| Abstract: |
| With the method of drought stress and water recovery simulated in greenhouse, 8 drought resistant indicators, including leaf relative water content (RWC), relative electrical conductivity (REC), chlorophyll content (Chl), malondialdehyde content (MDA), soluble sugar content (SSC), free pro
line accumulation (Pro), superoxide dismutase activity (SOD) and plant height (PH) were measured for 20 germplasms of Hordeum vulgare L., and the relationship between these indicators and drought resistance was determined by correlation analysis and cluster analysis, so as to evaluate the drought resistance of different germplasms. The results showed that the RWC was significantly and positive
ly correlated with the plant height, and the tested germplasms of Hordeum vulgare L. could be classified into three groups: in the high drought-resistance group, there were Longmai 1, Xinyin D5, Z126V004W, Xinyin D9, PREJTGE, SCARLETT, Z02751407, Jiuqi 12, Z127U016V and MAURITIA; in the medium drought-resistance group, there were J13-80, Xinyin D7, PASADENA, NCF-TIPPLE and Ganpi 6; and in
the low drought-resistance group, there were Heiyinrui, Z200V017W, Xinpi 12, BEATRIX and Z204V021W. |
