Cold Hardiness in Intra-Specific Hybrids of Tulip Poplar

The study herein reported presents preliminary data from a continuing investigation of intra-specific hybridization in tulip poplar ( Liriodendron tulipifera L.). A fundamental question in the study is the inheritance of cold-hardiness, particularly in crosses involving northern and southern populations. The natural range of tulip poplar extends from central New York (Lat. 43 N), south to southern Louisiana and Mississippi, and into northern Florida (Lat. 30 ° N); thus providing experimental material with a large north-south differentiation.
