Klimato šiltėjimo sąlygoti introdukuotų spygliuočių rūšių pumpurų brinkimo fenofazės pokyčiai atsižvelgiant į jų natūralių arealų atšiauraus klimato zonas
'Lithuanian Academy of Sciences', 2017Co-Authors: Malakauskienė Asta, Vitas AdomasAbstract:Besikeičiančios klimatinės sąlygos lemia medžių fe-nologijos pokyčius, kurie yra svarbūs rūšių išlikimui bei paplitimui vietinėse ekosistemose. Šio tyrimo tikslas – pagal ilgalaikių stebėjimų (1957–2016 m. arba 1980–2016 m.) duomenis įvertinti 11 spygliuo-čių medžių rūšių, introdukuotų Lietuvoje, pumpurų brinkimo fenofazės atsaką į klimato šiltėjimą atsi-žvelgiant į jų natūralių arealų atšiauraus klimato zo-nas.Analizuotos 11 introdukuotų spygliuočių rūšių (Abies veitchii, Larix decidua, L.kaempferi, L.la-ricina, L. × marschlinsii, L.sibirica, L.sukaczewii, Picea mariana, Pinus mugo, Taxus baccata ir Thuja occidentalis) pumpurų brinkimo fenofazės pradžios datų sekos. Rezultatai rodo, kad 10-ies į Lietuvą introdukuotų spygliuočių medžių rūšių pumpu-rų brinkimo fenofazė paankstėjo (pokyčių greitis svyravo nuo –0,10 iki –0,98 dienos / metus 1980–2016 m.), o Larix sukaczewii pumpurų brinkimo fenofazė vėlavo (atitinkamai +0,12 dienos / metus), ir tai daugiausia lėmė kovo mėnesio temperatūra.Ryšys tarp stebėtų spygliuočių medžių rūšių natūra-lių arealų atšiauraus klimato zonų ir pumpurų brin-kimo fenofazės reakcijos į klimato šiltėjimą buvo pastebėtas tik lyginant vienos genties rūšisBackground. Changing climatic conditions cause changes in tree phenology, which is important for the survival of species and their spread in local ecosystems. This study concentrated on long-term (1957–2016 or 1980–2016) observations of 11 conifer species introduced to Lithuania with the aim to evaluate the response of their bud swelling phenophase to climate warming, considering the Hardiness Zones of their natural habitats. Materials and Methods. Sequences of the start date of the bud swelling phenophase of 11 introduced conifer species (Abies veitchii, Larix decidua, L. kaempferi, L. laricina, L. × marschlinsii, L. sibirica, L. sukaczewii, Picea mariana, Pinus mugo, Taxus baccata and Thuja occidentalis) were analysed. Data were collected from the paper archives of Kaunas Botanical Garden of Vytautas Magnus University (VMU). Sequences of bud swelling start dates were transformed into sequences of number of days from the beginning of the year. Results. Results indicated an advance of the bud swelling phenophase of ten conifer species introduced to Lithuania (the speed of changes varied from –0.10 to –0.98 days/year in the 1980–2016 period) and a delay of Larix sukaczewii (respectively, +0.12 days/ year) of the bud swelling phenophase, mainly influenced by the March temperature. Conclusions. The connection between the observed conifer species Hardiness Zone of the natural habitat and the reaction of the bud swelling phenophase to climate warming could be observed only when species from one genus were compared. To confirm this phenomenon, a research on a larger amount of introduced species with wider habitat Hardiness Zone options is needed in futureAplinkos tyrimų centrasBotanikos sodasVytauto Didžiojo universiteta

development of a new usda plant Hardiness Zone map for the united states
Journal of Applied Meteorology and Climatology, 2012Co-Authors: Christopher Daly, Mark P Widrlechner, Michael D Halbleib, Joe Smith, Wayne GibsonAbstract:AbstractIn many regions of the world, the extremes of winter cold are a major determinant of the geographic distribution of perennial plant species and of their successful cultivation. In the United States, the U.S. Department of Agriculture (USDA) Plant Hardiness Zone Map (PHZM) is the primary reference for defining geospatial patterns of extreme winter cold for the horticulture and nursery industries, home gardeners, agrometeorologists, and plant scientists. This paper describes the approaches followed for updating the USDA PHZM, the last version of which was published in 1990. The new PHZM depicts 1976–2005 mean annual extreme minimum temperature, in 2.8°C (5°F) half Zones, for the conterminous United States, Alaska, Hawaii, and Puerto Rico. Station data were interpolated to a grid with the Parameter-Elevation Regressions on Independent Slopes Model (PRISM) climate-mapping system. PRISM accounts for the effects of elevation, terrain-induced airmass blockage, coastal effects, temperature inversions, and...

Registration of ‘Homestead’ Canada Wildrye
DigitalCommons@University of Nebraska - Lincoln, 2010Co-Authors: Vogel, Kenneth P., Mitchell R. B., Baltensperger D. D., Johnson K. D., Carlson I. T.Abstract:‘Homestead’ (Reg. No. CV-255, PI 655522) Canada wildrye (Elymus canadensis L.) was developed cooperatively by USDA-ARS and the University of Nebraska and was released in 2008 for use in the Great Plains and the Midwest USA, a region for which no adapted cultivars were previously available. It was developed by means of the Ecotype Selection Breeding System from a collection made in a remnant prairie in Eastern Nebraska USA. Homestead, which was tested as NE3, is adapted to Plant Adaptation Region (PAR) 251-5 (Temperate Prairie Parkland–Plant Hardiness Zone 5), which is its origin, and in which it has been evaluated in both space-transplanted and sward trials. This region is equivalent to USDA Plant Hardiness Zone 5 of the tallgrass-prairie ecoregion of the Midwest, USA. When grown in its area of adaptation, it produces more forage than the previously available, unadapted cultivar of the species and its forage has higher in vitro dry matter digestibility than another adapted experimental strain to which it was compared in sward forage yield trials. Its primary use will be as a native cool-season grass component of conservation, roadside, and grassland seeding mixtures

Registration of ‘Warrior’, ‘Scout’, and ‘Chief’ Indiangrass
DigitalCommons@University of Nebraska - Lincoln, 2010Co-Authors: Vogel, Kenneth P., Mitchell R. B., Gorz H. J., Haskins Francis, Newell L. C., Klopfenstein, Terry J., Erickson Galen, Anderson BruceAbstract:‘Warrior’ (Reg. No. CV-252, PI 655523), ‘Scout’ (Reg. No. CV-253, PI 655524), and ‘Chief’ (Reg. No. CV-254, PI 655525) indiangrass [Sorghastrum nutans (L.)] Nash were developed for improved yield and forage digestibility by USDA-ARS and the University of Nebraska for use in the central Great Plains and the Midwest USA. Warrior was tested as Oto C3 and was developed by means of both half-sib family selection and restricted, recurrent phenotypic selection (RRPS). Scout and Chief which were tested as NE54 C2 and Holt × Oto Early C2, respectively, were developed by RRPS. Warrior is adapted to USDA Plant Hardiness Zone (HZ) 5 and the upper part of HZ 6 in the Great Plains and Midwest. It produces forage with high in vitro dry matter digestibility (IVDMD) that results in improved animal gains when utilized by beef cattle in well managed grazing systems in regions where it is adapted. Scout is adapted to HZ 5 in the Great Plains and Midwest, USA. It produces signifi cantly greater forage yields than other adapted indiangrass cultivars when grown for hay in the western part of its adaptation region. Chief is adapted to HZ 4 and the upper half of HZ 5. It produces signifi cantly greater forage yields than the other available HZ 4 cultivars. Warrior, Scout, and Chief represent the second generation of indiangrass cultivars developed for use in production agriculture. In the regions where they are adapted, these cultivars can be used in pure stands or in multispecies mixtures with other grasses

Latitudinal and Longitudinal Adaptation of Switchgrass Populations
DigitalCommons@University of Nebraska - Lincoln, 2007Co-Authors: Casler, Michael D., Vogel, Kenneth P., Taliaferro C. M., Ehlke N. J., Berdahl J. D., Brummer E. C., Kallenbach R. L., West C. P., Mitchell R. B.Abstract:Switchgrass (Panicum virgatum L.) is a warmseason native grass, used for livestock feed, bioenergy, soil and wildlife conservation, and prairie restoration in a large portion of the USA. The objective of this research was to quantify the relative importance of latitude and longitude for adaptation and agronomic performance of a diverse group of switchgrass populations. Six populations, chosen to represent remnant prairie populations on two north–south transects, were evaluated for agronomic traits at 12 locations ranging from 36 to 47°N latitude and 88 to 101°W longitude. Although the population × location interactions accounted for only 10 to 31% of the variance among population means, many significant changes in ranking and adaptive responses were observed. Ground cover was greater for northern-origin populations evaluated in Hardiness Zones 3 and 4 and for southern-origin populations evaluated in Hardiness Zones 5 and 6. There were no adaptive responses related to longitude (ecoregion). Switchgrass populations for use in biomass production, conservation, or restoration should not be moved more than one Hardiness Zone north or south from their origin, but some can be moved east or west of their original ecoregion, if results from field tests support broad longitudinal adaptation

Plant Adaptation Regions: Ecological and Climatic Classification of Plant Materials
'Elsevier BV', 2005Co-Authors: Vogel K. P., Schmer M. R., Mitchell R. B.Abstract:The effective use of plant materials for an array of objectives including conservation, restoration, renovation, landscaping, and bioremediation requires knowledge of the adaptation of each species and, more specifically, knowledge of the adaptation of cultivars, strains, accessions, or ecotypes of a species to specific sites or regions. For agronomic and horticultural plants, specific adaptation information has been and continues to be developed by extensive testing. Rangeland, grassland, park, and restoration project managers often lack the resources to determine adaptation areas for plant materials because of the large number of species that are used and the extensive geographical areas that are serviced. Problems often arise in delineating adaptation areas for plant materials of both native and introduced species. Since ecoregion and plant Hardiness Zone classification systems integrate many climatic and geographic variables that determine plant adaptation, these 2 systems can be combined to develop Plant Adaptation Regions (PARs). A PAR map of the contiguous United States was developed by merging a widely used ecoregion map with the USDA Plant Hardiness Zone map, and is available in GIS format. Based on their geographic origins and/or test results, plant materials and their general areas of adaptation can be classified using PARs. The Rangeland Ecology & Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
