The indiscriminate use of wireless technologies, particularly of cell phones, has increased the health risks among living organisms including plants. We investigated the impact of cell phone electromagentic fi eld (EMF) radiations (power density, 8.55 μW cm-2) on germination, early growth, proteins and carbohydrate contents, and activities of some enzymes in Vigna radiata. Cell phone EMF radiations signifi cantly reduced the seedling length and dry weight of V. radiata after exposure for 0.5, 1, 2, and 4 h. Furthermore, the contents of proteins and carbohydrates were reduced in EMF-exposed plants. However, the activities of proteases, α-amylases, β-amylases, polyphenol oxidases, and peroxidases were enhanced in EMF-exposed radicles indicating their role in providing protection against EMF-induced stress. The study concludes that cell phone EMFs impair early growth of V. radiata seedlings by inducing biochemical changes.

Currently, a real challenge for the workers in the agricultural research field is to stop or reduce the use of expensive agrochemicals/ chemical fertilizers which are hazardous to the environment as well as human health. Present study was aimed to improve the growth and obtain optimum yield of Vigna crop with eco-friendly, non-toxic way and to reduce the use of agrochemical/chemical fertilizer application in agricultural activities. A pot experiment was conducted to study the effect of chemical fertilizer (DAP) and biofertilizer ( Rhizobium strain) separately and in combination on seed germination and seedling growth (at 30 days) based on morphological parameters such as seedling length (cm), fresh weight (g), dry weight (g) and leaf area (cm)2 of Vigna radiata (L.) Wilczek. After one month (30 Days) observations, it was found that seedling length, fresh and dry weights and leaf area were maximum in T4 and minimum in T15, T7 and T8 favored improved seedling length and leaf area whereas T7, T8, and T9 favored improved fresh and dry weights as compared to control.

Leucaena leucocephala is a species that occurs in semi-arid regions capable of developing physiological and biochemical strategies under adverse environmental situations, such as saline soils and water deficiency. Even so, there are still losses in germination and initial development of plants, mainly due to abiotic stress effects, making it necessary to implement alternatives which are able to diminish the impact on the seeds with the use of potassium nitrate. The objective of this work was to evaluate the physiological quality in L. leucocephala seeds conditioned in potassium nitrate solution and subjected to saline and water stresses. After scarification, the unconditioned leucine seeds were separated and identified, and the conditioners were immersed in the 1.0 Mmol/L solution of potassium nitrate for 24 hours. The treatments were NaCl: 0; 30; 60; 90; 120 and 150 Mmol/L and the water potential: 0, 0; -0.2; -0.4; -0.6, and -0.8 MPa. The seeds were distributed over two Germitest® sheets, moistened with distilled water 2.5 times the dry weight and incubated in a B.O.D. at 25°C for 10 days. Then, the germination speed index, seedling length and seedling mass were measured for the normal seedlings. Eleven treatments with four replicates of 50 seeds were used. The design was completely randomized, and the statistical analyzes were performed in SAS. The use of potassium nitrate (KNO3) contributed to maintaining the physiological quality of L. leucochephala seeds under conditions of saline stress and water restriction.

An experiment was conducted to enhance the turnip seed performance under salinity stress conditions. The impact of priming with an optimized dosage (5 g/l) of KCl and NaCl had been evaluated for enhancing seedling vigor and salt stress tolerance in seedlings of the turnip. Seeds prepared with (5 g/l) of KCl and NaCl solutions were examined at different salinity levels (0, 50, 100, 150, 200)mM of NaCl concerning the early growth stage. The data were analyzed using SPSS windows version 23 (one way ANOVA p ≤ 0.05) to determine the significant difference between treatments and followed Duncan test, p 0.05 for means comparison. The results have shown that priming with KCl and NaCl were effective in reducing the adverse effects of salinity. A significant (P 0.05) increase in germination percentage, seed vigor, hypocotyl and radicle length, salt tolerance, and dry weight of the seedlings of seed that priming with (5 g/l) of KCl and NaCl compared to nonprimed seeds was recorded. On the other hand, In this experiment, it was concluded that seed priming with KCl and NaCl had been discovered to be better treatment, especially in the high concentration of salts as compared to non-primed seeds in case of turnip for rising the seeds vigor and seedling growth under salt-stressed conditions.

The advancement of a country depends upon its industrialization. Of all industrial sectors, the food processing units have highest consumption of water and are biggest producers of effluent per unit of production.The concentration and composition of the effluent depends upon operating methods andthe size and design of the processing plant.The dairy industry generates on an average 6-10 litres of waste water per litre of the milk processed. It has relatively high organic matter, suspended solids, trace organic nutrients which are essential for growth of crop plant. Thus, the utilization of the dairy effluent for irrigation can be an eco friendly approach for its disposal. The present study was carried out to study the influence of dairy effluent on seed germination, seedling growth and biomass production in mung bean (Vigna radiata) and mustard (Brassica nigra). The seeds of both the plant species were grown in petriplates and pots irrigated with various concentrations of dairy effluent (20, 40, 60, 80 and 100%). The dairy effluent concentration of 20% was more favorable for total growth parameters viz., the germination percentage, the shoot length, dry weight and wet weight both in mustard and mung bean. Among different concentrations, 100% concentration of effluent caused inhibitory effect. Thus, it is recommended that only after suitable dilution, the dairy effluent can be effectively used for irrigation.

Increasing soil salinity due to climate change complicating weed management. Rhynchosia capitata is becoming an increasing problem in summer crops, such as cotton, soybean, pearl millet and mungbean worldwide. Study was conducted to evaluate the impact of four types of salts stresses (NaCl, Na2SO4, CaCl2 and NaHCO3) at six different levels (0, 50, 100, 150, 200 and 250 mM) on R. capitata seeds of different sizes including small, medium and large. Results revealed that R. capitata can germinate over a wide range of salt stress but as the salinity level was increased to 250 mM the germination percentage and seedling growth decreased significantly. Larger seeds have more potential to germinate and grow vigorously at an increased salt concentration as compared to medium and small seeds. Salt stress caused 40-73%, 59-96% and 40-100% inhibition in seed germination, seedling length and dry weight, respectively. Among various salt stresses CaCl2 showed less inhibition of R. capitata. The higher tolerance of this weed to wide range of salt stresses is alarming factor under current and anticipated increase in salinity, as it will disturb management plans by changing critical completion period and threshold level due to more adaptability of weed under stress than crop plants.

Despite the documented significance of carbon-based nanomaterials (CNMs) in plant development, the knowledge of the impact of carbon nanoparticles (CNPs) dosage on physiological responses of crop plants is still scarce. Hence, the present study investigates the concentration-dependent impact of CNPs on the morphology and physiology of Vigna radiata. Crop seedlings were subjected to CNPs at varying concentrations (25 to 200 µM) in hydroponic medium for 96 h to evaluate various physiological parameters. CNPs at an intermediate concentration (100 to 150 µM) favor the growth of crops by increasing the total chlorophyll content (1.9-fold), protein content (1.14-fold) and plant biomass (fresh weight: 1.2-fold, dry weight: 1.14-fold). The highest activity of antioxidants (SOD, GOPX, APX and proline) was also recorded at these concentrations, which indicates a decline in ROS level at 100 µM. At the highest CNPs treatment (200 µM), aggregation of CNPs was observed more on the root surface and accumulated in higher concentrations in the plant tissues, which limits the absorption and translocation of nutrients to plants, and hence, at these concentrations, the oxidative damage imposed by CNPs is evaded with the rise in activity of antioxidants. These findings show the importance of CNPs as nano-fertilizers that not only improve plant growth by their slow and controlled release of nutrients, but also enhance the stress-tolerant and phytoremediation efficiency of plants in the polluted environment due to their enormous absorption potential.

Background: Aspergillus niger and A. flavus cause rotting, damping-off, loss in germination and toxification of oil seeds. Aspergillus is a common mold in tropical and Sub-tropical countries and causes aflatoxin contamination. A. flavus and A. niger were responsible for storage rot of groundnut. In addition to storage rot, aflatoxin contamination also leads to adverse effects on consumer health. Therefore, present study was conducted to estimate the impact of both A. niger and A. flavus on seed quality parameters of groundnut. Methods: Effect of major seed borne fungi A.niger and A. flavus on seed quality characters of thirteen different genotypes of groundnut was observed in the present study. All the seedling quality characters were measured as per ISTA guidelines. Result: On an average A. niger caused 25.14, 25.18, 43.99, 26.20 and 44.75 per cent reduction in seed germination, seedling length, seedling vigour index I, seedling dry weight and seedling vigour index II, respectively, over the control whereas A. flavus caused average per cent reduction of 22.38, 24.23, 41.18, 23.92 and 40.95 in seed germination, seedling length, seedling vigour index I, seedling dry weight and seedling vigour index II, respectively, over the control.

BACKGROUND Cell phone use brought convenience to people, but using phones for a long period of time or in the wrong way and with a wrong posture might cause damage to the human body. OBJECTIVE To assess the impact of improper cell phone use on transport and chronic injuries. METHODS Studies were systematically searched in PubMed, EMBASE, Cochrane, and Web of Science up to April 4, 2019 and relevant reviews were searched to identify additional studies. A random-effects model was used to estimate the overall pooled estimates. RESULTS Cell phone users were at a higher risk for transport injuries (RR: 1.37, 95%CI: 1.221.55), long-term use of cell phones increased the transport injury risk to non-use or short-term use (RR: 2.10, 95% CI: 1.632.70). Neoplasm risk caused by cell phone use was 1.07 times that of non-use (95% CI: 1.011.14); Compared with non-use, cell phone use had a higher risk of eye disease, with a risk of 2.03 (95% CI: 1.273.23), the risk of mental disease was 1.26 (95% CI: 1.171.35), the risk of neurological disorder was 1.16 (95% CI: 1.021.32), and a pooled risk of other chronic injuries was 1.20 (95% CI: 0.981.59). CONCLUSIONS Cell phone use at inappropriate situations has a negative impact on the human body. Therefore, it is necessary to use cell phones correctly and reasonably.

Phytoremediation is a cost-effective and environmentally friendly approach that can be used for the remediation of metals in polluted soil. This study used a hedge plant–calico (Alternanthera bettzickiana (Regel) G. Nicholson) to determine the role of citric acid in lead (Pb) phytoremediation by exposing it to different concentrations of Pb (0, 200, 500, and 1000 mg kg−1) as well as in a combination with citric acid concentration (0, 250, 500 µM). The analysis of variance was applied on results for significant effects of the independent variables on the dependent variables using SPSS (ver10). According to the results, maximum Pb concentration was measured in the upper parts of the plant. An increase in dry weight biomass, plant growth parameters, and photosynthetic contents was observed with the increase of Pb application (200 mg kg−1) in soil while a reduced growth was experienced at higher Pb concentration (1000 mg kg−1). The antioxidant enzymatic activities like superoxide dismutase (SOD) and peroxidase (POD) were enhanced under lower Pb concentration (200, 500 mg kg−1), whereas the reduction occurred at greater metal concentration Pb (1000 mg kg−1). There was a usual reduction in electrolyte leakage (EL) at lower Pb concentration (200, 500 mg kg−1), whereas EL increased at maximum Pb concentration (1000 mg kg−1). We concluded that this hedge plant, A. Bettzickiana, has the greater ability to remediate polluted soils aided with citric acid application.
