- 摘要:
- 为了促进五叶地锦变色期的栽培生产及种植养护，进而阐明其生长发育的最适光环境，以五叶地锦变色期4个阶段（CⅠ、CⅡ、CⅢ、CⅣ）的叶色参数（Lab模型）、色素含量以及光合生理参数相关指标，进行单因素方差分析及相关性分析。结果表明，在变色期过程中，叶色参数a*值由-2.95提高到9.75，且差异显著；叶绿素含量下降的同时花色素苷含量上升，叶绿素含量和花色素苷含量在CⅣ阶段分别是CⅠ阶段的3.19%和26.19倍。叶色参数a*值与叶绿素含量呈极显著负相关，与花色素苷呈极显著正相关；五叶地锦在变色期最大净光合速率（Pnmax）、气孔导度（Gs）、水分利用率(WUE)、蒸腾速率（Tr）的光响应曲线的数值随着叶片变红持续下降，且均与叶绿素含量呈极显著正相关。光饱和点在CⅣ阶段显著降低为92.4 μmol·m－2s－1；光补偿点（LCP）在CⅡ阶段下降达到显著，仅为CⅠ阶段的20.14%；表观量子效率（AQY）在CⅢ和CⅣ阶段均显著下降，分别为CⅠ的62.50%和8.33%。暗呼吸速率(Rd)变化不显著。五叶地锦叶绿素下降而花色素苷上升造成叶色转红。叶绿素含量的降低造成五叶地锦光合能力下降，叶片在彻底变红前吸收强光的能力没有显著差异，但利用弱光的效率和对水分的利用能力降低。
- Abstract:
- In order to investigate the changes of photosynthetic characteristics during the discoloration period of the P. quinquefolia, and elucidate the optimal light environment for its growth and development. The leaves of P. quinquefolia were taken as the material to determine the four stages of the discoloration period ［CⅠ (dark green leaf)-CⅡ (red green leaf)-CⅢ (dark red leaf)-CⅣ(bright red leaf)］ leaf color parameters (Lab model), pigment content and photosynthetic characteristics are related index. Then carry out ANOVA analysis of variance and correlation analysis. The results showed that the leaf color parameter a* value was significantly increased from -2.95 to 9.75 during the discoloration period. The chlorophyll content decreased while the anthocyanin content increased, and the chlorophyll content and anthocyanin content were 3.19% and 26.19 times that of the CIV. stage, respectively.The leaf color parameter a* value was extremely significantly negatively correlated with chlorophyll content, and extremely significantly positively correlated with anthocyanin.The maximum net photosynthetic rate (Pnmax), stomatal conductance (Gs), water use efficiency (WUE), and transpiration rate (Tr) of P. quinquefolia during the discoloration period changes with the leaves red continued to decline, and both were significantly positively correlated with chlorophyll content. The light saturation point was significantly reduced to 92.4 μmol·m－2s－1in the CIV stage.And the light compensation point decreases significantly in the CⅡ stage, which was only 20.14% of the CⅠ stage; The apparent quantum efficiency decreased significantly to 62.50% and 8.33% of CⅠ compare with the CⅢ and CⅣ stages, respectively. The dark breathing rate does not change significantly. Research shows that the chlorophyll decreases and the anthocyanin increases are the main reasons that cause the leaf color to turn red. The decrease in chlorophyll content caused the decline of photosynthetic capacity of P. quinquefolia. There was no significant difference in the ability of leaves to absorb bright light before turning completely red, but the efficiency of using low light and the ability to use water were reduced.
