| Abstract: |
| 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. |
