摘要	The Randic index of an organic molecule whose molecular graph is G is the sum of the weights (d(u)d(v))(-1/2) of all edges uv of G, where d(u) and d(v) are the degrees of the vertices u and v in G. We give a sharp lower bound on the Randic index of conjugated trees (trees with a perfect matching) in terms of the number of vertices. A sharp lower bound on the Randic index of trees with a given size of matching is also given.
