Abstract:: The drought-resistance of Cymbidium lowianum of various media was studied under the conditions of artificial drought stress through measuring morphological indexes and physiological indexes related to drought resistance, and then valued integratively with subordinate function. The results showed that the relative elective conductivity would increase when soil relative water content descended. Malondialdehyde content,proline content and antioxidant activities would increase firstly and then descend in the same condition. By subordinate function analysis, M6 and M5 had higher drought resistance, the resistance of M1 and M4 was the lowest.
