Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1989 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2Attempts to correlate ray tissue as a percentage of total wood volume with sap sugar concentrations of sugar maple progenies were unsuccessful. These results raise doubts about our ability to use a relatively constant value such as ray-tissue volume in a selection program designed to increase the sap-sugar concentration of sugar maple seedlings.

Download or read book Sap Yields from Fall and Spring Tapping of Sugar Maple written by Melvin Ray Koelling and published by . This book was released on 1968 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: S2Our recent studies of maple sap production have shown that invented tubing collection systems yield more sap than vented tubing systems, and that these increases are related to natural vacuum that develops in the unvented systems. Application of additional vacuum with a vacuum pump produced a further increase in sap yield. In these studies we used a paired-taphole type of experimental design. Two tapholes were drilled 6 inches apart on the same tree; one taphole of each pair received one treatment (vacuum) while the other was a control (no vacuum).S3.

Download or read book Carbohydrate Reserves and Growth Response in Sugar Maple Acer Saccharum Marsh Under Two Levels of Spring Xylem Sap Extraction written by Mark Louis Isselhardt and published by . This book was released on 2012 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual method for estimating root starch concentrations was adapted and evaluated for use with spring sugar maple twig tissue. The method of iodine-staining starch contained in xylem tissue was compared with starch detennined with the chemical method. There was little agreement between the two methods detennination of starch content. The highly dynamic nature of spring starch concentrations could help explain the result. Overall, the results of this work reveal no substantial threat to sugar maple growth or stored carbohydrates due to modem vacuum sap extraction and corresponding increases in NSC removal.
