Optimal exogenous calcium alleviates the damage of Snow-melting agent to Salix matsudana seedlings.

ABSTRACT: As the main component of snowmelt agents, NaCl is widely used in northern winters and significantly impacts the expected growth of garden plants in north China. Salix matsudana is also faced with salt stress caused by snowmelt, which seriously affects its development as the main tree species in the northern landscape. However, how exogenous calcium alleviates salt stress in Salix matsudana is not yet clear. In this study, the indicators of growth indices, photosynthetic characteristics and stress resistance were measured by hydroponic assays in combination with three NaCl conditions (0, 50 and 200 mmol·L^-1) and five calcium concentrations (0, 2.5, 5, 10 and 20 mmol·L^-1). The study's results indicated that the application of exogenous calcium remarkably p
