Popis: Seven half-sib families of Platanus occidentalis L., either genetically improved selections (TFS-09, TFS-24, WV-10, WV-14) or non-improved selections (Brazos-C, Brazos-D, Putnam), were grown outdoors in 2.3-L to 9.1-L containers, then transplanted in fall, spring, or summer to assess root regeneration potential (RRP) and initial (2 year) post-transplant landscape growth. TFS-09, TFS-24, Brazos-C, and Brazos-D were Texas selections, while WV-10, WV-14, and Putnam were from Tennessee and Kentucky. Generally, local half-sib families grew more rapidly than geographically distant families and some genetically improved selections grew more rapidly than non-improved selections, both in the landscape and nursery. Rapid growth of new roots and transplanted root dry matter were more consistently associated with successful transplant establishment across families than other measures of RRP. Survival was reduced after summer vs. spring or fall transplant.
