Introductory Grass Identification Workshop University of Houston Coastal Center 23 September 2017
Broadleaf Woodoats (Chasmanthium latifolia) Introductory Grass Identification Workshop University of Houston Coastal Center 23 September 2017 1 Introduction This 5 hour workshop is an introduction to the identification of grasses using hands- on dissection of diverse species found within the Texas middle Gulf Coast region (although most have a distribution well into the state and beyond). By the allotted time period the student should have acquired enough knowledge to identify most grass species in Texas to at least the genus level. For the sake of brevity grass physiology and reproduction will not be discussed. Materials provided: Dried specimens of grass species for each student to dissect Jewelry loupe 30x pocket glass magnifier Battery-powered, flexible USB light Dissecting tweezer and needle Rigid white paper background Handout: - Grass Plant Morphology - Types of Grass Inflorescences - Taxonomic description and habitat of each dissected species. - Key to all grass species of Texas - References - Glossary Itinerary (subject to change) 0900: Introduction and house keeping 0905: Structure of the course 0910: Identification and use of grass dissection tools 0915- 1145: Basic structure of the grass Identification terms Dissection of grass samples 1145 – 1230: Lunch 1230 - 1345: Field trip of area and collection by each student of one fresh grass species to identify back in the classroom. 1345 - 1400: Conclusion and discussion 2 Grass Structure spikelet pedicel inflorescence rachis culm collar internode ------ leaf blade leaf sheath node crown fibrous roots 3 Grass shoot.

Genetic Diversity in Centipedegrass [Eremochloa Ophiuroides (Munro
Li et al. Horticulture Research (2020) 7:4 Horticulture Research https://doi.org/10.1038/s41438-019-0228-1 www.nature.com/hortres REVIEW ARTICLE Open Access Genetic diversity in centipedegrass [Eremochloa ophiuroides (Munro) Hack.] Jianjian Li1,2, Hailin Guo1,2, Junqin Zong1,2, Jingbo Chen1,2,DandanLi1,2 and Jianxiu Liu1,2 Abstract Genetic diversity is the heritable variation within and among populations, and in the context of this paper describes the heritable variation among the germplasm resources of centipedegrass. Centipedegrass is an important warm- season perennial C4 grass belonging to the Poaceae family in the subfamily Panicoideae and genus Eremochloa.Itis the only species cultivated for turf among the eight species in Eremochloa. The center of origin for this species is southern to central China. Although centipedegrass is an excellent lawn grass and is most widely used in the southeastern United States, China has the largest reserve of centipedegrass germplasm in the world. Presently, the gene bank in China holds ~200 centipedegrass accessions collected from geographical regions that are diverse in terms of climate and elevation. This collection appears to have broad variability with regard to morphological and physiological characteristics. To efficiently develop new centipedegrass varieties and improve cultivated species by fully utilizing this variability, multiple approaches have been implemented in recent years to detect the extent of variation and to unravel the patterns of genetic diversityamongcentipedegrasscollections. In this review, we briefly summarize research progress in investigating the diversity of centipedegrass using morphological, physiological, cytological, and molecular biological approaches, and present the current status of genomic studies in centipedegrass. -
Holocene Palaeoenvironmental Reconstruction Based on Microfossil Analysis of a Lake Sediment Core, Nong Han Kumphawapi, Udon Thani, Northeast Thailand
Holocene Palaeoenvironmental Reconstruction Based on Microfossil Analysis of a Lake Sediment Core, Nong Han Kumphawapi, Udon Thani, Northeast Thailand DAN PENNY, JOHN GRINDROD, AND PAUL BISHOP FEW LATE QUATERNARY palynological studies exist for continental Southeast Asia. This is despite the fact that there is good potential for the interpretation of former environments through palynological techniques, with the considerable physiographic and climatic diversity of the region reflected in discernible floristic patterns in the existing landscape. The potential scientific value of such studies is clear given the geographical significance of the region in terms of both climate, particularly with regards to the influence of the tropical monsoon belt, and archae ology, with intensive research in recent decades into the Holocene development of centers of habitation and agriculture. Most published Holocene palynological studies in Thailand derive from low land and coastal sites in southern and central parts of the country, with few avail able for inland northern regions. Detailed coastal and near-coastal studies include those at Chanthaburi in southeast Thailand (Pramojanee and Hastings 1983), Sat ingpra (Stargardt 1983) and Narathiwat in peninsula Thailand (Hastings 1983), and Khok Phanom Di (Maloney 1991) and Senanivate Pit (Sangsuwan et al. 1987) on the southern Central Plain. These pollen records indicate local environmental effects of Holocene sea-level change on vegetation communities, largely inter preted from fluctuations in the representation of pollen from mangrove com munities, and confirm the last sea-level transgression for the Gulf of Thailand as recently as 3000 years Before Present (B.P.). Attempts to reconstruct palaeocli mates in the north and northeast of Thailand are far less common. -

Joseph 1,* , Karen Harris-Shultz 2 and David Jespersen 3 1 Department of Entomology, University of Georgia, Griffin, GA 30223, USA 2 Crop Genetics and Breeding Research Unit, USDA-ARS, Tifton, GA 31793, USA; [email protected] 3 Department of Crop and Soil Science, University of Georgia, Griffin, GA 30223, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-770-228-7312 Received: 19 October 2020; Accepted: 10 November 2020; Published: 13 November 2020 Simple Summary: Turfgrasses are generally considered devoid of pollinators, as turfgrasses are often described as being only wind-pollinated. Centipede grass is a popular turfgrass grown in the southeastern USA. Centipede grass produces a large number of inflorescences from August to October each year. In a recent study, honeybees were found to collect pollen from centipede grass. However, it is not clear whether other pollinators are attracted to centipede grass inflorescences and actively forage them. Thus, the aim of the current study was to document the pollinators that foraged on centipede grass inflorescences. Pollinators visiting centipede grass were sampled using (1) a sweep net when actively foraging on an inflorescence; (2) blue, white and yellow pan traps; and (3) malaise or flight-intercept traps. Sweat-, bumble- and honeybees were captured while actively foraging on the centipede grass inflorescences. In the pan and flight-intercept traps, more sweat-bees were collected than honey- or bumblebees. We also captured hoverflies in the samples. The adult hoverflies consumed pollen during flower visits. This research is a first step toward developing bee-friendly lawns. -
