| 利用开顶箱（Open Top Chambers, OTC）模拟增温的方法，研究了短期变暖对鹅绒委陵
菜健康的影响。结果表明，短期变暖后降低了鹅绒委陵菜的萌蘖株死亡、增加了单位长度匍匐茎
的萌蘖株数目和其死亡率，同时叶片数目、高度和健康率比对照增加，匍匐茎长度和匍匐茎上萌
蘖株数目比对照减少，同时所有表征指标中只有萌蘖死亡率和叶片高度比对照有显著变化

| Abstract: |
| The research was carried out to investigate health of the response of Potentilla anserina L.
individual to simulated warming by the method of open top chamber (OTC). The mortality rate of ramet
and height of leaf were signifi cantly reduced (p ＜ 0.05), due to simulated warming. The number of
ramet and its mortality rate of per length of creeping stem showed increased trend. Height, health rate
and amount of leaf were improved by OTC. The length of creeping stem and number of ramet were
lower than that of control as well. |
