Karyotype study was performed across 7 populations of 4 Rubus species growing in Iran. The results showed that the chromosome numbers of R. sanctus (2n=2x=14) diploid, R. caesius, and R. discolor were (2n=4x=28) tetraploids, R. persicus (2n=8x=56) octoploid. The chromosome numbers of R. discolor, and R. persicus were reported here for the first time. Karyotypic formula also varied between the s...

The optical properties of leaves from five species, Norway maple (Acer platanoides L.), cotoneaster (Cotoneaster alaunica Golite), hazel (Corylus avellana L.), Siberian dogwood (Cornus alba L.), and Virginia creeper (Parthenocissus quinquefolia (L.) Planch.), differing in pigment composition and at different stages of ontogenesis, were studied. Anthocyanin absorption maxima in vivo, as estimate...

There are many plants in Mexico with medicinal properties, some of them used in alternative medicine to treat cancer, such is the case of Rhoeo discolor L. Hér Hance (Commelinaceae family); however, there are not scientific reports that validate their antitumoral property. The present study shows the protective effects of the Rhoeo discolor aqueous crude extract (ACE) against rat liver cancer u...

Accepted 25 January 2001 Copyright © EEF ISSN 1399-1183 Marked variations in flowering frequency, and irregular patterns of appearance above ground between years, were observed in many perennial herbs, among them various species of terrestrial orchids, such as Dactylorhiza sambucina (L.), Dactylorhiza incarnata (Druce), Orchis mascula (L.) and Listera ovata (L.) R. Brown (Tamm 1956, 1972), Spir...

Background & Aim: The manna of Cotoneaster nummularia (purgative manna) has been traditionally used in the Persian medicine for the treatment of neonatal jaundice. The effect of Cotoneaster manna on neonatal jaundice was investigated with systematic review and meta-analysis. Experimental: This study intended to explore the clinical trial...
