同产地不同种源北五味子光合作用比较研究

Comparative study on photosynthesis of schisandra chinensis from different provenances in same habitat

采用美国CI-340便携式光合作用系统,对同一产地吉林种源、黑龙江种源、凤城种源、本溪种源五味子的净光合速率(Pn)、气孔导度(C)、胞间CO_2浓度(Ci)等进行了比较测定,从调查相关指标的平均值、日变化情况、经方差分析进行讨论,供同行参考。

CI-340 portable photosynthesis system was used,and the net of light on the same origin of Jilin provenance,Heilongjiang provenance,Fengcheng provenance,Benxi provenance of Schisandra chinensis photosynthetic rate( Pn),stomatal conductance( C),intercellular CO_2 concentration( Ci) were measured. The average value of index,diurnal variation and analysis of variance are discussed for reference.
