BioEnv-seminarium: “Inter- and intraspecies variation in seed longevity – implications for ex situ conservation”

Fiona Hay från Århus universitet pratar om fröer och vad som påverkar deras livskraft i ett längre perspektiv, vilket är av betydelse tex när man vill bevara dem i fröbanker, se mer nedan.

Kort sammanfattning och presentation

Many plant species produce seeds described as having orthodox seed storage behaviour: the seeds survive drying to low moisture content and subsequent storage at sub-zero temperatures. Further, their longevity – how long the seeds can stay alive for – is extended by reducing moisture content and temperature. We take advantage of this ability when we store seeds in conservation seed banks or seed genebanks. However, seeds of different species differ in their longevity. There is also variation in longevity between different seed lots within a species – which we can manipulate to some extent. Our research seeks to better understand inter- and intra-species variation in seed longevity for improved conservation outcomes.
