O. Box 9514, 2300 RA Leiden, THE NETHERLANDS (Received on March 5, 2009) In 1851, Carl Lodewijk von Blume, who studied extensively the specimens collected in Japan by Siebold, Bürger, their successors, and their Japanese correspondents, described a great number of new species and varieties of Quercus and other genera of Fagaceae. His treatment, especially of Quercus, influenced later workers on the family, and also studies of the flora and vegetation of Japan. To stabilize the taxonomy of the family, lectotypes for taxa described by Blume are herein designated for Quercus (13 species and 13 varieties), Lithocarpus (1 and 2), Castanea (1 and 10), and Fagus (1 and 2). Key words: Fagaceae, Japanese flora, lectotypification, Siebold collections. Carl Lodewijk von Blume (Karl Ludwig not designate lectotypes. The type concept was von Blume) studied extensively the specimens not as well developed at those times as it is collected in Japan by Siebold, Bürger, their now. successors, and their Japanese correspondents. Siebold, Bürger, their successors, and Blume (1851) described a great number of their Japanese correspondents gathered the new species and varieties of Quercus and specimens from various sources. The majority other genera of Fagaceae, and his treatment, of the specimens appear to be from trees especially of Quercus, influenced later workers in spontaneous situations, but some were on the family and also studies of the flora and collected from cultivated trees in various vegetations of Japan. gardens and nurseries. Although several Japanese botanists During preparation of manuscripts on studied the specimens used by Blume, they Fagaceae for recent publications on the did not designate any lectotypes.

  • The Effects of Chemical Components and Particle Size on the Mechanical
    Journal of Wood Science (2018) 64:246–255 https://doi.org/10.1007/s10086-018-1695-y ORIGINAL ARTICLE The effects of chemical components and particle size on the mechanical properties of binderless boards made from oak (Quercus spp.) logs degraded by shiitake fungi (Lentinula edodes) Florence Hiu Yan Lui1 · Yoko Kurokochi1 · Hiroe Narita1 · Yukie Saito1 · Masatoshi Sato1 Received: 27 September 2017 / Accepted: 22 December 2017 / Published online: 15 February 2018 © The Japan Wood Research Society 2018 Abstract Binderless boards are composite boards that rely on self-bonding mechanisms for inter-fibre bonding. Quercus acutissima and Quercus serrata logs degraded by Lentinula edodes (shiitake fungi) were used in this study to investigate whether physical and chemical changes induced by shiitake fungi can enhance board mechanical properties. Binderless boards were manufactured with 0.8 g/cm3 target density, 220 °C pressing temperature, 5 MPa pressure, and pressing duration of 10 min. Boards made from logs degraded for ≥ 26 months were stronger than control boards and met modulus of rupture (MOR) and internal bonding (IB) requirements for fibreboards. Chemical composition and particle size distribution of the wood powder used to make the boards were determined to elucidate the drivers of board mechanical properties. The proportion of small particles (< 150 µm) showed a strong positive correlation with MOR for both species and hot water extractives showed a strong positive correlation with IB for Q. acutissima boards. Introduction of shiitake fungi pre-treatment to the production process may enhance the mechanical strength of binderless boards.

  • Jeannine Cavender-Bares 2 and Annette Pahlich
    American Journal of Botany 96(9): 1690–1702. 2009. M OLECULAR, MORPHOLOGICAL, AND ECOLOGICAL NICHE DIFFERENTIATION OF SYMPATRIC SISTER OAK SPECIES, QUERCUS VIRGINIANA AND Q. GEMINATA (FAGACEAE) 1 Jeannine Cavender-Bares 2 and Annette Pahlich Department of Ecology, Evolution, and Behavior; University of Minnesota, St. Paul, Minnesota 55108 USA The genus Quercus (the oaks) is notorious for interspecifi c hybrization, generating questions about the mechanisms that permit coexistence of closely related species. Two sister oak species, Quercus virginiana and Q. geminata , occur in sympatry in Florida and throughout the southeastern United States. In 11 sites from northern and southeastern regions of Florida, we used a leaf-based morphological index to identify individuals to species. Eleven nuclear microsatellite markers signifi cantly differentiated between the species with a high correspondence between molecular and morphological typing of specimens. Nevertheless, Bayesian clus- tering analysis indicates interspecifi c gene fl ow, and six of 109 individuals had mixed ancestry. The identity of several individuals also was mismatched using molecular markers and morphological characters. In a common environment, the two species per- formed differently in terms of photosynthetic performance and growth, corresponding to their divergent ecological niches with respect to soil moisture and other edaphic properties. Our data support earlier hypotheses that divergence in fl owering time causes assortative mating, allowing these ecologically distinct sister species to occur in sympatry. Limited gene fl ow that permits ecologi- cal differentiation helps to explain the overdispersion of oak species in local communities. Key words: Fagaceae; Florida; fl owering time; habitat differentiation; morphological variation; nuclear microsatellites; Quercus geminata ; Q.

These species extend over diverse environmental conditions and are thus interesting models for studies of plant adaptation and speciation. The genomic toolbox is an important asset for exploring the functional variation associated with natural selection. Results: The assembly of previously available and newly developed long and short sequence reads for two sympatric oak species, Quercus robur and Quercus petraea, generated a comprehensive catalog of transcripts for oak. The functional annotation of 91 k contigs demonstrated the presence of a large proportion of plant genes in this unigene set. Comparisons with SwissProt accessions and five plant gene models revealed orthologous relationships, making it possible to decipher the evolution of the oak genome. In particular, it was possible to align 9.5 thousand oak coding sequences with the equivalent sequences on peach chromosomes.

Written in the format of papers appearing in the Proceedings of the Oklahoma Academy of Science, Chapter I describes the results of a floristic survey of three tracts of the Ozark Plateau National Wildlife Refuge located in the Boston Mountains ecoregion in Adair County, Oklahoma. Written in more or less traditional thesis format, Chapter II offers a taxonomic treatment of the genus Quercus in Oklahoma which is to be incorporated in the forthcoming Flora of Oklahoma. The taxonomic keys for the sections and species of the genus have already been inserted in Keys and Descriptions of the Vascular Plants of Oklahoma. Partial financial support for my floristic work on the Ozark Plateau National Wildlife Refuge was provided by the U.S. Fish and Wildlife Service.

The antioxidant capability and phenolic contents of ethanol extracts (free phenolics) and ethyl acetate extracts (bound phenolics) of three Quercus species were estimated in this work. The antioxidant activities were examined by 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) free radical, reducing power and -carotene bleaching methods. HPLC was employed to detect major phenolic acids. The leaf extract of Q. salicina contained maximum total phenolics while the highest total flavonoid content was found in the leaf extract of Q. serrata. The antioxidant activities varied among three species.

In total, 2152 samples from 18 naturally regenerated populations and 28 planted populations in Japan and 13 populations from the northeastern part of Eurasia, near Japan, were analyzed using six maternally inherited chloroplast (cpDNA) simple sequence repeat (SSR) markers.
