| 摘 要： | 通过设计7个钙磷浓度室内水培模拟试验，进行不同钙磷胁迫杉木叶绿素及其荧光参数的比较，探讨钙对低磷环境杉木抗逆性的影响。结果表明：随着低磷胁迫时间的推移，不同钙浓度处理杉木叶绿素含量变化明显，与正常供养CK处理相比，钙对缓解低磷逆境杉木叶绿体受伤程度、保持较高光合效率有显著作用，其中钙浓度Ⅳ（2.0 mmol/L）和Ⅴ（1.0 mmol/L）的这种作用尤为明显。无磷无钙Ⅵ处理条件下杉木叶片PSⅡ反应中心破坏最为严重，且受光抑制程度最大，处理Ⅲ和Ⅳ则较小。施钙可有效缓解低磷胁迫对Fm值的抑制作用。

| Abstract: | To explore the effect of calcium on increasing the productivity of Chinese fir plantations in the Southern forest region with low phosphorus,the hydroponic cultures with seven different Ca levels treatments were designed.A study was carried out on the different law of chlorophyll contents and chlorophyll fluorescence characteristics among different treatments during low phosphorus stress.The differences in chlorophyll contents of Chinese fir among different Ca levels treatments became significant gradually,... |
