Den Nijs, C. Lock] The hatching differences ofGlobodera rostochiensis andG. pallida were assessed in potato root diffusate (PRD) of cv. Bintje, cv. Elkana and clone ZB35-29.G. pallida hatched better in the PRDs thanG. rostochiensis. It was shown that the experimental test conditions strongly influenced the hatching results. The water type used in the hatching tests had a significant discriminating effect on the species;G. rostochiensis reached hatch percentages of 60 to 90% in demineralized and tap water, whereasG. pallida never exceeded the 15%. These differences were independent of the various batches that were used or the different years the tests were carried out. Silver sand percolate had a inhibiting effect on the hatching of both nematode species. Boron and a high electrical conductivity may be responsible for this. The results are discussed from an ecological point of view as well as for research consequences.
