Relationships Between Soil Salinity, Sap- Sugar Concentration, and Health of Declining Roadside Sugar Maples (Acer saccharum)
A study of 50 sugar maples {Acer saccharum) along Gates Mills Boulevard in Gates Mills, Ohio, showed that a tree's sap-sugar concentration tended to increase with decreasing tree health and increasing soil salt concentration. Relative tree health was determined by growth ring analysis. Salt concentration in soil was determined by measuring soil extract conductivity. Extract conductivity correla...
متن کامل"salty" Syrup from Roadside Sugar Maples in Decline
M.F. MORSELLI and M.L. WHALEN Maple Research Laboratory Botany Department College of Agriculture and Life Sciences University of Vermont October 1987 FINAL REPORT We had two objectives in the study of sugar maples which showed signs of decline and stress on a roadside where deicing salt was used in the winter. One goal was to determine If tree stress is related to the levels offsodium and chlor...
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 کاملThe evaluation of Agro climatic potentials of Kermanshah and Isfahan provinces in autumn cultivation of sugar beet
Since the most important climatic parameter affecting sugar beet cultivation is the temperature, we carried out this research considering climatic elements such as temperature, precipitation and freezing days in relation to autumn sugar beet planting. Daily temperatures of selected stations in a period of 10 years (2005-2015) has been used for agroclimatic analysis. In order to evaluate that, t...
