Comparison of Photosynthetic Pigment Contents and Antioxidase Activity of Anisodus tanguticus from Different Leaf Layers Grown at Two Altitudes Level in Qinghai-Tibet Plateau
Abstract:The four-year-old Anisodus tanguticus from two different altitudes(Xining and Haibei,altitude is 2 300 m and 3 200 m,respectively) was used to compare the physiological difference among different leaf layers.The results showed that leaf thickness was sign
