不同地被竹光响应曲线拟合及光合特性
|
摘要
为研究不同地被竹的光合特性和环境适应性,利用直角双曲线模型、非直角双曲线模型、指数函数模型和直角双曲线修正模型对3个不同地被竹种光响应曲线进行拟合,并对拟合光合参数进行分析,还对不同地被竹的叶绿素和水分利用效率进行了比较分析。结果表明,不同模型均具有较高的R2值,但大部分光合参数在不同模型间差异显著(P <0.05),直角双曲线修正模型拟合得到的参数与观测值最为吻合;Amax在不同地被竹种中无明显差异,但α和Rd值在铺地竹、菲黄竹、黄条金刚竹间依次下降,而Is和Ic的变化趋势则相反;具有较强耐荫特征的铺地竹叶片中的总叶绿素和叶绿素b最高,而在黄条金刚竹中最低。铺地竹还具有较高的水分利用效率,显著高于(P <0.05)黄条金刚竹和菲黄竹。以上结果可以为地被竹的引种栽培和园林应用提供科学依据。
To study the photosynthetic characteristics and environmental adaptability of different dwarf bamboo resources, the models of rectangular hyperbola, non-rectangular hyperbola, exponential function, and modified rectangular hyperbola were used to simulate the photosynthesis-light response curve of three different ornamental dwarf bamboos. After that, the photosynthetic parameters, chlorophyll and water use efficiency were analyzed. Results indicated that relative high R2 values could be achieved using different models, while most photosynthetic parameters possessed significant difference(P<0.05) among the different models, and the modified rectangular hyperbola model was most consistent with the measured value. Of the Amax evaluated, significant difference was not detected among the different dwarf bamboos, while the values of α and Rd were significantly reduced along with the bamboo species of Sasa argenteistriatus, Sasa auricoma, and Pleioblastus kongosanensis. However, the values of Is and Ic showed complete reverse variation patterns. It was also found that S. argenteistriatus, one of the relative high shade-tolerant dwarf bamboo, had the highest total chlorophyll content and the highest chlorophyll b, while these parameters were lowest in P. kongosanensis. Furthermore, S.argenteistriatus had the highest water use efficiency, and significantly higher than P. kongosanensis and S. auricoma. Overall, our results can provide some basis for the introduction, cultivation and landscape application of dwarf bamboo resources.
