“…Dependable allometric predictive equations based on branch-and tree-level dimensions can estimate foliage biomass and have been widely reported [49,50]. The foliar biomass allometric relationship is an important component for predicting growth and carbon circulation in many growth models [11,51]. The extent of observed foliage biomass is essential for evaluating the distribution of foliage within forest stands.…”

“…The distribution and amount of foliage biomass of individual trees within the entire crown determine tree and stand growth [7,8]. Foliage biomass distribution is also related to shade tolerance and stand density and exerts an evident influence on competitive interactions, crown asymmetry, and tree bole values [9][10][11]. Foliage biomass is generally recognized as concentrating vertically in the central part of the crown; moving down from the tree tip toward the crown base, it first increases and then decreases [12,13].…”

The characteristics and distribution of foliage biomass are important aspects of the crown structures of trees. In this study, we developed a foliage biomass distribution model at the branch level and annual shoot level (i.e., all branches on an annual increment of the main tree bole) using a sample of 51 Korean pine trees that were destructively sampled in Liaoning Province, northeast China. A variety of independent variables, including branches, trees, and forest competition, were used as explanatory variables in the model development. Our results indicated that foliage biomass at the branch level increased with an increasing relative distance from the tree tip into the crown. The peak of the foliage biomass distribution shifted to the tree tip with increasing tree age. A power function, including branch diameter and competition variables, showed excellent performance in modeling branch foliage at the branch level. The final model, which included branch diameter, competition variables, and relative distance to branch base for the relative foliage density, showed best performance. The trees that showed advantageous growth ability also had a larger amount of foliage biomass.

“…P. glauca and P. mariana originated from North America, and most of their allocation ranges overlap with each other. However, P. glauca mostly grows in nutrient-rich soil, while P. mariana mostly grows in soil with relatively poor nutrition [ 76 ]. Therefore, the contrasting growth performance of the two species may be related to the long-term adaptation to the environments of their original habitats.…”

Background Picea species are distributed and planted world-wide due to their great ecological and economic values. It has been reported that Picea species vary widely in growth traits in a given environment, which reflects genetic and phenotypic differences among species. However, key physiological processes underlying tree growth and the influencing factors on them are still unknown. Results Here, we examined needle structures, needle chemical components, physiological characteristics and growth traits across five Picea species in a common garden in Tianshui, Gansu province in China: Picea glauca, P. mariana, P. likiangensis, P. koraiensis, and P. crassifolia, among which P. glauca and P. mariana were introduced from North America, P. likiangensis was from Lijiang, Yunan province in China, P. koraiensis was from Yichun, Heilongjiang province in China, and P. crassifolia was native to the experimental site. It was found that nearly all traits varied significantly among species. Tissue-level anatomical characteristics and leaf mass per area (LMA) were affected by needle size, but the variations of them were not associated with the variations in photosynthetic and biochemical capacity among species. Variations in area-based maximum photosynthesis (Pnmax) were affected by stomatal conductance (gs), mesophyll conductance (gm) and biochemical parameters including maximum carboxylation rate (Vcmax), and maximum electron transport rate (Jmax). The fraction of N allocated to different photosynthetic apparatus displayed contrasting values among species, which contributed to the species variations in photosynthetic nitrogen use efficiency (PNUE) and Pnmax. Additionally, all growth traits were positively correlated with Pnmax and PNUE. Conclusion Needle structures are less important than needle biochemical parameters in determining the variations in photosynthetic capacity across the five Picea species. Pnmax and PNUE are closedly associated with the fraction of N allocated to photosynthetic apparatus (Pphoto) compared with leaf N content per area (Narea). The tremendous growth differences among the five Picea species were substantially related to the interspecies variation in Pnmax and PNUE.

“…In addition, low image-quality of scans required manual removal of shadows from each needle/image. Bigger trees are associated with higher foliage biomass and projected leaf area in spruce (POWER et al, 2014), but our study is among the few to assess genetic parameters for these traits. Leaf mass (LMR), which can be assessed with greater precision because it does not include leaf area, was less heritable than leaf area (LAR or SLA), and weakly correlated with growth traits, supporting the premise that leaf area is more related to growth than leaf mass.…”

White spruce is highly valued by the forest products industry in North America. Through tree improvement efforts, selected genotypes can exceed wild sources by 30% in volume. Negative correlations between growth and wood specific gravity have been established, but differences in leaf morphology between high and low performing genotypes are less well understood. We sampled five trees from each of 30 families at each of two locations in a 25-year old progeny test in Minnesota. One wood core was collected from each tree to sample wood specific gravity (WSG), along with a branch collected from the upper crown to examine foliar traits. We confirmed negative correlations between stem volume and WSG, but several families combined high wood volume with only small reductions in WSG. Leaf area ratio and specific leaf area were positively, genetically correlated with volume growth but not correlated with WSG. Increased growth rates of selected genotypes may be attributed, in part, to shifts in allocation to leaves and in leaf morphology that may optimize light interception.
