Characterization of the Response of Ornamental Graminoids to Attempted Infection by Sclerotinia sclerotiorum.
Plant disease, 2019Co-Authors: Michelle A. Grabowski, Dean K MalvickAbstract:Sclerotinia sclerotiorum causes Sclerotinia stem rot (SSR) (also called white mold), resulting in stem rot and death of many common herbaceous Ornamental plant species. Resistant plants would be useful to manage SSR; however, the host range of S. sclerotiorum is unclear. The goal of this study was to determine how the Ornamental graminoids Pennisetum glaucum, Setaria italica, Juncus inflexus, Carex flagellifera, Isolepis cernua, and Acorus gramineus respond to inoculation with S. sclerotiorum. Plants were inoculated in the field and in controlled environments at 13, 16, 19, or 22°C with or without wounding, and evaluated for SSR. Inoculated detached leaves were stained to examine infection and oxalate oxidase production. A. gramineus developed SSR in field and controlled environments. Sclerotinia stem rot was not observed on P. glaucum in field environments. The disease developed on P. glaucum and S. italica in controlled environments, and severity increased with decreasing temperature and wounding. J. inflexus, C. flagellifera, and I. cernua developed no or minor symptoms of SSR in field and controlled environments. Mycelia penetrated A. gramineus leaves 24 h after inoculation (HAI) and P. glaucum at 48 HAI, but did not penetrate J. inflexus at 24, 48, or 96 HAI. Oxalate oxidase was not detected in inoculated leaves of these Ornamental graminoids. The results illuminate S. sclerotiorum's interactions with monocots and broaden the understanding of SSR resistance in Ornamental Grasses.

High Line Park
2006Co-Authors: Büro Happold, Corner James, Diller Scofidio + Renfro, Oudolf PietAbstract:Detail, concrete "tines" weaving into planting of Ornamental Grasses; The High Line is a 1-mile (1.6 km) New York City linear park built on a 1.45-mile (2.33 km) section of the former elevated New York Central Railroad spur called the West Side Line (built 1929-1934), which runs along the lower west side of Manhattan; it has been redesigned and planted as an aerial greenway. The High Line Park currently runs from Gansevoort Street, three blocks below West 14th Street, in the Meatpacking District, up to 30th Street, through the neighborhood of Chelsea to the West Side Yard, near the Javits Convention Center. The recycling of the railway into an urban park has spurred real estate development in the neighborhoods which lie along the line. The park was designed by the New York-based landscape architecture firm James Corner Field Operations, and architects Diller Scofidio + Renfro, with planting design from Piet Oudolf of the Netherlands and engineering design by Buro Happold. The hardy, naturalized plantings are inspired by the self-seeded landscape that grew on the disused tracks. Source: Wikipedia; http://en.wikipedia.org/wiki/Main_Page (accessed 7/10/2012

Application of wood chips for soil mulching in the cultivation of Ornamental Grasses
Sciendo, 2016Co-Authors: Henschke Monika, Politycka BarbaraAbstract:A mulch is a layer of material applied to the surface of the soil. Mulching plays an important role in the maintenance of green spaces. Organic materials are still sought for the preparation of mulches. Recently interest in wood chips has grown. The aim of the study was to determine the effect of mulching with pine and birch chips on the contents of phenolic compounds in the soil, as well as on the growth and flowering of Ornamental Grasses – Bouteloua gracilis (Kunth.) Lag. ex Griffiths, Panicum virgatum L. and Pennisetum alopecuroides L. The content of phenolic compounds in the soil steadily increased from spring to autumn. Mulching led to a substantial increase in the level of phenolic compounds. In the first year of cultivation more phenolic compounds were released by chips of pine than birch, while in the second year this difference did not occur. Mulching had a negative impact on the growth and flowering of Ornamental Grasses, especially in the first year of cultivation. Ornamental grass sensitivity to the substances released from mulches decreased with the age of the plants and was dependent on the species – Bouteloua gracilis was found to be particularly sensitive

Growth of Ornamental Grasses Under Salinity Stress
Sciendo, 2016Co-Authors: Henschke MonikaAbstract:The aim of this study was to determine the effect of substrate salinity caused by increasing NaCl doses on growth and development of Ornamental Grasses: Briza media L., Deschampsia cespitosa (L.) P. Beauv., Koeleria glauca (Spreng.) DC., Sesleria caerulea (L.) Ard. and Sorghastrum nutans (L.) Nash. Results provide the basis for the preliminary classification of analyzed Grasses in terms of their tolerance to substrate salinity. Grasses, responding negatively to substrate salinity caused by small doses of 5 and 10 g·NaCl·dm−3, may be considered to be sensitive species. Within the studied genotypes, B. media showed a negative response to salt stress in most of the analyzed traits. Genotypes responded differently to salinity but all had a decreased tolerance index even at the lowest concentration of NaCl. The lowest percentages of dry leaves at 5 and 10 g NaCl·dm−3 were in K. glauca and S. caerulea. The percentage of dry matter and leaf greenness were least affected

Post-harvest longevity of Ornamental Grasses conditioned in gibberellic acid and 8-hydroxyquinoline sulphate
Sciendo, 2016Co-Authors: Henschke Monika, Pers Katarzyna, Opalińska SylwiaAbstract:Florists’ greens are becoming increasingly important in contemporary floristry. Numerous studies conducted on cut flowers have led to the development of technologies for their post-harvest handling; however, in the case of florists’ greens they are still insufficient. Moreover, the extensive range of florists’ greens lacks leaves and the leafy culms of Grasses. The aim of this study was to determine the post-harvest longevity of the leaves and leafy culms of Ornamental Grasses conditioned in water solutions of gibberellic acid and 8-hydroxyquinoline sulphate. The post-harvest longevity of leaves was examined in cultivars of the following species: Glyceria maxima Hartm. ‘Variegata’, Miscanthus sinensis Thunb. ‘Zebrinus’ and Spartina pectinata Link. ‘Aureomarginata’. The post-harvest longevity of leafy culms was investigated in Alopecurus pratensis L. ‘Aureovariegatus’, Chasmanthium latifolium Michx., Miscanthus sinensis Thunb. ‘Silberspinne’, Pennisetum alopecuroides L. and Phalaris arundinacea L. ‘Picta’. Conditioning in gibberellic acid had a positive effect on the post-harvest longevity and fresh weight loss and the index of leaf greenness of leaves in the case of Miscanthus sinensis ‘Zebrinus’, while conditioning in 8-hydroxyquinoline sulphate improved fresh weight loss and the index of leaf greenness of the leafy culms of Miscanthus sinensis ‘Zebrinus’, Pennisetum alopecuroides and the leaves of Glyceria maxima ‘Variegata’
