Abstract:
Planting local peanuts (Arachis hypogaea L.) treated with a spray with the amino acid putrescine during the 2021 agricultural season in the city of Jableh (Ain Shaqaq village) in Latakia Governorate. According to a randomized complete block design (RCBD) and in a one-time split arrangement with three replications, the main plots included spraying with saline solution at different concentrations, and the split plots included the number of irrigation times. This is for the peanut variety (local) that was treated with a spray with the amino acid polyamine, three times and with a time difference of 15 days between each time, with different concentrations of salt water, which are (0 – 2000 – 4000 – 8000 – 12000ppm). With the aim of studying the effect of spraying with polyamine and different concentrations of salt water starting from the flowering stage On some qualitative characteristics of peanuts. Salt concentrations, especially high ones (8000-12000 ppm), affected most of the qualitative traits studied and led to their general decrease, albeit insignificantly (phenols (1.96-2.02%), sugars (4.51-5.28%), protein ((20.67-21.66%), carotene (5.26%) -5.99 total chlorophyll (141.52-152.01 micrograms/g) and oil (46.87-46.92%, respectively. The amino acid putrescine also worked to reduce the stress of the salt solution and in some cases to increase the ability of peanut plants to tolerate salinity, especially with regard to the characteristics of the phenolic content. Sugars, protein and oil.
Keywords: peanuts, salt stress, amino acids, putrescine.
