The Transport of Carbohydrates in Australian Bracken

Abstract

Radioaotive carbon dioxide was fed to braoken fronds and the form in whioh the labelled produots of photosynthesis were moved into the rhizome and to growing buds determined as suorose. It was shown that the products moving away from one frond were severely limited in their spread in the vascular system of the rhizome, being confined to part of the phloem of two of the thirty or so bundles in the neighbourhood of the frond, but spreading into more of the bundles in more distant parts of the rhizome.
