W. Jeschke ; N. Rath ; P. Baumel ; F. Czygan ; P. Proksch | 1994Nodulated Lupinus albus L. was grown on quartz sand in the greenhouse and supplied with a N-free culture solution. Half the plants were infected with Cuscuta reflexa Roxb. at 33 DAS. An empirically based modelling technique was developed to quan[...]article/chapitre/communication
J. Hibberd ; W. Quick ; M. Press ; J. Scholes ; W. Jeschke | 1999Orobanche species are holoparasites which are very efficient sinks for host-derived solutes. Here, we report the use of direct measurements of xylem sap solute concentrations and water fluxes, together with a modelling procedure to calculate ele[...]article/chapitre/communication
P. Wilson ; S. Chakrabrty | 1998Computer software is now available for modelling the three-dimensional growth of plants. Visualisation of such models allows for representation and quantification of physical parameters which in the past have been too difficult to measure. Such [...]article/chapitre/communication

C. Fournier ; B. Andrieu | 2000The kinetics of elongation of individual internodes of maize stems were studied under field conditions. Thermal time courses of internode length were recorded using non-destructive methods, based on direct measurement of X-ray photographs or on [...]ouvrage

S. Carvalho ; E. Heuvelink ; R. Cascais ; O. Vankooten | 2002In many plant species, including chrysanthemum, a strong positive correlation between internode length and DIF [difference between day (DT) and night (NT) temperature] has been observed. However, Langton and Cockshull (1997, Scientia Horticultur[...]article/chapitre/communication
O. Turc ; J. Lecoeur | 1997Accurate prediction of the timing of leaf area development is essential to analyse and predict the responses of crops to the environment. In this paper, we analyse the two processes determining the chronology of leaf development-initiation of le[...]article/chapitre/communication
M. Plantegenest ; J. Pierre ; C. Caillaud ; J. Simon ; C. Dedryver ; S. Cluzeau | 1996The development of a detailed population dynamics model to simulate changes in grain aphid (Sitobion avenae F.) populations on wheat in field conditions requires the identification of every component of the system. The present study proposes a d[...]article/chapitre/communication
M. Jeuffroy ; C. Chabanet | 1994Seed number per pod in pea is variable. After fertilization, any number of ovules may abort in the pod. This paper describes an analysis of the relationship between pod growth and seed abortion rate. Pod dry weight was highly correlated to pod l[...]article/chapitre/communication
