salinity (at different levels: 0.0, 8000, 16000 and 24000 ppm) on growth, quality, salt tolerance trait percentage and total chlorophyll content of seashore paspalum, a pot experiment was conducted at Ornamental Nursery, Fac. Agric., Zagazig Univ., Egypt, during the two consecutive winter seasons of 2018/2019 and 2019/2020. The investigations were performed in a split-plot in complete randomized block design with three replications. Plastic pots in 40 cm diameter filled with 8 kg of sand and clay mixture (1:2, V/V) were utilized. Results referred to that using soil salinity at high level (24000 ppm) decreased growth characters (plant height, covering density %, herb fresh and dry weights per pot), root system (fresh and dry weights of roots/pot and root length), salt tolerance trait percentage and total chlorophyll content compared to control. While, proline content in leaves was increasing with increasing soil salinity levels to rich the highest values with 24000 and 16000 ppm, respectively. However, the highest values in abovementioned characters of (Paspalum vaginatum, Swartz) were noticed by nano-micronutrients at 0.50 and 1.00 g/l rates compared to control (sprayed by tap water) in both seasons. Generally, it could recommend that using 0.50 and 1.00 g/l of nano-micronutrients, showed a uniform effect in alleviating of seashore paspalum growth inhibition and its quality under low salinity stress (8000 ppm) condition with increasing in salt tolerance trait index. | ||||
