[目的]研究不同光照处理对绿萝表型可塑性的影响。[方法]比较了叶面积、茎长、叶离心率和鲜重几项指标。[结果]不同的光照强度能显著影响绿萝叶片面积,且不同处理间差异显著;不同的光照强度能显著影响绿萝的茎长生长,且不同处理间差异极显著;不同的光照强度能显著影响绿萝叶片长、宽的生长,使叶离心率发生变化,改变其叶基的形状。[结论]为合理地开发绿萝资源,更好地发挥其生态意义和经济价值提供科学依据。
Effects of Different Illumination on Scindapsus aureus Phenotypic Plasticity
[Objective]The research aimed to study the effects of different light treatments on Scindapsus aureus phenotypic plasticity. [Method]Four indexes, including leaf area, grass height, leaf centrifugal rate and fresh weight, were compared in the research. [Result]The result showed that different illumination intensities greatly affected the leaf area of Scindapsus aureus, and the different treatments had notable differences. Different illumination intensities could also greatly affect the grass height, and different treatments had most notable differences. Different illumination could dramatically influence the length and width of the leaf, consequently led to the changes of leaf centrifugal rate and the shape of its foliar base. [Conclusion]The study can provide scientific basis for reasonably developing Scindapsus aureus resources, and better play its ecological meaning and economical value.
