Studies on Embryogenesis of Woody Plants in Chinas of woody plants are described. The embryogenesis should go through two stages, that is, the young and the mature embryo stage, before they can be transferred to plantlet forming medium. Some factors affecting the induction freguency of embryogenesis, such as light and dark, temperature, medium and

A Model System for Gene Transfer in Conifers: European Larch and ,trant to these techniques, primarily because systems have not yet been developed for recovering whole transformed plants. There are four main components of an effective .-mediated gene transfer system. First, desirable genes and their promoters must be incorporated within the borders of the plasmid

Transformation of Hybrids ,brids are well suited to large scale planting in hydromorphic forest soils. However, these hybrids are highly susceptible to ., a pathogenic soil bacterium. The ability to induce galls and to regenerate plants from cells suggest that poplars may be an useful model for genetic engineering.

Somatic Cell Genetic Research in Forestry: Integration of Cytogenetics, Tissue Culture, and Moleculahuman and mammalian genomes. In forestry, somatic cell genetic protocols can eliminate constraints that have inhibited basic research on genetic constitutions of trees. Mammalian research areas with pertinence to forest tree genetics are somatic cell hybridization, chromosome — and microcell-mediate

Determination of Plantlet Regeneration Capacity of Selected Aspen Clones ,on marginal sites. Aspen wood has been employed in matchstick, paper-and plywood industries and has potential value for biomass and energy production. Vegetative propagation of aspen is extremely difficult by woody cuttings and uneconomical by root suckers and grafting. Consequently, large scale clo
