Effect of anti-salts in the chemical properties of the pomelo seedlings leaves under salt stress

Abstract

The study was conducted in the district of  Al-Hilla, Al-Hakkana region for the period from 1\9\2020 till  1\5\202  in a fabric canopy to search the effect of anti-salts in the chemical properties of pomelo seedlings under salt stress by spraying the acids (salicylic, ascorbic, proline) at a concentration of 300 mg . L^{-1 in addition to the standard treatment (comparison) by irrigation four levels of saline water, which are (0,2,4,6 ds. M-1}) using sodium chloride salt, Chemical measurements were carried out(Nitrogen, phosphorous, potassium, iron, proline, chloride, sodium). The results showed the superiority of the treatment with salicylic acid at a concentration of (300) mg . L^{-1 in all the studied characteristics, and ascorbic acid at a concentration of (300) mg . L-1} had a significant superiority in the characteristics under study compared with the standard treatment.  The experiment was carried out by factor according to the Randomized Complete Block Design (R.C.B. D) and with three replications by three seedlings for the experimental unit with two factors (4 * 4). The number of experiment treatments was (16) treatments distributed randomly to (144) seedlings of one and a half years old, and the results were analyzed using an (ANOVA table) according to the EXCEL program. The statistical differences between the treatments were tested using the least significant difference LSD at a probability level (0.05).
