The host range of the knapweed nematode, Subanguina picridis (Kirjanova) Brzeski, under controlled environmental conditions was extended to include, in addition to Russian knapweed, Acroptilon repens (L.) DC., plant species within the Centaureinae, and Carduinae subtribes of the Cynareae tribe of the Asteraceae family. Examination of host response to nematode infection revealed that Russian kna...

The knapweed nematode, Subanguina picridis, forms galls on the leaves, stems, and root collar of Russian knapweed, Acroptilon repens. After being revived from a dormant, cryptobiotic state, second-stage juveniles required at least 1 month in a free-living state before becoming infective. Galls were induced on relatively slow-growing host plants that retained their apical meristems at or near th...

The aim of this study is the evaluation effect Afghan talkhak (Acroptilon Repens) root aqueous extract on blood glucose level diabetic rats. Rats were randomly divided into 5 groups (1 Normal, 1 Diabetic and 3 groups). Experimental diabetes was induced by single-dose intraperitoneal (i.p.) injection streptozotocin (55 mg/kg) in extracts groups. 72 hour later, induction approved received Acropti...
