Epron, Daniel; Cabral, Osvaldo Machado Rodrigues; Laclau, Jean-Paul [UNESP]; Dannoura, Masako; Packer, Ana Paula; Plain, CarolineMade available in DSpace on 2022-04-28T19:03:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-08-11; Potassium (K) is an important limiting factor of tree growth, but little is known of the effects of K supply on the long-distance transport of photosynthetic carbon (C) in the phloem and of the interaction between K fertilization and drought. We pulse-labelled 2-year-old Eucalyptus grandis L. trees grow...
