[Objective] The aim was to research drought resistance and adaptation mechanisms of Kaclsura coccinea under different drought stresses. [Method] The seedlings of Kadsura coccinea growing one year were taken as materials in order to investigate and analyze leaf SPAD value, relative water content （RWC）, malonaldehyde （MAD）, cell membrane permeability （RP）, proline （PRO） and superoxide dismutase activity （SOD）. [Result] As drought stress improved, leaf SPAD value and RWC were both diminishing and RWC fell remarkably; MAD, Pro, RP and SOD activity were increasing; MAD and RP grew significantly. [Conclusion] Kadsura coccinea is much sensitive to drought stress and will be affected if water loss is too much high.
