The impact of seeds provenance and nursery provenance method on Austrian pine (Pinus nigra Arn.) seedlings quality
Keywords:Austrian pine, Pinus nigra, seedlings, containers, seedling quality.
AbstractThe influence of seed provenances and seedling production methods on quality of one and two years old seedlings of Austrian pine were investigated. Seeds from three provenances of Austrian pine (Goc, Studenica and Sargan) were used for seedlings production, combined with three production methods: (i) the modified seedbeds (bare-root), (ii) the container type Plantagrah II and (iii) the container type Gocko. Provenance, as well as the combined influence of provenance and production method had minimal influence on the variability of one and two years old Austrian pine seedlings. Nevertheless, the production method had the highest influence. The production system, besides its importance in nursery, will have a high influence on seedlings growth during the first year after planting. Considering the results of this study (e.g. the highest values of the diameter, number of lateral roots, shoot and root dry weight, and quality index and the lowest value of SQ and satisfactory value of S:R), we can conclude that the seedlings produced in container type Gocko led to the highest seedlings quality, recommended especially for afforestation on hard sites.
