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.

Comparing Perceptions of Native Status / Steven E. Smith in Native Plants Journal, 2 (1) (2001) 

Public Citation [article]  inNative Plants Journal > 2 (1) (2001) . - 5-11 Titre : Comparing Perceptions of Native Status Type de document : Imprimé Auteurs : Steven E. Smith ; Susan R. Winslow Année de publication : 2001 Article en page(s) : 5-11 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Revégétalisation Résumé : Use of the term “native” when referring to plants is common in many settings. However, what “native” means to different individuals and groups is often poorly understood. Inconsistent definition of native status (“nativity”) may complicate implementation or endorsement of conservation activities, particularly those involving revegetation. Professionals in plant-related fields are typically responsible for developing revegetation projects as well as regulations that apply to these projects. To assess how definition criteria may differ between groups we developed a questionnaire that asked respondents to assess native status in 13 hypothetical revegetation scenarios. A total of 303 questionnaires were evaluated with respondents from 33 states. Different respondent groups responded differently in certain scenarios. Where differences existed, professionals in plant-related fields were more likely to regard plants native than non-professionals. Respondents associated with Native Plant Societies (NPS) were less likely to designate plants as native than non-NPS respondents. Successful conservation activities with native plants should involve open and precise definition of nativity.
