Salix matsudana Koidz was exposed to different concentrations of Cd (0, 10, 50, and 100 µmol/L) to study the effects of Cd on mineral metabolism and antioxidant enzyme activities. The results showed that plant height and root length were inhibited by 50 and 100 µmol/L Cd, except the one under 10 µmol/L Cd treatment. The Cd content accumulated in different organs of S. matsudana, gradually increasing...
Hydraulic characteristics and contaminant removal effect in a vertical subsurface-flow constructed wetland were investigated by establishing a numerical model. The results demonstrated that retardation factor decreased with time while wetland substrate was gradually filled with the importation of contaminated water until reaching the saturation state. The flow velocity increased with time when the...
The effects of different NaCl concentrations (0.1, 0.2, and 0.4%) on plant growth, the enzymatic antioxidant system, lipid peroxidation, and cell damage were investigated in Salix matsudana Koidz to better understand the tolerant mechanism under NaCl stress. The results indicate that cell damage was induced in roots by NaCl stress as early as after just 1 h of exposure, which increased with increasing...
To understand the phytoremediation capability of Cd by Salix babylonica L. we studied Cd accumulation and translocation, antioxidant enzyme activities, lipid peroxidation, and soluble protein contents in S. babylonica exposed to 10, 50, and 100 μM Cd for 7, 14, 21, and 28 d. The results indicated that seedling growth was accelerated by 10 μM Cd, and significantly inhibited by 50 and 100 μM Cd. The...
An efficient and robust method for analyzing constituents of a well-known traditional Chinese medicine (TCM) formula SiWu decoction (SWD) contains AngelicaeSinensis Radix (ASR), Chuanxiong Rhizoma (CR), Paeoniae Radix Alba (PRA), and RehmanniaeRadix Praeparata (RRP) by ultra high-performance liquid chromatography (UHPLC)/time-of-flight mass spectrometry (TOF-MS) was established. The method efficiently...
