B. Deinum | 1976article/chapitre/communication
A 3 D model of tree architecture is developed to simulate the photosynthesis of peach trees. The model uses a simple graphical procedure to compute the light interception and the corresponding photosynthesis. It allows to consider complex canopy[...]article/chapitre/communication

M. Stitt ; D. Schulze | 1994Experiments are described in which tobacco (Nicotiana tabacum L.) transformed with antisense rbc S to decrease expression of ribulose-1,5-bisphosphate carboxylase-oxygenase (Rubisco) was used to evaluate the contribution of Rubisco to the contro[...]article/chapitre/communication
S. Pelleschi ; J. Rocher ; J. Prioul | 1997The time course of the modifications induced by a mild water stress has been examined for photosynthesis and several traits of carbohydrate metabolism in adult leaves of two inbred maize lines of North American and European origins, respectively[...]article/chapitre/communication

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

D. Wright ; D. Read ; J. Scholes | 1998A comparative analysis of daily carbon (C) budgets and aspects of the C physiology of clover (Trifolium repens L,) colonized by vesicular-arbuscular (VA) mycorrhizal fungi was carried out over a 70 d growth period under conditions designed to en[...]article/chapitre/communication
F. Gastal ; G. Lemaire | 2002The rate of N uptake of crops is highly variable during crop development and between years and sites. However, under ample soil N availability, crop N accumulation is highly related to crop growth rate an to biomass accumulation. Critical N conc[...]article/chapitre/communication
F. Haile ; L. Higley ; X. Ni ; S. Quisenberry | 1999Plant tolerance to injury from insect herbivores has several advantages as a pest management approach. However, its use is limited because mechanisms conferring plant tolerance are not well understood. We hypothesize that plant physiological res[...]article/chapitre/communication
J. Hibberd ; W. Quick ; M. Press ; J. Scholes | 1998The achlorophyllous holoparasitic angiosperm Orobanche cernua reduced biomass accumulation of its tobacco host, such that 73-d-old plants achieved 29% of the biomass of control plants. The difference in biomass between infected and uninfected to[...]
