为研究紫背冷水花（Pilea purpurella）对弱光胁迫的适应性,采用SPAD-502便携式叶绿素仪和Li-6400便携式光合测定仪对其在弱光胁迫下的叶绿素含量、叶绿素荧光参数等各项指标进行了测定。结果表明:紫背冷水花耐荫性较好,在20100μmol-2·s-1的弱光条件下仍然能够正常生长。在弱光胁迫下,相对叶绿素含量先降后升,且有一定的反复波动。10100μmol-2

　　To study the adaptability Pilea purpurella under weak light stress, the Chlorophyll content and chlorophyll fluorescence parameters were detected by SPAD-502 and Li-6400.The results showed that P.purpurella had good shade tolerance, and can grow normally under 20-100μ mol-2 · s-1 weak light condition.Under the weak light stress,the Chlorophyll content was decreased firstly than increased.The Fv/Fm value was not effected by 10-100μmol-2 ·s-1 weak light condition, but under 100μmol-2 · s-1 light condition, the photosynthetic energy tran...
