Worldwide Distribution of Purple and Yellow Nutsedge (Cyperus rotundusandC. esculentus)

Abstract: The family Cyperaceae includes approximately 3000 species, of which about 220 species are identified as weeds (Table 1). Nearly 42% of these weeds are in the genusCyperus. An additional 43% are in three other genera,Eleocharis,Scirpus, andFimbristylis. The remaining 15% are found in six other genera,Scleria,Kyllinga,Rhynchospora,Bulbostylis,Fuira, andDichromena. Purple nutsedge (Cyperus rotundusL. # CYPRO) was identified as the world's worst weed based on the number of countries where it was reported as a seri… Show more

“…A agressividade e ampla distribuição nas infestações de C. rotundus podem ser atribuídas à propagação vegetativa por rizomas e tubérculos, fixação do carbono pela via fotossintética C4 e tolerância a solos úmidos e temperaturas elevadas (Bendixen & Nandihalli 1987). Compostos aleloqúimicos presentes nos tubérculos aumentam o potencial competitivo de C. rotundus, inibindo ou reduzindo a germinação de sementes de outras espécies (Singh et al 2009).…”
