This study was conducted to determine the relationship in Hoagland’s hydroponic culture medium between fluoride at levels of 190, 380, 570, and 950 mg F/ L and the ability of different clones of basket willow (Salix viminalis L.: ‘Bjor’, ‘Jorr’, and ‘Tora’) to take up F. After 14 days of exposure to NaF in the medium, the roots and leaves of seedlings of these three varieties of basket willow w...

Changes in levels of abscisic acid (ABA) and cytokinin activity in the xylem sap of willow (Salix viminalis, L.) were followed throughout two growth cycles.Growth in spring was preceded by decreasing levels of ABA and an increase in cytokinin activity. The onset of dormancy was associated with low levels of cytokinins and high contents of ABA. A second peak of ABA was found in July which was no...

The protective antioxidative effect of the phenolic extract (PE) isolated from Salix viminalis pyrolysis derived bio-oil was shown in vitro on the Chinese hamster ovary (CHO) cells exposed to hydrogen peroxide (H2O2). Cells pretreated with 0.05 μg/ml PE after exposure to different concentrations of H2O2 (300-900 μM) showed up to 25 % higher viability than the unpretreated ones. The antioxidativ...

The present study was designed to investigate the antioxidant potential and oil composition of Callistemon viminalis leaves. GC-MS analysis of the n-hexane extract revealed the presence of 40 compounds. Leaves contained appreciable levels of total phenolic contents (0.27-0.85 GAE mg/g) and total flavonoid contents (2.25-7.96 CE mg/g). DPPH radical scavenging IC₅₀ and % inhibition of linoleic ac...
