This work was carried out as part of Sandy Hetherington's internship at the Oxford University Botanic Gardens and Arboretum. This was a three month internship as part of his DPhil with the Oxford Interdisciplinary Bioscience Doctoral Training Partnership. The work was funded by the BBSRC.
The work could not have been carried out without the kind help of Alison Foster, Ben Jones and Denis Filer.
