| 摘 要： | 应用LI-6400光合作用测定系统,研究了广州市四种园林常用藤本植物光合作用及影响因子分析。结果表明,龙吐珠Clerodendrum thomsoniae和金杯藤Solandra maxima的最大净光合速率较大,使君子Quisqualis indica的最小。龙吐珠的光补偿点和光饱和点都较高,使君子的光补偿点和光饱和点都较低。植物含水率越高,其最大净光合速率和光补偿点就越高,相对叶绿素值与光饱和点之间亦存在此规律。

Photosynthesis and Influence Factors of 4 Lianas Plants Species |

| Abstract: | The paper studies photosynthesis and influence factors of 4 main gardens lianas plants species (Clerodendrum thomsoniae, Lonicera japonica,Solandra maxima,Quisqualis indica) in Guangzhou by means of LICOR-6400 photosynthetic system. The results show that the maximum net photosynthetic rates ofClerodendrum thomsoniae andSolandra nitida are higher than others, and the maximum net photosynthetic rate ofQuisqualis indica is the lowest. The light saturation point and the light compensation point ofClerodendrum thomsoniae are higher. Meanwhile the light saturation point and the light compensation point ofQuisqualis indica are lower. As the water contents of 4 main gardens lianas plants species are higher, the maximum net photosynthetic rate and the light compensation point are higher. The similar law exists between the relative chlorophyll value and the light saturation point. |
