While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image.

  • DDC) Stemming from the Adoption of the APG (Angiosperm Phylogeny Group) III Classification As the Basis for the DDC’S Treatment of Flowering Plants
    This PDF documents proposed changes throughout the Dewey Decimal Classification (DDC) stemming from the adoption of the APG (Angiosperm Phylogeny Group) III classification as the basis for the DDC’s treatment of flowering plants. We request comment from any interested party, to be sent to Rebecca Green ([email protected]) by 31 January 2016. Please include “Angiosperm review comments” in your subject line. -------------------------------------------------------------- Why is the DDC adopting a new basis for classifying angiosperms (flowering plants)? During the latter half of the 20th century, biological classification turned from establishing taxa predominantly on the basis of morphological similarities to establishing taxa predominantly on the basis of shared ancestry / shared derived characters, with biological taxonomies mirroring evolutionary relationships. Phylogenetic analysis typically underlies modern evolutionary classifications, but has resulted in the development of many competing classifications. Within the domain of flowering plants, different classification systems have been favored in different countries. The Angiosperm Phylogeny Group, a global consortium of botanists, has addressed this issue by developing a “consensus” classification that is monophyletic (i.e., its taxa include all but only the descendants of a common ancestor). Now in its third version, the APG III classification is considered relatively stable and useful for both research and practice (e.g., for organizing plants in herbaria). The development for flowering plants presented here is the culmination of DDC editorial work over a span of several years. An early version revised 583–584 to make the schedule compatible with the APG III classification, while trying to minimize relocations and using see references to establish the APG III logical hierarchy.

  • Plant Diversity in Burapha University, Sa Kaeo Campus
    doi:10.14457/MSU.res.2019.25 ICoFAB2019 Proceedings | 144 Plant Diversity in Burapha University, Sa Kaeo Campus Chakkrapong Rattamanee*, Sirichet Rattanachittawat and Paitoon Kaewhom Faculty of Agricultural Technology, Burapha University Sa Kaeo Campus, Sa Kaeo 27160, Thailand *Corresponding author’s e-mail: [email protected] Abstract: Plant diversity in Burapha University, Sa Kaeo campus was investigated from June 2016–June 2019. Field expedition and specimen collection was done and deposited at the herbarium of the Faculty of Agricultural Technology. 400 plant species from 271 genera 98 families were identified. Three species were pteridophytes, one species was gymnosperm, and 396 species were angiosperms. Flowering plants were categorized as Magnoliids 7 species in 7 genera 3 families, Monocots 106 species in 58 genera 22 families and Eudicots 283 species in 201 genera 69 families. Fabaceae has the greatest number of species among those flowering plant families. Keywords: Biodiversity, Conservation, Sa Kaeo, Species, Dipterocarp forest Introduction Deciduous dipterocarp forest or dried dipterocarp forest covered 80 percent of the forest area in northeastern Thailand spreads to central and eastern Thailand including Sa Kaeo province in which the elevation is lower than 1,000 meters above sea level, dry and shallow sandy soil. Plant species which are common in this kind of forest, are e.g. Buchanania lanzan, Dipterocarpus intricatus, D. tuberculatus, Shorea obtusa, S. siamensis, Terminalia alata, Gardenia saxatilis and Vietnamosasa pusilla [1]. More than 80 percent of the area of Burapha University, Sa Kaeo campus was still covered by the deciduous dipterocarp forest called ‘Khok Pa Pek’. This 2-square-kilometers forest locates at 13°44' N latitude and 102°17' E longitude in Watana Nakorn district, Sa Kaeo province.

  • 1 Taxonomy of Grain Legumes R.M
    1 Taxonomy of grain legumes R.M. Polhill and L.J.G. van der Maesen INTRODUCTION The taxonomy; of grain legumes is relatively uncomplicated compared to that of cereals, brassicas and some other i groups of plants because, in general, only limited gene pools have been available for selection and subsequent plant breeding. Then again, intergeneric legume hybrids are not known in nature and artificial crosses attempting to create them are seldom, if ever, successful [64]. Indeed, the genetic barriers between species and species groups are often substantial [86,87]. The classification' of interfertile species and infraspecific variants is inherently more difficult and the taxonomic situation in grain legumes is not exceptional. In some instances the available information would now seem to justify updating of the taxonomic framework. TRIBES Most grain legumes belong to two tribes, the Vicieae and the Phaseoleae. The Vicieae and many Phaseoleae have the unusual combination of hypogeal germination and a herba­ ceous habit. Hypogeal cotyledons with large food reserves are characteristic of forest plants and the twining pro­ pensity of Phaseoleae and the tendrils of Vicieae may represent residual traits of that ancestral association. 3 Grain Legume Crops The interchange between epigeal and hypogeal germination involves major reorganisations of seed structure, composi­ tion and behaviour such that many families are restricted to one system or the other [102], In legumes, both systems occur widely and, as shown in Vhaseolus for example, the interchange is under fairly simple genetic control [30]. The most advanced tribes have tended to become predomi­ nantly herbaceous and most are obligately epigeal with small hard seeds produced in large numbers, with long viability and staggered opportunistic germination.
