“…In general, an increase in NaCl concentration decreased PSII efficiency and photochemical quenching parameters and increased non-photochemical quenching parameters [9]. Throughout the experiment, the experimental controls showed an Fv/Fm of~0.82, consistent with a large number of other reports studying unstressed plants [24,41,42]. With the exception of a decrement for the highest NaCl concentration (400 mM) after the sixth day of treatment, Fv/Fm exhibited no significant difference between all NaCl concentrations over the experimental period ( Figure 2).…”

“…The highest and lowest reductions were observed in shoot fresh weight (~7 fold) and leaf width (~2 fold), respectively, relative to the control plants. A similar reduction in growth parameters under high NaCl concentration was also observed in a number of other plants, including lettuce [6,9,24,[33][34][35][36]. Qin et al [32] also found a significant reduction in lettuce fresh weight, grown under higher saline concentrations than controls.…”

“…CF analysis can detect small changes in photosynthetic activity and has been used as a powerful tool for studying plant stress response in a range of species [9,18,24,[38][39][40]. The present study showed that NaCl concentration affected CF parameters differentially, depending on the treatment schedule and NaCl concentrations (Table S1).…”

“…Similarly, Ouzounidou et al [36] found significant increase in proline concentration in broad bean grown under lower NaCl concentration. However, Shin et al [24] observed higher proline content only at NaCl concentrations above 200 mM in tomato seedlings, which suggests that the accumulation of proline under salt stress conditions is species dependent. The increase in proline content with the increase in NaCl concentration was probably due to the higher inhibitory rate of proline dehydrogenase and proline oxidase [53].…”

“…The CF parameters from the upper surface of all leaves on intact seedlings were obtained using an open FluorCam 800-O/1010 (Photon System Instruments, Drasow, Czech Republic), according to Shin et al [24]. Five seedlings (from the 25 uniform plants/treatment) were randomly selected and used to measure the CF parameters, which were independently measured at 0, 2, 4, 6, and 8 days after the initiation of NaCl concentrations treatment, after 4 h of light illumination.…”

Chlorophyll fluorescence (CF), growth parameters, phytochemical contents [proline, chlorophyll, ascorbic acid, total phenol content (TPC), total flavonoid content (TFC)], and antioxidant activities were investigated in lettuce (Lactuca sativa L.) seedlings grown under different sodium chloride (NaCl) concentrations (0, 50, 100, 200, 300, and 400 mM) in a controlled environment for eight days. The parameters were evaluated at two days intervals. Almost of the CF and growth parameters as well as phytochemicals were significantly affected by both NaCl concentrations and progressive treatment schedule. The maximum quantum yield (Fv/Fm), effective quantum yield of photochemical energy conversion in PSII [Y(PSII)], coefficient of photochemical quenching (qP), coefficient of non-photochemical quenching (qN), and ratio of fluorescence decline (Rfd) showed decrements only at the highest saline concentration (400 mM), whereas the quantum yield of non-regulated energy dissipation in PSII [Y(NO)] exhibited a dissipation trend. All the growth parameters decreased with increasing NaCl concentrations, showing the highest decrease (~8 fold) in shoot fresh weight, compared to control seedlings. Proline significantly increased with increasing NaCl concentration and treatment time. Other phytochemicals decreased with the increase in NaCl concentration and reached their lowest at 400 mM. Overall, the results showed major changes in all parameters when the seedlings were grown at a NaCl concentration of 400 mM. The present findings will be useful for understanding the differential effect of NaCl concentrations in lettuce seedlings, and also might be useful to optimize the NaCl concentrations in other crops grown in controlled environmental conditions.

Saline stress is responsible for significant reductions in the growth of plants, and it globally leads to limitations in the performance of crops, especially in drought-affected areas. However, a better understanding of the mechanisms involved in the resistance of plants to environmental stress can lead to a better plant breeding and selection of cultivars. Mint is one of the most important medicinal plants, and it has important properties for industry, and for the medicinal and pharmacy fields. The effects of salinity on the biochemical and enzymatic properties of 18 ecotypes of mint from six different species, that is,
