Abstract

Empetrum nigrum var.japonicum has medicinal value,which grows slowly and has narrow distribution .It is a rare and endangered plant in China.With the Empetrum nigrum var.japonicum as the object of study,the new branches were divided into three types:extended branch,caespitose branch and axillary branch.Comparison of the proportion of new branch types,leaf traits and biomass in three habitats,provides useful information for cultivation and protection.The results showed that the extended branch and caespitose branch were the most common type of new branches,and SP=2,SP=3 was the most common type in the three habitats.There were fewer new branches in the forest edge and stone gap than in the sparse forest,the leaf area and the ratio of leaf length to width of the stone gap were the largest,the biomass of flower bud was the largest,the biomass of branch was smaller than that of the sparse forest,and the sexual reproduction ability was stronger.The ability of producing new branches is high and the ability of asexual reproduction is strong.There was no significant difference in the average length of new branches between different habitats and different types,but the diameter of elongated branches in sparse forests was significantly higher than that of forest edge and stone gaps,and there was also significant difference between extended branches and caespitose branches (P<0.05).

Key words： Empetrum nigrum var.japonicum; habitats; new branch type; leaf character; biomass
