“…MDA is a marker for plant lipid peroxidation, which can reveal oxidative damage and cell membrane integrity [17]. Heavy metal stress can stimulate plants to generate more reactive oxygen species (ROS), which can bind with cell organelles, cause lipid peroxidation, damage membranes, and disturb enzyme activation, reducing cell performance and viability [17,39,40]. In this study, MDA content was enhanced with the proliferation of Cd stress (Figure 2).…”

“…The higher MDA content also indicates the destruction of redox balance under higher Cd stress [11,17,30]. Comparable results were reported in many plant species, such as Sassafras seedlings, Amaranthus tricolor, duckweed, Ceratophyllum demersum, and Vigna radiata, which had higher MDA content under increasing Cd stress [11,17,39,41,42]. Therefore, other abiotic stresses also caused a similar increase in MDA content in plants [43,44].…”

“…These results suggested that three antioxidant enzymes were working concurrently to reduce reactive oxygen species from different plant parts of S. portulacastrum [11,39]. These findings also suggested that POD was likely to be the main antioxidant enzyme activity for protection from the reactive oxygen species [11].…”

“…Similar findings were observed in many different plant species, such as Acanthus ilicifolius, Sassafras seedlings, Ceratophyllum demersum, etc. [11,17,39]. The activity of different antioxidant enzymes did not have similar concentration patterns with increasing Cd stress.…”

This study aimed to investigate the physiological and cellular mechanisms of Sesuvium portulacastrum under heavy metal stress to evaluate possible tolerance and adaptation mechanisms in a metal-polluted environment. The physiological and cellular ultrastructural responses of S. portulacastrum were studied hydroponically under exposure to a range of cadmium (Cd) concentrations (50 µM to 600 µM) for 28 days. The activity of antioxidant enzymes like catalase (CAT), superoxide dismutase (SOD), and peroxidase (POD), changes in chlorophyll, and cellular ultrastructural content were examined. There was no significant difference in chlorophyll content in the leaf under the stress of 300 μM, but 400 μM and 600 μM Cd stress showed significantly decreased chlorophyll content. The SOD activity indicates an increase under the Cd stress of 100 μM for leaves, 300 μM for stems, and 50 μM for roots; after that, the SOD activity gradually decreased with increasing Cd concentrations. But POD activity was considerably increased with increasing Cd stress. CAT activity showed a gradual increase in concentrations until 300 μM of Cd stress and then decreased sharply in roots, stems, and leaf tissues. Cd stress had a considerable impact on the structure of the roots, stems, and leaves cells, such as distorted and thinner cell walls and the deformation of chloroplasts, mitochondria, and other organelles. Therefore, the increased number of nucleolus in the cell nucleus suggests that cells may be able to maintain their protein synthesis in a stressful environment. This study concludes that SOD is the dominant antioxidant enzyme activity during low Cd toxicity (<100 μM), while POD is the dominant enzyme activity during higher Cd toxicity (>100 μM).

“…The undersized effects were observed on all plant parts (Table 3). Since the source of the problem was in the growing substrate; then, the first suffering organ was the roots, as indicated by smaller root biomass and shorter roots (Liu et al 2021). The uptake of water and nutrients by affected plants becomes restricted and collectively halts the development of aerial organs, including leaf enlargement (Bellache et al 2022).…”

Red amaranth (Amaranthus cruentus L.) is a fast-growing and nutritious leafy vegetable. The seed population density needs to be known appropriately to obtain the optimal yield of marketable sizes plants. The residue of black soldier fly (BSF) larvae culture has been recognized as a potential source of nutrients for cultivating red spinach plants. This study was designed to search for the best combination of plant population density and BSF concentration to obtain the optimal marketable yield of the red amaranth plant. In addition, an accurate leaf area estimation of the red amaranth plant was also developed using leaf dimensions as a predictor with several regression models. Two experiments were conducted. Firstly, the BSF residue was applied at a high rate (up to 50%) using a floating culture system. Application of the residue at the rate of 30% and higher significantly inhibited the growth of the red amaranth. Secondly, the application rate was reduced to 10% and 20%, and the experiment was conducted using the conventional cultivation system. Results indicated that the optimum application rate of the BSF residue was 10% for enhancing growth. Application of seed density at 30 mg/dm2 produced an optimum marketable yield of the red amaranth since a higher population density causes plant-plant competition. Thus, creating high size variability within the population or reducing the average size of the harvested plants. Lastly, the leaf area of red amaranth can be accurately estimated using the leaf length x width (LW) as a predictor using the zero-intercept linear regression model.
