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 کاملTAXONOMIC REVISION OF THE CYPERUS SUBGENUS CYPERUS IN IRAN
The genus Cyperus belongs to tribe Cypereae, subfamily Cyperoideae and family Cyperaceae that is the largest genus in this family after Carex. The classification of genus Cyperus is still unsettled because of morphological variations and therefore, makes determination of subgenera boundaries and species difficult. In Flora Iranica (KUKKONEN 1998) this genus was divided to six subgenera. In this...
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 کاملLEAF AND STEM ANATOMY OF THE CYPERUS SUBGENUS CYPERUS IN IRAN
The genus Cyperus with five subgenus and 29 species, is the second largest genus of Cyperaceae family in flora of Iran. In this research, stem and leaf anatomy of 10 species belonging to subgenus Cyperus is investigated. The stems in transverse section of all examined species were triangular except for C. bulbosus which was subterete to polygonal. The ground tissue was spongy with numerous and ...
