Projects & Species




Rare Arran Whitebeams — Hedlundia
Conservation Programme | Ongoing
In collaboration with the National Trust for Scotland, In Vitro Microplants Ltd is developing specialist propagation methods for three of Scotland's rare Arran whitebeams: Hedlundia Arranensis, H. Pseudofennica and H. Pseudomeinichii.
These threatened trees present significant challenges for conventional propagation, making tissue culture a valuable tool for conservation.
Our work includes:
Establishment of sterile cultures from carefully selected plant material.
Development and optimisation of species-specific multiplication protocols.
Investigation of oxidative browning, antioxidant treatments and culture survival.
Rooting and acclimatisation trials to support successful transfer from laboratory to nursery conditions.
Our conservation programme has successfully progressed all three Hedlundia species through in vitro establishment, multiplication, rooting and ex-vitro acclimatisation. This represents an important step towards producing young trees for future conservation and restoration programmes.
Project partner: National Trust for Scotland.




Wych Elm (Ulmus glabra)
Conservation & Commercial Propagation | Ongoing
In collaboration with the Royal Botanic Garden Edinburgh, In Vitro Microplants Ltd has developed and applied specialist micropropagation methods for selected Scottish wych elm (Ulmus glabra) clones.

Our work includes:
Establishment of sterile cultures from selected elm material.
Clonal multiplication of individual elm genotypes under controlled laboratory conditions.
Optimisation of culture media and plant growth regulators to improve shoot development.
Rooting and acclimatisation of microplants.
Transfer of young trees into nursery growing conditions.
Production and delivery of elm plants for conservation programmes.
Project achievements
We have successfully multiplied and acclimatised several selected wych elm clones, progressing plants from laboratory cultures to established young trees.
Our propagation methods are continually refined to improve plant quality, rooting performance and survival during transfer to ex-vitro conditions.
Project collaborator: Royal Botanic Garden Edinburgh.
