Abstract—The relationships among chlorophyll fluorescence and non-destructive, can be used as an ideal method to study
parameters, chloroplast antioxidant enzyme and active oxygen in the effects of environmental factors on plant photosynthesis
the leaves of P. tenuiflora seedlings under Na2CO3 stress was [4]. On the other hand, scientists studied active oxygen and
investigated in the article. Results showed that when Na2CO3 antioxidant enzymes of P. tenuiflora under salt stress at the
stress was less than %, the activity of antioxidant enzymes cellular level [5], but researches on antioxidant enzyme at the
(APX、GST、SOD) increased along with the increasing Na CO
2 3 subcellular level were few. In this article, the relationships
stress. However, the changes of actual photochemical efficiency of
among chlorophyll fluorescence ics of leaves, antioxidan
