ALLELOPATHIC EFFECT of INVASIVE SPECIES GIANT GOLDENROD (SOLIDAGO GIGANTEA AIT.) on CROPS and WEEDS* Renata Baličević, Marija
Herbologia, Vol. 15, No. 1, 2015 DOI 10.5644/Herb.15.1.03 ALLELOPATHIC EFFECT OF INVASIVE SPECIES GIANT GOLDENROD (SOLIDAGO GIGANTEA AIT.) ON CROPS AND WEEDS* Renata Baličević, Marija Ravlić, Tea Živković* Faculty of Agriculture, Josip Juraj Strossmayer University of Osijek, Kralja Petra Svačića 1d, 31000 Osijek, Croatia, corresponding author: [email protected] *Student, Graduate study Abstract The aim of the study was to determine allelopathic potential of inva- sive species giant goldenrod (Solidago gigantea Ait.) on germination and initial growth crops (carrot, barley, coriander) and weed species velvetleaf (Abutilon theophrasti Med.) and redroot pigweed (Amaranthus retroflexus L.). Experiments were conducted under laboratory conditions to determine effect of water extracts in petri dish bioassay and in pots with soil. Water extracts from dry aboveground biomass of S. gigantea in concentrations of 1, 5 and 10% were investigated. In petri dish bioassay, all extract con- centrations showed allelopathic effect on germination and seedling growth of crops with reduction over 25 and 60%, respectively. Both weed species germination and growth were greatly suppressed with extract application. In pot experiment, allelopathic effect was less pronounced. Reduction in emergence percent, shoot length and fresh weight of carrot were observed. Barley root length and fresh weight were reduced with the highest extract concentration. No significant effect on seedling emergence and growth of A. theophrasti was recorded, while emergence of A. retroflexuswas inhib- ited for 14.4%. Germination and growth of test species decreased propor- tionately as concentration of weed biomass in water extracts increased. Differences in sensitivity among species were recorded, with A. retroflexus being the most susceptible to extracts. -

The national park was F E R N S established in 1968. In 1994, a cooperative agreement with the California Department of Parks and Recreation added Del Norte Coast, Prairie Creek, Athyriaceae – Lady Fern Family and Jedediah Smith Redwoods state parks to form a single administrative Athyrium filix-femina var. cyclosporum • northwestern lady fern unit. Together they comprise about 133,000 acres (540 km2), including 37 miles of coast line. Almost half of the remaining old growth redwood forests Blechnaceae – Deer Fern Family are protected in these four parks. -
Comparative Anatomy of Ovules in Galinsoga, Solidago and Ratibida (Asteraceae)
ACTA BIOLOGICA CRACOVIENSIA Series Botanica 56/2: 115–125, 2014 DOI: 10.2478/abcsb-2014-0024 COMPARATIVE ANATOMY OF OVULES IN GALINSOGA, SOLIDAGO AND RATIBIDA (ASTERACEAE) JOLANTA KOLCZYK1, PIOTR STOLARCZYK2, AND BARTOSZ J. PŁACHNO1* 1Department of Plant Cytology and Embryology, Jagiellonian University, Gronostajowa 9, 30-387 Cracow, Poland 2Unit of Botany and Plant Physiology, Institute of Plant Biology and Biotechnology, University of Agriculture in Cracow, Al. 29 Listopada 54, 31-425 Cracow, Poland Manuscript submitted September 9, 2014; revision accepted October 22, 2014 Many Asteraceae species have been introduced into horticulture as ornamental or interesting exotic plants. Some of them, including Solidago and Galinsoga, are now aggressive weeds; others such as Ratibida are not. Special modifications of the ovule tissue and the occurrence of nutritive tissue have been described in several Asteraceae species, including invasive Taraxacum species. This study examined whether such modifications might also occur in other genera. We found that the three genera examined – Galinsoga (G. quadriradiata), Solidago (S. canadensis, S. rigida, S. gigantea) and Ratibida (R. pinnata) – differed in their nutritive tissue structure. According to changes in the integument, we identified three types of ovules in Asteraceae: “Taraxacum” type (recorded in Taraxacum, Bellis, Solidago, Chondrilla), with well-developed nutritive tissue having very swollen cell walls of spongy structure; “Galinsoga” type (in Galinsoga), in which the nutritive tissue cells have more cyto- plasm and thicker cell walls than the other integument parenchyma cells, and in which the most prominent character of the nutritive tissue cells is well-developed rough ER; and “Ratibida” type (in Ratibida), in which the nutritive tissue is only slightly developed and consists of large highly vacuolated cells. -

Native Plant List, Pdf Format
Appendix A: City of Bellingham Native Plant List December 2020 The City of Bellingham Native Plant List (Figure 1) includes plant species that are native to Bellingham watersheds (Figure 2). The native plant list applies to all habitat types, including riparian, upland, and wetland areas. The list was developed using specimen records from the Consortium of Pacific Northwest Herbaria and Bellingham plant checklists curated by Don Knoke, a volunteer at the University of Washington Herbarium. To improve plant establishment and protect the genetic resources of our local plant populations, the City recommends using native plants that were grown from seeds or cuttings collected from the Puget Trough Ecoregion (Figure 3). Obtaining native plants grown from material collected from the Puget Trough Ecoregion will help ensure the plants are adapted to the unique environmental conditions of Bellingham watersheds and are genetically similar to our local plant populations. A more thorough discussion of the rational and selection process is provided in the City of Bellingham Public Works Department Native Plant Materials Selection Guidelines, December 2020. Figure 1.

SOLIDAGO BRENDIAE ABSTRACT a New Species of S
Semple, J.C. 2013. A new species of Triplinerviae goldenrod in eastern Canada (Asteraceae: Astereae): Solidago brendiae . Phytoneuron 2013-57: 1–9. Published 21 August 2013 ISSN 2153 733X A NEW SPECIES OF TRIPLINERVIAE GOLDENROD IN EASTERN CANADA (ASTERACEAE: ASTEREAE): SOLIDAGO BRENDIAE JOHN C. SEMPLE Department of Biology University of Waterloo Waterloo, Ontario Canada N2L 3G1 [email protected] ABSTRACT A new species of Solidago is described from collections made in Maritime Canada. Fernald (1915, 1950) treated some of these plants as S. lepida var. elongata , which is native to far western North America. Comparison of these entire to sharply and coarsely serrate narrower leaved specimens that are sparsely hairy to glabrate with S. canadensis and the broader leaved and sometimes more hairy specimens of the S. lepida complex from Quebec, Newfoundland, New Brunswick, Nova Scotia, and Prince Edward Island indicate that Fernald was correct in recognizing two closely related races native to the Canadian Maritimes that are similar to the mostly western S. lepida, but they are treated here as varieties of S. fallax. Fernald was incorrect in thinking that the narrower leaved race belonged in S. elongata . These three eastern taxa are diploid while the S. lepida infrequently occurring in the Maritimes is hexaploid. All four taxa are usually more stipitate- glandular and have more leafy inflorescences with ascending branches than in sometimes similar S. canadensis . The following new name and combinations are proposed: Solidago brendiae Semple, sp. nov. , Solidago fallax (Fernald) Semple, comb. et stat. nov. , and Solidago fallax var. molina (Fernald) Semple, comb. nov.

Species Accounts
Species accounts The list of species that follows is a synthesis of all the botanical knowledge currently available on the Nyika Plateau flora. It does not claim to be the final word in taxonomic opinion for every plant group, but will provide a sound basis for future work by botanists, phytogeographers, and reserve managers. It should also serve as a comprehensive plant guide for interested visitors to the two Nyika National Parks. By far the largest body of information was obtained from the following nine publications: • Flora zambesiaca (current ed. G. Pope, 1960 to present) • Flora of Tropical East Africa (current ed. H. Beentje, 1952 to present) • Plants collected by the Vernay Nyasaland Expedition of 1946 (Brenan & collaborators 1953, 1954) • Wye College 1972 Malawi Project Final Report (Brummitt 1973) • Resource inventory and management plan for the Nyika National Park (Mill 1979) • The forest vegetation of the Nyika Plateau: ecological and phenological studies (Dowsett-Lemaire 1985) • Biosearch Nyika Expedition 1997 report (Patel 1999) • Biosearch Nyika Expedition 2001 report (Patel & Overton 2002) • Evergreen forest flora of Malawi (White, Dowsett-Lemaire & Chapman 2001) We also consulted numerous papers dealing with specific families or genera and, finally, included the collections made during the SABONET Nyika Expedition. In addition, botanists from K and PRE provided valuable input in particular plant groups. Much of the descriptive material is taken directly from one or more of the works listed above, including information regarding habitat and distribution. A single illustration accompanies each genus; two illustrations are sometimes included in large genera with a wide morphological variance (for example, Lobelia). -
Allelopathic Effect of Invasive Species Giant Goldenrod (Solidago Gigantea Ait.) on Wheat and Scentless Mayweed
8th international scientific/professional conference SECTION II Izvorni znanstveni rad / original scientific paper Allelopathic effect of invasive species giant goldenrod (Solidago gigantea Ait.) on wheat and scentless mayweed Marija Ravlić1, Renata Baličević1, Ana Peharda2 1Faculty of Agriculture, Josip Juraj Strossmayer University of Osijek, Kralja Petra Svačića 1d, Osijek, Croatia, e-mail: [email protected] 2Student, Faculty of Agriculture, Osijek, Croatia Abstract The aim of the research was to determine allelopathic potential of invasive species giant gol- denrod (Solidago giganetea Ait.) on germination and initial growth of wheat and weed species scentless mayweed (Tripleurospermum inodorum (L.) C.H. Schultz). Experiments were conducted under laboratory conditions to determine effect of water extracts in petri dish bioassay and in pots with soil. Water extracts from dry aboveground biomass of S. gigantea in concentrations of 1, 5 and 10 % (10, 50 and 100 g/l) were investigated. In petri dish bioassay, germination of wheat was slightly reduced, while all extract concentration inhibited wheat growth. T. inodorum germination and seedling growth was affected with higher extract concentration. Application of extract to pots had no effect on wheat emergence and growth, with the exception of 10 % extract which reduced root length. Emergence of T. inodorum was significantly decreased with 5 and 10 % extract for 38.5 and 49.0 %, respectively. Key words: allelopathy, Solidago gigantea Ait., crops, scentless mayweed, water extracts Introduction Excessive use of herbicides in most weed management systems is a major concern since it causes serious threats to the environment, public health and increases costs of crop production. The degree of weed seed germination inhibition and growth suppression which can be attributed to crop allelopathy is highly important and can be considered as a possible alternative weed management strategy (Asghari and Tewari, 2007., Macias, 1995.).
