“…'Red Baron' treated with Maximus Amino Protect. The obtained values were higher than those reported by Majkowska-Gadomska et al (2016), and comparable with those reported by Tendaj et al (2014) and Wojciechowska and Kołton (2014) which ranged from 112 to 207 g depending on the cultivar. Explanations as in Table 1 Following the trend of the weight results, onions of cv.…”

Station owned by the University of Warmia and Mazury in Olsztyn. The experiment had a randomized block design with three replications. The first experimental factor was a number of common onion cultivars: 'Whitney Wing F1', 'Spirit F1' and 'Red Baron'. The second experimental factor was the effect of two plant growth biostimulants; Calleaf Aminovital and Maximus Amino Protect, on the yield and quality of the onions. In the control treatment, plots were sprayed with water. The total yield, marketable yield and the marketable yield as a percentage of the total yield, the weight, vertical diameter and horizontal diameter of each onion bulb, the content of dry matter, total sugars, reducing sugars, L-ascorbic acid and nitrates (V) in the onions were determined in the study. The evaluated cultivars differed significantly with regard to the weight and size of the onions. Onions of cv. 'Whitney Wing F1' were characterized by a greater yield, and the weight, vertical diameter and horizontal diameter of the bulbs were all higher than they were for the remaining cultivars. The concentrations of dry matter, total sugars, L-ascorbic acid and nitrates (V) were higher in cv. 'Red Baron'. The contents of L-ascorbic acid and nitrates (V) were significantly affected by the application of biostimulants, and the effects were more pronounced for onions treated with Maximus Amino Protect. The interaction between the experimental factors had a significant effect on the weight of individual onion bulbs, and on the concentrations of dry matter and L-ascorbic acid in the edible plant parts.

“…Different results were reported by Badałek et al (2016) -25.5 to 27.3 mg N-NO -3 kg -1 fresh weight. In a study by Wojciechowska and Kołton (2014), nitrate (V) levels in common onions ranged from 73.4 mg N-NO -3 kg -1 fresh weight for cv. 'Efekt' to 118.6 mg N-NO -3 kg -1 fresh weight for cv.…”

“…Excessive N accumulation in plant tissues is attributed to the imbalance between uptake and assimilation (Cárdenas-Navarro et al, 1999). As a result, the uptake of nitrate may reduce osmatic pressure that limits the storage of organic solutes in vacuole (Wojciechowska and Kołton, 2014).…”

Abstract:Vegetables are important constituents of the human diet. Heavy metals and nitrate are among the major contaminants of vegetables. Consumption of vegetables and fruits with accumulated heavy metals and nitrate has the potential to damage different body organs leading to unwanted effects. Breeding vegetables with low heavy metal and nitrate contaminants is a cost-effective approach. We investigated 38 water spinach genotypes for low Cd and nitrate co-accumulation. Four genotypes, i.e. JXDY, GZQL, XGDB, and B888, were found to have low co-accumulation of Cd (<0.71 mg/kg dry weight) and nitrate (<3100 mg/kg fresh weight) in the edible parts when grown in soils with moderate contamination of both Cd (1.10 mg/kg) and nitrate (235.2 mg/kg). These genotypes should be appropriate with minimized risk to humans who consume them. The Cd levels in the edible parts of water spinach were positively correlated with the concentration of Pb or Zn, but Cd, Pb, or Zn was negatively correlated with P concentration. These results indicate that these three heavy metals may be absorbed into the plant in similar proportions or in combination, minimizing the influx to aerial parts. Increasing P fertilizer application rates appears to prevent heavy metal and nitrate translocation to shoot tissues and the edible parts of water spinach on co-contaminated soils.
