Pseudoviviparous Reproduction of Poa alpina var. vivipara L. (Poaceae) during Long‐term Exposure to Elevated Atmospheric CO₂

Pseudovivipary at elevated pCO₂

Elevated atmospheric CO₂ may suppress photosynthetic capacity as extra carbon saturates metabolism and ties up mineral resources; this is particularly apparent when nutrients are scarce. Pierce et al. (613-622) demonstrate that the reproductive phase of pseudoviviparous alpine meadow grass (Poa alpina) is limited in the same manner as the vegetative phase, with reproductive phenology also being altered.
