Characterization of environmental stress responses during early development of Pringlea antiscorbutica in the field at Kerguelen.

•  Early development of Kerguelen cabbage (Pringlea antiscorbutica) was studied in the Kerguelen archipelago, its natural habitat, and under laboratory conditions. Polyamines, which are involved in developmental processes and responses to stress in several plant species, were used as markers of physiological status of P. antiscorbutica seedlings.
