摘要
本文对左山一葡萄为母本,SO4为父本杂交的5个子代株系(A15、A17、A34、A35、A48)和左山一葡萄为母本,101-1为父本杂交的2个子代株系(B24、B26)的一年生扦插苗的抗旱性进行评价。以砧木1103P以及克瑞森葡萄为对照,杂交株系的盆栽土壤保持相对含水量为45%的中度干旱水平,对照盆栽保持土壤相对含水量为80%(各试材均设置未经水分胁迫的自身对照),以检测电导率、相对含水量、根系活力、叶片厚度、丙二醛、叶绿素、过氧化氢酶、过氧化物酶等相关抗旱指标,并对其抗旱能力初步评价及分级。结果表明:绝大部分杂交后代具有较强的抗旱能力,其中抗旱性极强的为砧木1103P;抗旱性强的为A17、A15;抗旱性一般的为B24、A48、B26、A34;抗旱性较弱的类型为A35、克瑞森。
One year old F1 hybrid progeny （A15, A17, A34, A35, A48） of ♀V. amurensis Zuoshanyi×♂SO4 and two clones （B24, B26） of ♀V. amurensis Zuoshanyi×♂101-1 were used as materials to test their drought stress tolerance. Strong drought stress tolerance of potted rootstock 1103P and V. vinifera Crimson Seedless were used as double controls. The materials were treated with moderate water stress, the soil relative water content （SRWC） was maintained at about 45%. SRWC of control was maintained at about 80%. With three replicates for each treatment the leaf relative water content, electrical conductivity, leaf thickness, chlorophyll content, MDA content, root activity, CAT and POD activity were tested after 25 days of drought stress treatment. Results indicated that the clones A17 and A15 had strong drought resistance, but they were still weaker than 1103P. The drought resistance level of B24, A48, B26 and A34 were medium, and they were all better than Crimson Seedless. A35 showed similar drought resistance with Crimson Seedless.
