Flatsedge (Cyperus Fuscus)
Invasive Plant Science and Management 2010 3:240–245 Spread, Growth Parameters, and Reproductive Potential for Brown Flatsedge (Cyperus fuscus) Charles T. Bryson and Richard Carter* Brown flatsedge (Cyperus fuscus) is widely distributed in Europe, Asia, the Indian subcontinent, and the Mediterranean region of Northern Africa. It was apparently introduced into North America in the late 1800s and has steadily moved southward and westward. Brown flatsedge is reported new to Arkansas and Mississippi herewith. Field observations from early spring until frost were made between 2003 and 2007 from populations present at three sites: Chicot County, Arkansas, and Pearl River and Washington counties, Mississippi. Under natural field conditions, brown flatsedge plants germinated from late March and early April until frost. Inflorescences were observed in mid-May and seed production continued until frost. In field populations, the average numbers of scales per spikelet, inflorescences per plant, and spikelets per inflorescence were 15, 28, and 33, respectively. Greenhouse experiments were established in 2008 at Stoneville, MS, to determine growth parameters and the reproductive potential of brown flatsedge. In greenhouse experiments, by 10 wk after emergence (WAE), brown flatsedge plants were 30.2 cm tall and 63.9 cm in diameter, and dry weights were 1.4, 1.0, 2.0, 0.5, and 1.9 g for roots, culms, leaves, bracts, and inflorescences, respectively. Brown flatsedge culms and inflorescences appeared 5 WAE, and by 9 WAE all plants were producing seed. Brown flatsedge could pose a threat to natural plant communities and rice agriculture in Arkansas, Louisiana, Mississippi, Missouri, Tennessee, and Texas. Additional research is needed to determine seed longevity and ecological range potential, and to develop inexpensive and effective control methods. -

(Date of receipt : 24 Februar-y 1989) (Date of acceptance : 09 August 1989) Abstract: A survey of rice-field weeds was carried out in the Districts of Ratnapura and ~urunegaladuring the 'Yala' and 'Maha' seasons of 1986. Two hundred and thirty four fields of the Ratnapura District and 196 fields of the Kurunegala District were sampled at a time when the rice was at heading to flowering and farmers had carried out weeding or herbicide applications for weed control. One hundred and forty seven species of weeds belonging to 95 genera and 37 plant families were recor- ded from the two districts, indicating a vcry rich diversity in thc weed-flora. Of thcse, 38 species occurred in less than 10% of the fields ;65 species in 10-20% of the fields and 44 species in 20% or more fields. By far the commonest and problematic wceds were monocotylcdons of the families Poaceae (Gramineae) and Cyperaceae. Tl11.e~grass spccies Echirrochloa crirs-galli (L.)Beauv., Echinochloa cotanurn (L.) Link. and Iscbat,~nnmrrrgosum Salisb. emerged as the most abundant species in both districts, both in tcrrns of frcqucncy of occurrence and levels of infestation. kiwzbri- stylis milinccu (L.)Vahl, C~~prrus.piL)susVahl and Cyperus iria L. of the Cyperaceae were also vcry common in both LJistricts. -

SAJID AQEEL AHMAD, MANSOOR HAMEED, TAHIRA NAWAZ AND AYESHA TARTEEL Department of Botany, University of Agriculture, Faisalabad, Pakistan 38040 *Corresponding author’s e-mail: [email protected] Abstract Two aquatic halophytic sedges, Schenoplectus juncoides (Roxb.) Palla and Fimbristylis dichotoma (L.) Vahl, were collected from salt-affected habitats and evaluated hydroponically for salt tolerance. Three salinity levels (0, 100, 200 mM NaCl) were maintained in half-strength Hoagland’s nutrient solution during the experiment. Although both species showed high degree of salt tolerance, they had varied mechanisms of salt tolerance. Fimbristylis dichotoma showed high uptake of Ca2+ and accumulation of organic osmotica to combat with high salinity, while S. juncoides relied on high uptake of K+ in addition to organic osmotica. The stem succulence in S. juncoides provided additional advantage to this species to survive under extreme saline regimes. It was concluded that both these species have considerably potential to rehabilitate of salt- affected wetlands. Introduction Agriculture, Faisalabad.

Cytological Studies in Cyperaceae with Special Reference to Its Taxonomy Ll
Cvtologia 43: 643-653, 1978 Cytological Studies in Cyperaceae with Special Reference to its Taxonomy ll S. P. Rath and S. N. Patnaik CytogeneticsLaboratory, P. G. Departmentof Botany,Utkal University, Bhubaneswar,India. 751004 ReceivedApril 25, 1977 During the recent years a few workers have reported chromosome numbers of various members of the family Cyperaceae from different regions of India. Notable among them are Sanyal (1972), Sanyal and Sharma (1972). Rath and Patnaik (1974a and 1974b), Nijalingappa (1975) and Mehra and Sachdev (1975). A survey of all these reports reveals that not only most of the genera are characterised by series of aneuploid numbers but there is great disparity in the findings of different workers in respect of chromosome numbers for the same species. Moreover certain genera have not been cytologically worked out. This necessitates further study in the family in a more broad based plan. As a continuation of our previous report (Rath and Patnaik 1974a) of chromo some numbers in 24 species of the family, meiotic studies of another 45 species are presented here in the light of which certain taxonomic problems are discussed. Materials and methods Plants were collected from various parts of the State of Orissa and fixings col lected in the field were generally worked out immediately as even 2-3 days of storing in the usual procedure of fixing in acetic-alcohol (1:3) and transfering to 70% ethyl alcohol induce excessive staining of the cytoplasm. Addition of chloro form to acetic acid and ethyl alcohol mixture though proved slightly better it did not very much improve the staining quality. -

Bryson1 and Richard Carter2 1USDA-ARS, Southern Weed Science Research Unit, Stoneville, MS 38776 2Department of Biology, Valdosta State University, Valdosta, GA 31698 Introduction Results Brown flatsedge (Cyperus fuscus L.) is a native to Europe, Field observations at the three sites in Arkansas and Mississippi, Asia, Indian subcontinent, and the Mediterranean Region of determined that brown flatsedge was highly dependent on persistent Northern Africa. It was first discovered in North America in moist soils or shallow standing water for establishment, growth, and 1877 and apparently was introduced around wharfs from seed production. Over a five-year period and under natural field contaminated ballast. Since that time, brown flatsedge has conditions, brown flatsedge plants germinated from late March and been discovered in Canada and U.S.A. In the U.S.A., it is early April until frost. Inflorescences were observed as early as found in Arkansas, California, Connecticut, Kansas, Maryland, May, and seed production continued until frost.
