摘要
研究了"大理茶"、"狮子头"、"松子鳞"3个云南山茶园艺品种的光合特性和相关的叶片特性。结果表明:3个山茶品种的光合作用主要受电子传递、羧化作用以及光能利用潜力的影响,且在高光强下均表现出光抑制。其中"大理茶"具有较高的光合能力;"狮子头"具有较高的光饱和点(LSP)和较低的光补偿点(LCP),表明其对光照强度具有较宽泛的适应性;"松子鳞"更适应低光环境,栽培时需注意遮荫。
The photosynthetic characteristics and related leaf traits of three horticultural cultivars of C.reticulata were investigated in this paper,taking C.reticulata ＇Dalicha＇,C.reticulata ＇Shizitou＇,C.reticulata ＇Songzilin＇ as material.The results showed that the main factors which affect the photosynthesis of these plant were electronic transfer ability,carboxylation and actual photochemical efficiency,and all the cultivars showed a slight photoinhibition at high light intensity.C.reticulata ＇Dalicha＇ demonstrated the highest maximum net photosynthetic rate.The light saturation point of C.reticulata ＇Shizitou＇ was the highest among the three cultivars,while its light compensation point was relatively low,which indicated a wide ecological range of adaptability to irradiance.C.reticulate ＇Songzilin＇ might need appropriate shade when planting,for its better adaptability to low irradiance.
