摘要:

通过对比不同产地滇重楼与相同产地不同来源滇重楼的光合作用能力,研究其生理适应性,以期为滇重楼引种种植及资源保护提供理论基础。利用LI-6800光合作用仪,检测分析不同产地相同品种与相同产地不同来源滇重楼的光合生理的变化模式。结果表明,采自滇西产地滇重楼的光合能力均高于滇东南产地,但差异较大;滇东南产地滇重楼的光合速率差异不大,但其数值低于滇西产地。而不同产地的滇重楼移栽到相同环境下,其叶片气孔导度(Gs)、蒸腾速率(Tr)以及水分利用效率(WUE)值均低于当地品种,而胞间CO2浓度与环境CO2浓度的比值(Ci/Ca)则高于当地品种,移栽后的品种光合能力低于当地品种。研究认为,滇西地区所产滇重楼比滇东南地区光合作用能力更强,以大理州永平县滇重楼尤为突出,而移栽后的品种光合能力以及水分利用率低于当地品种。因此在滇重楼的栽培中,应筛选栽培地产的品种进行人工扩大化种植。

Abstract:

To study the adaptability of Pairs polyphylla var. yunnanensis and provide a theoretical basis for its introduction, planting and resource protection, we investigated the photosynthetic capacity of P. polyphylla var. yunnanensis from different growth areas and different sources from the same area. LI-6800 photosynthesis instrument was used to detect the photosynthetic capacity of the same variety from different areas and different sources from the same area. The results show that the photosynthetic capacity of P. polyphylla var. yunnanensis collected from western Yunnan is higher than that from southeastern Yunnan, and the difference is great. There is no significant difference in photosynthetic rate of P. polyphylla var. yunnanensis among different sources in southeastern Yunnan, but the value is lower than that in western Yunnan. However, the leaf stomatal conductance (Gs), transpiration rate (Tr) and water use efficiency (WUE) of P. polyphylla var. yunnanensis from different habitats are lower than those of local varieties, while the ratio of intercellular CO2 concentration to environmental CO2 concentration (Ci/Ca) was higher than that of local varieties, and the photosynthetic capacity of transplanted varieties is lower than that of local varieties. The study shows that the photosynthetic capacity of P. polyphylla var. yunnanensis in western Yunnan is stronger than that in southeastern Yunnan, especially in Yongping County of Dali prefecture. However, the photosynthetic capacity and water use efficiency of the transplanted varieties are lower than those of the local varieties. So in the cultivation of Pairs polyphylla var. yunnanensis, the cultivated local varieties should be selected for artificial expansion.

Key words: Pairs polyphylla var. yunnanensis, geographical origin, resource protection, provenance, photosynthesis, light response curve
