摘  要:
[目的]研究不同种源和不同修剪方式的牛大力叶片叶绿素荧光参数的影响。[方法]选择成熟的牛大力叶片通过暗适应后,采用MINI-PAM测定初始荧光(F0)、最大荧光(Fm)、PSII光量子效率(Yield)和光合电子传递速率(ETR)等叶绿素荧光参数。[结果]牛大力不同种源间的F0和Fm差异不显著,其中种源7猪仔笠的光合效率稍高于其他几个种源。所有种源在广东气候条件下均能正常生长。不同修剪方式与自然生长的牛大力叶片叶绿素荧光参数下降不明显,不降低光合作用。F0和Fm在各修剪方式中比较接近。[结论]控制高度1 m,保留主茎蔓1条和侧蔓4条的修剪方式与自然调控的牛大力叶片的光合能力相当。种源7猪仔笠的光合效率稍高于其他几个种源。

摘  要:
[Objective]The research aimed to study the influence of the different seed provenance and pruning on the Chlorophyll Fluorescence Parameters of Millettia speciosa.[Method] Select mature Millettia speciosa after dark adaptation,the chlorophyll fluorescence parameters such as original fluorescence( F0),maximum fluorescence( Fm),PSII light quantum yield( Yield) and photosynthetic electron transport rate( ETR)were measured by MINI-PAM.[Result]There were no significant difference between Millettia speciosa seed provenance in F0 and Fm. NO. 7 Zhuzaili slightly higher than other seed provenance in photosynthetic efficiency. All seed provenance grew normally in Guangdong. There were no significant difference between pruning way and the natural growth in the chlorophyll fluorescence parameters. F0 and Fm were similar in the pruning way.[Conclusion]Which control the height of 1 meter,1 keep main vines and lateral shoots four pruning way and the natural regulation has the simliar leaf photosynthetic capacity. NO. 7 Zhuzaili slightly higher than other seed provenance in photosynthetic efficiency.
