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...

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...

Isolation 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...

Antidiabetic activity of methanol extract of rhizomes of Cyperus tegetum Roxb. (Cyperaceae).

construction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers

the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
