    Lincoln University Campus: a Guide to Some of the Shrubs Currently Growing There”

    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Lincoln University Research Archive “Lincoln University campus: a guide to some of the shrubs currently growing there” Roy Edwards Department of Agricultural Science Lincoln University May 2009 The purpose of this book is to illustrate some of the range of shrubs currently grown on the Lincoln University campus. There are also a few trees that were not covered in the 1st book. This should be read in conjunction with its companion - “Lincoln University campus - a guide to some of the trees currently growing there” (April 2008). This also is a first draft and hopefully there will be further editions that will add species to address some of the obvious gaps. ISBN 978-0-86476-213-9 Cover image: Clianthus puniceus (kaka beak) “Lincoln University campus: a guide to some of the shrubs currently growing there” Roy Edwards May 2009 As with the first book “Lincoln University campus – a guide to some of the trees currently growing there” (April 2008) the purpose of this guide is primarily to increase the awareness for those people who are interested in plants of the Lincoln University campus. At this point in time the list is incomplete and it is my intention to hopefully add others at a later date. In this second book I have largely concentrated on shrubs and in some instances have included a few trees that were not covered in the first book. Documenting what is currently growing on the campus provides some sort of historical record and possibly the basis for some thoughts around future planting options.

    Analysis of the Physical Properties of Seeds of Selected Viburnum Species for the Needs of Seed Sorting Operations

    processes Article Analysis of the Physical Properties of Seeds of Selected Viburnum Species for the Needs of Seed Sorting Operations Zdzisław Kaliniewicz * and Dariusz J. Choszcz Department of Heavy Duty Machines and Research Methodology, University of Warmia and Mazury, 10-719 Olsztyn, Poland; [email protected] * Correspondence: [email protected]; Tel.: +48-89-523-39-34 Abstract: Viburnum is a genus of colorful and ornamental plants popular in landscape design on account of their high esthetic appeal. The physical properties of viburnum seeds have not been investigated in the literature to date. Therefore, the aim of this study was to characterize the seeds of selected Viburnum species and to search for potential relationships between their physical attributes for the needs of seed sorting operations. The basic physical parameters of the seeds of six Viburnum species were measured, and the relationships between these attributes were determined in correlation and regression analyses. The average values of the evaluated parameters were determined in the following range: terminal velocity—from 5.6 to 7.9 m s−1, thickness—from 1.39 to 1.87 mm, width— from 3.59 to 6.33 mm, length—from 5.58 to 7.44 mm, angle of external friction—from 36.7 to 43.8◦, mass—from 16.7 to 35.0 mg. The seeds of V. dasyanthum, V. lentago and V. sargentii should be sorted in air separators, and the seeds of V. lantana and V. opulus should be processed with the use of mesh screens with round apertures to obtain uniform size fractions.

Abstract: An ethnobotanical exploration was carried out in Muzaffarabad and its adjoining areas including Jhelum Valley of the District Muzaffarabad during 2010-2011. All the plants with the ethnobotanical importance were identified and segregated separately. The region is entirely mountainous, having sub-tropical to dry temperate climate with distinct seasonal variations. This study mainly focused on the information regarding traditional uses of plants over the years by local inhabitants. The informations were then confirmed by Hakims and the old people of the areas. During the survey informations were collected from various sites, i.e. Noon Bagla, Rahim Kot, Danna Kachilee, Kot Terhala, Sanwarrian, Chikar, Chikothi, Kathiee, Qazi Nag, Rashian, Daokhun, Mojee, Lamnian, Nardaggian, Pandu, Hatian Balla, Ghahi Dopatta, Chinnari, Rabanee, Bani Hafiz, Domel, Hattian Dopatta, Khanssian, Nandi Ka Sar, Sing Paharee,Nari Bela, Khalla Butt and Leepa. The plants were used medicinally and for other purposes. The investigations resulted that usually one plant or a mixture of two or more plant is used. The unplanned exploitation had resulted in the loss of medicinally important plant species.

    The Burkwood viburnum (Viburnum × burkwoodii), first developed in England, is a dependable shrub that displays great beauty while standing up to tough urban conditions. In many ways it exemplifies the best characteristics of viburnums. Its pink blooms appear for two weeks every April and are very fragrant.
