“…It demanded even more time for the same reason as seedling growth at a constant temperature of 10 • C. Even though a nearly similar growth pattern to that of the 5 • C was presented at 25 • C and 30 • C, nevertheless, it was far faster (Figure 3). This is due to the inverse influence of the high temperature levels on enzymes functions, protein synthesis, and increased biochemical energy content and ROS production, not because of the temperature accumulation [11,32,81,87,88]. At 25 and 30 • C, early seedlings exhibited a growth pattern that resembled one another to a small degree; they grew rapidly, then slowed down (Figure 3).…”

Seed germination and seedling growth are highly sensitive to deficit moisture and temperature stress. This study was designed to investigate barley (Hordeum vulgare L.) seeds’ germination and seedling growth under conditions of abiotic stresses. Constant temperature levels of 5, 10, 15, 20, 25, 30, and 35 °C were used for the germination test. Drought and waterlogging stresses using 30 different water levels were examined using two methods: either based at 1 milliliter intervals or, on the other hand, as percentages of thousand kernel weight (TKW). Seedling density in a petri dish and antifungal application techniques were also investigated. Temperature significantly impacted germination time and seedling development with an ideal range of 15–20 °C, with a more comprehensive range to 10 °C. Higher temperatures reversely affected germination percentage, and the lower ones affected the germination and seedling growth rate. Germination commenced at 130% water of the TKW, and the ideal water range for seedling development was greater and more extensive than the range for germination, which means there is a difference between the starting point for germination and the seedling development. Seed size define germination water requirements and provides an objective and more precise basis suggesting an optimal range supply of 720% and 1080% of TKW for barley seedling development. A total of 10 seeds per 9 cm petri dish may be preferable over greater densities. The techniques of priming seeds with an antifungal solution (Bordóilé or Hypo) or antifungal application at even 5 ppm in the media significantly prevented fungal growth. This study is novel regarding the levels and types of abiotic stresses, the crop, the experimental and measurement techniques, and in comparison to the previous studies.

“…The reduction in above-ground biomass after stress is the most intuitive manifestation. Turner and Rust ( 1971b ) and Basit et al ( 2022b ) found that in hydroponics treated with 0.5 mg L −1 · chromium and soil cultures treated with 10 mg·L −1 chromium could significantly reduce the dry matter content in the aerial parts of soybeans (Glycine max). Turner and Rust ( 1971b ) found similar results in subsequent studies with rice ( Salvinia minima ) and other plants (Prado et al, 2010 ).…”

In recent years, heavy metals-induced soil pollution has increased due to the widespread usage of chromium (Cr) in chemical industries. The release of Cr into the environment has reached its peak causing hazardous environmental pollution. Heavy metal-induced soil pollution is one of the most important abiotic stress affecting the dynamic stages of plant growth and development. In severe cases, it can kill the plants and their derivatives and thereby pose a potential threat to human food safety. The chromium ion effect on plants varies and depends upon its severity range. It mainly impacts the numerous regular activities of the plant's life cycle, by hindering the germination of plant seeds, inhibiting the growth of hypocotyl and epicotyl parts of the plants, as well as damaging the chloroplast cell structures. In this review article, we tried to summarize the possible effects of chromium-induced stress on plant growth, developmental physiology, biochemistry, and molecular regulation and provided the important theoretical basis for selecting remedial plants in chromium-induced contaminated soils, breeding of low toxicity tolerant varieties, and analyzing the mechanism of plant resistance mechanisms in response to heavy metal stress.

“…Rice is a major food crop in Indonesia, where its consumption increases every year following population growth, impacting the availability that should be maintained. However, several problems in cultivation, including environmental degradation and land stress, retard production (Basit et al 2022). Lately, there has been an increase in toxic and hazardous substances caused by heavy metal pollution in rice fields.…”

Abstract. Ubaidillah M, Thamrin N, Cahyani FI, Fitriyah D. 2023. Bioremediation potential of rhizosphere bacterial consortium in lead (Pb) contaminated rice plants. Biodiversitas 24: 4566-4571. Lead (Pb) is one of the toxic heavy metals detected in various chemical fertilizers and pesticides used in Indonesia. These chemicals can increase plant lead (Pb) accumulation and affect other organisms through its circulation with food chain. Excess amounts of Pb in soil may be remediated using different approaches such as bioremediation. Rhizosphere bacteria can be used as bioremediation agents to reduce Pb accumulation in plants and also increase plant growth. Actinomycetes, Azotobacter sp., Azospirillum sp., Rhizobium sp., Pseudomonas sp., Lactobacillus sp., Bacillus sp., and Streptomyces sp. are some of the several bacteria that can reduce lead (Pb) accumulation in plants by the ability to sequester Pb, change its oxidation state, or enable Pb to precipitate. This research was conducted to determine the ability of the rhizosphere bacterial consortium to prevent lead (Pb) accumulation in rice plants. This study confirmed that the application of rhizosphere bacterial consortium to rice plants contaminated with lead (Pb) can reduce the plant's lead (Pb) content by up to 45%. The use of a bacterial consortium did not significantly affect the growth parameters of the plant but increased root length by 41%, fresh weight by 32%, dry weight by 26%, and chlorophyll content by 25%, in rice plants contaminated with Pb.
