Effects of exogenous Ca on stomatal traits, photosynthesis, and biomass of maize seedings under salt stress.

Understanding the responses of stomatal structure, photosynthesis and biomass of maize to exogenous Ca addition under NaCl stress has important significance for further uncovering the alleviative mechanism of exogenous Ca on maize under salt stress. We examined the effects of exogenous Ca(0, 5, 10, 20, 40, 80 mmol·L) on the stomatal structure, photosynthesis and biomass of maize (Zea mays L. cv.
