Abstract
Abstract Salinity is a significant and detrimental factor that limits the growth and development of plants. Although the individual responses of putrescine (Put) and salicylic acid (SA) are well reported depending on various abiotic stresses, their combined response under salinity stress remains largely unexplored. This study aimed to assess the impact of exogenous Put and SA on the germination, seedling growth, and biochemical properties of peas subjected to salinity stress. The research involved 15 different treatments with two dos of salt (100 and 200 mM), two Put concentrations (0.5 and 1 mM), and two SA concentrations (0.5 and 1 mM), evaluating the individual and combined effects of salt, Put, and SA. The results suggested that the germination, seedling development, and biochemical properties of peas were significantly responsed by salt stress, as well as by Put and SA applications. Salinity markedly decreased both germination and seedling growth. However, the use of Put and SA greatly mitigated the negative effects of salt stress, promoting the germination and seedling development of peas in salty conditions. Furthermore, the simultaneous application of 0.5 mM SA and 100 mM NaCl led to a 22.73% increase in germination rate, a 44.72% increase in seedling fresh weight, and a 21.84% increase in chlorophyll content, compared to the sole application of 100 mM NaCl. The research indicates that the exogenous treatment of Put and SA can mitigate the detrimental effects of salinity, thereby enhancing seedling development and germination in peas.
