Abstract:: The effects of salt stress (0，0.2% and 0.4%) on the photosynthesis and photosynthetic pigment of one-year-old seedlings of two cultivars of apple(‘Hanfu’,‘Huahong’) were studied.The results showed that the salt stress resulted in changes of diurnal variation of photosynthetic properties，so that the overall decline in photosynthetic performance；the photosynthetic pigment contents of the two cultivar seedings decreased gradually with the increment of salt concentrations.It was indicated through the comprehensive analysis that photosynthetic capacity of the two cultivar seedings ordered as ‘Huahong’>‘Hanfu’.
