chromosome counting was performed in nine populations of achillea tenuifolia lam and eight populations of a. bieberestinii afan (asteraceae) collected from hamedan and kermanshah provinces in the west of iran. chromosome numbers in both species varied from 2n=2x=18 to 2n=4x=36. some populations of both species showed (2n=4x=36) chromosome number that is the first report as polyploidy levels. an...

The cytological features including chromosome numbers and detailed measurements of 46 populations ten Achillea species ( A. aleppica, bibersteinii, eriophora, filipendula, millefolium, nobilis, pachycephala, tenuifolia, vermicularis, wilhelmsii ) were reported from Iran. Sample plants seeds collected diff erent geographical regions Total length, long/ short arm ratio, centromere index, total fo...

The objective of this study was to evaluate the biological activities and chemical fingerprint profiles extracts obtained from twelve Achillea L. species (A. lycaonica, A. biebersteinii (syn: arabica), kotschyi subsp. kotschyi, schischkinii, millefolium millefolium, sintenisii, setacea, teretifolia, wilhelmsii santolinoides wilhelmsii), nobilis, goniocephala, spinulifolia). antioxidant, enzyme ...

There is substantial diversity in Achillea biebersteinii plants in Iran. It has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. Research improvement for medicinal plants depends on the available genetic diversity. The assessment of genetic variability could increase the information for breeding programs. ...
