[Uptake and Accumulation of Cadmium and Zinc by Two Energy Grasses: A Field Experiment].

The remediation potential of large biomass energy grasses in cadmium-contaminated soil remains ambiguous. A field experiment was carried out in a cadmium-contaminated farmland using two energy grasses and two control plants. The two energy grasses were hybrid pennisetum (×, PAP) and purple elephant grass ( 'Purple', PPP), and the two control plants were var.

[Chemical composition analysis of essential oil and allelopathic effects of -terpineol].

We extracted essential oil by steam distillation and analyzed its chemical components by GC-MS. The inhibitory effects of -terpineol, a component in essential oil, were tested in Petri dishes on the germination and growth of . The allelopathic effects of -terpineol on were examined with a pot experiment by measuring germination rate and biomass.

[Impacts of salt stress on the growth and physiological characteristics of Panicum virgatum seedlings].

An experiment was conducted in an artificial climate chamber to study the growth and physiological characteristics of switchgrass (Panicum virgatum) seedlings exposed to 0, 50, 100, 150, and 200 mmol x L(-1) of NaCl solutions. With the increasing concentration of the NaCl, the seedling growth was obviously inhibited. The plant height decreased, leaves became smaller, photosynthetic leaf area and net photosynthetic rate reduced, and dry matter accumulation decreased significantly, presenting the general traits of glycophyte.
