About 10000 soil samples, 519 thereof infected with potato cyst nematode (PCN), were studied during 1984-1988. Cysts from infected samples were tested by isoelectric focusing to identify PCN species. All the infected samples were also tested with H1-resistant (Satuma) and susceptible (Bintje) potato cultivars to separate resistance breaking populations. Cysts from the roots of Satuma were tested by two-dimensional electrophoresis. The potato seed production area in Finland was found to be free of PCN of any kind. In other parts of Finland all tested samples revealed G. rostochiensis banding pattern, but no G. pallida was found. Except for the most common pathotype Ro1-Ro4, we only found Ro2.

The two-dimensional braid heterogeneous-reinforced (BHR) polyvinylidene fluoride (PVDF) hollow fiber membranes which include PVDF polymer solutions (coating layer) and the two-dimensional braid as a reinforcement were prepared through the dry-wet spinning process. The influence of PVDF concentration in polymer solutions on performance of BHR hollow fiber membranes were investigated by terms of pure water flux, protein rejection, a mechanical strength test, and morphology observations by a scanning electron microscope (SEM). The results of this study indicated that the tensile strength of the BHR PVDF hollow fiber membranes was nearly 75 MPa and the hollow fiber membranes were endowed with better flexibility performance. The BHR PVDF hollow fiber membranes had a favorable interfacial bonding between the coating layer and the two-dimensional braid. The pure water flux decreased, while the rejection ratio increased with the increase of polymer concentration.
