摘要: 通过比较浙江大盘山不同海拔(A1:550~660 m,A2:700~800 m,A3:900~990 m,A4:1 000~1 015 m,A5:1 020~1 100 m)七子花(Heptacodium miconioides)叶片色素含量、含水量及比叶面积变化,探讨不同海拔对七子花生长的影响。结果表明,随着海拔的升高,叶绿素含量(包括叶绿素a、叶绿素b、叶绿素a+b)先增加后减少,在A3达最高值;叶绿素a/b比值、类胡萝卜素含量变化呈先低后高,在A3降至最低;比叶面积及叶片含水量,在较高海拔A4、A5都明显下降。七子花通过叶片色素、比叶面积、干重和含水量的变化以适应高海拔环境。

Abstract: By comparing the changes of pigment content, specific leaf area and water content of seven-son flower (Heptacodium miconioides) leaves at different altitudes (A1:550~660 m, A2:700~800 m, A3:900~990 m, A4:1 000~1 015 m, A5:1 020~1 100 m) in Dapanshan Mountain, the effects of different altitudes on seven-son flower were studied.The results showed that the contents of chlorophyll a, chlorophyll b and chlorophyll a+b of seven-son flower leaves increased firstly and then decreased and their peak appeared at A3, but the diversification trend of content chlorophyll a/b and carotenoid of seven-son flower leaves were reverse, decreased firstly and then increased and their bottom appeared at was in A3.Specific leaf area and water content of seven-son flower leaves decreased significantly at high altitudes (A4 and A5).Seven-son flower may be adapted to environmental factors at higher altitudes by the transformation of pigment content, specific leaf area and water content of leaves.

Key words: Heptacodium miconioides, altitude, pigment, water content, specific leaf area, Dapan Mountain, Zhejiang Province
