Abstract

Abstract

The efficiencies of plant branching and leaf unfolding are closely related to the environment.Pleioblastus amarus is a widely distributed dual-purpose bamboo species.The characteristics of branching and leaf unfolding and the strategy of resource allocation between branches and leaves under different environmental conditions were revealed,which can provide reference for scientific management of Pleioblastus amarus forest.A continuous and expansive bamboo (P.amarus)-fir (Cunninghamia lanceolata) mixed forest was studied,and four types of sample plots were set up in interfacial zones and central zones of both pure bamboo forest and mixed forest.The functional traits of branches and leaves of 1-2 y/o bamboo were investigated and determined,and the allometric relationships between the biomasses of branches and leaves were analyzed.The results showed that mixing promoted the growth of new bamboo crown,the increase of branch number and the expansion of growth space.The interfacial zones were beneficial to enhancing the growth capability of branches and leaves of new bamboo,with the increases of branch length,branch base diameter,the number of leaves,the leaf area and the biomass of branches and leaves.But the difference of functional traits of bamboo branches and leaves in the two interfacial zones was significantly reduced.In the interfacial zones of both pure bamboo forest and mixed forest,new bamboo had higher leaf-branch biomass ratio,leaf area ratio and leaf sprouting intensity,and the strategies of branching and leaf unfolding in pure bamboo forest and mixed forest were prioritized with "utilization" and "occupation",respectively.2 y/o bamboo significantly improved the resource allocation advantage of assimilation tissues,greatly improved leaf sprouting intensity and leaf unfolding efficiency,and generally adopted a "utilization" -oriented leaf unfolding strategy.There was a very significant allometric growth relationship between leaf biomass and leaf area or specific leaf area of 1-2 y/o bamboo,and there was a nearly isokinetic growth relationship between branch weight and leaf area.2 y/o bamboo increased the relative growth rate of leaf area-leaf mass and investment benefit.Clonal integration and mixed growth did not change the allometric growth relationship of branch-leaf size of 2 y/o bamboo,but had a significant effect on that of 1 y/o bamboo.In conclusion,there was apparently an age-dependent effect in branching and leaf unfolding of P.amarus in heterogeneous environment,and new bamboo was more sensitive.There was a significant resource trade-off relationship with clonal integration in the interface area of the experimental forest,which modified the growth plasticity of branches and leaves,and improved the competitiveness and adaptability of clonal ramets.
