Life cycle stage, flooding depth and adventitious root formation
This study finds that adventitious root formation is constrained in juvenile compared to mature plants, and is delayed by deep compared to shallow flooding.

Genome size, ploidy level and reproductive mode of Sorbus
The authors find that the coexistence of apomictic tetraploids and sexual diploids drives the production of novel polyploid cytotypes in S. austriaca.
