Pflanzenbauliche Forschung zwischen gestern und morgen

Permanent grasslands consist of multiple species and cultivars, whose compositions change over time. Identifying such changes visually is laborious at species level and impossible at cultivar level. Two DNA-based methods were tested for this purpose.

Thanks to the selection of new clones, the ‘Räuschling’ grape variety has become more consistent in terms of cultivation and wine quality. Multi-year trials have shown that four new clones stabilise yield and quality and reduce the risk of both berry splitting and Botrytis (grey mould) infestation.

Plant-plant interactions can contribute to yield security and resilience. The significance of these interactions in agriculture is contentious, not least of all because the mechanisms are largely unclear. This study summarises the current state of knowledge.
