Dip into the history and science of this sweet treat. A Long-standing Tradition Native Americans were the first to make maple sugar. Perhaps inspired by animals licking sweet sap from the trees, they began collecting it and boiling it down to concentrate the sugar. They taught this process to European colonists, who enthusiastically adopted it; nearly every farmer had some maple trees for tapping. Over time, most producers shifted their focus from sugar to syrup, in part because the introduction of canning at the end of the 1800s made it possible to preserve maple syrup. It Starts with Sap Maple syrup and sugar come from concentrated sap, which consists of water with sugars and other nutrients. In deciduous trees—those that lose their leaves every fall—this sap travels up from the roots to feed the opening buds before the leaves are large enough to make their own food. All maples produce sap that can be used for syrup, but the quantities, flavor compounds, and sugar content vary. The sugar maple (Acer saccharum) yields sap with the most sugar and best flavor. The Climate Connection Maple sap can only be collected in useful quantities when conditions are right. Producers need a several-week-long period of cold, followed by daytime temperatures at or above 40°F and nights that are below freezing. These conditions cause a steady flow that may last for several days. The sap can be gathered until nighttime temperatures are consistently too warm. Traditionally, the sugaring season in Massachusetts took place between February and early April, but it has been getting earlier and shorter over the years as the climate has changed. With the continued shift in climate, there may come a time when sugaring is no longer feasible Maple Grove at Ipswich River, Topsfield in Massachusetts. 3 Making Syrup Make Your Own Once the sap has been collected, it must be boiled down Ready to try tapping your own trees? Here are the basics; to remove water, concentrate the sugar, and enhance the visit the Audubon Shop in Lincoln for books that provide flavor compounds. Maple sap contains just 1.5 to 3 percent detailed instructions. You’ll need a drill, a spile (the spout that sugar, but maple syrup is 66 to 67 percent sugar; it takes at fits in the hole), and containers to collect the sap. To minimize least 40 to 50 gallons of sap to make one gallon of syrup! The impact on the tree, use the newer small-diameter (5/16 of an traditional method of boiling inch) spiles. Hang a clean container on the spile and has long been suspending a large empty it at least once a day. Like milk, sap will spoil if it open pan over a wood fire. Most is left out, so store it in a cold place and boil it as soon as commercial sugar houses now you can.

The study includes a representative fraction (presumably about 80%) of the known species diversity of the Umbilicariaceae s.str. and is based on the phylograms obtained using maximum likelihood and a Bayesian phylogenetic inference framework. The analyses resulted in the recognition of eight well-supported clades, delimited by a combination of morphological and chemical features. None of the previous classifications within Umbilicariaceae s.str. were supported by the phylogenetic analyses. The distribution of the diagnostic morphological and chemical traits against the molecular phylogenetic topology revealed the following patterns of evolution: (1) Rhizinomorphs were gained at least four times independently and are lacking in most clades grouping in the proximity of Lasallia. (2) Asexual reproductive structures, i.e., thalloconidia and lichenized dispersal units, appear more or less mutually exclusive, being restricted to different clades.

  • Replacing Table Sugar with Maple Sugar by STEPHEN CHILDS
    Cornell Maple Bulletin 205 (2007) Replacing Table Sugar with Maple Sugar by STEPHEN CHILDS Balancing Balancing ingredients Ingredients Replacing granulated cane or beet sugar in recipes with maple syrup should be a growing trend. Guidelines about sugar replacement are different in different sources. It is easy to understand this confusing situation when you realize there are actually two ingredients that need to be balanced. When replacing granulated sugar in a recipe with maple syrup you should consider both the sugar balance and the liquid balance of the recipe. Some recommendations say to add 1 ! cup of syrup to replace one cup of sugar, others say to replace one cup of sugar with " cup of maple syrup. One is trying to balance the liquid in the recipe, the other the sweetness. The most straightforward approach is to simply replace one cup of granulated cane sugar with one cup of granulated maple sugar. In this case you gain the extra flavors from maple while the sweetness and the liquid stay in balance. I would especially suggest this where the recipe is depending on the qualities of milk or another liquid that you may be reducing to perform some important function in the recipe beyond what simply using water would accomplish. Liquid vs. Dry Liquid vs. Dry One cup of maple syrup at a fairly common density of 67º Brix provides 7.5 ounces (214 grams) of sugar and 3.7 ounces (105 grams) of water. One cup of cane sugar averages about 7.4 ounces (210 grams) of sugar. This is roughly the same amount sugar in a cup of maple syrup as in a cup of granulated sugar.

Total number of genera in the database: 526 Anamorphic fungi (see p. 4), which are disseminated by propagules not formed from cells where meiosis has occurred, are presently not grouped by class, order, etc. Most propagules can be referred to as "conidia," but some are derived from unspecialized vegetative mycelium. A significant number are correlated with fungal states that produce spores derived from cells where meiosis has, or is assumed to have, occurred.

    Cornell Maple Program 2019 – 2020 ANNUAL REPORT Cornell University Department of Natural Resources Authored by: Stephen Childs, Ailis Clyne, Aaron Wightman and Adam Wild 1 Program Overview Supporting the Maple Products Industry The Cornell Maple Program conducts research and extension with the goal of improving the production and use of maple products. Work toward this objective takes place in three parts: 1) infrastructure upgrades that create and enhance capacity in our two maple facilities 2) applied research on a broad array of topics related to maple production and profitability and, 3) extension programming to share knowledge across the industry. The Cornell Maple Program consists of maple specialists and technical support staff located at two facilities who work with a network of industry allies to deliver educational content. The Arnot Research Sugarbush near Ithaca, NY and the Uihlein Maple Research Forest in Lake Placid, NY include a combined capacity of over 14,000 taps in 350 acres of sugarbush, as well as modern processing equipment and research kitchen space. These two research and production facilities provide opportunities for experiments that account for region-wide variability in sugarbush conditions. Research sugarhouses at Arnot Forest in Van Etten, NY (left) and Uihelin Forest in Lake Placid, NY (right). 2 Program Highlights Sugarbush Management Super Sweet Trees Continuing the legacy of the “super sweet” maple tree project at the Uihlein Research Forest, we are in the middle of a three year project funded by McIntire Stennis federal capacity funds to re-analyze the potential sap sweetness and volume from our “super sweet” maple plantations.

  • Photobiont Associations in Co-Occurring Umbilicate Lichens with Contrasting Modes of Reproduction in Coastal Norway
    The Lichenologist 48(5): 545–557 (2016) © British Lichen Society, 2016 doi:10.1017/S0024282916000232 Photobiont associations in co-occurring umbilicate lichens with contrasting modes of reproduction in coastal Norway Geir HESTMARK, François LUTZONI and Jolanta MIADLIKOWSKA Abstract: The identity and phylogenetic placement of photobionts associated with two lichen-forming fungi, Umbilicaria spodochroa and Lasallia pustulata were examined. These lichens commonly grow together in high abundance on coastal cliffs in Norway, Sweden and Finland. The mycobiont of U. spodochroa reproduces sexually through ascospores, and must find a suitable algal partner in the environment to re-establish the lichen symbiosis. Lasallia pustulata reproduces mainly vegetatively using symbiotic propagules (isidia) containing both symbiotic partners (photobiont and mycobiont). Based on DNA sequences of the internal transcribed spacer region (ITS) we detected seven haplotypes of the green-algal genus Trebouxia in 19 pairs of adjacent thalli of U. spodochroa and L. pustulata from five coastal localities in Norway. As expected, U. spodochroa associated with a higher diversity of photobionts (seven haplotypes) than the mostly asexually reproducing L. pustulata (four haplotypes). The latter was associated with the same haplotype in 15 of the 19 thalli sampled. Nine of the lichen pairs examined share the same algal haplotype, supporting the hypothesis that the mycobiont of U. spodochroa might associate with the photobiont ‘pirated’ from the abundant isidia produced by L. pustulata that are often scattered on the cliff surfaces. Up to six haplotypes of Trebouxia were found within a single sampling site, indicating a low level of specificity of both mycobionts for their algal partner. Most photobiont strains associated with species of Umbilicaria and Lasallia, including samples from this study, represent phylogenetically closely related taxa of Trebouxia grouped within a small number of main clades (Trebouxia sp., T.

  • The Sugar Maple Acer Saccharum
    The Sugar Maple Acer Saccharum Cris Soliman & Hanna Barnes OEB59-- Plants and Human Affairs Botanical information The sugar maple is one of 148 maple species found in North America, of which 90 are native. The sugar maple is notable for the following 1 characteristics : ● Mature trees range in height from 70-90 feet, with an average diameter of 2-3 feet. ● Leaves are simple and single, with five lobes. The boundaries between the lobes are smooth and shallow (1a), helping to distinguish it from the red maple. ● Leaves and buds are in an opposite arrangement (1d). ● Terminal buds are typically larger than lateral buds (1d). ● Twigs are covered in lenticels-- small openings in the bark. ● Mature bark appears to have ‘plates’ that peel along the long edge. ● Monoecious-- female and male flowers on the same plant (1b, c). ● Fruit is a double samara (1e), meaning it has a characteristic winged shape. ● Massive quantities of fruits are produced cyclically, usually every two to five years, after the tree matures at age thirty. ● Small pores that are uniformly spaced (diffuse-porous). Distribution: ● From Nova Scotia and Quebec in the northeast, west to Minnesota and south to Tennessee. 1. Luzadis, V.A. & Gossett, E.R. (1996). Sugar Maple. In J.P. Lassoie, V.A. Luzadis, and D.W.
