“…Thus, the seed germination of plant depends on the integrity of structure and stability of function in the cell membrane. It has been reported that the abiotic stress can cause the excess accumulation of free radicals in plants [27,28]. The excess free radicals oxidize the unsaturated fatty acids in the membrane lipid of cell [29], leading to the peroxidation of cell membrane lipid [30,31].…”

Cadmium (Cd) pollution and acid rain are the main environmental issues, and they often occur in the same agricultural region. Nevertheless, up to now, little information on the combined pollution of Cd(2+) and acid rain action on crops were presented. Here, we investigated the combined effect of Cd(2+) and acid rain on the seed germination of soybean. The results indicated that the single treatment with the low level of Cd(2+) (0.18, 1.0, 3.0 mg L(-1)) or acid rain (pH ≥3.0) could not affect the seed germination of soybean, which was resulted in the increased activities of peroxidase and catalase. The single treatment with the high concentration of Cd(2+) (>6 mg L(-1)) or acid rain at pH 2.5 decreased the activities of peroxidase and catalase, damaged the cell membrane and then decreased the seed germination of soybean. Meanwhile, the same toxic effect was observed in the combined treatment with Cd(2+) and acid rain, and the combined treatment had more toxic effect than the single treatment with Cd(2+) or acid rain. Thus, the combined pollution of Cd(2+) and acid rain had more potential threat to the seed germination of soybean than the single pollution of Cd(2+) or acid rain.

“…Plants have evolved different phytochemicals and enzymes as antioxidant defense to maintain growth and metabolism (Pandhair & Sekhon, 2006). Concern about improving health, involving agricultural products with potential benefits, has enhanced research on antioxidants (Moore, Hao, Zhou, Luther, & Costa, 2005).…”

“…According to Pandhair and Sekhon (2006), plants exposed to biotic and abiotic stresses generate more reactive oxygen species (ROS) than their capacity to scavenge them. This is also true in humans and researchers have demonstrated that free radical such as ROS have been implicated in degenerative or pathological process such as aging (Ames et al 1993;Harman 1995), cancer, heart diseases and Alzheimer's disease (Ames 1983;Gey 1990).…”

Analyses on biological activities of Gnetum gnemon were done to determine the total phenolic and antioxidants of the plant. Four parts of G. gnemon were used in this study, which were leaf, bark, twig, and seeds of the plant. All parts were extracted in methanol, ethanol, hexane, chloroform and hot water using reflux. The total phenolic content of the plant extracts were determined by using Folin-Ciocalteu method. The results demonstrated that the bark from hot water extract showed the highest total phenolic at 10.71±0.01 mg GAE/ FDW, while the lowest was chloroform extract of seed at 2.15±0.01 mg GAE/ FDW. The antioxidant activity of the plant extracts were determined by using DPPH and FRAP assays, respectively. The DPPH results showed that all plant extracts demonstrated weak free radical scavenging activity tested at the final concentration of 300 μg/ml. In contrast, the methanolic twig extract showed strong reducing power activity (FRAP) at 83.55±1.05%, while the hot water seed extract showed the least activity at 41.86±4.22% tested at the final concentration of 300 μg/ml. However, there were no correlation between total phenolics and both antioxidant assays tested.
