| 摘 要： | 叶片是植物进行光合作用的主要器官，比叶面积和气孔密度是植物叶片的重要的性状，它们在不同的海拔下存在着差异。通过对不同海拔珙桐比叶面积和气孔密度的测定，探讨其对海拔适应性，结果表明：比叶面积随着海拔的升高呈下降趋势，气孔密度随着海拔的升高呈先升后降趋势，在海拔1500～1700m珙桐表现出较好的适应性。 |
| 关 键 词： | 珙桐 海拔 气孔密度 比叶面积 |

| Abstract: | Leaves are plants' main organs of photosynthesis,specific leaf area and stomatal density are important traits in leaf,there are differences in different altitudes.Specific leaf area and stomatal density of Davidia involucrate at different altitudes are determined to explore its altitude adaptation.The result shows that: specific leaf area reveals a downtrend as the altitude becomes higher,but the stomatal density with elevation rising reveals uptrend first and then downtrend,at an altitude of 1500 m-1700 m ... |
| Keywords: | Davidia involucrate altitude stomatal density specific leaf area |
