| Abstract: |
| The drought-resistance of six varieties of Glycyrrhiza uralensis Fisch..accessions from different provenances 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 result showed that the relative elective conductivity and proline content would increase when soil relative water content descended.Root vigor and antioxidant activities would increase firstly, and then descend in the same condition.By subordinate function analysis, we could conclude that No.1 and No.2 accession from central region of Inner Mongolia have higher drought resistance, then followed by No.3 and No.4 from east region of Inner Mongolia.The resistance of No.5 and No.6 from Xinjiang was the lowest. |
