“…Functional leaves of ginger were selected, and the Pn, Gs, Tr and Ci were measured by a portable photosynthesis system (Ciras-3, PP Systems, USA) using the method of Li et al (2013) , with slight modifications. When the Pn reached a steady state at each light intensity level, data were recorded 5 times per treatment, and the average value was calculated to determine the final photosynthesis parameters.…”

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.

“…Many studies on the photosynthesis and chlorophyll content of ginger have focused mainly on antibiotics and drought ( Li et al, 2013 ; Li et al, 2015b ; Liu et al, 2018 ). Salt stress was shown to decrease the growth and biomass yield (leaf fresh weight and root fresh weight) of ginger seedlings in a preliminary study.…”

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.
