| Abstract | ||||
| The effects of soil salinization on the growth and chemical composition of Cordia myxa seedlings sprayed with the compound sodium nitrophenolate (CSN) were studied. In the current study, sodium chloride salt was mixed with potting media at rates of 0, 2000, 4000, and 6000 mg/kg soil. The seedlings were sprayed with CSN at 0, 5, and 10 mg/L. Growing seedlings exposed to salinity, especially at high concentrations, coincides with the decrease in various growth measurements including survival percentage, number of leaves per plant, leaf area, fresh and dry leaf weight, and chemical components. CSN treatment had a substantial effect on improving the growth aspects and various chemical components of C. myxa seedlings. Maximum measurements of the growth and chemical components such as chlorophylls a and b and carotenoids, N, P, and K percentages, and total phenolics were recorded when the plants were grown in soil exposed to salinity at a rate of 2000 mg NaCl/kg soil and sprayed at a rate of 10 mg/L CSN. In contrast, higher free proline content coincided with 6000 and 4000 mg NaCl/kg soil. It could be suggested that C. myxa trees can grow in moderately saline conditions, and to improve their growth, they are sprayed with CSN at a rate of either 5 or 10 ml/l. Our findings support the future development of efficient growth methods for C. myx. | ||||
