Changes of MDA in lithophytic bryophytes in different calcium environments. A The changes of MDA content of three lithophytic bryophytes cultured in different concentrations of Ca²⁺ solution for 7 days. B Changes in MDA content of three lithophytic bryophytes after 7 days of culture in Ca²⁺ 50 mmol/L solution. C Changes in MDA content of three lithophytic bryophytes after 7 days of culture in Ca²⁺ 100 mmol/L solution. D Changes in MDA content of three lithophytic bryophytes after 7 days of culture in Ca²⁺ 200 mmol/L solution. E Changes in MDA content of three lithophytic bryophytes after 7 days of culture in Ca²⁺ 400 mmol/L solution. F Changes in MDA content of three lithophytic bryophytes after 7 days of culture in Ca²⁺ 800 mmol/L solution
