By combining units we hope to bring expertise together for the benefit of managing forest health and productivity of Alberta’s forests in both the short and long term.

    As many other forest tree improvement programmes, the main elements in the teak improvement programme are: strategies, tree populations, operation and management, research and development. Strategies. Tree improvement strategies involve planning and execution for achieving general objectives, especially of long term breeding, propagation and. Knowledge of the seed biology of a tree species is essential to successful seed production and handling. The sexual life cycle must be known to plan for genetic improvement, production, collection, conditioning, storage, and planting of the seeds. B. Objectives 1.

Some trees can easily be grown from seed but, for some trees, it may be much quicker and easier to propagate them from cuttings. Seed propagation can be a tricky process for a number of tree species.

A small seedling can be very tiny and delicate when first germinated and often require much more care than a cutting. Growing Trees from Seed covers the ecology, abundance, fruit characteristics and edibility of the more than species discussed in this book.
