摘　　要：[目的]为探究朝鲜淫羊藿在种群构件水平上的生长特性,揭示生境对种群构件生物量结构特征、分配特征、生长规律的影响。[方法]选择平欧榛林、杨树林和松树林3个不同栽培生境,测定和分析朝鲜淫羊藿果实成熟期各构件的生物量特征、生物量分配、构件生长规律。[结果]平欧榛林生境朝鲜淫羊藿茎生物量(0.4868 g)、叶生物量为(1.0814 g)、果生物量(0.2505 g)、分株总生物量(1.8214 g)均显著高于杨树林、松树林生境。茎生物量分配以杨树林生境最高为32.64%,松树林次之,二者显著高于平欧榛林;叶生物量分配平欧榛林最高(59.41%),但3种生境差异不显著;果生物量分配平欧榛林(13.77%)最高、杨树林次之,松树林分配最小为9.18%。松树林生境朝鲜淫羊藿种群数量特征表型可塑性大,平欧榛林各构件生物量分配相对稳定,生境对叶、果、分株总生物量及叶生物量分配影响大。不同生境朝鲜淫羊藿各构件生物量及分配存在差异,且普遍存在显著的正相关关系。3种栽培生境下朝鲜淫羊藿种群各构件生物量与分株株高、分株总生物量间普遍存在线性同速生长规律,仅平欧榛林下茎生物量与株高、叶生物量与分株总生物量间呈幂函数异速生长关系。[结论]朝鲜淫羊藿分株在生长与物质分配上具有较大的生态可塑性和可调节性。[Objective]In order to investigate the growth characteristics and the influence of habitat on the biomass structure,allocation characteristics,and growth patterns of population components of Epimedium koreanum.[Methods]This study selected three cultivation habitats(hazelnut forest,poplar forest and pine forest)and the biomass characteristics,biomass allocation,and growth patterns of each component of E.koreanum fruit during its maturity period were measured and analyzed.[Results]The results showed that the stem biomass(0.4868 g),leaf biomass(1.0814 g),fruit biomass(0.2505 g),and total biomass(1.8214 g)of E.koreanum in the hazelnut forest habitat were significantly higher than those in the poplar and pine habitats.The distribution of stem biomass was highest in the poplar forest habitat at 32.64%,followed by the pine forest,both of which were significantly higher than those in the hazelnut forest;The distribution of leaf biomass in the hazelnut forest was the highest(59.41%),but there was no significant difference among the three habitats;The allocation of fruit biomass was highest in the hazelnut forest(13.77%),followed by the poplar forest,and lowest in the pine forest(9.18%).The phenotypic plasticity in population quantity characteristics of E.koreanum in the pine forest habitat were higher,and the biomass distribution of each module in the hazelnut forest was relatively stable.Habitats had a great influence on the total biomass and leaf biomass allocation of leaves,fruits and ramets.There was a significant positive correlation between the biomass of each module and the total biomass of ramets.There was a relatively consistent linear isokinetic growth pattern in ramet height,ramet biomass and relative growth.Only the relationship between stem biomass and ramet height,leaf biomass and total ramet biomass in Hazelnut forest showed a power function allometric growth relationship.[Conclusion]The ramets of E.koreanum had great ecological plasticity and adjustability in growth and material distribution.
