Immediate vs. evolutionary consequences of polyploidy on clonal reproduction in an autopolyploid plant.

ABSTRACT: Background and Aims:Clonal reproduction in polyploids is expected to exceed that in diploids, due to either the immediate direct effects of whole-genome duplication (WGD) or selection during establishment. The timing of polyploidy effects on clonality are largely unknown despite its hypothesized influence on polyploid success. This study tests the direction and timing of divergence in clonal traits in diploid and polyploid Chamerion angustifolium. Methods:Root bud production and biomass allocation patterns were compared between diploids and synthesized tetraploids (neotetraploids), and between neotetraploids and naturally occurring tetraploids grown in a common environment. Key Results:Neotetraploids produced more root buds and fewer sexual structures than diploids and natural tetraploids;
