Vascular architecture of the monocot Cyperus involucratus Rottb. (Cyperaceae)
The arrangement of vascular bundles in the stems of monocots has been described repeatedly as "scattered." But to the trained eye it is clearly ordered as verified by the use of the R index of Clark and Evans. The arrangement of bundles in leaves and sclerenchyma bundles in stems are also ordered. An equation was developed for the probability distribution frequencies (pdf) for leaf intervein di...
متن کاملPhytoremediation Potentiality of Cyperus Articulatus L
The phytoremediation potentiality of Cyperus articulatus naturally growing in industrial wastewater was tested. Nine heavy metals were selected for this purpose; As, Cd, Cr, Cu, Fe, Hg, Mn, Ni and Pb. Metal concentrations were measured using the atomic absorption. The accumulation rates of the studied heavy metals showed considerable variations in the accumulation abilities according to the pla...
متن کاملPrimary and secondary development of Cyperus giganteus Vahl rhizome (Cyperaceae)
(Primary and secondary development of Cyperus giganteus Vahl rhizome (Cyperaceae)). In Cyperus giganteus, like in other Monocotyledoneae, the protoderm, procambium, fundamental meristem and primary thickening meristem (PTM) are differentiated from the rhizome promeristem. The PTM produces the inner cortical parenchyma, endodermis, pericycle and amphivasal vascular bundles, which are formed by t...
متن کاملAnti-Onchocerca activity and phytochemical analysis of an essential oil from Cyperus articulatus L
BACKGROUND The lack of a safe and effective adult worm drug and the emergence of resistant animal parasite strains to the only recommended drug, the microfilaricide, ivermectin put many at risk of the devastating effects of the onchocerciasis. The present study was undertaken to investigate the acclaimed anti-Onchocerca activity of the roots/rhizomes of Cyperus articulatus in the traditional tr...
متن کاملIsolation of nuclear microsatellite markers for Cyperus fuscus (Cyperaceae)1
PREMISE OF THE STUDY Microsatellite markers were characterized in the extremely specialized ephemeral wetland plant species Cyperus fuscus (Cyperaceae). The markers will be used for studying population genetics in natural vs. anthropogenic habitats, on a European scale, and the role of the soil seed bank in the life cycle of this ephemeral species. METHODS AND RESULTS Twenty-one microsatellit...
