Other claims from this paper (7)
- Intervention effect In benign conditions diploid Spirodela polyrhiza grew faster than tetraploids.
- Intervention effect In benign conditions tetraploids had larger, thicker fronds than diploids.
- Association As salinity increased, the diploid growth advantage over tetraploids diminished.
- Association Ploidy per se explained a comparable amount of phenotypic variation in growth as the genotypic background.
- Association Ploidy per se explained substantially more variation in salt tolerance than the genotypic background.
- Observation There was evidence of rare within-genotype stochastic differences between tetraploids.
- Observation The phenotypic consequences of genome doubling in Spirodela polyrhiza are highly repeatable and largely deterministic.
