| Abstract: | Denote by  the set of trees of order 2k with perfect matchings. GUO Guo, Linear Algebra Appl. 368:379–385, 2003.] determined the largest value of Laplacian spectral
radii μ(T) of the trees T in  and gave the corresponding tree T in  whose μ(T) reaches this largest value. In this paper, we determine the second to the sixth largest values of μ(T) of the trees T in  and also give the corresponding trees T in  whose μ(T) reach these values. |
