Temporal and spatial genetic comparisons were made in an appalachian stand of Liriodendron tulipifera L. (tulip tree). The population was stratified into five age clsses, and allele frequencies were tested by homogeneity chi-square test within and among plots. The homogeneity in allee frequencies were also evaluated for plot and subplot differences, et different age levels. Results revealed that the population of tulip tree is structured in time and space: however, neither one was recognized as a result of the natural selection process. The lack of consistent patterns for differences in allele frequencies for age classes does not support evidence of selection. One possible constraint ay be the presence of rare alleles. Another explanation may be the presencebetween genetic and statistical sampling at different life cycle stages. The susbstructure in space in much stronger than in time significant differences in allele frequencies at different coli for plts within age classes suggest that the population in substructure at the subplot level. The substructure is more likely to be associated with the epecies'reproductive biological characteristics such as mixed mating systems, and/or limited gene flow. |
