Identification of F-1 hybrids Pinus nigra J.F. Arnold x P-sylvestris L., P-Nigra J. F. Arnold x P-densiflora Siebold et Zucc. and P-nigra J.F. Arnold x P-thunbergiana Franco by internal and external morphometric traits

摘要

Nineteen needle and shoot morphological and anatomical traits of three F-1 hybrids (Pinus nigra J. F. Arnold x P. sylvestris L., P. nigra J. F. Arnold x P. densiflora Siebold et Zucc. and P. nigra J. F. Arnold x P. thunbergiana Franco), and their parental species were analysed using discriminant analyses to distinguish parental species and hybrids.
