Primary 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 کاملVascular 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 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...
متن کاملبررسی بیوسیستماتیکی جنس (cyperus l.(cyperaceae در شمال شرق ایران
جنس cyperus l. با 700 گونه در جهان، دومین جنس بزرگ تیره cyperaceae محسوب می شود. این تاکسون جهان شمول و مراکز تنوع آن در مناطق گرمسیری و نیمه گرمسیری جهان می باشد. براساس فلورا ایرانیکا این جنس 45 گونه دارد که از این میان 23 گونه از آن در ایران می باشد. به منظور برطرف کردن مشکلات تاکسونومیکی گونه های این جنس در شمال شرق کشور، مطالعات ریخت شناسی (تاکسونومی عددی)، تشریحی، گرده شناسی و مطالعه سطح ...
Análise Espacial da Distribuição de Aedes Aegypti (Diptera: Culicidade) em Diferentes Áreas da Cidade do Rio de Janeiro
This work aimed at assessing the spatial distribution of the dengue fever mosquito vector, Aedes aegypti and its association with Strategic Sites (SS). In each of three localities of Rio de Janeiro city, 80 traps were installed (40 for adult mosquitos and 40 for immatures) in randomly chosen households. Moreover, two further traps we installed close to each SS. These traps were localized with G...
