Effect of Kinetin Pretreatment on Some Macroelements in Salt-Grown Bean (Vicia Faba L.) Plants

Abstract

The experiment was carried out using plastic pots during the growing season 2019-2020 to study the influence of seeds soaked in kinetin at 0, 50, and 100 mg.L-1 in faba beans (Vicia faba L.) grown under saline soil conditions was investigated with NaCl at 0, 50, and 100 mM and their interactions on some nutrients (N, P, K, Ca, Mg, Na, and Cl ) in vegetative part of faba bean plants. The experiment was designed according to a completely randomized design (CRD) with three replicates. The results showed that the nutrients N%, P%, K%, Ca%, and Mg% decreased significantly as the NaCl concentration increased, treatment with kinetin resulted in a significant increase with the above rates, especially under the effects of salt stress conditions, while an increase in the concentration of NaCl led to a significant increase in the percentages of Na and Cl. Soaking the seeds in kinetin led to a significant decrease in the percentages of Na and Cl compared with the control treatment. Results also showed a significant effect of the interaction between the two factors of the study and the concentration of 100 mg L-1 of the kinetin which gave the highest mean of nutrients percentage.
