Abstract
Based on analysis of types and dynamics of buds,morphology and space structure of branches,the ecological adaptation and behavior of Dalbergia millettii liana in the subtropical evergreen broad-leaved forest of eastern China were studied.The results are as follows:(1)Both spring bud and summer bud may form the climbing or short branch,but there are great differences in the activity duration of bud and the branch length formed.Regeneration of old liana trunk will be mainly completed by adaptive growth of adventitious buds on it.(2)Node number and internode leggth of climbing branch are 7 and 6.5 times more than those of short branch,respectively.And they are easily influenced by light.Branching ratio of climbing brance at the edge of forest is 5 times greater than that in the inner forest.(3)Age structure of the liana population grows older with the succession of community,and D.millettii still belongs to an early liana of community.(4)D.millettii has some selective requirement to its hosts,among which Pinus massaniana is most often climbed by the liana.(5)The climbing capacity of D.millettii is strong.Individual liana may climb 2~15 tree plants and its horizontal expansion area varies from 24m2 to 260m2.关键词
