"National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment. -

Weathering Behaviour of Cunninghamia Lanceolata (Lamb.) Hook
Article Weathering Behaviour of Cunninghamia lanceolata (Lamb.) Hook. under Natural Conditions Xinjie Cui 1 and Junji Matsumura 2,* 1 Graduate School of Bioresource and Bioenvironmental Sciences, Faculty of Agriculture, Kyushu University, 744 Motooka, Nishi-ku, Fukuoka 819-0395, Japan; [email protected] 2 Laboratory of Wood Science, Faculty of Agriculture, Kyushu University, 744 Motooka, Nishi-ku, Fukuoka 819-0395, Japan * Correspondence: [email protected]; Tel.: +81-092-802-4656 Received: 18 July 2020; Accepted: 10 December 2020; Published: 14 December 2020 Abstract: Information on the weathering behaviour of Cunninghamia lanceolata (Lamb.) Hook. is needed to provide references for wood weatherproof pre-treatment and to improve wood utilization. Therefore, this study was conducted to understand the variation in the intrinsic weathering behaviour of Cunninghamia lanceolata (Chinese fir) under natural conditions. Wood samples from 15 Cunninghamia lanceolata trees aged 26–30 years old were used. The structural degradation and discoloration of wood surfaces before and after exposure were compared. The results show that the weathering behaviour of wood was weakened from heartwood to sapwood and enhanced from the bottom to the top. This study provided information for weatherability research and improved wood utilization of Cunninghamia lanceolata. Keywords: Cunninghamia lanceolata; weathering; density; colour change; wood structure 1. Introduction Cunninghamia lanceolata (Lamb.) Hook. is a member of the family Cupressaceae. It is an evergreen tree that can grow up to 50 m in height and over 3 m in diameter. It forms mixed broad-leaved forests or small, pure stands, rocky hillsides, roadsides, with altitudes ranging from 200 to 2800 m [1]. -
Understanding the Weedy Chenopodium Complex in the North Central States
UNDERSTANDING THE WEEDY CHENOPODIUM COMPLEX IN THE NORTH CENTRAL STATES BY SUKHVINDER SINGH DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Crop Sciences in the Graduate College of the University of Illinois at Urbana-Champaign, 2010 Urbana, Illinois Doctoral Committee: Professor Patrick J. Tranel, Chair Associate Professor Aaron G. Hager Associate Professor Geoffrey A. Levin Assistant Professor Matthew E. Hudson ABSTRACT The genus Chenopodium consists of several important weed species, including Chenopodium album, C. berlandieri, C. strictum, and C. ficifolium. All of these species share similar vegetative morphology and high phenotypic plasticity, which makes it difficult to correctly identify these species. All of these weedy Chenopodium species have developed resistance to one or more classes of herbicides. An experiment was conducted to determine if there is variability in response of Chenopodium species present in the North Central states to glyphosate. Our results indicate variable responses within and among the Chenopodium species. Species such as C. berlandieri and C. ficifolium had higher levels of tolerance to glyphosate than did various accessions of C. album. In another experiment, 33 populations of Chenopodium sampled across six North Central states were screened with glyphosate. The results showed variable responses to glyphosate within and among the Chenopodium populations. In general, the Chenopodium populations from Iowa were more tolerant, but some biotypes from North Dakota, Indiana and Kansas also had significantly high tolerance to glyphosate. Given there are species other than C. album that have high tolerance to glyphosate, and there are Chenopodium populations across the North Central states that showed tolerance to glyphosate, one intriguing question was to whether the Chenopodium populations were either biotypes of C. -

SEEDS The Yearbook of Agriculture 1961 ¿^ f i Í THE UNITED STATES GOVERNMENT PRINTING OFFICE FOR SALE BY THE SUPERINTENDENT OF DOCUMENTS, WASHINGTON 25, D.G., PRICE $2 FOREWORD ORVILLE L. FREEMAN Secretary of Agriculture GOOD SEEDS ARE both a symbol and a foundation of the good Ufe our people have gained. A baisic factor in our realization of mankind's most sought goal, agricultural abundance, good seeds can be a means of our bringing about an Age of Plenty and an Age of Peace and Free- dom. We can use our good seeds to help end hunger and fear for the less fortunate half of the human family. So used, our seeds can be more meaningful to a hungry world than can the rocket that first carries man to the moon. This Yearbook of Agriculture seeks to provide a new and improved basis for understanding the complex order of Nature's forces so that man can better shape them in a positive and creative fashion. Seeds are ever a positive and creative force. Seeds are the germ of life, a beginning and an end, the fruit of yesterday's harvest and the promise of tomorrow's. Without an ample store of seeds there can be no national treasure, or no future for a Nation. Finding and developing better seeds is the oldest continuous service our Federal Government has rendered to our farmers—indeed, to all our people. -

The most common origin is Mexico, accounting for 65% of all records. Other common origin/host combinations are listed here: Origin Host(s) Fig. 3: Late instar, lateral view Colombia Alstroemeria, Chrysanthemum, Gerbera Dominican Republic Capsicum Mexico Apium, Brassica, Capsicum, Gladiolus, Ocimum, Zea mays Recorded distribution Spodoptera frugiperda is widely distributed throughout North, Central, and South America. It is also present in the Caribbean (Pogue 2002). Fig. 4: Cuticle texture Fig. 5: Crochets Identifcation authority (Summary) Spodoptera frugiperda is highly polyphagous, thus host data often does not help identification. Origin data is useful because this species does not naturally occur outside of the New World. The morphological characters listed here should be sufficient to identify S. frugiperda to species, even in early instars. -

Plantations Received 13 April 2009 established in subtropical China since the 1980s, mainly of Chinese fir (Cunninghamia lanceolata (Lamb.) Received in revised form 9 June 2009 Hook) in monocultures, have proved to be major C sinks. However, information is lacking about whether Accepted 27 June 2009 mixing Chinese fir with broadleaved tree species will increase stand growth and C sequestration. We address this question by comparing a pure Chinese fir plantation and two mixed plantations established Keywords: in 1990 at Huitong Experimental Station of Forest Ecology, Hunan Province, China. The mixed Carbon storage plantations include Chinese fir and either Kalopanax septemlobus (Thunb.) Koidz or Alnus cremastogyne Mixed plantation Burk., planted at 4:1 ratios. We found that total C storage was 123, 131 and 142 Mg haÀ1 in the pure Broadleaved tree Coniferous plantation plantation, mixed plantation with K. septemlobus, and mixed plantation with A. cremastogyne, respectively.
