Global warming brings a series of problems,
including the worsening of drought stress worldwide. This paper aims to find
optimal Calcium-using strategies in realistic events of drought stress. Maize
seedlings were grown in solutions with differing Ca2+ concentrations, and PEG6000 was
used to simulate drought stress. Several
physiological indexes were measured to determine the effect of Calcium ions on maize
seedlings under drought stress. Results show that a calcium concentration of 10mM yields best results under
both normal and drought conditions, but the lower calcium concentration of 2mM may be more favorable in
short-term drought stress situations.
