Abstract:

Taking Rhododendron chrysanthum Pall.as material，the adaptation characteristic of leaves of Rhododendron chrysanthum Pall.populations at four altitudes (1 500，1 800，2 100，2 400 m) of Changbai Mountain were studied and compared.The results showed that leaf adaxial epidermal cells were looser with the altitudes increased and leaf lower epidermal cells were regular.Leaf dry matter content increased with altitude，and existed significant difference between low altitude and high altitude.SLA decreased with the altitudes.SLA of 1 800 m was lower than the other three altitudes.Leaf thickness increased with altitudes，and that of 1 800 m was thicker than the other three elevations.
