Abstract

Abstract: We investigated the effect of 30-day NaCl treatment on chlorophyll fluorescence variables, chlorophyll content and water potential in 4 legume seedlings, Amorpha fruticosa, Hedysarum scoparium, Caragana korshinskii and Alhagi sparsifolia, introduced in Tazhong Botanical Garden, Xinjiang, northwestern China. NaCl did not change chlorophyll fluorescence values, chlorophyll content, or leaf water potential in C. korshinskii and A. sparsifolia, but the results were opposite for A. fruticosa and H. scoparium. C. korshinskii and A. sparsifolia showed more stable photosynthetic and physiological characteristics than A. fruticosa and H. scoparium with NaCl. Leaf chlorophyll content and water potential were related in part to chlorophyll fluorescence values with 30-day NaCl treatment and may be used to indicate plant responses to NaCl.
