Download Some Effects of Paraformaldehyde on Wood Surrounding Tapholes in Sugar Maple Trees Book in PDF, ePub and Kindle
S2Pills of paraformaldehyde (trioxymethylene) are commonly used in tapholes in sugar maple trees (Acer saccharum Marsh.) to increase the yield of sap collected for making syrup and sugar (2, 4, 5, 8). The explanation offered for this increase in sap yield is that microorganisms in the tapholes (7) cause premature decline and stoppage of the sap flow (1, 6), but that paraformaldehyde increases sap yield by inhibiting their growth (2). But what happens to the tree? To determine the effects of paraformaldehyde on the tissues surrounding tapholes, and on the microorganisms in those tissues, sugar maple trees were dissected and studied. This paper is a report on that study.S3.

Download Vacuum Pumping Increases Sap Yields from Sugar Maple Trees Book in PDF, ePub and Kindle
S2In the spring of 1967, a vacuum pump was installed at a sugarbush located in Underhill, Vermont. This work proceeded in two phases: an individual-tree study designed to determine if sap could be drawn out of a tree in sufficient quantities to account for large yield differences; and a large-scale study of the effects of sustained levels of vacuum on yields from a nearly commercial-size network of tubing.

Download Sap Yields from Fall and Spring Tapping of Sugar Maple Book in PDF, ePub and Kindle
S2Some maple sap producers have wondered whether they could increase the total sap yields by tapping their trees not only in the spring but also in the fall too. Our research indicates that tapping in the fall cannot be recommended. Our study of fall tapping was begun in November 1964. Fall tapping was at least theoretically possible because temperature fluctuations like those of the normal spring tapping season occur to some extent in late fall and early winter. However, it was not known whether the volume and sugar concentration of fall-produced sap would be adequate to make such a practice feasible. Nor did we know whether fall tapping would affect the normal spring sap production from fall-tapped trees. The study reported here was set up to answer these questions. S3.

Download Variation of Sugar Maple Sap Yield and Its Influence on Experimental Design Book in PDF, ePub and Kindle
S2When sap production research was begun by the Northeastern Forest Experiment Station in Burlington, Vermont, in 1964, it became apparent that more quantified information on sap yield variation among individual trees and among years was needed to facilitate the designing of efficient experiments. One of the first projects undertaken was to record seasonal sap yields on approximately 140 individual trees on a sugarbush near Jericho, Vermont. Yields were measured in the sap seasons of 1965, 1966, and 1967. Data presented in this report are based for the most part on a random sample drawn from these trees. All sample trees were tapped with two tapholes bored to a uniform depth.S3.

Download The Effect of Xylem Age on Volume Yield & Sugar Content of Sugar Maple Sap Book in PDF, ePub and Kindle
At the Burlington, Vermont, research unit of the Northeastern Forest Experiment Station, a study was begun in 1966 in an effort to identify the portions of the xylem that produce the most sap and the sap with the highest sugar content. The study revealed that the greatest volume of sap comes from xylem that is about 35 years old, and that the sweetest sap comes from the young xylem just beneath the bark.
