“…In Experiment 2, Al concentration in the root tissues was 50 times higher than in the cucumber leaves and even higher than in stems or fruits (Table 4 ). This indicates that the endodermis of roots represents a barrier to the transport of Al to the shoot (Dogan et al, 2014 ). Interestingly, this ratio was independent of the type of rootstock used although the absolute Al concentration differed between grafted and non-grafted root systems.…”

Can Adverse Effects of Acidity and Aluminum Toxicity Be Alleviated by Appropriate Rootstock Selection in Cucumber?

Low-pH and aluminum (Al) stresses are the major constraints that limit crop yield in acidic soils. Grafting vegetable elite cultivars onto appropriate rootstocks may represent an effective tool to improve crop tolerance to acidity and Al toxicity. Two greenhouse hydroponic experiments were performed to evaluate growth, yield, biomass production, chlorophyll index, electrolyte leakage, mineral composition, and assimilate partitioning in plant tissues of cucumber plants (Cucumis sativus L. “Ekron”) either non-grafted or grafted onto “P360” (Cucurbita maxima Duchesne × Cucurbita moschata Duchesne; E/C) or figleaf gourd (Cucurbita ficifolia Bouché; E/F). Cucumber plants were cultured in pots and supplied with nutrient solutions having different pH and Al concentrations: pH 6, pH 3.5, pH 3.5 + 1.5 mM Al, and pH 3.5 + 3 mM Al (Experiment 1, 14 days) and pH 6, pH 3.5, and pH 3.5 + 0.75 mM Al (Experiment 2, 67 days). Significant depression in shoot and root biomass was observed in response to acidity and Al concentrations, with Al-stress being more phytotoxic than low pH treatment. Significant decrease in yield, shoot, and root biomass, leaf area, SPAD index, N, K, Ca, Mg, Mn, and B concentration in aerial parts (leaves and stems) in response to low pH with more detrimental effects at pH 3.5 + Al. Grafted E/C plants grown under low pH and Al had higher yield, shoot, and root biomass compared to E/F and non-grafted plants. This better crop performance of E/C plants in response to Al stress was related to (i) a reduced translocation of Al from roots to the shoot, (ii) a better shoot and root nutritional status in K, Ca, Mg, Mn, and Zn concentration, (iii) a higher chlorophyll synthesis, as well as (iv) the ability to maintain cell membrane stability and integrity (lower electrolyte leakage). Data provide insight into the role of grafting on Al stress tolerance in cucumber.

“…It induces the amount of toxic chemicals in the crops and imbalance the nutrients consequently leads toward the toxicities in crops and causes harmful effect on consumers [1,2]. Human activities also play an important role in the heavy metal contaminations [3,4]. Anthropogenic activities in collaboration with the nature affects to increase the heavy metal adversely affects the life by different ways [5].…”

The article is focused on concentration of cadmium in maize and millet collected in 2018-2019 from different district (Sargodha, Faisalabad, Sheikhupura, Lahore and Kasur) of Punjab under different irrigation sources Canal and wastewater. The values of Bioconcentration factor, Translocation factor, Pollution load index, Daily intake of metal, Health Risk Index and Enrichment factor were studied to evaluate the effect of heavy metal accumulation on grains quality and human health. Most of the metals observed in wastewater were present in high amount. Cd concentration increased considerably under wastewater irrigation in soil (1.06 mg/kg) and grains (1.05 mg/kg). Cd showed highest bioconcentration (3.82 mg/kg) in canal water. Wastewater irrigated soil exhibited the maximum Pollution Load Index (PLI) values as compared to control treatment. Under the influence of wastewater irrigation, Cd concentration increased considerably in soil and grains. The purpose of study is the labeling of Maize and Millets species of the area according to their toxicity/desirability for use as human food and fodder.

“…Inhibitory effects of heavy metals on growth and uptake and accumulations of metal elements in Urticaceae members were also shown in previous studies. Such examples are: the altered growth of U. pilulifera upon application of Al stress [34]; reductions on stomatal parameters of U. pilulifera due to excessive aluminium (Al) and Cd exposures [35]; heavy metal (Cd, Cu and Zn) uptake capabilities of Urtica dioica [36]; bioaccumulation of heavy metals by U. dioica.…”

Plants can be used as biological indicators in assessing the damage done by bioaccumulation of heavy metals and their negative impact on the environment. In the present research, Roman nettle (Urtica pilulifera L.) was employed as a bioindicator for cadmium (Cd) pollution. The comparisons between unexposed and exposed plant samples revealed inhibition of the root growth (»25.96% and »45.92% after treatment with 100 and 200 mmol/L Cd concentrations, respectively), reduction in the total soluble protein quantities (»53.92% and »66.29% after treatment with 100 and 200 mmol/L Cd concentrations, respectively) and a gradual genomic instability when the Cd concentrations were increased. The results indicated that alterations in randomly amplified polymorphic DNA (RAPD) profiles, following the Cd treatments, included normal band losses and emergence of new bands, when compared to the controls. Also, the obtained data from F1 plants, utilized for analysis of genotoxicity, revealed that DNA alterations, occurring in parent plants due to Cd pollution, were transmitted to the next generation.
