Associated Forest Cover ( Anglèis )

fornì da Silvics of North America
Sites preferred by Carolina silverbell, the most mesic with the best soils, are those on which a number of hardwoods reach their best development. Consequently, it is found in association with a large number of hardwood species as well as occasionally with conifers.

In Piedmont areas, the species is associated with yellow-poplar (Liriodendron tulipifera), white ash (Fraxinus americana), red maple (Acer rubrum), white oak Quercus alba), American holly (Ilex opaca), eastern redbud (Cercis canadensis), and bigleaf magnolia (Magnolia macrophylla). In the southern part of its range it occurs with American beech (Fagus grandifolia), southern magnolia (M. grandiflora), American holly, various oaks, cabbage palmetto (Sabal palmetto), Florida maple (Acer barbatum), eastern hophornbeam (Ostrya virginiana), and eastern redbud (4). In the Black Mountains of North Carolina, Carolina silverbell is a significant associate in the northern hardwoods climax association at high elevations and in the cove climax and mesic slope associations at mid-elevations (10). It occurs and may share canopy dominance with eastern hemlock (Tsuga canadensis), yellow buckeye (Aesculus octandra), white basswood (Tilia heterophylla), sugar maple (Acer saccharum), and yellow birch (Betula alleghaniensis) in the Great Smoky Mountains and the Joyce Kilmer Memorial Forest (20,24,25,35). Prominent associates of the species in a gorge in the Blue Ridge Mountains of western North Carolina were northern red oak Quercus rubra), chestnut oak (Q. prinus), sweet birch (Betula lenta), yellow-poplar, flowering dogwood (Cornus florida), and Fraser magnolia (Magnolia fraseri).

Carolina silverbell is associated with the following forest cover types (Society of American Foresters) (13):

23 Eastern Hemlock

Climate ( Anglèis )

fornì da Silvics of North America
The climate over the range of Carolina silverbell is superhumid in the southern Appalachians and humid in the other areas, with temperatures that vary considerably with latitude and elevation. Average annual precipitation varies between 1020 mm and 1140 min (40 and 45 in) in the northern part of the range to more than 2030 min (80 in) in the southern Appalachians. Precipitation is well distributed over the year. Average January temperatures range from -1° to 13° C (30° to 55° F) and average July temperatures range from 21° to 27° C (70° to 80° F). The average annual maximum temperatures range from 32° to 41° C (90° to 105° F) and the average minimum from -4° to -21° C (25° to -50 F).

Flowering and Fruiting ( Anglèis )

fornì da Silvics of North America
Carolina silverbell has perfect flowers which appear as the leaves begin to expand in March to May, depending upon location (8,24,30). Each flower has a four-celled ovary, but usually only one cell produces a viable seed (15,17). Larger flower crops are produced annually after the 20th to 25th year (17). The fruit is a dry, oblong, four-winged drupe that matures in the fall.

Genetics ( Anglèis )

fornì da Silvics of North America
The first published description of Carolina silverbell appeared in 1731 in Mark Catesby's Natural History of Carolina (17). Linnaeus made a taxonomic description of it in 1759 and named it Halesia carolina L. There is evidence that the specimen used by Linnaeus may have been a different species; nevertheless, Halesia carolina is the name currently accepted. The genus has two other species with limited distribution in the southeastern and southern Piedmont and Coastal Plain. They are H. parviflora Michx. and H. diptera Ellis. All have n=12 chromosomes (7,9,27,31).

No studies on population differences in this species have been reported. However, its wide and discontinuous distribution likely has produced significant variation among and within populations over its range.

The large form of Carolina silverbell that grows in the southern Appalachian Mountains was at one time considered to be a separate species from the smaller form that occupies the rest of the range. It was given the name H. monticola (Rehd.) Sarg. but it differs from the smaller form only in size, and recent authors consider it synonymous with H. carolina (7,11,20,34).

Intergradation between H. carolina L. and H. parviflora Michx. (little silverbell) is suspected in the northern Coastal Plain where their distributions overlap (7).

Growth and Yield ( Anglèis )

fornì da Silvics of North America
Over most of its range, Carolina silverbell (fig. 3) is an understory shrub or small tree usually reaching heights of 6 to 12 in (20 to 40 ft) with a crown spread of 4.5 to 9 in (15 to 30 ft) and stem diameters of 12 to 27 cm (5 to 11 in). On good sites in the Great Smoky Mountains, however, some trees reach 30 m (100 ft) in height and 90 cm (36 in) in d.b.h. Only on cove and north slope sites in the mountains do trees of this species maintain crown positions in the upper canopy and reach large sawtimber size (8,12,23,24). Growth rates of individual trees are moderate to slow, the smaller ones showing 6 to 9 rings per centimeter (15 to 23/in) (12,17,24). No data are available on volumes per unit area, but the species could be expected to contribute significant volumes to the mixed hardwood stands only on the best sites in the mountains. Estimated total cubic volumes in 1980 in the mountains of three States are as follows (19):

Reaction to Competition ( Anglèis )

fornì da Silvics of North America
Carolina silverbell grows as an understory tree over most of its range and as a codominant in the mountains. It is classed as a shade-tolerant tree. A moist, loamy, partially shaded soil makes the best seedbed for either natural or artificial regeneration, although the species has been found with mixed hardwoods which regenerated a large, burned area in eastern Tennessee (7,23,24,26). In hemlock stands in western North Carolina, the species occurred with greater frequency on areas without a rhododendron cover than with (25). It competes well with other species regenerating in gaps left by treefalls in Southern Appalachian forests (29,36).

Seed Production and Dissemination ( Anglèis )

fornì da Silvics of North America
Large seed crops are produced annually by older trees of Carolina silverbell but much of the seed is sterile. The fruits are persistent and dissemination occurs well into the winter. The seeds are dormant to varying degrees at maturity and require special handling to break the dormancy. They require 2 to 3 months of warm, moist storage at 21° to 27° C (70° to 80° F) followed by a similar period of cold stratification at 1° to 5° C (34° to 41° F). Even with this treatment, germination of filled seeds may be 50 percent or lower (1,15). Seeds disseminated in nature or sowed in a nursery without special treatment germinate mostly during the second growing season (11). Fruits to be stored should be kept dry and cold, but no data are available on long-term storage (5).

Soils and Topography ( Anglèis )

fornì da Silvics of North America
Soils over the range of Carolina silverbell are mostly Ultisols but include sandy Entisols in the Southeast, Inceptisols in the mountains, and Mollisols in southern Illinois (32). The species prefers rich, moist, well-drained, loamy soil that is slightly acid in reaction (pH 5.0 to 6.0). It can tolerate soils more acid than that and may do well in soils with a pH up to 7.0 (11,23).

Carolina silverbell grows mostly along streams, river bluffs, and ravine slopes in the Piedmont and other lowlands and along streams, in coves, and on moist lower slopes in the mountains (4,8,10,24, 28,30). It is significant in frequency at elevations between 1370 and 1680 in (4,500 and 5,500 ft) and locally abundant at elevations between 460 and 1370 in (1,500 and 4,500 ft) in the mountains (10,25).

Special Uses ( Anglèis )

fornì da Silvics of North America
The wood of Carolina silverbell has many fine properties which make it very desirable for veneer, cabinet work, carving, and turning. It is a favorite wood of craftsmen who make woodenware for the tourist trade. The wood is soft with white or creamy sapwood and light cherry-colored heartwood streaked with white. Wood from larger trees has been sold as cherry or birch and the wood is acceptable for pulping along with other hardwood species. In the tourist trade it is sold under such names as bellwood, tisswood, and boxelder (14,17,18,26).

Squirrels use Carolina silverbell seeds for food and the trees for dens. The heavy flower crops in spring are very attractive to bees, and eastern Tennessee beekeepers speak highly of the species as a honey plant (12,22,33).

Carolina silverbell is best known for its ornamental qualities. Its heavy crop of white, bell-shaped flowers in the spring and its small to medium growth habit make it a favorite for small gardens, lawns, patios, and tubs. It was first cultivated in 1756 and since has been successfully cultivated in the Eastern United States, California, and western and central Europe (23,30). It transplants well as balled and burlapped or container-grown stock (11). Its best ornamental uses include border plantings in combination with low-growing plants such as azaleas, at corners of buildings and against a background of large evergreens. Its blooms can best be seen from below, so the tree needs to be conveniently accessible. Sprays of the flowers go well with cut-flower arrangements (2,16,19,34). The large form from the mountains should not be used in small gardens but can be used with delightful results for street plantings, although it is not quite as hardy as the smaller form. Some trees have predominantly pink flowers, but a shady site may be required to produce this trait (11,20,34).

Vegetative Reproduction ( Anglèis )

fornì da Silvics of North America
Carolina silver bell can easily be propagated by root and greenwood cuttings and by air-layering. Rooting hormones are not necessary for success but may enhance rooting at certain times of the year. For best success, cuttings should be taken after elongation of new growth but before hardening beings. Roots should not be disturbed until the end of the second season. Micropropagation techniques are being developed (1,3,11,17).

Earl R. Sluder

Carolina silverbell (Halesia carolina) is common and reaches its greatest size in the southern Appalachian Mountains where it is called mountain silverbell. This attractive shrub or small tree, also called snowdrop-tree or opossum-wood, grows in moist soils along streams in the understory of hardwood forests. It has a moderate growth rate and lives about 100 years. The wood is soft and close-grained and a favorite wood for crafts. The white bell-shaped flowers and small size make it a desirable tree for landscaping. The seeds are eaten by squirrels and the flowers provide honey for bees.

Halesia carolina oder der Schneeglöckchenbaum, Maiglöckchenbaum, ist ein Baum in der Familie der Storaxbaumgewächse aus den südöstlichen bis östlichen USA.

Beschreibung

Halesia carolina wächst als laubabwerfender Baum bis über 25 Meter hoch. Der Stammdurchmesser erreicht bis zu 90 Zentimeter.[1] Die gräuliche Borke ist rissig bis furchig.

Die wechselständigen, einfachen Laubblätter sind gestielt. Der Blattstiel ist bis 3 Zentimeter lang. Die 9–20 Zentimeter langen, dünnledrigen Blätter[1] sind eiförmig bis verkehrt-eiförmig oder elliptisch, spitz bis zugespitzt und meist feingesägt. Sie sind unterseits weiß-gräulich behaart und verkahlend, oberseits sind sie fast kahl. Die Nebenblätter fehlen. Die Herbstfärbung ist gelb.

Die hängenden Blüten erscheinen in achselständigen Büscheln oder kurzen Trauben mit wenigen Blüten oder selten einzeln. Die zwittrigen und gestielten, vierzähligen Blüten mit doppelter Blütenhülle sind weiß. Die 2,5–5 Zentimeter langen[1] Blütenstiele mit oben einem „Gelenk“[2] und der 5–6 Millimeter lange Blütenbecher sind mehr oder weniger behaart.[3] Die vier dreieckigen Kelchblätter sind nur sehr klein. Die vier Kronblätter sind etwa 1,5–2,5 Zentimeter lang und glockenförmig verwachsen mit abgerundeten Lappen. Die Kronröhre ist in der Länge recht variabel, von kurz bis lang. Es sind bis zu 16 kurze, an der Basis verwachsene Staubblätter vorhanden. Der mehrkammerige Fruchtknoten ist unterständig mit schlankem, kahlem Griffel und kleiner, schwach gelappter Narbe.

Es werden meist ein- bis viersamige, geschnäbelten Nüsschen (Scheinfrucht, Flügelfrucht) im beständigen und vierflügeligen Blütenbecher mit Kelchresten an der Spitze gebildet. Die rippigen, schmal verkehrt-eiförmigen Nüsschen sind ohne Flügel bis 2 Zentimeter lang, mit Flügeln bis 4–5 Zentimeter. Die verkehrt-eiförmigen und hängenden Früchte stehen noch lange an der Pflanze (Wintersteher).[1]

Die Chromosomenzahl beträgt 2n = 24.

Verwendung

Die jungen Früchte werden als Gemüse genutzt.[4]

Das relativ weiche und mittelschwere Holz wird für einige Anwendungen genutzt.

Halesia carolina ( Anglèis )

fornì da wikipedia EN

Halesia carolina, commonly called Carolina silverbell or little silverbell, is a species of flowering plant in the family Styracaceae, native to the southeastern United States.

Description

It is a vigorous, fast-growing deciduous shrub or tree growing to 8 m (26 ft) tall by 10 m (33 ft) broad, bearing masses of pendent, bell-shaped white flowers which appear in spring before the leaves. The flowers are followed by green, four-winged fruit. The leaves turn yellow in autumn.[3][4]

Range

The range of little silverbells is very restricted. It is principally in the panhandle of Florida, with isolated smaller outlier populations in South Carolina, Georgia, Alabama, Mississippi. In the cited reference, this species is referred to as Halesia parviflora.[5] The "champion" Halesia carolina on the 2015 American Forests' National Register of Champion Trees is quite removed from its natural range, being situated in Roxbury, New Hampshire.[6]

Taxonomy

There is a great deal of confusion in the four-winged American silverbells. Four principal species names have been used: H. carolina, H. parviflora, H. monticola, and H. tetraptera. The taxon being described here is the one that has also been described as H. parviflora.[7] Some botanists have discarded the name H. carolina because the original material is viewed as ambiguous; others maintain that the original material is this species, so carolina is here being used instead of parviflora, since H. carolina L. has clear precedence.[8]

Cultivation

In cultivation in the United Kingdom, H. carolina Vestita Group has gained the Royal Horticultural Society's Award of Garden Merit.[9][10] It requires an acid or neutral soil, in a partially shaded position.

Vista de la planta

Descripción

Es un vigorosa arbusto o árbol, de rápido crecimiento caducifolio que alcanza un tamaño de 8 m de alto por 10 m de ancho, formando grandes masas. Las flores pendientes en forma de campana, blancas que aparecen en primavera antes que las hojas. Las flores son seguidas por la fruta verde, con cuatro alas en forma de estrella que tiene un sabor un poco similar al de los guisantes. Las hojas se vuelven amarillas en otoño.[1][2]

Distribución y hábitat

El hábitat de Halesia carolina es muy restringido. Se encuentra principalmente en la península de Florida, con pequeñas poblaciones aisladas atípicas en Carolina del Sur, Georgia, Alabama, Misisipi. En la referencia citada, esta especie se conoce como Halesia parviflora.[3]

Cultivo

En el cultivo en el Reino Unido, H. carolina ha ganado el Premio al Mérito Garden de la Royal Horticultural Society.[4]

Taxonomía

Halesia carolina fue descrita por Carlos Linneo y publicado en Systema Naturae, Editio Decima 2: 1044, 1369. 1759.[5]

Existe una gran confusión en el tratamiento de esta especie. Cuatro nombres de especies principales se han utilizado: H. carolina , H. parviflora , H. monticola y H. tetraptera. El taxón que se describe aquí, también se ha descrito como H. parviflora.[6]​ Algunos botánicos han descartado el nombre de H. carolina porque el material original es visto como ambiguo, mientras que otros sostienen que el material original es esta especie, por lo que carolina se está utilizando aquí en lugar de parviflora, ya que H. carolina L. tiene clara prioridad.[7]

Snøklokketre ( norvegèis )

fornì da wikipedia NO

Snøklokketre (Halesia carolina) er en løvfellende busk eller lite tre i styraksfamilien som er utbredt i sørøstlige USA.

Beskrivelse

Det blir opptil 24 m høyt i de sørlige Appalachene, men er som regel lavere. Krona er bredt kjegleformet med vidt utsperrede nedre greiner. Barken er lysegrå. Bladene sitter spredt og er ovalt avlange, spisse, fint sagtannede, 8,7–22,5 cm lange og 3,8–11,4 cm brede. Nervene stikker ikke opp over bladflaten på oversiden, og undersiden er hårete. Blomstene er hvite, klokkeformede og henger 2–6 sammen. De har 4 begerblad, 4 kronblad og 12–16 pollenbærere. Blomstene ligner mer på krokus enn på snøklokker. Frukten er brun med 4 vinger.

Økologi og utbredelse

Snøklokketre vokser på fuktig, ofte litt sur og sandholdig jord opptil 1600 moh. I åslandet øst for Appalachene vokser den sammen med tulipantre, kvitask, rødlønn, kviteik, amerikakristtorn, amerikajudastre og storbladmagnolia. Sør i utbredelsesområdet finnes den sammen med amerikabøk, oksemagnolia, amerikakristtorn, ulike eikearter, floridalønn, virginiahumlebøk og amerikajudastre. I Great Smoky Mountains forekommer den sammen med canadahemlokk, gul hestekastanje, amerikasølvlind, sukkerlønn og gulbjørk, og i Blue Ridge Mountains er den funnet sammen med rødeik, sukkerbjørk, tulipantre, blomsterkornell og Magnolia fraseri.

Arten er hovedsakelig utbredt i åser og fjell i Nord-Carolina, Sør-Carolina, østlige Tennessee, Georgia og Alabama. Mer spredte forekomster finnes på den sørøstlige kystsletta og i vestlige Virginia, Vest-Virginia, sørlige Ohio, sørlige Indiana, sørlige Illinois, Kentucky, Tennessee, sentrale Arkansas og sørøstlige Oklahoma.

Systematikk

En buskaktig form med små blomster på kystsletta skilles ofte ut som en egen art, Halesia parviflora. Den høye formen i de sørlige Appalachene blir en sjelden gang skilt ut som en egen art, Halesia monticola.

Linnés beskrivelse av Halesia carolina var basert på materiale fra formen som tradisjonelt er blitt kalt Halesia parviflora. Hvis den skal ha status som egen art, må den overta navnet Halesia carolina, og formen fra høyereliggende områder må i stedet kalles Halesia tetraptera.
