A 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 کاملA case of maple sugar urine disease.
Maple sugar urine disease is an inborn error of metabolism, in which the symptoms such as feeding difficulty, weak crying or irregular, jerky respirations occur soon after birth, consequently growth failure is brought about and finally the death comes mostly due to a complication of bronchopneumonia within several weeks or months of life.1) Outstanding features of the disease are known to be a ...
متن کاملStem girdling manipulates leaf sugar concentrations and anthocyanin expression in sugar maple trees during autumn.
To better understand the effects of sugar accumulation on red color development of foliage during autumn, we compared carbohydrate concentration, anthocyanin expression and xylem pressure potential of foliage on girdled versus non-girled (control) branches of 12 mature, open-grown sugar maple (Acer saccharum Marsh.) trees. Half of the study trees were known to exhibit mostly yellow foliar color...
متن کاملNondestructive Estimation of Anthocyanin Content in Autumn Sugar Maple Leaves
A field-portable tool for nondestructive foliar anthocyanin content estimation would be beneficial to researchers in many areas of plant science. An existing commercial chlorophyll content meter was modified to measure an index of anthocyanin content. The ability of the experimental anthocyanin meter (ACM) to estimate total extractable anthocyanin content was tested in sugar maple (Acer sacchar...
متن کاملEffect of measurement CO2 concentration on sugar maple root re
to predicting belowground C cycling in forest ecosystems. Inhibition of respiration has been reported as a short-term response of plant tissue to elevated measurement [CO2]. We sought to determine if measurement [CO2] affected root respiration in samples from mature sugar maple (Acer saccharum Marsh.) forests and to assess possible errors associated with root respiration measurements made at [C...
