Download or read book A Localized Morphometric Study of Panicum Virgatum and Sister Taxa Poaceae Panicoideae Paniceae written by Sarah Elizabeth Youngstrom and published by . This book was released on 2009* with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Morphological distinctions were evaluated between taxa of Panicum section Virgata Nees as recognized by Hitchcock and Chase (1951) and Freckmann and Lelong (2002b): P. virgatum var. virgatum, P. virgatum var. cubense, P. amarum subsp. amarum, and P. amarum subsp. amarulum, using morphometrics and greenhouse experiments on material from the southeastern United States, a region with the most extreme overlap in distribution. 31 characters for 104 specimens were subject to univariate, bivariate, and multivariate analyses. Spikelet bivariate graphs showed two groups with large (C) and small (A+B) spikelets. When habitat, distribution, and phenology was superposed on these graphs, non-exclusive trends polarized the small spikelet group into two groups (A) and (B). Morphogroups A, B, and C did not overlap on PCA graphs, but were not separated by gaps. Results show two morphogroups present: A+B (P. virgatum var. virgatum, var. cubense, P. amarum subsp. amarulum) and C (P. amarum subsp. amarum).

This book was released on 2012-12-06 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook, consisting of six volumes, covers over 9000 taxa of succulents (excluding cacti), which have the ability to store water in their stems, leaves, or underground organs. In addition to the volumes on Monocotyledons and Dicotyledons, separate volumes are devoted to those families with predominantly succulent members, which show an especially great diversity, namely Aizoaceae, Asclepiadaceae and Crassulaceae. Following an alphabetical listing of families, genera and species, detailed descriptions are given, including the taxonomy with synonyms, data on the distribution and ecology, references, and keys to genera, species or subspecies. Over 2000 superb colour photographs complete this inventory of succulent plants.

Available in PDF, EPUB and Kindle. Book excerpt: A quorum of scientists offer reviews and results to celebrate the 150th anniversary of 'On The Various Contrivances By Which British And Foreign Orchids Are Fertilised By Insects, And On The Good Effects Of Intercrossing' (1862). Authors of the first ten chapters follow research on the pollination and breeding systems of the same orchid lineages that interested Darwin, including temperate and tropical species. Authors on the last two chapters provide information on the floral attractants and flowering systems of orchids using protocols and technologies unavailable during Darwin's lifetime.

Download or read book Plant Immunity written by John M. McDowell and published by Humana Press. This book was released on 2011-03-02 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A great deal of effort is being invested in understanding the molecular mechanisms through which plants interact with pathogenic microbes. In Plant Immunity: Methods and Protocols, expert researchers in the field describe emerging technologies that can be applied to the most significant outstanding questions faced by scientists studying immunity in plants. The technologies in this detailed volume include methods for examining protein localization, protein complex purification, protein-protein interactions, transient and inducible gene expression, chromatin immunoprecipitation, microaspiration, laser microdissection, purification of fungal haustoria, and genetic manipulation of bacterial and oomycete pathogens. These techniques are applicable to a wide range of topics, including molecular functionality of NB-LRR proteins and other immune signaling components, and functional characterization of effector proteins and other pathogen components that sabotage host immunity. Written in the highly successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls.
Download or read book Steyermark s Flora of Missouri written by Julian Alfred Steyermark and published by Missouri Botanical Garden Press. This book was released on 1999 with total page 1016 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Flora of Missouri project, directed by Garden Curator, Dr. George Yatskievych, is an ongoing effort to update and compile information on the state's flora. It began in 1987 as a joint effort of the Missouri Botanical Garden and the Missouri Department of Conservation. One of its main goals is a three-volume revision of former Missouri Botanical Garden curator Julian A. Steyermark's 'Flora of Missouri', first published in 1963. Missouri's ever changing plant diversity, the shifting distributions of its plant species, and the many new records of plants in the state have necessitated an expansion of Steyermark's original publication into three volumes."--
Download or read book Flowering Plants Flowering Rush to Rushes written by Robert H. Mohlenbrock and published by SIU Press. This book was released on 1970 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Robert H. Mohlenbrock provides a definitive account of the pokeweed, four-o'clock, carpetweed, cactus, purslane, goosefoot, pigweed, and pink families in Illinois. Flowering Plants: Pokeweeds, Four-o'clocks, Carpetweeds, Cacti, Purslanes, Goosefoots, Pigweeds, and Pinks is the fifteenth volume of the Illustrated Flora of Illinois series and the ninth devoted to dicots, or plants that have two seed-leaves, or cotyledons, upon germination. Each of the 141 plants is beautifully illustrated by Paul W. Nelson. Nelson shows the full habitat of the plant and close-ups of various vegetative and reproductive structures that are crucial for the identification of individual species. Each illustration includes detailed drawings of the flowers, fruits, and seeds of the plant covered. Mohlenbrock provides a complete description of each species as well as a discussion of the nomenclature and habitats, and his fifty-three years of experience enable him to present little-known diagnostic features for many species. Range maps show the county distribution of each species in Illinois. Mohlenbrock includes a statement giving the overall range of each species in the United States as well as a detailed key for the identification of the species. Flowering Plants contains many plants whose obscure flower parts make them exceedingly difficult to identify. The close-up illustrations of these parts will aid the user of the book immensely in identification of the species. Included are several species previously unknown in Illinois. New illustrations, which include detailed drawings of the flowers, fruits, and seeds are presented for each species covered in this book. Mohlenbrock's fifty-three years of experience enable him to present little-known diagnostic features for many species.
