Abstract BackgroundSalt stress is one of the abiotic stresses that affect plant growth, and it mainly reduces the biomass of plants by affecting their photosynthesis. However, little is known about the mechanisms by which low pH improves plant growth under salt stress. The effects of low pH on photosynthesis, chlorophyll fluorescence and mineral content in ginger (Zingiber officinale Roscoe) leaves under salt stress were investigated.ResultsIn this study, we found that the plant height and fresh weight, photosynthesis parameter (Pn, Gs, WUE and Tr), pigment concentration, fluorescence (qP, ΦPSII, Fv/Fm), Photosynthetic enzyme (fructose 1,6-diphosphatase (FBPase), ribulose-1,5-bisphosphate carboxylase (Rubisco), fructose 1,6-bisphosphate aldolase (FBA)), sugar metabolism and mineral content were significantly decreased under salt stress, but these parameters were all recovered by low pH. Meanwhile, low pH reduced the content of Na, while enhanced the content of K, Mg, Fe, Ca and Zn in ginger seedling leaves under salt stress. The observation of the ultrastructure of ginger seedlings under salt stress also showed that low pH can alleviate the damage of ginger seedlings to the complete structure and chloroplast.ConclusionsOur results suggested that low pH could enhance salt tolerance by improving photosynthetic efficiency and promoting absorption mineral.

Salinity is one of the main constraints for agriculture productivity worldwide. This important abiotic stress has worsened in the last 20 years due to the increase in water demands in arid and semi-arid areas. In this context, increasing tolerance of crop plants to salt stress is needed to guarantee future food supply to a growing population. This review compiles knowledge on the use of phytoprotectants of microbial origin (arbuscular mycorrhizal fungi and plant growth-promoting rhizobacteria), osmoprotectants, melatonin, phytohormones and antioxidant metabolism-related compounds as alleviators of salt stress in numerous plant species. Phytoprotectants are discussed in detail, including their nature, applicability, and role in the plant in terms of physiological and phenotype effects. As a result, increased crop yield and crop quality can be achieved, which in turn positively impact food security. Herein, efforts from academic and industrial sectors should focus on defining the treatment conditions and plant-phytoprotectant associations providing higher benefits.

We investigated the effects of low pH on the photosynthesis, chlorophyll fluorescence, and mineral contents of the leaves of ginger plants under salt stress. This experiment involved four treatments: T1 (pH 6, 0 salinity), T2 (pH 4, 0 salinity), T3 (pH 6, 100 mmol L−1 salinity) and T4 (pH 4, 100 mmol L−1 salinity). This study showed that photosynthesis (Pn, Gs, WUE and Tr) and chlorophyll fluorescence (qP, Φ PSII, and Fv/Fm) significantly decreased under salt stress; however, all the parameters of the ginger plants under the low-pH treatment and salt stress recovered. Moreover, low pH reduced the content of Na and enhanced the contents of K, Mg, Fe and Zn in the leaves of ginger plants under salt stress. Taken together, these results suggest that low pH improves photosynthesis efficiency and nutrient acquisition and reduces the absorption of Na, which could enhance the salt tolerance of ginger.

The aim of this experiment was to determine the responses of reed canary grass (Phalaris arundinacea L.) to salt stress during germination and vegetative growth. Therefore, effects of salinity (0, 50, 100,150, 200,250mMNaCl) on germination, changes in the percentage of germination, abnormal seedling and un-germinated seeds of two germplasms (Zxy06p-2449 and Zxy06p-2653) during germination under stress were determined. Moreover, during vegetative growth(40d old plants), changes in superoxide dismutase(SOD), peroxidase(POD), catalase (CAT), electrolyte leakage were also investigated after salt treatment for 5,10 and 15d. Salt stress decreased the germination percentage. Few seeds germinated at 200mMNaCl, abnormal seedlings and un-germinated seeds increased significantly under the higher salt concentration. During vegetative growth, increased activities of SOD, in 50,100 and 150mMNaCl treated-plants may help to avoid oxidative damage. Differential responses of antioxidant enzymes to salt stress during germination and vegetative growth suggested different antioxidant metabolism in reed canary grass. From the results obtained in present study, it can be suggested that reed canary grass is a moderately salt-tolerant specie with considerable germplasm differences. Zxy06p-2449 and Zxy06p-2653 will not be survive in long-term (>15d) salt treatment under 150mMNaCl, especially Zxy06p-2653 which shown more sensitive under higher salt concentrations
