The wooded area Nursery handbook - a joint attempt among the dep. of wooded area technological know-how, Oregon nation college, and the U.S.D.A. wooded area provider, department of country and personal Forestry - offers state-of-the paintings information regarding present bareroot-nursery practices and study. The handbook emphasizes all phases of seeding creation from nursery-site choice throught outplanting. Twenty-one bareroot nurseries and 8 seed-processing vegetation have been surveyed with in-depth questionnaires and the survey effects interpreted and included into chapters written by way of prime scientists and practising nursery managers. Over 250 humans previewed the handbook on the Bareroot Nursery know-how Workshop, held at Oregon nation collage in October 1982. The becoming measurement and class of the bareroot-nursery underscores the urgent want for an up to date synthesis corresponding to this

Although not easily adaptable to Northwest terrains for natural-stand collection, mechanized cone collection should play an important future role when western seed orchards are in full production. 7 Cone storage Cones are stored (1) because processing equipment is not usually capable of extracting seeds from all harvested cones at once [81]; (2) to decrease cone moisture content, thereby reducing kiln drying time; and (3) to artificially ripen seeds of species such as true firs and improve seed-germination potential.

Douglas-fir [125], several species of pines [13, 76], and white spruce [150, 152] have also shown increased germination during artificial ripening. However, de spite the findings of various researchers and the potential benefits, artificial ripening has not been extensively used for conifers other than true firs in the Northwest —probably because there is more risk of poorer germination and reduced seed yield in other species. 4 Weather Weather conditions significantly impact cone collection. ) for which year-round collection is possible, the optimum cone-collection period for most conifers at any given location is relatively short.
