Temporal and spatial variations of shoot structural parameters, including shoot silhouette to projected needle area ratio, are very important, e.g., for the correction of leaf area index estimated by indirect methods. Here we bring few examples of their evolution within mountain spruce monoculture planted in two different densities.

Keywords: leaf area index; Picea abies
Subjects: growth analysis, plant development, biomass and yield enhancement; needle area, projected; Norway spruce, growth analysis, morphology; Picea abies; planting density, shoot morphology
