Micropropagation of Mature Trees of Ulmus Glabra, Ulmus Minor and Ulmus Laevis

2007
, 1999), has devastated the elm populations of Europe, North America and central Asia. This has lead, in both Europe and North America, to the beginning of breeding programmes in an attempt to produce resistant individuals. However, production of disease resistant elm trees via conventional breeding has met with limited success owing to the long time ...
