Delays in the start of growing season reduce period available for growth and amount xylem production. However, a higher number developing tracheids could prolong cell differentiation and, consequently, lengthen season. The relationship between duration production remains an unresolved issue. aim this study was to resolve chicken-or-egg causality dilemma about through simple- double-cause models. This achieved by (1) analysing intra-annual dynamics Picea mariana (Mill.) BSP during 2006-2009...
In boreal ecosystems, an increase in soil temperature can stimulate plant growth. However, cambium phenology trees was better explained by air than temperature, which suggested that is not the main limiting factor affecting xylogenesis. Since and snowmelt are correlated to question whether directly limits xylogenesis stem will remain unresolved without experiments disentangling temperatures. This study investigated effects of 4 °C a consequent 1-week earlier on growth black spruce [Picea...
Since plant growth in the boreal forest is often considered to be limited by low temperatures and N availability these variables are projected increase due climate warming increased anthropogenic activities, it important understand whether what extent disturbances may affect of trees. In this study, hypotheses that wood phenology anatomy were affected soil depositions have been tested two mature black spruce ( Picea mariana (Mill.) BSP) stands at different altitudes Quebec, Canada. For 3...
This manuscript aims to evaluate the precision and accuracy of current methodology for estimating xylem phenology tracheid production in trees. Through a simple approach, sampling at two positions on stem co-dominant black spruce trees sites boreal forest Quebec, we were able quantify variability among sites, between within tree different variables. We demonstrated that is accurate estimation onset xylogenesis, while evaluation ending xylogenesis may be improved by multiple stem. The pattern...
Black spruce is one of the main commercial species in boreal forests North America. It usually forms large and single-species natural stands eastern Canada, yet recent years, parts this area have undergone forest cover regression conversion closed-crown to open lichen woodlands, partly due successive disturbances regeneration accidents. We studied two post-fire cohorts growing at same site, for which a clear trajectory has already been demonstrated, assess possible changes site potential....
