| Résumé : |
High altitude restoration with woody plants poses unique propagation challenges for natural resource managers including unpredictable wildland seed crops, short growing seasons, limited access to wildland plants, genetic considerations, seasonal staffing, uncertain and changing construction schedules, and short revegetation intervals. Although sexual propagation (seed) is generally less labor and equipment intensive, limited seed and long or unknown dormancy requirements can result in lengthy production schedules. Asexual propagation (cuttings) of woody trees and shrubs provides a viable alternative for high altitude settings. Dormant hardwood cuttings provide ease of handling and storage, however, access to donor plants, winter browsing, seasonal staffing, and reduced winter greenhouse operations often limit their use. Summer cuttings facilitate access to donor plants, reduced browse competition, improved percentage rooting, shorter production intervals, adequate labor, and efficient greenhouse operation. The selection of a propagation technique depends on genetic considerations, the propagation characteristics of the species, site and environmental factors, economic and procurement considerations, and construction schedules and goals. Favorable propagation conditions include proper and limited storage, fungicide dip, wounding, recut base, treatment with growth regulators, intermittent mist, sterile well drained media, bottom heat, shade, and strict environmental control. |
