| 摘 要： | 在不同浓度NaCl胁迫下,通过光合速率(Pn)、蒸腾速率(Tr)、气孔导度(Gs)、胞间CO2浓度(Ci)、叶绿素(Chl)、丙二醛(MDA)、游离脯氨酸(Pro)、超氧化物歧化酶(SOD)和过氧化氢酶(CAT)的测定,运用主成分分析法和模糊隶属函数法对30份国外引进的大麦Hordeumvulgare品种(系)耐盐性进行综合分析。结果表明:随着NaCl浓度增大,引进大麦品种(系)除SOD、CAT和Pro外,其他指标与对照相比均有所下降。根据综合评价值可知,其耐盐性由强到弱为:22-2522-30DH-116TabighaModaba22-55DH-5522-28TarpgolborKoRvKHEMUSSteptoeHarringtonClipperJrbidCpyrusDH-66PriorMorex22-43TObarleyBarbican22-42DH-40SchoonerDH-127KerabSloopYahudiyaDH-126。

| Abstract: | MDA content, SOD activity, CAT activity, Pro content and chlorophyll content, photosynthesis rate, stomatal conductance and transpiration rate were measured under different salt stress at seeding stage. Salt tolerance in 30 introduced materials of Hordeum vulgare was comprehensively analyzed by principal component analysis and subordinative function. The results showed that MDA content, chlorophyll content, photosynthesis rate, stomatal conductance and transpiration rate decreased with the increasing of NaCl concentration except SOD activity, CAT activity and Pro content. The sequence of salt tolerance for 30 materials was 22-25>22-30>DH-116>Tabigha>Modaba>22-55>DH-55>22-28>Tarpgolbor>KoRv>KHEMUS>Steptoe>Harrington>Clipper>Jrbid>Cpyrus>DH-66>Prior>Morex>22-43>TObarley>Barbican>22-42>DH-40>Schooner>DH-127>Kerab>Sloop>Yahudiya>DH-126. |
