Association of polyploidy with seed mass/germination in angiosperms: a review

Jerry M Baskin et al. Planta. .

Abstract

Polyploidization (diploidy → polyploidy) was more likely to be positively associated with seed mass than with seed germination. Polyploidy is common in flowering plants, and polyploidization can be associated with the various stages of a plant's life cycle. Our primary aim was to determine the association (positive, none or negative) of polyploidy with seed mass/germination via a literature review. We found that the number of cases of positive, none and negative correlates of polyploidization was 28, 36 and 21, respectively, for seed germination and 25, 5 and 3, respectively, for seed mass. In many plant species, ploidy level differs within and between populations, and it may be positively or negatively associated with germination (57.6% of 85 cases in our review). Ideally, then, to accurately assess intra- and interpopulation variation in seed germination, such studies should include ploidy level. This is the first in-depth review of the association of polyploidy with seed germination.

Keywords: Allopolyploidy; Autopolyploidy; Neopolyploidy; Seed germination; Seed mass.
