- 摘要:
- 以三七为试材，采用人工控制环境试验，设置4个处理，昼温/夜温分别为10 ℃/0 ℃（T1）、13 ℃/3 ℃（T2）、16 ℃/6 ℃（T3）、19 ℃/9 ℃（T4），以28 ℃/18 ℃为对照处理（CK），持续时间设计1、3、5、7 d，系统测定不同处理对三七叶片光响应曲线和光合特性参数的影响，以期为三七低温灾害防御提供参考依据。结果表明：低温胁迫使三七叶片光合作用受到抑制，随低温胁迫加深，不同处理的最大光合速率和光补偿点与CK的差距逐渐增加；光合速率（Pn）、气孔导度（Gs）、蒸腾速率（Tr）、光补偿点（LCP）和光饱和点（LSP）随温度降低和持续时间延长呈下降趋势；T2、T3处理的胞间二氧化碳浓度（Ci）随持续时间的延长呈先上升后下降的趋势；Ls与Ci的变化趋势相反；T1处理的WUE先上升后下降，T2、T3、T4处理的WUE随持续时间的延长而上升。研究认为低温胁迫对三七叶片的光合作用有抑制的作用。
- Abstract:
- In order to study the effects of low temperature and treatment time on photosynthetic characteristics of Panax notoginseng leaves,four treatments were set up under controlled environment.Night temperatures and daytime temperatures were 10 ℃/0 ℃(T1),13 ℃/3 ℃(T2),16 ℃/6 ℃(T3) and 19 ℃/9 ℃(T4),and for control group(CK),night temperature and daytime temperature were set as 28 ℃/18 ℃.The plants in each treatment were treated for 1,3,5,7 days,respectively.The effects of different treatments and treatment time on Panax notoginseng were determined systematically in order to provide support for the prevention of low temperature disasters of Panax notoginseng.The results showed that the photosynthesis of Panax notoginseng leaves was inhibited by low temperature stress.When the temperature getting lower,the maximum photosynthetic rate and light compensation point declined significantly,while the photosynthetic rate (Pn),stomatal conductance (Gs),transpiration rate (Tr),light compensation point (LCP) and light saturation point (LSP) decreased with the decline of temperature and the extension of treatment time.Intercellular carbon dioxide concentration (Ci) increased at first and then decreased with the prolonging of treatment time in T2 and T3 treatments.However,Ls and Ci showed opposite trend during treatments.WUE increased at first and then decreased in T1 treatments,and increased with the extension of treatment time in T2,T3 and T4 treatments.It was concluded that low temperature stress could inhibit photosynthesis of Panax notoginseng.
