Clonal Propagation of Mature Trees: Problems and Possible Solutionsonly from tissues of juvenile specimens, i.e., embryos or young seedlings. However, cloning of mature trees is generally preferred over cloning of embryos or seedlings because often it is not possible to determine if these embryos or seedlings have the genetic potential to develop the desired qualit
