T. Yoneyama ; L. Handley ; C. Scrimgeour ; D. Fisher ; J. Raven | 1997This work explored whether the natural abundances of carbon and nitrogen isotopes could be used to describe the movement of C and N within wheat plants; we also considered whether isotopic analyses of aphids or their honeydew would substitute fo[...]article/chapitre/communication
B. Shelp ; E. Marentes ; A. Kitheka ; P. Vivekanandan | 1995Boron (B) is a micronutrient essential for the normal growth of monocots, dicots, conifers, ferns and several diatom species. Boron deficiency causes many anatomical, physiological and biochemical changes, making it difficult to identify a prima[...]article/chapitre/communication
J. Hibberd ; W. Jeschke | 2001Parasitic plants form intimate contacts with host tissue in order to gain access to host solutes.

W. Jeschke ; P. Baumel ; N. Rath ; F. Czygan ; P. Proksch | 1994A recently developed empirically based modelling technique was used to quantify uptake, flow and utilization of C and N in Lupinus albus L., uninfected and parasitized by Cuscuta reflexa Roxb. plants over a 12 d period during flowering and early[...]article/chapitre/communication
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
A. Peuke ; W. Hartung ; W. Jeschke | 1994Seedlings of Ricinus communis L. cultivated in quartz sand were supplied with a nutrient solution containing either 0.2 mol m(-3) NO3- or 4.0 mol m(-3) NO3- as the nitrogen source to obtain insufficiently (low supply, nitrogen-limited) or well-f[...]article/chapitre/communication
A. Peuke ; W. Jeschke ; W. Hartung | 1994Seedlings of Ricinus communis L. were cultivated in quartz sand and supplied with media which contained either different concentrations of nitrate or ammonium nitrogen and were treated with a low salt stress. The concentration of ABA was determi[...]thèse/mémoire
