Abstract:

Lukiessani Israel Schefflerin tekstejä huomasin meitä molempia kiinnostavan ihmisen kognitiivinen järjestelmä ja kasvatus. Israel Scheffler on koulutusfilosofian tutkimuskeskuksen johtaja Harvardin yliopistossa. Hänen uransa alkoi Harvardissa jo vuonna 1952. Scheffleriä pidetään kasvatusfilosofina, joka on ollut pitkän uransa aikana kiinnostunut monista asioista, esimerkiksi kielifilosofiasta, tieteenfilosofiasta ja kasvatuksen kysymyksistä. Schefflerin ajattelua on Suomessa tutkittu varsin vähän, vaikka häntä pidetään englanninkielisellä alueella hyvin merkittävänä kasvatusfilosofiana.

Abstract:

Israel Scheffleriä voidaan joiltain osin tulkita kantilaisena pragmatistina, kuten Timo Tolska häntä tulkitsee Aikuiskasvatus-lehdessä (3/2003) julkaistussa artikkelissaan ”Kognitiivinen järjestelmä ja sen yhteydet kasvatukseen Israel Schefflerin filosofiassa”. Toinen mahdollinen, mielestäni perustellumpi Scheffler-tulkinta korostaa Scheffleriä yhtenä merkittävimmistä filosofeista, jotka ovat argumentoineet uuden, käsitejärjestelmiimme ennen sisältymättömän tiedon mahdollisuuden puolesta. Tämän tulkinnan pohjalta voidaan päätyä näkemykseen Scheffleristä ontologisena realistina. Sivulla 303: Timo Tolska vastaa / Timo Tolska

Abstract:

The wood anatomy of 22 of the 26 species of Schefflera occurring in New Caledonia was studied. Only two features (the presence of scalariform perforation plates and scanty paratracheal axial parenchyma) appear to be constant throughout the species examined. The pattern of wood structure diversity was analyzed using PCA; the results generally agree with the current recognition of four groups of species among New Caledonian Schefflera based on macromorphology. Three of these groups (Dizygotheca, “Canacoschefflera” and “Gabriellae”) represent natural assemblages closely related to one another. The fourth group (Schefflera sect. Schefflera) is isolated from the others, as indicated by its very large rays and abundant septate fibres. The occurrence of crystals in chambered cells of axial parenchyma was observed for the first time in Araliaceae. The wood structure of Schefflera plerandroides, previously placed in the segregate genus Octotheca, shows no essential differences from that of the other members of the Dizygotheca group, supporting the hypothesis that polymerous flowers have evolved independently at least twice within the Schefflera alliance.

Abstract:

Novelty Araliaceae potted plants were created by a wide variety of interspecific and intergeneric graft combinations. Twenty-four species of 10 genera were tested, of which 20 species of eight genera resulted in 85 graft combinations that grew. Intergeneric graft combinations with Schefflera arboricola included eight species in five other genera. Intergeneric graft combinations with x Fatshedera lizei included 11 species in five other genera. Schefflera arboricola scions grew more vigorously on Nothopanax and Polyscias rootstocks than on Schefflera root-stocks. The highest intergeneric graft compatibility scores for each genera included combinations with Schefflera. Plant propagation instructors may find these results useful in designing grafting exercises.

Abstract:

Исследование структуры синфлоресценций шести азиатских видов рода Schefflera s. l. выявило их высокое разнообразие в данной группе. Синфлоресценции изученных видов относятся к двум типам: метелка из элементарных соцветий и двойная кисть из элементарных соцветий. Элементарным соцветием в первом случае является открытый зонтик либо кисть, во втором — открытый зонтик (у некоторых видов — головка). Данные типы синфлоресценции отличаются друг от друга наличием терминальных элементарных соцветий на главной и боковых осях, осностью растения и ритмикой распускания цветков. Обоснована гипотеза о детерминированном характере развития синфлоресценций у видов рода Schefflera с двойной кистью. Показано, что для азиатских видов рода Schefflera с метелками из зонтиков характерно наличие в синфлоресценции одиночных цветков, расположенных под некоторыми из зонтиков, что делает строение этих элементарных соцветий промежуточным между зонтиком и кистью.

Abstract:

Following recent studies showing that Asian Schefflera should be treated under the separate genus Heptapleurum, the names for the Thai species belonging to this genus are listed. Two new combinations are proposed for S. bengalensis and S. poomae. For two species of Schefflera recognized, S. pueckleri and S. simulans, different epithets must be used under Heptapleurum, namely H. calyptratum and H. affine.

Abstract:

In late winter and spring of 2006 and 2008, leaf spots with yellow halos were observed on dwarf schefflera (Schefflera arboricola cvs. Gold Capella, Trinette, and Green Gold) that were grown as potted plants in two commercial ornamental greenhouses in Adana and Mersin, Turkey. Average disease incidence was assessed as 10% during the term of the study. Isolations were made from leaf spots symptoms on King's medium B. Bacteria consistently isolated from diseased tissues formed green fluorescent colonies on the medium. Ten representative bacterial strains were examined and found to be gram negative, rod shaped, and aerobic, levan, pectolytic, and arginine dihydrolase negative, and oxidase positive. They all induced a hypersensitive response in tobacco (Nicotiana tabacum cv. Samsun). All strains were identified as Pseudomonas cichorii with similarity indices of 79 to 99% based on fatty acid methyl ester (FAME) profiles determined by Sherlock Microbial Identification System software (TSBA 6 v. 6.00; Microbial ID, Newark, DE). Pathogenicity of the strains was confirmed on five dwarf schefflera plants by leaf tissue infiltration with bacterial suspensions (107 CFU ml–1) in sterile distilled water. P. cichorii NCPPB 3802 and sterile water were used as positive and negative controls, respectively. The same symptoms as those observed in the commercial greenhouses were observed on dwarf schefflera leaves within 12 to 15 days after inoculation. The bacteria were reisolated from the inoculated plants and identified as the same as the original strain by conventional tests and FAME analysis. Negative control plants remained disease free. Occurrence of bacterial leaf spot caused by P. cichorii on vegetable crops in Turkey (1,3) and dwarf schefflera in other countries (2) has been reported previously, but to our knowledge, this is the first report of the observation of P. cichorii on dwarf schefflera in Turkey.

Abstract:

Two new species of the largely Brazilian Didymopanax clade of Schefflera (Araliaceae) are here described, illustrated, and compared to similar taxa. Both are from poorly sampled areas in the Brazilian Amazon Basin. Schefflera prancei is known only from the Serra do Divisor National Park, at the border between Brazil and Peru. It differs from the similar S. confusa by its leaflets with narrowly elliptic to oblanceolate blades, with an acuminate to cuspidate apex, and the light brown to grayish sericeous indument on the abaxial blade surface. The second new species, Schefflera pubicarpa, is found in central Amazonian forests, and differs from similar species of the clade by a combination of characters, including a large-tree habit, leaves with 8 to 10 leaflets, inflorescences with ascending secondary branches and lacking tertiary branches, flowers with trichomes along the styles, and pubescent fruits. While this species appears to have a restricted distribution in Brazil, a westward extension reaching into Peru, Colombia, and Ecuador may be likely as new collections from intermediate areas become available.

Abstract:

Fifteen-cm (6 in) pots containing a peat-lite medium and no plants were leached with varying amounts of water for soluble salts (SS) analysis. Volume of water applied to pots within ranges tested was not an important factor when determining leachate soluble salts. Dieffenbachia maculata (Lodd) G. Don ‘Compacta’ and Schefflera arboricola H. Ayata (Dwarf schefflera) were fertilized with different sources and rates. Good quality Dieffenbachia were grown with a range of 2750 to 7700 kg N/ha/year (2500 to 7000 lbs/A/yr) with SS of leachate from 341 to 9750 micromhos/cm and 128 to 1243 from a 2:1 by volume method. Dwarf schefflera grew best with a range of 1100 to 6050 kg N/ha/year (1000 to 5500 lbs/A/yr) and SS of leachate from 1384 to 11796, and 2:1 extract from 159 to 1512. Level of conductivity varied considerably within treatments and was not a good indicator of desired soil fertility. Further tests showed that the pour-through method was best when percent of soil moisture varied between 33 and 100%.

Abstract:

Perforated ray cells (PRCs) are recorded here for the first time in the roots and branches of Schefflera vinosa, Caryocar brasiliense, Acosmium subelegans, Byrsonima basiloba, B. coccolobifolia, B. verbascifolia and Alibertia concolor which occur in Pratâniaʼs cerrado (SP, Brazil). PRCs are larger than normal ray cells, occurring isolated or in groups of two or more in the same ray, and are present predominantly in the uniseriate portion of multiseriate rays in all species studied. In the roots and branches, the types of perforation plates (PP) of the PRCs are similar to those of the vessel elements (VE) in most species, with the exception of the branches of Schefflera vinosa and the branches and roots of Caryocar brasiliense. The diameter of the PRC plates was greater in the roots than in the branches, but the differences were only statistically significant in Schefflera vinosa, Byrsonima basiloba and B. verbascifolia. In a general way the PRC plates were greater in diameter than the VE plates in both roots and branches of most species.

Abstract:

Exposure to 0.1, 1.0, or 10 μL·L−1 ethylene for 4 days at 21 °C reduced the display life of 17 commonly traded potted foliage plant genotypes (Aglaonema ‘Mary Ann’, Anthurium scherzerianum ‘Red Hot’ and ‘White Gemini’, Aphelandra squarrosa ‘Dania’, Chlorophytum comosum ‘Hawaiian’, Codiaeum variegatum pictum ‘Petra’, Dieffenbachia maculata ‘Carina’, Dracaena marginata ‘Bicolor’ and ‘Magenta’, Euphorbia milii ‘Gaia’, Euphorbia splendens ‘Short and Sweet’, Ficus benjamina, Polyscias fruticosa ‘Castor’, Radermachera sinica ‘China Doll’, Schefflera elegantissima ‘Gemini’, Schefflera arboricola ‘Gold Capella’, Spathiphyllum ‘Ty's Pride’). Ethylene treatment hastened leaf and bract abscission or senescence. The responsiveness of plants to ethylene varied considerably; six genotypes were sensitive to 0.1 μL·L−1 ethylene, whereas three genotypes required exposure to 10 μL·L−1 ethylene to trigger visible injury. Four genotypes (Asplenium nidus, Chamaedorea elegans ‘Neathe Bella’, Hedera helix ‘Chicago’, Syngonium podophyllum ‘White Butterfly’) included in our study were insensitive to ethylene. Treating Aglaonema ‘Mary Ann’, Polyscias fruticosa ‘Castor’, and Schefflera arboricola ‘Gold Capella’ plants with 0.9 μL·L−1 1-methylcyclopropene (1-MCP, provided as EthylBloc™), a gaseous ethylene-binding inhibitor, for 4 to 5 h at 21 °C reduced the deleterious effects of ethylene. The release of 1-MCP from two sachets containing EthylBloc™ into a single shipping box also protected Aphelandra squarrosa ‘Dania’, Euphorbia milii ‘Gaia’, Polyscias fruticosa ‘Elegans’, and Schefflera arboricola ‘Gold Capella’ plants from ethylene injury after simulated transport. Our data reveal the genetic variation in ethylene sensitivity among potted foliage plants and highlight genotypes that benefit from 1-MCP treatment.

Abstract:

Xanthomonas campestris pv. hederae (synonym X. hortorum pv. hederae) strains (59 total) were collected from plants in the araliaceae family. Strains were isolated from Hedera helix, Schefflera arboricola, Brassaia actinophylla, and Polyscias spp. from Florida, California, Hawaii, and New Zealand. All strains produced yellow mucoid growth; hydrolyzed esculin, starch, casein and gelatin; were pectolytic; produced urease; and grew on minimal media containing asparagine. All bacterial strains were pathogenic on H. helix (English ivy), B. actinophylla (dwarf schefflera), and Polyscias fruticosa (ming aralia). No differences in symptomatology were detected among strains; however, severity of symptoms usually was greatest on the host of origin. In planta growth rates of representative strains isolated from H. helix, B. actinophylla, and Polyscias spp. also were compared among these three hosts. In all cases, populations grew more rapidly when strains were inoculated to their original host species. All 59 bacterial strains were compared by 95-carbon source GN microplate, fatty acid methyl ester (FAME), and restriction fragment-length polymorphisms (RFLP), with the pulse-field gel electrophoresis method, analyses. All three analyses grouped strains into two distinct groups that correlated with the host of origin. Using metabolic profiles, 75% of the H. helix strains were separated from strains isolated from Brassaia and Schefflera and 95% of the Polyscias strains. FAME analysis separated strains into two distinct groups, with 96% of the H. helix strains placed in one group. RFLP analysis placed all of the H. helix and Schefflera strains in one group, as well as 33% of the Brassaia strains, whereas the other group contained all of the Polyscias strains and the remainder of the Brassaia strains. It is apparent that the pathovar hederae is made up of heterogeneous populations that can be separated by biochemical, pathological, genetic, and physiological analyses into two groups that are closely associated with the host of origin.

Abstract:

Schefflera umbellifera (Sond.) Baill. is an evergreen tree widely used as traditional medicine throughout its distributional range in southern Africa. Schefflera umbellifera is indigenous to Eswatini, Malawi, Mozambique, South Africa and Zimbabwe. This study was aimed at providing a critical review of medicinal uses, phytochemical and pharmacological properties of S. umbellifera. Documented information on medicinal uses, phytochemical and pharmacological properties of S. umbellifera was collected from several online sources such as Scopus, Google Scholar, PubMed, Francis and Taylor and Science Direct, and pre-electronic sources such as book chapters, books, journal articles and scientific publications obtained from the University library. This study revealed that the bark, leaf and root decoction or infusion of S. umbellifera are mainly used as diuretic, laxative, colic and protective charm, and traditional medicine for stomach ulcers, weaning infants, insanity, inflammation, rheumatism and malaria. Phytochemical compounds identified from the species include 3-hydroxy-20(29)-lupen-28-ol, 7-hydroxy-6-methoxycoumarin, betulin, ent-kaur-16-en-19-oic acid and oleanolic acid. Pharmacological research revealed that S. umbellifera extracts and compounds isolated from the species have antibacterial, anti-HIV, anti-inflammatory, antimalarial, antiprotozoal, larvicidal and cytotoxicity activities. Schefflera umbellifera should be subjected to detailed phytochemical, pharmacological and toxicological evaluations aimed at correlating its medicinal uses with its phytochemistry and pharmacological activities.

Abstract:

Molecular genetic analyses were used to reconstruct phylogenetic relationships and estimate divergence times for Raukaua species and their close relatives. A monophyletic group identified as the ‘greater Raukaua clade’ was circumscribed, with eight representative species; its basal divergence was estimated at c. 70 Mya, possibly after Zealandia had separated from Gondwana. Raukaua is paraphyletic because of the placement of Motherwellia, Cephalaralia, Cheirodendron and Schefflera s.s. The phylogeny supports a more narrowly circumscribed Raukaua that includes the New Zealand but not the South American or Tasmanian representatives. Ancestors of the monophyletic South American and Tasmanian Raukaua and the mainland Australian Motherwellia and Cephalaralia diverged at c. 66 Mya and their current disjunction may be vicariant, with overland dispersal between Australia and South America, possibly via Antarctica. Vicariance is also a likely mechanism for divergence at c. 57 Mya of the monophyletic Motherwellia, Cephalaralia and Tasmanian Raukaua. The common ancestor of New Zealand Raukaua¸ Cheirodendron and Schefflera s.s. is inferred to have existed c. 62 Mya in New Zealand, before the marine incursions during the Oligocene, implying that New Zealand Raukaua and Schefflera s.s. survived the inundation period or speciated outside New Zealand and subsequently colonised. Ancestors of Cheirodendron split from New Zealand Raukaua c. 43 Mya and dispersed over vast expanses of the south-western Pacific to Hawaii.

Abstract:

The leaf essential oils of Dendropanax capillaris, Oreopanax nubigenus and Schefflera rodrigueziana (Araliaceae) were isolated by hydrodistillation and analyzed by GC-MS. The leaf oil of Dendropanax capillaris was composed of only four compounds, β-pinene (25.3%), δ-3-carene (44.7%), daucene (17.1%), and dauca-5,8-diene (12.9%). Oreopanax nubigenus leaf oil was dominated by the sesquiterpene hydrocarbons germacrene D (70.1%) and β-caryophyllene (11.8%), while Schefflera rodrigueziana leaf oil was made up entirely of sesquiterpene hydrocarbons, mostly germacrene D (27.6%), β-cubebene (27.2%), β-caryophyllene (12.2%), α-cubebene (11.1%), and α-copaene (10.8%). Both O. nubigenus and S. rodrigueziana leaf oils showed notable in-vitro cytotoxicity on MDA-MB-231 cells, which may be attributable to the relatively high concentrations of germacrene D and β-caryophyllene in those oils.

Abstract:

The polyphyly of the pantropical genus Schefflera J. R. Forst. & G. Forst. (Araliaceae) is now well established, and consequently the genus has had to be restricted to its type (S. digitata J. R. Forst. & G. Forst.) and seven closely related Pacific Island species. Taxonomic transfers of the members of four other, unrelated clades have mostly been completed, including those from Africa and Madagascar, the Neotropics, and Oceania. Here we treat the final and largest group, from Asia, reinstating the genus Heptapleurum Gaertn. for the 317 species that belong to the Asian clade of Schefflera. This synopsis provides 256 new combinations for 246 species and 10 varieties, along with one replacement name, and types are designated for five generic and infrageneric names. With the completion of these transfers, Heptapleurum is now the largest genus in Araliaceae.

Abstract:

Five species of tropical trees, West Indian mahogany [Swietenia mahagoni (L.) Jacq.], Key lime [Citrus aurantiifolia (Christm.) Swingle], schefflera (Brassaia actinophylla Endl.), pink tabebuia [Tabebuia pallida (Lindl.) Miers], and pigeon plum (Coccoloba diversifolia Jacq.) were grown for 17 months in 50 cm (20 in) diameter galvanized steel containers (20 gal), with 2 potting media: a 4:1 (v:v) blend of sewage sludge compost: sifted incinerator ash; and a mix of 3:3:2:2:1 (v:v:v:v:v) cypress shavings: perlite: Canadian peat: muck (“Florida peat”): sand (commercial mix). Plants were irrigated with either tap water or secondary treated sewage effluent supplied by a low volume drip system. Schefflera grew faster in the commercial mix irrigated with tap water. The remaining 4 species grew equally as well in the sludge compost: ash medium irrigated with effluent, as they did in the commercial mix irrigated with tap water.
