The rooting ability of in vitro shoot cultures established from a UK collection of the common ash (Fraxinus excelsior L.) and their ex vitro surviva

Key message

Shoot cultures from a population of British ash trees (Fraxinus excelsior L.) were assessed for their ability to form roots in vitro and to grow in nursery conditions. Most of the plants survived whether they had formed roots or not, but this was affected by a systemic contaminant. This information will be valuable for work aimed at overcoming ash die-back disease.
