Associations of calcium and aluminum with the growth and health of sugar maple trees in Vermont
We compared tree growth and crown condition with soil and foliar elemental composition in 14 sugar maple (Acer saccharumMarsh.) stands in VT, USA, to evaluate if deficiencies or imbalances in cation nutrition were associated with growth and health reductions in native stands. The Till Source Model (TSM) was used to select study sites potentially high or low in calcium (Ca) by predicting the rel...
متن کاملA Survey of Sugar Maple Nutrition in Vermont and its Implications for the Fertilization of Sugar Maple Stands
Can fertilization of sugar maple stands lead to increased diameter growth, better crown conditions, and/or added sugar production? We have wrestled questions like these for over a decade at research sites in northwest Vermont. Recently we have begun to expand our understanding of maple nutrition by examining stands in a wider geographic area. The effectiveness of fertilization depends in large ...
متن کاملLeaf nutrition and photosynthetic performance of sugar maple (Acer saccharum) in stands with contrasting health conditions.
Leaf nutrition and photosynthetic performance of sugar maple (Acer saccharum Marsh.) were compared between two sugar maple stands in northwestern Vermont with contrasting health conditions as indicated by annual basal area growth, degree of crown dieback, and foliar appearance. Observations made during the diurnal cycle of both stands showed no apparent leaf water stress. In both stands, leaves...
متن کاملExperimental branch cooling increases foliar sugar and anthocyanin concentrations in sugar maple at the end of the growing season
Autumnal leaf anthocyanin expression is enhanced following exposure to a variety of environmental stresses and may represent an adaptive benefit of protecting leaves from those stresses, thereby allowing for prolonged sugar and nutrient resorption. Past work has shown that experimentally induced sugar accumulations following branch girdling triggers anthocyanin biosynthesis. We hypothesized tha...
