The combustibility of four conifer-tree species in Xiaoxing’an Mountain, Heilongjiang Province was studied by cone calorimetric analysis. The four species were Pinus koraiensis Sieb.et Zucc、Pinus sylvestris var.mongolica Litv、Picea koraiensis Nakai、Larix gmelinii Rupr.. The thermal characteristics of leaves and barks, including smoke production rate(SPR)、specific extinction area(SEA)、the concentration of carbon dioxide (CO2)、the production of carbon dioxide ( PCO2 )、the concentration of carbon dioxide (CO)、the production of carbon dioxide ( PCO )were tested and recorded simultaneously.Th results showed that ,at a heat reflux of 50 kW•m-2, the values of SPR , SEA , the concentration of carbon dioxide (CO2) and the production of carbon dioxide (PCO) of Larix gmelinii Rupr. t had strong smoke inhibiting effect. Both Larix gmelinii Rupr. and Pinus koraiensis Sieb.et Zucc had strong smoke inhibiting effect, and Larix gmelinii Rupr. and Pinus koraiensis Sieb.et Zucc was most recommended as fire resistance species for fire-preventing forest belts.

To anticipate European climate scenarios for the end of the century, we explored the climate gradient within the REINFFORCE (RÉseau INFrastructure de recherche pour le suivi et l’adaptation des FORêts au Changement climatiquE) arboreta network, established in 38 sites between latitudes 37° and 57°, where 33 tree species are represented. We aim to determine which climatic variables best explain their survival and growth, and identify those species that are more tolerant of climate variation and those of which the growth and survival future climate might constrain. We used empirical models to determine the best climatic predictor variables that explain tree survival and growth. Precipitation-transfer distance was most important for the survival of broadleaved species, whereas growing-season-degree days best explained conifer-tree survival. Growth (annual height increment) was mainly explained by a derived annual dryness index (ADI) for both conifers and broadleaved trees. Species that showed the greatest variation in survival and growth in response to climatic variation included Betula pendula Roth, Pinus elliottii Engelm., and Thuja plicata Donn ex D.Don, and those that were least affected included Quercus shumardii Buckland and Pinus nigra J.F.Arnold. We also demonstrated that provenance differences were significant for Pinus pinea L., Quercus robur L., and Ceratonia siliqua L. Here, we demonstrate the usefulness of infrastructures along a climatic gradient like REINFFORCE to determine major tendencies of tree species responding to climate changes.

Smoke from forest fires can persist in the environment for weeks and while there is a substantial amount of literature examining the effects of smoke exposure on seed germination, the effects of smoke on leaf function are nearly uninvestigated. The objective of this study was to compare growth and primary and secondary metabolic responses of deciduous angiosperm and evergreen conifer tree species to short smoke exposure. Twenty minutes of smoke exposure resulted in a greater than 50% reduction in photosynthetic capacity in five of the six species we examined. Impairment of photosynthesis in response to smoke was a function of reductions in stomatal conductance and biochemical limitations. In general, deciduous angiosperm species showed a greater sensitivity than evergreen conifers. While there were significant decreases in photosynthesis and stomatal conductance, smoke had no significant effect on growth or secondary defense compound production in any of the tree species examined.
