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[...]

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[...]

J. Hibberd ; W. Jeschke | 2001Parasitic plants form intimate contacts with host tissue in order to gain access to host solutes. There are a variety of cell types within the host which parasitic plants could access to extract solutes. Depending on the degree to which the para[...]

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[...]

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[...]

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[...]
