Higher seed size and germination rate may favour autotetraploids of Vicia cracca L. (Fabaceae)

Popis výsledku v původním jazyce

The phenotypic effect of increased cell size in polyploid angiosperms has been repeatedly described; the ecological consequences of the gigas effect are, however, relatively poorly understood. Here, we investigated the effect of cytotype, seed weight, and inter-population variation on seedling germination and growth in diploid and autotetraploid Vicia cracca L. in a common garden experiment. Seeds used in this study originated in the contact zone of the cytotypes in Central Europe. Tetraploids had heavier seeds than diploids and greater germination rates irrespective of seed size. Both seed weight and germination rate displayed high inter-population variation. Further, tetraploids seem to germinate earlier and deposit fewer reserves into the seed bankthan diploids. Mean above-ground biomass and seedling height were similar in the two cytotypes of V. cracca. Nonetheless, the tallest tetraploid seedlings were taller than the tallest diploid seedlings, which may be advantageous under str
