Sap sweetness consistency vs. growth rates in young sugar maples
1990
Laing, F.M. | Howard, D.B.
Mature sugar maples have been shown in a previous study to be consistent for sap sweetness when ranked against other trees in a population for many years. This study examined sap sweetness in young sugar maples in relation to basal area growth rates. A definite trend toward consistency for sap sweetness was found in young trees although there was greater variability than in mature trees. Reasons for this variability are postulated to be the continuing competitive growth of the younger trees and mortality due to natural causes and/or management. However, the trend toward consistency for sweetness warrants sap testing as a criterion in selecting potential crop trees for sap production. Annual correlations between sap sweetness and growth rates varied with no clear trend.
