“…It has been reported that chlorophyll content in maize was significantly reduced upon salinity, along with other plant traits including plant height, shoot/root biomass, and leaf numbers (Fatima et al, 2021;Mahmood et al, 2021). Likewise, similar patterns were obtained in potato plants in saline soil (Efimova et al, 2018). Hence, this implies that soil salinity tends to negatively affect crop growth and restrict nutrient uptake.…”

Abstract. Global sustainable agricultural systems are under threat, due to projected increases of co-occurring drought and salinity with climate change. Combined effects of drought and salinity on agricultural crops have traditionally been evaluated in small-scale experimental studies. As such the need exists for large scale studies that increase our understanding and assessment of the combined impacts in agricultural practice in real life scenarios. This study aims to provide a new approach to estimate and compare the impacts of drought, salinity and their combination on crop traits at large spatial (138.74 km2) and temporal extents in the Netherlands using remote sensing observations. Specifically, for both maize and potato, we calculated five functional traits from Sentinel-2 observations, namely: leaf area index (LAI), the fraction of absorbed photosynthetically active radiation (FAPAR), the fraction of vegetation cover (FVC), leaf chlorophyll content (Cab) and leaf water content (Cw). Individual and combined effects of the stresses on the seasonal dynamics in crop traits were determined using both one-way and two-way ANOVAs. We found that both stresses (individual and co-occurring) affected the functional traits of both crops significantly (with R2 ranging from 0.326 to 0.796), though with stronger sensitivities to drought than to salinity. While we found exacerbating effects within co-occurrent stresses, the impact-level depended strongly on the moment in the growing season. For both crops, LAI, FAPAR and FVC dropped the most under severe drought stress conditions. The patterns for Cab and Cw were more inhibited by co-occurring drought and salinity. Consequently, our study constitutes a way towards evaluating drought and salinity impacts in agriculture with the possibility of potential large-scale application for a sustainable food security.

Melatonin is among one of the promising agents able to protect agricultural plants from the adverse action of different stressors, including salinity. We aimed to investigate the effects of melatonin priming (0.1, 1.0 and 10 µM) on salt-stressed potato plants (125 mM NaCl), by studying the growth parameters, photochemical activity of photosystem II, water status, ion content and antioxidant system activity. Melatonin as a pleiotropic signaling molecule was found to decrease the negative effect of salt stress on stolon formation, tissue water content and ion status without a significant effect on the expression of Na+/H+-antiporter genes localized on the vacuolar (NHX1 to NHX3) and plasma membrane (SOS1). Melatonin effectively decreases the accumulation of lipid peroxidation products in potato leaves in the whole range of concentrations studied. A melatonin-induced dose-dependent increase in Fv/Fm together with a decrease in uncontrolled non-photochemical dissipation Y(NO) also indicates decreased oxidative damage. The observed protective ability of melatonin was unlikely due to its influence on antioxidant enzymes, since neither SOD nor peroxidase were activated by melatonin. Melatonin exerted positive effects on the accumulation of water-soluble low-molecular-weight antioxidants, proline and flavonoids, which could aid in decreasing oxidative stress. The most consistent positive effect was observed on the accumulation of carotenoids, which are well-known lipophilic antioxidants playing an important role in the protection of photosynthesis from oxidative damage. Finally, it is possible that melatonin accumulated during pretreatment could exert direct antioxidative effects due to the ROS scavenging activity of melatonin molecules.

P otato has been one of the major fresh staple vegetables consumed around the world for a long time followed by maize, wheat, and rice (Spooner et al., 2005). The production of potatoes in 2019 from an area of about 17.34 million ha was 370.43 million tonnes worldwide with the average yield of about Abstract | Potato is amongst the important staple starchy food throughout the world but its salt sensitive. A large portion of irrigated land in major countries is affected by salinity or is likely to be salinized in near future. This study assessed the impact of various salt levels on morphology and biochemical attributes of a wild (Sante wild) and two transgenic (Sante 2 event and Sante 8 event) potato varieties in in vitro condition. These varieties were grown on Murashige and Skoog (MS) media subjected to (0, 25, 50, 75 and 100 mM) of Sodium Chloride (NaCl). Potato varieties showed an adverse in vitro growth response to all levels of salt in MS media, while plants of all the tested varieties were dead at concentrations more than 50 mM of NaCl in in vitro condition (75, 100 mM). Variation was observed in the level of tolerance to salinity in these potato varieties. Increasing NaCl (mM) level reduced the overall plant growth, number of shoots, number of nodes and leaves, root and shoot lengths (cm), fresh as well as dry root and shoot weights (g). In contrast, proline, Na + and K + (mg g -1 FW) contents increased, while total chlorophyll (mg g -1 FW) content in all the variants reduced in salt stress. Overall, maximum salt tolerance was exhibited by Sante 8 event at (50 mM) in in vitro condition, as compared to other potato varieties. Furthermore, Sante 2 showed slight resistance to salt stress and Sante wild resulted in poor growth which makes it the most salt sensitive variety among tested varieties. Transgenic Sante varieties of potato having gene AtNHX1, showed significantly more resistance than wild variety.
