“…In the study, the rice seedlings were grown in a Hewitt nutrient medium (which has greater concentrations of nutrients compared to the Kimura B solution) and was grown in temperatures of around 26 o C for around a month. As this study is similar to that done by Chauhan, et al (2017), it may be an indication that given a longer time period or stronger environmental conditions, sufficient growth would have occurred for more reliable analysis of the As content of the plant material. However, it cannot be said that the trends in the data would be similar to that of Chauhan, et al (2017) as there is no significant trend present in this data.…”

“…However, the sensitivity of the atomic absorption spectrometer had a minimum sensitivity to arsenic of 0.4mg/l, which all the measured values are below, it is therefore likely that the data is unreliable. In a similar study by Chauhan, et al (2017), who looked at the effects of different concentrations of Se (at similar levels to this study) on As toxicity (As at double the concentration in this study). They observed a significant difference in root and shoot lengths and biomass as well as reductions in As accumulation in both root and shoot material with increasing Se concentrations.…”

Phosphorus (P) and Selenium (Se) supplementation to rice plants grown in Arsenic (As) contaminated conditions as be found by many studies to reduce As uptake and benefit growth in such conditions, however there are some inconsistencies as to how effective these treatments are. This study investigates the effect of 0, 0.5, 1, 1.5 and double the recommended concentration of P and Se on the growth of rice seedlings both with and without the presence of As over a maximum 20 day period. Analysis of the growth data collected indicated that there is no significant difference in the leaf, maximum and minimum root lengths, leaf and root numbers or the As content of the plant material. This study finds that different concentrations of P and Se do not affect growth at early stages and do not affect As uptake.

“…These compounds not only act as efficient free radical scavengers but also inhibit the lipid peroxidation process and membrane stabilizers (Arora et al 2000;Michalak 2006;Verstraeten et al 2003). They also have marked ameliorative effects towards various abiotic stresses like heavy metals, chilling, osmotic stress and salinity (El-Tayeb et al 2006;El-Soud et al 2013;Li et al 2011;Singh et al 2013;Ozfidan-Konakci et al 2015;Chauhan et al 2017). Among the various class of plant phenolics, coumarin and its derivatives (Razavi 2011;Al-Amiery et al 2012;Saleh et al 2015), ferulic acid (Li et al 2013), ellagic acid (El-Soud et al 2013) etc.…”

The effect of rutin and gallic acid on growth, phytochemical and defense gene activation of rice ( L.) was investigated. The seeds of rice were primed with different concentrations of rutin and gallic acid (10-60 µg mL) to explicate the effect on germination on water agar plates. Further, to study the effect of most effective concentrations of gallic acid (60 µg mL) and rutin (50 µg mL), greenhouse pot experiment was set up to determine the changes in growth, antioxidant and defense parameters. The results revealed more pronounced effect of gallic acid on total chlorophyll and carotenoids as well as on total flavonoid content and free radical scavenging activities. Gene expression analysis of and genes involved in strengthening the plant defense further validated the results obtained from the biochemical analysis. Microscopic analysis also confirmed reduction in total reactive oxygen species, free radicals like HO and O by exogenous application of gallic acid and rutin. The data obtained thus suggest that both gallic acid and rutin can affect the growth and physiology of rice plants and therefore can be used to develop effective plant growth promoters and as substitute of biofertilizers for maximizing their use in field conditions.

“…In addition, it moves into human bodies through grain which is significantly important for the reduction of Se deficiency in humans [79]. As well, Se application in the As contaminated environment reduce As uptake and phyto-toxicity by modulation of phenolic compounds and increase biomass growth and nutritional quality of food crops [80,81].…”

19Arsenic (As) is a carcinogenic substance. It increased in crop grown in field soil from ground water 20 irrigation. Subsequently As transport into the human body through food chains. The reduction of 21 As transport in root, shoot and grain of pea genotypes is significantly important to protect human 22 health. This research is focused on the biomass growth and alleviation of As accumulation in root, 23 shoot and grain of pea genotypes in high As soil (30mgkg -1 ) amended with arbuscular mycorrhizal 24 fungi (AMF), biochar (BC) of rice husk and saw dust, selenium (Se), silica-gel (Si), and sulfur 25 (S). Shoot length, root, shoot and pod mass were generally higher in pea crops grown in soil 26 amended with AMF, Se, Si-gel and S. Rice husk and saw dust BC less consistently increased 27 some growth parameters, particularly in genotype BARI Motor 2. However, the BC's more often 28 reduced growth and pod mass. All treatments significantly reduced As concentration in tissues; As 29 in grains was reduced on average 60% by any of the soil amendments. AMF, Se and Si-gel all 30 were found more effective than BC for the reduction of As uptake in pea crops. As in grains was 31 reduced 77% by AMF, 71% by Se and 69% by Si-gel on average. As in root, shoot, and grain was AMF, Se, S, Si-gel and BC reduce arsenic uptake in plant biomass 32 also affected by variety; in control treatments, total As uptake in plants pot -1 of BARI Motor 1 and 33 3 was found 60 to 70% higher than BARI Motor 2. Comparing the variety and treatment with most 34 As in grains (BARI Motor 1 control, 0.35 mg As kg -1 ) and least As in grains (BARI motor 1, 2 & 35 3 with AMF with 0.07 mg As kg -1 ), the choice of variety and soil amendment could reduce human 36 intake of As through pea by 80%. It is recommended that choice of pea variety and soil amendment 37 with AMF and Se have great potential for improving the nutritional quality of pea grown in As 38 contaminated soil, as well as reducing As transfer to human bodies through food chains in pea 39 crops.40 41 45 major concern of ingested As is cancer, primarily of skin, bladder, and lung [1]. This metal moves 46 into the human body through the assimilation of food or water. Ground water is the main source 47 for the contamination of As in the soil. It is a global problem, including Bangladesh, Chile, China, 48 Vietnam, Taiwan, India, and the United States [2]. Consequently, As is the number one hazardous 49 substance according to the priority list of the Agency for Toxic Substances and Disease Registry 50 [3].51 Simultaneously, Field pea (Pisum sativum) is one of the delicious and nutritious pulse crop in 52 Bangladesh as well as throughout the world. It supplies high concentration of antioxidants, starch, 53 protein, fiber, vitamins, minerals and phytochemicals [4]. Fiber in seed coat and cotyledon of pea 54 improves gastrointestinal function. Pea protein, when hydrolyzed, may yield peptides with AMF, Se, S, Si-gel and BC reduce arsenic uptake in plant biomass 55 different bio-active compounds [5...
