摘要：在这个城市建设不断发展的时代，越来越多的人们开始关注身边的生态环境。人们对于绿色景观的需求越来越高，希望身边的环境四季如春。因此为了满足人们的高审美需求，四季常绿、兼具观叶观果特性的冬青属植物从众多植物中被挖掘出来。它的突出的观赏性价值，渐渐为人们所熟知和喜爱。29283
但冬青属植物有许多树种存在生长慢、成苗周期长的特点。考虑到光是影响植物的生长与发育的主要因素，研究冬青属植物的光合作用有重要的理论意义和实际价值。本研究以长叶冬青、小叶冬青、杂交冬青三种引种冬青为研究材料，并以枸骨（本土冬青）作为比较材料，观察其形态指标上的差异，并对其相同光照条件下不同植物相对叶绿素含量及光合速率进行分析，最终从植物生长适应性的方面得出本土冬青最好，小叶冬青次之，长叶冬青最差的结论。该研究为日后继续推广冬青植物资源提供了参考依据。

The comparison of the ability to photosynthesis for Introduction of several species in ILEX in the Shanghai
abstract：
With the constant development of the city construction，more and more people start to pay attention to the ecological environment around themselves. People have higher and higher demand for the green landscape, they hope that environment around themselves is Four spring-like. Thus, In order to satisfy people's  high aesthetic demand, we found  ILEX  from kinds of plants, which is evergreen and have  ornamental characteristics of leaves and fruits. People gradually know and love the value of its outstanding ornamental characteristics.
But lots of species in ILEX have features of growing slowly and the long cycle of germination. Considering that light is the main factor to affect the growth and development of plants，it has important theoretical significance and practical value on researching the photosynthesis of ILEX. This research is used Ilex maclurei Merr.、Ilex ficoidea Hemsl. var . parvifilia S. H . Fu var . nov . ined. and ILEX cultivars as the material and use Ilex cornuta Lindl. et Paxt. as comparative material to observe its differences on morphological index, and then analyze different plant relative chlorophyll content and photosynthetic rate in the same light conditions. Finally, from the aspects of plant growth adaptability, the study has been concluded that Ilex cornuta Lindl. et Paxt is the best,
Ilex ficoidea Hemsl. var . parvifilia S. H . Fu var . nov . ined. is the next and Ilex maclurei Merr.is the worst. The study provides reference for the future continue to promote the Holly plant resources.
