中文摘要: |
采用火棉胶印膜法,研究了不同程度干旱胁迫对不同抗旱类型大豆叶片气孔特性的影响。结果表明:经水分胁迫的大豆叶片气孔密度增加,气孔开口大小和单位叶面积气孔相对面积减小。但不同抗旱类型大豆品种间表现不同,气孔密度变化幅度大小顺序依次为:弱抗品种(A3)>中抗品种(A2)>抗旱品种(A1),调节气孔开张能力大小顺序依次为:抗旱品种(A1)>中抗品种(A2)>弱抗品种(A3)。 |
英文摘要: |
Stomatal characters of leaves on three different drought-resistant soybean cultivars under slight,moderate and heavy water stress were observed by the method of collodion imprinting film.The results showed that stomatal density of soybean leaves increased,stomatal apertura and relative stomatal area per leave area decreased under water stress.The sequence of stomatal density change range of different drought resistant cultivars was: the little drought-resistant cultivars A3>the middle drought-resistant cultivar A2>the strong drought-resistant cultivarA1.The ability to adjust stomatal open was: the strong droughtresistant cultivar A1>the middle drought-resistant cultivar A2>the little drought-resistant cultivar A3. |
