the mineral contents of centaura leave and seeds were determined by inductively coupled plasma-atomic emission spectroscopy (icp-aes). macro element concentrations (p, k, ca, mg and s) of samples were found at high levels. k was established at high level in both leave and seed samples of centaurea. while k contents of leaves changes between 7254.10 mg/kg (centaurea lycaonica) and 26396.36 mg/kg...

The aim of this research is an improvement of plant seedling recognition by two new approaches of shape feature generation based on plant silhouettes. Experiments show that the proposed feature sets possess value in plant recognition when compared with other feature sets. Both methods approximate a distance distribution of an object, either by resampling or by approximation of the distribution ...

In this study, antiproliferative activity of methanol extract of Centaura carduiformis DC. subsp. carduiformis var. carduiformis DC (CC) was examined against Vero, HeLa and C6 cell lines in 1000 and 500 mg/mL concentrations using the BrdU ELISA assay. The CC root (CCR) has the most effective antiproliferative activity. The root extract was fractionated using various solvent and determined antip...

The knowledge of rangeland vegetation types and factors influencing on their establishment and stability is essential for sustainable management and regeneration of rangeland areas. With this aim, Gonbad watershed, due to different vegetation types, environmental conditions and grazing managements was studied. The watershed was stratified to homogenous units based on morphology of vegetation ty...

نوع مدیریت و نیز شرایط محیطی و خاکی حاکم بر اکوسیستم های مرتعی باعث استقرار تیپ های مختلف گیاهی می شود که خود اثرات متفاوتی بر کیفیت خاک اعمال می کند. در این پژوهش تاثیرپوشش های گیاهی مختلف بر بخش¬های کربن آلی خاک در حوضه مطالعاتی زوجی گنبد در شهر همدان مورد مطالعه قرار گرفت. کل حوضه به واحدهای کاری همگونی از نظر ریخت پوشش گیاهی و ویژگی های محیطی تفکیک شد و در هر ریخت، 3 الی 4 قاب (1*1 متر مربع...
