“…The total chlorophyll content of A. caroliniana was 351.9 μg/g FW on day 3 and 324.3 μg/g FW on day 15. The amounts of chlorophyll a and b for A. filiculoides in the control medium were about 9 and 4 mg/g FW, respectively, whereas the total amount of chlorophyll was approximately 14 mg/g FW at the end of 7 days [31]. It was reported that the amounts of chlorophyll in the control medium of A. pinnata plant were about 6 and 7 mg/g FW on the 6 th and 12 th days, respectively [32].…”

This study aimed to evaluate the growth performance, pigment content changes, essential amino acids (EAAs), fatty acids (FAs), and proximate composition of Azolla pinnata and Azolla caroliniana grown in a greenhouse. Plants were grown in nitrogen-free Hoagland's solution at 28±2°C/21±2°C, day/night temperature and 60-70% humidity and examined on the 3 rd , 5 th , 10 th and 15 th days. The mean percentage of plant growth and relative growth rate for A. pinnata were 119% and 0.148 gg-1 day-1 , respectively, while for A. caroliniana these values were 94% and 0.120 gg-1 day-1 , respectively. Compared to day 3, the amount of total chlorophyll obtained on day 15 decreased significantly (p<0.05) for A. pinnata while the total phenolic and flavonoid contents increased significantly (p<0.05) from the 3 rd to the 15 th day. However, the total phenolic and flavonoid contents did not differ (p>0.0.5) in A. caroliniana. The crude protein, lipid, cellulose, ash values and the amounts of EAAs were higher in A. pinnata than A. caroliniana. Palmitic acid, oleic acid, and lignoceric acid were found to be predominant in A. pinnata and A. caroliniana. From the plant growth and pigment contents, we concluded that A. pinnata grew faster than A. caroliniana and its photosynthetic efficiency was more effective.

“…Moreover, exogenous NO increased Cd-decreased activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) in peanuts. In addition, the oxidative stress caused by NaCl in Azolla caroliniana is mitigated by nitrate (Mostafa & Tammam 2012). Arginine increased the activity of SOD, APX, and glutathione reductase (GR) and decreased the content of H 2 O 2 and MDA in tomato plants.…”

The research aimed to verify the important physiological effect of nitrogen (N) on plants exposed to cadmium (Cd). The poplar plants were grown in a Hoagland nutrient solution and treated with extra N, Cd, and N + Cd. After treatment, plant growth and chlorophyll content were recorded. The oxidative stress, the activity of antioxidant enzymes, and the expression of related genes were also examined. The results indicated the plants treated with sole Cd presented obvious toxicity symptoms, i.e. growth inhibition, reactive oxygen species accumulation, and chlorophyll content decrement. However, when N was added to the plants under Cd stress, plant growth was enhanced, chlorophyll synthesis was promoted, and the oxidative stress was alleviated. Further, the expression of antioxidant enzymes genes was upregulated by N. The results indicated that N partially reversed the toxic effect of Cd on poplar plants, which can provide new methodology to enhance the phytoremediation technology for heavy metal pollution soil.

“…Most of the angiospermic plants, particularly the crop species, have been the test sample to elucidate the pathways of antioxidation under various abiotic stresses. However, some non-angiospermic plants, particularly those of fern, are reported with their in-built tolerance to accommodate ROS (Mostafa & Tammam 2012;Satapathy et al 2012). Chinese brake fern is a citing example for hyperaccumulation of heavy metals and its tolerance to ROS has already been demonstrated (Xie et al 2009).…”

Salvinia natans L. response to hydrogen peroxide (H 2 O 2 ) induced oxidative stress through physiological activities was evaluated. The plants were incubated with varying concentrations (0, 50, 100 µM) of H 2 O 2 and 100 µM of H 2 O 2 supplemented with 1 mM putrescine (Put) in hydroponic culture. This is observed with the decline in proline content and its biosynthetic enzymes viz. γ-glutamyl kinase and γ-glutamyl phosphate reductase activity. Protein carbamylated derivative by protein oxidation was another trait for oxidative damages by H 2 O 2 . The antioxidative enzymes like guaiacol peroxidase (GPX), glutathione reductase (GR), and catalase (CAT) recorded to express through in-gel staining with the H 2 O 2 exposure. On nuclear level, plants were sensitive to H 2 O 2 where the DNA disintegration was studied with comet assay and maximum comet tail observed at 100 µM H 2 O 2 treatment. Application of Put reduced the generation of protein oxidation and comet tail length as well as moderated the enzyme activity as revealed through in-gel staining.
