Sarcocornia fruticosa photosynthetic response to short-term extreme temperature events in combination with optimal and sub-optimal salinity concentrations

Sarcocornia Fruticosa Recovery Capacity after Exposure to Co-Existed Water and Salinity Stress

“…The water state of S. fruticosa has been proven to be resistant to salinity presence in the growth solution (Redondo-Gómez et al 2006;Pérez-Romero et al, 2020a;Calone et al, 2022). Our results agreed with these previous studies showing a stable Ψ 0 independently of NaCl concentration.…”

“…Halophytes have the potential to be used as new crops in an innovative agriculture threshold due to their high biomass production, their nutritional values, and their ability to grow in extreme conditions (Ventura and Sagi 2013;Ventura et al, 2015;Pérez-Romero et al, 2018;Calone et al, 2022). There is abundant literature on the ability of halophytes to cope with stress (Redondo-Gómez et al 2006;Carreiras et al, 2020;Pérez-Romero et al, 2020a) or their phytoremediation potential (Pérez-Romero et al, 2016;Mateos-Naranjo et al, 2018;Barcia-Piedras et al, 2019). However, few studies can be found on recovery from abiotic stresses in halophytes species (Calone et al, 2022).…”

“…Nevertheless, plants grown at WW 3% R-WW-NaCl showed an improvement on A N and values similar to those grown at WW 1%. This could be related to a synergic effect of both types of stress, Pérez-Romero et al, 2018;2020a) demonstrated the importance of considering the synergic effect between abiotic factors in order to better understand the response of plant species in their natural habitat. This study reflected these complex relationships established between plants and their environment and showed how exposure to water stress in the presence of 510 mM NaCl may affect the ability of S. fruticosa to recover after the stress period.…”

“…On the other hand, it could be a mechanism to reduce damage due to excess energy dissipation through conversion of violaxanthin to zeaxanthin (Duarte et al, 2013). There has been evidence that halophytes that exhibit an increase in DES index values were able to respond better to abiotic stress (Pérez-Romero et al, 2018;2020a). Therefore, the increase in this parameter in S. fruticosa plants recovering from the stress period could indicate that these plants responded to water and salinity stress by dissipating excess energy, allowing them to restore their physiological status.…”

“…Furthermore, they have been proven as tools for soil phytoremediation (Pérez-Romero et al, 2016), carbon sequestration (Calone et al, 2022), and recovery of saline soils (Barcia-Piedras et al, 2019). Among them, Sarcocornia fruticosa has been tested in previous studies as a drought, salt, and heat waves resistant plant (Redondo-Gómez et al 2006;Pérez-Romero et al, 2020a;Calone et al, 2022).
