Biomass Allocation and Growth Analysis on the Ramets of Epimedium koreanum Nakai Populations in Different Cultivation Habitats
摘要
Abstract
[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(0.486 8 g),leaf biomass(1.081 4 g),fruit biomass(0.250 5 g),and total biomass(1.821 4 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.关键词
