2nd World Conference on Biomass for Energy, Industry and Climate Protection, 10-14 May 2004, Rome, Italy EVALUATION OF THE COMBUSTION CHARACTERISTICS OF FOUR PERENNIAL ENERGY CROPS (ARUNDO DONAX, CYNARA CARDUNCULUS, MISCANTHUS X GIGANTEUS AND PANICUM VIRGATUM) Jonas Dahl & Ingwald Obernberger Institute of Resource Efficient and Sustainable Systems, Graz University of Technology, Inffeldgasse 25, A - 8010 Graz, Austria, Tel.: +43 (0)316 481300, Fax: +43 (0)316 481300 4; E-mail: [email protected] ABSTRACT: The perennial crops giant reed, switchgrass, miscanthus and cardoon were investigated in laboratory- scale and pilot-scale combustion test runs. Laboratory-scale test runs were conducted in a fixed bed pot reactor monitoring the temperature in the fuel bed and the release of gaseous components while pilot-scale test runs where conducted in a 150 kWth rotating grate fired combustion plant measuring formed emissions of CO, NOX, SO2, HCl, and particulates as well as performing deposit probe measurements. The results revealed that the high concentration of ash and slag forming elements such as Si, K and Ca cause severe problems regarding slagging if not specially considered during combustion. Moreover, high concentrations of N are another challenge regarding measures in order to avoid high emissions of NOx. Moreover, also HCl and SO2 emissions are considerably higher compared to wood fuels due to the higher concentrations of Cl and S in these fuels. Keywords: biomass characteristics, biomass conversion, cynara cardonculus, giant reed, switchgrass, miscanthus 1 INTRODUCTION combustion unit (nominal boiler capacity 150 kWth) were carried out with larger amounts (2-4 tons) of Due to the limited availability of wood fuels, in pelletised switch grass and chopped giant reed and southern Europe, high yield energy crops could give an chopped miscanthus (MI). -
Arundo Donax
FLORIDA NATIVE PLANT SOCIETY POLICY STATEMENT ON ARUNDO DONAX The Florida Native Plant Society opposes the agricultural production of Arundo donax (giant reed, e- grass, bamboo reed, arundo grass, giant bamboo reed, etc.) as a biofuel in Florida due to its invasive characteristics and empirical evidence of impact on native plant communities. The Society further encourages the eradication of existing stands of this species and the banning of its sale as an ornamental to prevent invasion of native plant habitats in Florida. ---Approved by the Board of Directors of the Florida Native Plant Society on October 28, 2006. BACKGROUND Arundo donax is a large, clumping grass species native to the Indian subcontinent and possibly to adjacent areas of Asia and eastern Europe. It has been spread across most tropical to warm-temperate regions of the globe for various reasons including but not limited to ornamental horticulture, erosion control, reed production for musical instruments, thatch, biomass production (biofuel), and building materials. Outside its native range, Arundo donax is believed to be sterile or nearly sterile and most if not all reproduction is by fragmentation of rhizomes and production of new roots from stems at nodes (Dudley, in press). It is found primarily in riverine habitats where it is broken up and spread during high water events (Else, 1996 as cited in Dudley, in press) and where, once introduced, it spreads vegetatively forming large, dense masses. A single clone can cover hundreds of acres (Pacific Island Ecosystems at Risk, 2005). Spread between riverine systems is rarely addressed in the literature with 1) rare viable seed, 2) movement on equipment, 3) deliberate introduction by humans, 4) and occasional movement of plant fragments by animals or humans being known or hypothesized. -
Molecular Identification of Commercialized Medicinal Plants in Southern Morocco
Molecular Identification of Commercialized Medicinal Plants in Southern Morocco Anneleen Kool1*., Hugo J. de Boer1.,A˚ sa Kru¨ ger2, Anders Rydberg1, Abdelaziz Abbad3, Lars Bjo¨ rk1, Gary Martin4 1 Department of Systematic Biology, Evolutionary Biology Centre, Uppsala University, Uppsala, Sweden, 2 Department of Botany, Stockholm University, Stockholm, Sweden, 3 Laboratory of Biotechnology, Protection and Valorisation of Plant Resources, Faculty of Science Semlalia, Cadi Ayyad University, Marrakech, Morocco, 4 Global Diversity Foundation, Dar Ylane, Marrakech, Morocco Abstract Background: Medicinal plant trade is important for local livelihoods. However, many medicinal plants are difficult to identify when they are sold as roots, powders or bark. DNA barcoding involves using a short, agreed-upon region of a genome as a unique identifier for species– ideally, as a global standard. Research Question: What is the functionality, efficacy and accuracy of the use of barcoding for identifying root material, using medicinal plant roots sold by herbalists in Marrakech, Morocco, as a test dataset. Methodology: In total, 111 root samples were sequenced for four proposed barcode regions rpoC1, psbA-trnH, matK and ITS. Sequences were searched against a tailored reference database of Moroccan medicinal plants and their closest relatives using BLAST and Blastclust, and through inference of RAxML phylograms of the aligned market and reference samples. Principal Findings: Sequencing success was high for rpoC1, psbA-trnH, and ITS, but low for matK. Searches using rpoC1 alone resulted in a number of ambiguous identifications, indicating insufficient DNA variation for accurate species-level identification. Combining rpoC1, psbA-trnH and ITS allowed the majority of the market samples to be identified to genus level. -
Common Reed Phragmites Australis (Cav.) Trin. Ex Steud. Grass Family (Poaceae)
FACT SHEET: GIANT REED Common Reed Phragmites australis (Cav.) Trin. ex Steud. Grass family (Poaceae) NATIVE RANGE Eurasia DESCRIPTION Common reed, or Phragmites, is a tall, perennial grass that can grow to over 15 feet in height. In North America, both native phragmites (Phragmites australis ssp. americanus Saltonstall, P.M. Peterson & Soreng) and introduced subspecies are found. Introduced Phragmites forms dense stands which include both live stems and standing dead stems from previous year’s growth. Leaves are elongate and typically 1-1.5 inches wide at their widest point. Flowers form bushy panicles in late July and August and are usually purple or golden in color. As seeds mature, the panicles begin to look “fluffy” due to the hairs on the seeds and they take on a grey sheen. Below ground, Phragmites forms a dense network of roots and rhizomes which can go down several feet in depth. The plant spreads horizontally by sending out rhizome runners which can grow 10 or more feet in a single growing season if conditions are optimal. Please see the table below for information on distinguishing betweeen native and introduced Phragmites. ECOLOGICAL THREAT Once introduced Phragmites invades a site it quickly can take over a marsh community, crowding out native plants, changing marsh hydrology, altering wildlife habitat, and increasing fire potential. Its high biomass blocks light to other plants and occupies all the growing space belowground so plant communities can turn into a Phragmites monoculture very quickly. Phragmites can spread both by seed dispersal and by vegetative spread via fragments of rhizomes that break off and are transported elsewhere. -

Ecology and Management of Arundo Donax, and Approaches to Riparian Habitat Restoration in Southern California
ECOLOGY AND MANAGEMENT OF ARUNDO DONAX, AND APPROACHES TO RIPARIAN HABITAT RESTORATION IN SOUTHERN CALIFORNIA. Gary P. Bell The Nature Conservancy of New Mexico, 212 E. Marcy Street, Suite 200, Santa Fe, NM 87501 USA Abstract By far the greatest threat to the dwindling riparian resources of coastal southern California is the alien grass species known as Arundo donax. Over the last 25 years the riparian forests of coastal southern California have become infested with A. donax which has spread by flood-fragmentation and dispersal of vegetative propagules. Arundo donax dramatically alters the ecological/successional processes in riparian systems and ultimately moves most riparian habitats towards pure stands of this alien grass. By current estimates there are tens of thousands of acres of A. donax along the major coastal drainage systems of southern California, including the Santa Ana, Santa Margarita, Ventura, Santa Clara, San Diego, and San Luis Rey rivers. The removal of A. donax from these systems provides numerous downstream benefits in terms of native species habitat, wildfire protection, water quantity and water quality. Introduction Arundo L. is a genus of tall perennial reed-like grasses (Poaceae) with six species native to warmer parts of the Old World. Arundo donax L. (giant reed, bamboo reed, giant reed grass, arundo grass, donax cane, giant cane, river cane, bamboo cane, canne de Provence), is the largest member of the genus and is among the largest of the grasses, growing to a height of 8 m (Fig. 1). This species is believed to be native to freshwaters of eastern Asia (Polunin and Huxley 1987), but has been cultivated throughout Asia, southern Europe, north Africa, and the Middle East for thousands of years and has been planted widely in North and South America and Australasia in the past century (Perdue 1958, Zohary 1962). -
An Armored Scale Released for Biological Control of Giant Reed, Arundo Donax

Armored scales (Hemiptera: Diaspididae) have not been used for biological weed control. However, over 250 armored scale species occur on grasses, of which 87% feed only on this family and 58% feed on only one grass genus, suggesting that armored scales may have unrealized biological control potential. We selected the armored scale Rhizaspidiotus donacis Leonardi as a candidate agent against the exotic, invasive, water-consuming grass known as giant reed (Arundo donax L.), based on literature records and our collections indicating host-specificity to the genus Arundo and its broad geographic range in the Mediterranean basin. -

Reed Instruments About Reeds
Reed Instruments About Reeds A reed is a thin elastic strip of cane fixed at one end and free at the other. It is set into vibration by moving air. Reeds are the sound generators in the instruments described below. Cane reeds are built as either double or single reeds. A double reed consists of two pieces of cane carved and bound into a hollow, round shape at one end and flattened out and shaved thin at the other. The two pieces are tied together to form an channel. The single reed is a piece of cane shaved at one end and fastened at the other to a mouthpiece. Single Reed Instruments Clarinet: A family of single reed instruments with mainly a cylindrical bore. They are made of grenadilla (African blackwood) or ebonite, plastic, and metal. Clarinets are transposing instruments* and come in different keys. The most common ones used in orchestras are the clarinet in A and the clarinet in Bb. When a part calls for a clarinet in A, the player may either double -i.e. play the clarinet in A, or play the clarinet in Bb and transpose* the part as he plays. During the time of Beethoven, the clarinet in C was also in use and players were expected to be able to play all three instruments when required. All clarinets are notated in the treble clef and have approximately the same written range: E below middle C to c´´´´ (C five ledger lines above the staff). Bass Clarinet: A member of the clarinet family made of wood, which sounds an octave lower than the Clarinet in Bb. -

Khellaf); [email protected] (M. Zerdaoui)) RÉSUMÉ Pour déterminer la tolérance et la capacité de phytoaccumulation du cuivre (Cu) et du nickel (Ni) par une espèce de lentilles d’eau, Lemna gibba L., les plantes sont exposées à différentes concentrations de Cu et Ni (0,1 à 2,0 mg/L) dans une solution de Coïc et Lesaint dilué à 1/4. Le pH est maintenu constant à 6,0 (± 0,1) et le flux de lumière est de 12 h/jour. Le cuivre et le nickel sont tolérés par L. gibba à des concentrations ≤ 0,3 mg/L et ≤ 0,5 mg/L, respectivement. Cependant, la croissance des plantes diminue de 50% (I50) quand le milieu de culture contient 0,45 mg/L de Cu ou 0,75 mg/L de Ni. La plus faible concentration causant une inhibition complète (LCI) est de 0,5 et 1,0 mg/L respectivement en présence de Cu et Ni. Les résultats de l’analyse du métal dans les tissus des plantes révèlent une grande accumulation de Cu et une faible accumulation de Ni dans les tissus végétaux (pour la concentration ne causant aucune inhibition dans la croissance). Une diminution de la concentration de métal dans l’eau est également observée. -

Guide to Bassoon Reed Making
Guide to Bassoon Reed Making February 13, 2021 Bassoon Professor Elizabeth Low-Atwater [email protected] 1 Arundo Donax From the Wikipedia Page: Arundo donax, giant cane, is a tall perennial cane. It is one of several so-called reed species. It has several names including carrizo, arundo, Spanish cane, Colorado river reed, wild cane, and giant reed. Arundo donax grows in damp soils, either fresh or moderately saline, and is native to the Mediterranean Basin and Middle East, and probably also parts of Africa and the southern Arabian Peninsula. Tube Cane Cane is selected based on its diameter thickness of 24-26mm and is measured with a caliper tool. After cut to the correct lengths, the cane then sits for an average of 1 to 2 years to cure. 2 Steps from Cane to Finished Reed There are essentially six stages of the reed making process. We will dive into each of the steps specifically but laid out they are: 1. Gouged 2. Shaped 3. Profiled 4. Formed Tube (Cocoons) 5. Blank: Wired/Sealed/Turbaned 6. Finished Reed: Cut tip & Scraped 3 Split and Gouged Cane From the tube cane, it is then split into 3 to 4 pieces soaked overnight, and taken through a pre-gouger and gouger to remove the inside soft parts of the cane. Pre Gouger Gouger Shaping In this process, the gouged piece of cane is soaked for 2-3 hours then placed into a straight shaper. The metal shaper helps act as a guide to cut out the given shape. This is done with a ceramic knife, x-acto knife, and a diamond file.
