The effects of freeze-thaw cycles and leaching on the loss of soluble carbohydrates from leaf material of two subantarctic plants
Leaves and litter of two phanerogams (Acaena magellanica (Lam.) Vahl and Poa flabellata (Lam.) Hook. f.) were collected in spring on the subantarctic island of South Georgia. Leaves immersed in water lost up to 80% of their total available soluble carbohydrates after 6–8 h. The loss of K+ and PO 4 3...
