Publications
NIBIOs employees contribute to several hundred scientific articles and research reports every year. You can browse or search in our collection which contains references and links to these publications as well as other research and dissemination activities. The collection is continously updated with new and historical material.

Furfurylation of wood samples can lead to different outcome (different chemistry) and product properties depending on parameters such as pH-value, catalyst, amount of water, time and temperature. Changes in the furfurylation process can even lead to a deterioration of product performance, such as lower durability in comparison to other furfurylated products. How is it possible to detect these changes in chemistry of a furfurylated wood product? To answer this question confocal laser scanning microscopy was used. The expectation was to detect different emissions of the auto fluorescent furfuryl alcohol if differences in chemistry exist. Additionally to the differences in emitted wavelength, the area in the wood structure of different emissions was under investigation. It was the aim to detect whether different product performance of a furfurylated product or different furfurylation processes could be related to changes in chemistry and this was expected to be visualized by CLSM.

Development of ontogenic resistance to powdery mildew (Podosphaera aphanis) on strawberry leaves has been reported, however, the components of resistance have not been elucidated. Five developmental stages of strawberry leaves were identified and assigned numerical values from newly emerged and unexpanded (S1) to fully expanded and dark green (S5) of cvs. Korona and Senga Sengana. The upper and lower surface of the leaves were inoculated from each of the five leaf developmental stages and incubated under controlled conditions. The effect of leaf age on germination, infection efficiency, latency period, and sporulation were later evaluated. All responses were significantly (p = 0.05) affected by leaf age. Germination percentage, infection efficiency, and sporulation were highest, and latent periods were shortest on S1 leaves of both cultivars. On Senga Sengana, germinating conidia produced fewer secondary hyphae during infection. Conidia produced very few secondary hyphae and did not sporulate on S3 leaves, and no infections established on S4 or S5 leaves. The high success of infection and colonization of P. aphanis on S1 leaves indicates that disease is established preferentially on emergent and expanding leaves and these should be the target of management strategies.
