Under the condition of natural drought,the drought resistance of wild Cerasus humilis with different leaf types was investigated by measuring the relative water content,relative electrical conductivity,chlorophyll content,malondialdehyde(MDA)content,superoxide dismutase(SOD)activity and proline content of leaves of these two different leaf types.According to the membership function value of drought resistance index,the membership function value of wide-leaved wild Cerasus humilis at gully bottom was 0.43 and that of narrow-leaved wild Cerasus humilis at gully bottom was 0.58.The results showed that the drought resistance of narrow-leaved Cerasus humilis was obviously stronger than that of wide-leaved Cerasus humilis.The study on drought resistance of wild Cerasus humilis with different leaf types provided biological basis and basis for further germplasm resource selection and germplasm resource innovation of Cerasus humilis.
