“…The causal relationship between cell production and the timings of growth cessation found in this work allowed clarification of some mechanisms of tree-ring formation and the observations that younger, vigorous, or fertilized trees produced more cells and showed later cessation of growth (Peltola et al 2002;Deslauriers et al 2003;Schmitt et al 2003). In boreal and temperate forests, temperature mainly affects cell production in spring and early summer, during the first part of the growing season.…”

“…La relation causale entre la production cellulaire et la date de fin de la croissance radiale mise en évidence dans cette thèse (Chapitre II) a fourni une nouvelle clé d'interprétation de certains mécanismes de formation du cerne de croissance et des observations que les arbres plus jeunes, vigoureux ou fertilisés produisent plus de cellules et terminent plus tard leur croissance (Peltola et al 2002, Deslauriers et al 2003, Schmitt et al 2003. La production plus élevée en terme de bois observée dans les arbres plus jeunes (Rossi et ah 2008a) ou à des plus basses altitudes et latitudes , Rossi et al 2011b) devrait donc allonger la période requise pour compléter la maturation du xylème, prolongeant ainsi la période de formation du bois.…”

Remerciements"The thing the ecologically illiterate don't realize about an ecosystem is that it's a system. A system! A system maintains a certain fluid stability that can be destroyed by a misstep in just one niche. A system has order, a flowing from point to point. If something dams the flow, order, collapses. The untrained might miss that collapse until it was too late. That's why the highest function of ecology is the understanding of consequences."Parclot Kynes in "Appendix I: The Ecology of Dune", in the science fiction novel "Dune", written by Frank Herbert Per ultimo, ma non per importanza, La miafamiglia. Voglio in particolare ricordare mia nonna Anna, i miei genitori, Leonello e Nives, e mio fratello Roby, che mi hanno sostenuto e consigliato. RésuméLa croissance des arbres dans la forêt boréale est souvent considérée limitée par les basses températures et par la disponibilité en azote (N). Avec le réchauffement climatique, la disponibilité en azote pourrait augmenter grâce à l'effet positif d'une augmentation de la température du sol sur la minéralisation et la décomposition de la matière organique. De plus, les dépôts azotés d'origine anthropique ont grandement altéré le cycle de l'azote et la nutrition des plantes dans les deux derniers siècles et ils devraient augmenter dans le futur. Il est donc primordial de comprendre si, et dans quelle mesure, les perturbations d'origine anthropique (réchauffement climatique et augmentation de dépôts azotés) peuvent influencer la croissance de la forêt boréale. Le but de cette thèse a été de comprendre de quelle manière la formation du cerne ligneux et la productivité en termes de bois chez Pépinette noire (Picea mariana (Mill.) BSP) pourraient varier dans le futur sous l'influence des perturbations d'origine anthropique évoquées ci-dessus. La recherche a eu lieu en forêt boréale dans deux peuplements équiennes constitués d'épinettes noires adultes, dans la région du Saguenay-Lac-St-Jean, au Québec (Canada). Premièrement, nous avons déterminé les dynamiques actuelles de formation du cerne de croissance chez l'épinette noire, afin de pouvoir décrire d'éventuelles différences entre les deux sites et connaître l'impact de la variabilité climatique interannuelle (Chapitre II). Ces résultats nous ont permis de développer un modèle qui analyse la relation entre la phénologie et la productivité du cerne de croissance dans les conditions actuelles. Ce modèle, en plus de fournir une nouvelle clé d'interprétation de la xylogenèse dans les conditions actuelles, a permis d'interpréter de façon plus approfondie les résultats d'une expérience de manipulation de la température du sol et des dépôts azotés (Chapitres III et IV) simulant les conditions attendues pour le futur.Dans les deux sites étudiés la dynamique de formation du cerne de croissance était similaire. Toutefois, la différence entre les sites, d'environ deux à trois semaines, dans la date de fonte de la neige, se reflétait par un délai d'une à deux semaines dans le début de l'activité cambiale observé dans...

“…In our work, the standard X-ray intensity (30 kV, 35 mA) for X-ray measurements was used. An exposure time of 20 ms was selected based on previous work by Kilpeläinen et al (2005) and Peltola et al (2007).…”

“…In these conditions, the growth of individual trees and the formation of wood properties such as wood density and fibre characteristics are mainly affected by a relatively short growing season and fairly low summer temperatures (Leikola 1969, Peltola et al 2002, Kilpeläinen et al 2005. In these circumstances, the total stem wood production can be increased only by increasing either the rate of biomass production or the proportion of biomass allocated to the stem (Cannell 1978).…”

In recent years there has been increased interest in the so called narrow crowned Norway spruce (Picea abies f. pendula), which is a rare mutant of Norway spruce (Picea abies (L.) Karsten), as a suitable wood raw material source for pulp and paper production. This is because it is less sensitive to competition than the normal crowned Norway spruce, and thus, could be more productive especially at dense spacing. In the above context, we investigated how the growth and yield (such as height, diameter, stem volume and ring width) in addition to wood density traits and fibre properties (such as wood density, fibre length and width, cell wall thickness and fibre coarseness) were affected in trees from 9 full-sib families representing narrow crowned Norway spruce grown at narrow spacing of 1 m × 1 m in Southern Finland. For comparison, we used normal crowned Norway spruce trees from 6 breeding regions.We found that, compared to growth and yield traits, wood density traits and fibre properties showed, on average, lower phenotypic variations. In addition, these variations were smaller for narrow crowned families than for normal crowned genetic entries. Narrow crowned families also showed, on average, higher growth and yield and fibre length, but lower wood density. Moreover, the phenotypic correlations between growth, yield, wood density traits and fibre properties, ranged, on average, from moderate (narrow crowned) to high (normal crowned). As a whole, the growth and wood properties of narrow crowned families were found to be less sensitive to tree competition than the normal crowned genetic entries used as a comparison.

“…C3 High Pinus sylvestris (20-year trees) increased in diameter earlier in the season and stopped growing later when exposed to elevated temperatures (compared with ambient temperatures), and diameter was 26 % greater in elevated temperatures vs ambient temperatures over the 3-year study [250]. Elevated temperatures did not significantly alter net photosynthesis across the native range of Pinus taeda [251].…”

Stress-Tolerant Feedstocks for Sustainable Bioenergy Production on Marginal Land

et al. 2015

Given the mandated increases in fuel production from alternative sources, limited high-quality production land, and predicted climate changes, identification of stress-tolerant biomass crops will be increasingly important. However, existing literature largely focuses on the responses of a small number of crops to a single source of abiotic stress. Here, we provide a much-needed review of several types of stress likely to be encountered by biomass crops on marginal lands and under future climate scenarios: drought, flooding, salinity, cold, and heat. The stress responses of 17 leading biomass crops of all growth habits (e.g., perennial grasses, shortrotation woody crops, and large trees) are summarized, and we identify several that could be considered "all purpose" for multiple stress types. Importantly, we note that some of these crops are or could become invasive in some landscapes. Therefore, growers must take care to avoid dissemination of plants or propagules outside of cultivation.
