Effects of Agronomic Treatments on Silphium Integrifolium, a Potential Perennial Oilseed
Effects of Agronomic Treatments on Silphium integrifolium, a Potential Perennial Oilseed A Thesis SUBMITTED TO THE FACULTY OF THE GRADUATE SCHOOL OF THE UNIVERSITY OF MINNESOTA BY Sydney A. Schiffner IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE Craig C. Sheaffer, Advisor August 2018 © Sydney Schiffner 2018 Acknowledgements I would first like to thank my advisor, Dr. Craig Sheaffer, for allowing me to pursue a degree in Applied Plant Sciences on the Agronomy/Agroecology track within his lab. I would next like to thank Dr. Jacob Jungers, and Dr. Nicole Tautges for their assistance with interpreting findings and help with statistical analysis on my data. Next I would like to thank lab technicians Joshua Larson, Lindsay Wilson and Donn Vellekson for their assistance in field management and data collection. Thanks also to the Sustainable Cropping System/Forages lab and all of the interns and MAST students that helped make my research possible with their dedication to good science and field research. This project was funded by the Malone Foundation through The Land Institute, and I would like to thank Dr. David Van Tassel at The Land Institute for being on call whenever I had any odd question about silphium. Thank you to my friends and family who have supported me through this rigorous scientific endeavor, and last of all thank you to my fellow graduate students. Without your fellowship for the past few years, I definitely wouldn’t have made it through graduate school, or had as much of a fun time going through it. -

SMOOTH OXEYE Fibrous Rooted Caudex That Develops Stout Rhizomes
Plant Guide (m) in height. The smooth, unbranched stem arises from a SMOOTH OXEYE fibrous rooted caudex that develops stout rhizomes. The leaves are oppositely attached to the stem and have Heliopsis helianthoides (L.) Sweet coarsely serrated margins. The leaves are triple nerved, Plant Symbol = HEHE5 petiolate (have short leaf petioles) and are broadly lance shaped tapering to a sharp point at the tip and are abruptly Contributed by: USDA NRCS Manhattan Plant Materials rounded at the base. The leaves are dark green above and Center lighter green below with siliceous based hairs that provide a rough texture on both surfaces. The stem apex may contain a single flower head or branch into multiple stems with many yellow flowers (Owensby, 1989). The flowers of Heliopsis have both orange-yellow center disk and yellow ray flowers. Individual flowers have 10 or more ray flowers. The ray flowers are fertile with a forked pistil (female flower parts) at their base, but contain no male flower parts (Lommasson, 1973). The central disk flowers are perfect in that they contain both male and female flower parts (Runkel and Roosa, 1989). The fruit is a smooth three or four angled achene, usually without a pappus or crown of hairs that aids in wind dissemination (Runkel and Roosa, 1989). Ray flowers produce the three angled achene and disk flower produce the more common 4 angled achene.

Working List of Prairie Restricted (Specialist) Insects in Wisconsin (11/26/2015)
Working List of Prairie Restricted (Specialist) Insects in Wisconsin (11/26/2015) By Richard Henderson Research Ecologist, WI DNR Bureau of Science Services Summary This is a preliminary list of insects that are either well known, or likely, to be closely associated with Wisconsin’s original native prairie. These species are mostly dependent upon remnants of original prairie, or plantings/restorations of prairie where their hosts have been re-established (see discussion below), and thus are rarely found outside of these settings. The list also includes some species tied to native ecosystems that grade into prairie, such as savannas, sand barrens, fens, sedge meadow, and shallow marsh. The list is annotated with known host(s) of each insect, and the likelihood of its presence in the state (see key at end of list for specifics). This working list is a byproduct of a prairie invertebrate study I coordinated from1995-2005 that covered 6 Midwestern states and included 14 cooperators. The project surveyed insects on prairie remnants and investigated the effects of fire on those insects. It was funded in part by a series of grants from the US Fish and Wildlife Service. So far, the list has 475 species. However, this is a partial list at best, representing approximately only ¼ of the prairie-specialist insects likely present in the region (see discussion below). Significant input to this list is needed, as there are major taxa groups missing or greatly under represented. Such absence is not necessarily due to few or no prairie-specialists in those groups, but due more to lack of knowledge about life histories (at least published knowledge), unsettled taxonomy, and lack of taxonomic specialists currently working in those groups. -
Wild Helianthus Anomalus and H. Deserticola from the Desert Southwest USA: a Potential Source of Stress Genes for Cultivated Sunflower
Wild Helianthus anomalus and H. deserticola from the Desert Southwest USA: a Potential Source of Stress Genes for Cultivated Sunflower Gerald J. Seiler U.S. Department of Agriculture, Agricultural Research Service, Northern Crop Science Laboratory, Fargo, North Dakota USA 58105 www.fargo.ars.usda.gov Email [email protected] Abstract The narrow genetic base of cultivated sunflower has been broadened by the infusion of genes from wild species, which continue to be a valuable source of desirable agronomic traits. Helianthus anomalus Blake is a wild annual species adapted to sandy dunes of the southwest USA. Helianthus deserticola Heiser is another wild annual species adapted to high desert areas of the same region. The adaptation of these species to harsh habitats makes them potential candidates for improving stress tolerance in the cultivated sunflower crop. Since seed of these species was not available in the USDA-ARS Sunflower Germplasm Collection, an exploration was undertaken in September, 2000 to collect populations for future research. Due to the extremely dry weather in 2000, only two populations of H. anomalus and one H. deserticola were collected. These collections are the first populations of these species added to the sunflower collection in over 20 years. Future research calls for introgression of the wild species into cultivated sunflower and evaluating the progeny for ecophysiological characteristics. Media summary Wild annual sunflowers from the southwestern deserts of the USA have the potential to improve stress tolerance in cultivated sunflower. Key Words Exploration, drought, ecophysiological, germplasm, genetic diversity. Introduction The genus Helianthus is comprised of 51 species with 14 annual and 37 perennial, all native to North America. -

Southwestern Rare and Endangered Plants
The Importance of Competition in the Isolation and Establishment of Helianthus Paradoxus (Asteraceae) 1 OSCAR W. VAN AUKEN AND JANIS. K. BUSH Department of Earth and Environmental Sciences, University of Texas at San Antonio, San Antonio, TX 78249 1Author for correspondence and reprints. FAX 210-458-5658; E-mail [email protected] ABSTRACT: Helianthus paradoxus (the Pecos or puzzle sunflower) is a threatened, federally listed annual species that is found in a few locations in west Texas and New Mexico. Two greenhouse experiments were conducted to evaluate the ability of H. paradoxus to compete with its progenitors and a with potential ecosystem competitor, Distichlis spicata (saltgrass) in simulated salt marsh and non-salt marsh environments. The results were usually dependent on soil salinity. Helianthus paradoxus was the better competitor in high saline soil and its progenitor H. annuus (common sunflower) was the better competitor in low saline soil. However, H. paradoxus was the better competitor in both high and low saline soils when compared to it progenitor H. petiolaris (plains sunflower) and to D. spicata, an ecosystem competitor. The ability of H. paradoxus to tolerate higher saline conditions, and perhaps even restrict the more geographically widespread H. annuus in saline soils may have allowed H. paradoxus to establish, become genetically isolated and survive as a species in inland salt marshes. Data presented here indicate that while H. paradoxus can grow in low saline soil, interference from H. annuus in low saline soils could restrict H. paradoxus to saline environments within salt marshes. The ability of H. paradoxus to out-compete D. -

The Jerusalem Artichoke: Something New for Next Year's Garden?
The Jerusalem Artichoke: Something New for Next Year’s Garden? By Joan Allen If you’re a gardener who likes to grow new vegetables, use native plants or support beneficial insects season-long, the Jerusalem artichoke (Helianthus tuberosus) might be fun to try. As a member of the sunflower genus, this plant produces tall stems topped with bright yellow flowers. There are a few different theories on the origin of the name, which is a curiosity since it’s native to eastern North American. The most popular seems to be that ‘Jerusalem’ is an American twist on the Italian ‘girasole’ meaning ‘turning to the sun’. Other common names include sunchoke, earth apple or topinambour (French). Plants reach a height of 5-10 feet and produce flowers from August to October, providing a nice source of pollen and nectar for beneficial insects late in the season. The plants are sturdy and rather coarse. Leaves are 4-10” long, thick and rough, and have toothed edges. They are opposite on the lower stem and alternate above. Flowers are 3” across. This plant will do well in gardens in the northern two thirds of the eastern United States and tolerates a wide range of soil types and pH, although a bit alkaline is preferred. Soil should be well drained. A consistent water supply is especially important as the tubers (edible part) develop late in the summer. This is a VERY prolific plant. According to one reference, a single root can produce as many as 75-200 new tubers in a single year. On top of that, the plant is perennial and tends to spread, so it can become a bit of a problem in limited spaces if not kept in check.
