AGRE-0067 Upgrading the Genetic Quality of Hardwoods by Selection of Elite Germplasm and Conservation on Marginal and Abandoned Farmland 1 March 1991 - 29 Febuary 1992

Afforestation of marginal and abandoned farm land with broad leaf trees requires suitable planting material. This project assessed the feasibility and economics of this from a wide range of European trees including Acer, Alnus, Betula, Camellia, Fagus, Fraxinus, Juglans, Prunus, Quercus, Syringa, Tilia, Ulmus. Sterile cultures have been successfully initiated for all species using material of different physiological ages from immature embryos, embryonic axes, seeds, buds excised from seedlings, adolescent trees, adult trees, adult scions on grafted plants, forced dormant twigs and root suckers. It has been established that such techniques increase the facility of initiating cultures and increase the rate of shoot production. Micropropagation rate in vitro is strongly affected by genotype for Quercus, Castanea, Tilia and Syringa whereas for other species such as Betula and Prunus the propagation rate can be experimentally increased by choosing appropriate media.
