“…On the other hand, PAs spermidine (SPD), spermine (SPM), and putrescine (PUT) are small ubiquitous nitrogenous compounds that are reported to be involved in numerous plant growth and developmental process, and abiotic stress tolerance (Marcińska et al 2020;Farsaraei et al 2021;Hasan et al 2021;Mahdavian et al 2021). Numerous studies suggest that during various environmental stress conditions, the PA levels in plants tend to change with respect to content and structure thereby assisting plants to combat the stress by maintaining proper growth and development (Wu et al 2018;Jahan et al 2019).…”

Crop plants all over the world face an array of environmental threats among which drought is found to be the most deleterious. The present investigation was carried to test the efficacy of exogenously supplemented sodium nitroprusside (SNP), a nitric oxide donor, and polyamine (PA) putrescine (PUT) in mitigating the effects of polyethylene glycol (PEG)-imposed drought stress in in vitro grown seedlings of Solanum lycopersicum. PEG treatments at different concentrations (1, 2, 5, 10, and 15%) were assessed for their impact on plant growth parameters based on which 10% PEG was chosen as effective drought treatment. Varying concentrations of SNP (100, 150, and 200 µM) and PUT (0.1, 0.3, and 0.5 mM) at different combinations were studied for their mitigating effects. The results revealed that among the combinations tested, SNP (150 µM) + PUT (0.3 mM) resulted in effective mitigation of drought stress in S. lycopersicum seedlings. SNP and PUT supplementation enhanced the growth parameters such as shoot and root length and plant fresh weight (FW). Further, the relative water content (RWC), chlorophyll, and proline contents were significantly enhanced in the experimental plants as compared to the control. Effective reduction in the malondialdehyde (MDA) and hydrogen peroxide (H 2 O 2 ), a significant increase in the antioxidant enzymes, and the transcriptional level upregulation of antioxidant genes and drought-responsive genes were observed in the treated plants as compared to the control. These results suggest that exogenous supplementation of SNP and PUT has a positive influence on alleviating the drought stress in S. lycopersicum.

“…In the study carried out by Zeid (2004) on bean, germination rate increased with the external putrescine application under salty conditions. Likewise, in studies conducted in pepper (Koç et al, 2014), tomato (Mohamedsrajaden, 2019), fresh bean (Kibar et al, 2020) and pumpkin (Farsaraei et al, 2021), it was stated that salinity negatively affected germination and the harmful effects of salt stress on germination parameters can be reduced with putrescine application. Ekinci et al (2011) reported that the highest germination rate was obtained from 0.50 mM salicylic acid application in parsley, lettuce and carrot seeds, and 0.1 mM salicylic acid application in cabbage seeds, and that high doses of salicylic acid reduced the germination rate of seeds.…”

Objective: This study was conducted to determine the effects of putrescine and salicylic acid applications at different doses on germination, plant growth, quality properties and nutrient contents of lettuce under saline conditions. Materials and Methods: In the study, a total of 15 different applications using two different salt levels (100 and 200 mM), two different putrescine doses (0.5 and 1.0 mM) and two different salicylic acid doses (0.5 and 1.0 mM) were investigated. The effects of putrescine and salicylic acid separately and together with salt were examined. Results: According to the findings obtained from the research, it was detected that salinity negatively affected the germination, plant growth, quality properties and nutrient contents of lettuce. In general, it was determined that putrescine applications under saline conditions increased germination and plant growth parameters and significantly reduced the negative effects of salt stress. Furthermore, it was found that the 1.0 Put+200 NaCl application, in which salt and putrescine were used together, increased germination rate by 75.57%, plant height by 42.49%, plant fresh weight by 58.89% and number of marketable leaves by 43.20% compared to the 200 NaCl application.

“…Studies have revealed that increased antioxidant enzymes imply improved salt tolerance [ 69 , 70 , 71 ]. MDA is an important stress index in plants [ 72 , 73 , 74 ]. MDA content increases significantly under abiotic stress due to MDA being closely related to cellular membrane damage.…”

Cucumber (Cucumis sativus L.) is an important horticultural crop worldwide. Sodium (Na+) and chloride (Cl−) in the surface soil are the major limiting factors in coastal areas of Shandong Province in China. Therefore, to understand the mechanism used by cucumber to adapt to sodium chloride (NaCl), we analyzed the phenotypic and physiological indicators of eighteen cucumber germplasms after three days under 100 and 150 mM NaCl treatment. A cluster analysis revealed that eighteen germplasms could be divided into five groups based on their physiological indicators. The first three groups consisted of seven salt-tolerant and medium salt-tolerant germplasms, including HLT1128h, Zhenni, and MC2065. The two remaining groups consisted of five medium salt-sensitive germplasms, including DM26h and M1-2-h-10, and six salt-sensitive germplasms including M1XT and 228. A principal component analysis revealed that the trend of comprehensive scores was consistent with the segmental cluster analysis and survival rates of cucumber seedlings. Overall, the phenotype, comprehensive survival rate, cluster analysis, and principal component analysis revealed that the salt-tolerant and salt-sensitive germplasms were Zhenni, F11-15, MC2065, M1XT, M1-2-h-10, and DM26h. The results of this study will provide references to identify or screen salt-tolerant cucumber germplasms and lay a foundation for breeding salt-tolerant cucumber varieties.
