Public Citation est un extrait de Proceedings high altitude revegetation workshop n° 13 / Warren R.

Reid Année de publication : 1999 Importance : p. 105-117 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Revégétalisation 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.

Native Plant and Seed Production for High Elevation Restoration: Growing high elevation species in a northern plains desert / Joseph D. Scianna (2001) 

Public Citation contenu dans Native Plant: Propagation and Restoration Strategies / Robin Rose (2001)   Titre : Native Plant and Seed Production for High Elevation Restoration: Growing high elevation species in a northern plains desert Type de document : Extrait d'ouvrage Auteurs : Joseph D. Scianna Année de publication : 2001 Importance : 55-62 Langues : Français (fre) Catégories : [CBNPMP-Thématique] Revégétalisation Résumé : Producing high elevation plants under arid, low elevation conditions presents several challenges including heavy textured soils, desiccating winds and open winters. Methods of reducing soil crusting and improving seedling emergence include using vermiculite or rice hulls during seeding, rolling, and light, frequent irrigation with sprinklers during germination and establishment. Snow fence creates additional winter cover to protect seed production fields. Seed harvesting of small-stature and/or indeterminate species is maximized by hand harvesting, cyclic stripping or vacuuming, or windrowing, all followed by after-ripening. Summer cuttings are a viable alternative for container production.
