The concept that photosynthetic flux is influenced by the accumulation of photo-assimilate persisted for 100 years before receiving any strong experimental support. Precise analysis of the mechanisms of photosynthetic responses to sink activity [...]article/chapitre/communication
J. Farrar | 1996It is argued that it is not possible to predict the flux of assimilate into a sink by making a measurement on that sink alone. Rather carbon flux is a whole-plant property and can only be predicted from measurements made simultaneously in source[...]article/chapitre/communication
J. Patrick ; C. Offler | 1996Photoassimilate transport from the sieve elements to the recipient sink cells, principally in the form of sucrose, provides a link between sink metabolism and compartmentation with phloem import. Phloem unloading has focused attention on photoas[...]article/chapitre/communication
A mathematical model of carbon accumulation by growing fruit is presented. The model implicitly incorporates the concepts of sink activity and sink size but avoids the need to stipulate sink strength. In addition to sink activity and size, carbo[...]article/chapitre/communication
K. Walsh ; M. Thorpe ; P. Minchin | 1998It is concluded that the permeability of the soybean nodule to gases is not linked to the supply of solutes or water via the phloem to the nodule. Nodule respiration and nitrogenase activity were less affected by diel variation and shading treat[...]article/chapitre/communication

R. Schaufele ; H. Schnyder | 2001The effect of defoliation on the deposition of carbon (C) and nitrogen (N) and the contribution of reserves and current assimilates to the use of C and N in expanding leaf tissue of severely defoliated perennial ryegrass (Lolium perenne L.) was [...]
