“…The inhibitory effect of metals on cell expansion and division might be due to inhibition of growth promoters primarily through blocking enzyme activation and lowering or direct blocking of cell division by intrusive with the cell membrane integrity [13]. These results of present study agreed with findings on the Cluster Bean [14] wheat [10] the Psyllium and on Mung bean .…”

Plants often experience abiotic stress like salinity, drought, high or low temperature, flooding, metal toxicity, ozone, UV-radiations, herbicides, etc., which pose serious threat to the crop production. Germination studies showed that heavy metal exposure caused a decrease in seed germination and at higher doses the seeds failed to germinate. This was confirmed by root length and shoot length. Ascorbic acid content was found to be decreased in all the treatment groups. However the phenol content was found to be decreased significantly with increasing concentrations of metals. There was considerable increase in phenolic content in water logging conditions. Metal treatment also led to an increase in catalase activity, thus showing that abiotic stress induced oxidative stress in the plants and antioxidants tend to neutralize this stress.

“…For example, failure to produce seeds in soybean treated with nZnO (500 mg kg −1 ) was attributed to the significant accumulation of Zn (Yoon et al 2013). According to Munzuroglu and Gur (2000), Zn decreases pollen grain germination and pollen tube growth.…”

A soil microcosm study was performed to examine the impacts of cerium oxide nanoparticles (nCeO2) on the physiology, productivity, and macromolecular composition of barley (Hordeum vulgare L.). The plants were cultivated in soil treated with nCeO2 at 0, 125, 250, and 500 mg kg(-1) (control, nCeO2-L, nCeO2-M, and nCeO2-H, respectively). Accumulation of Ce in leaves/grains and its effects on plant stress and nutrient loading were analyzed. The data revealed that nCeO2-H promoted plant development resulting in 331 % increase in shoot biomass compared with the control. nCeO2 treatment modified the stress levels in leaves without apparent signs of toxicity. However, plants exposed to nCeO2-H treatment did not form grains. Compared with control, nCeO2-M enhanced grain Ce accumulation by as much as 294 % which was accompanied by remarkable increases in P, K, Ca, Mg, S, Fe, Zn, Cu, and Al. Likewise, nCeO2-M enhanced the methionine, aspartic acid, threonine, tyrosine, arginine, and linolenic acid contents in the grains by up to 617, 31, 58, 141, 378, and 2.47 % respectively, compared with the rest of the treatments. The findings illustrate the beneficial and harmful effects of nanoceria in barley.

Aims:To determine the physiological and morphological responses of Amaranthus hybridus leaf area, shoot height, stem girth, leaf number, petiole length, fresh weight (FW) and dry weight (DW) of leaf, shoot and root, relative growth rate (RGR) and chlorophyll (chl.) content to simulated nitric and sulphuric acid rain. Place and Duration of Study: Methodology: Thirty five poly bags were used. Simulated nitric and sulphuric acid rain (SNAR and SSAR) of pH 2.0, 3.0, 4.0 and a control pH of 6.0 were separately prepared and sprayed every two days. The research was carried out in a greenhouse under controlled conditions. Results: Results showed highest decreases at pH 2.0 and lowest decreases at pH 4.0 in all the physiological parameters studied. Highest decreases are depicted by lowest measured values while lowest decreases by highest values in all measured parameters as affected by SNAR and Mofunanya and Soonen; BJAST, 21(4): 1-12, 2017; Article no.BJAST.31863 2 SSAR. Acid rain treated plants showed necrosis, chlorosis and leaf deformation. Chlorophyll a, b and total chlorophyll of acid rains treated plants revealed a trend of decrease in content with increasing period of development. Mean values for leaf area response to simulated HNO 3 and H 2 SO 4 acid rains of pH 2.0, pH 3.0 and pH 4.0 at 4 weeks period of development were 14.60±0.33 d , 17.50±0.47 d , 18.80±0.11 d and 14.94±0.23 d 17.70±0.20 d , 17.92±0.28 d as against control value of 22.62±0.26 d cm 2 . Mean values for shoot height response to acid rains had values of 16.48±0.59 d , 19.65±0.66 d , 20.46±0.88 d , 15.82±0.59 d and 18.27±0.12 d , 19.74±0.17 d and 24.48±0.23 d cm. Mean values for chl. a, b and total chl. at 28 days for SNAR and SSAR pH 2.0 and pH 6.0 were 18.9±0.12, 23.4±0.04 mg g -1 FW and 42.3, 20.0±0.3, 23.6±0.3 mg g -1 FW and 43.8 and 58.2 0.3, 71.2 0.3 mg g -1 FW and 129.4 respectively. Original Research Article Conclusion:Physiological and morphological parameters studied responded negatively to simulated nitric acid (HNO 3 ) and sulphuric acid (H 2 SO 4 ) rain with significant decrease at all acidity levels with respect to the control.
