Abstract:
Abstract:The Calendula officinalis seedlings were used as experimental materials with the potting experiment.The effects of calcium chloride (CaCl2) with different concentrations (5,10,15, 20 mmol?L-1) on the changes of chlorophyll content，malondialdehyde (MDA) content，peroxidase (POD) activity，proline (Pro) content and leaf membrane permeability in pot seedlings of Calendula officinalis seedlings under 100 mmol?L-1 sodium chloride (NaCl) stress were studied,in order to explore the mitigation effects of calcium on the salt tolerance of Calendula officinalis seedlings.The results showed that the treatment T2 with 10 mmol?L-1 CaCl2 solution had the best alleviating effect on Calendula officinalis seedlings growth.The chlorophyll content increased by 13.43%，MDA content decreased by 34.72%，and POD activity increased by 42.69%.Pro content and relative conductivity decreased by 28.37% and 30.20% respectively.In conclusion，calcium can obviously alleviate the adverse effects of salt stress on the growth of Calendula officinalis seedlings，and 10 mmol?L-1 of CaCl2 solution had the best effect.
