Effects of iron nano-complex and Fe-EDDHA on bioactive compounds and nutrient status of purslane plants

Abstract

Nanoparticles serve as a new fertilization method utilised in agriculture, and their potential effect on medicinal crops has been mainly unexplored. In the present study, using ultrasonic irradiations, a novel nano-sized iron complex has been prepared from aminolevulinic acid and iron (III) nitrate under greenhouse conditions. The obtained Fe nano-sized energy dispersive X-ray spectroscopy complex has been characterized by two methods, i.e. Fourier-transform infrared spectroscopy and spectra. The morphology and size of the nano-complex were also determined using transmission electron micrographs and showed an acceptable size in the nano range (5-25 nm). In this work, purslane plants were supplied with Fe (III)-aminolevulinic acid asa new nano-sized complex and Fe-EDDHA. The mineral nutrient concentrations, total phenolic, ascorbic acid contents and antioxidant activity were the highest in the plants treated with the Fe-ALA nano-complex. Catechin was the predominant phenolic compound in all treated plants. The Fe nano-complex at the rate of 0.2% induced extra high-value phenolic compounds. The shoot Fe, Zn, N, Mg, Ca and K contents were also higher in the plants treated with the Fe nano-complex than in both the control group and the plants treated with Fe-EDDHA. In general, the nutritional and pharmaceutical quality of Portulaca oleracea L. improved when using the nano-sized Fe-ALA complex as a new iron source.

Response of Narcissus Constantinople 'Double Roman' Plants of Some Natural and Chemical Fertilizers

“…As well as the ease of penetration of Fe and Zn through plant tissues, also led to the balance between its components. Totally are consistent withDatir et al, 2010;Khalifa et al, 2011;Chohura et al, 2012;Saeedi et al, 2015;Li and Mattson, 2015;Tavallali, 2018;Abbas et al, 2020 andRizk andElngar, 2020.…”

“…While the significant values were equal between all the spraying treatments, whether with chemical chelates or macrophytes extracts added to drenching the soil or alone, as in the characteristics of perianth diameter and scape circumference in 1 st season and pedicel length, tube length and inflorescence dry weight in both seasons and inflorescence fresh weight in 2 nd season. All the promising results in the characteristics of flowering are due to the importance of the role of microelements in the metabolism of the plants as Cempel and Nikel, 2006;Soltan, 1999 andKhalifa et al, 2011;Chohuraet al, 2012;Saeediet al, 2015 andTavallali, 2018. In addition, hydrophytes extract contains many components like carbohydrates, hormones or growth stimulations, cytokinins, vitamins, amino acids and enzymes, all of which are necessary and essential for plant flowering processes as mentioned by Wile et al, 1978;Reed and Gadd, 1990;Fortuna et al, 2005;Haroon, 2009;Rai, 2009;Tripathi et al, 2015;Nabtiet al, 2016;Sarwar et al, 2017;Kushwaha et al, 2018 andLead et al, 2018. (cm), 7) shows the marketability of bulbs represented by bulb circumference (cm), number of bulbs, total bulbs fresh and dry weight (g) and roots dry weight (g).…”

“…We also found an increase in L-ascorbic acid in plant treated with 0.75% and 3% Fe 2 O 3 -NPs. Tavallali [45] noted a higher ascorbic acid content in the aerial parts of purslane when plants were exposed to Fe(III)-aminolevulinic acid (Fe-ALA) nano-complex in comparison to the control.…”

Winter Cultivation and Nano Fertilizers Improve Yield Components and Antioxidant Traits of Dragon’s Head (Lallemantia iberica (M.B.) Fischer & Meyer)

“…Nano complex of Fe could increase antioxidant activity in Portulaca oleracea. These nutrients play a key role in cellular mechanisms, osmotic regulation, and enzyme synthesis, and provide a large number of biochemical constitutions for many metabolic pathways, to improve plant quality and quantity [40,41]. There is a direct relationship between phenol compounds and DPPH radical scavenging activity, so that when the phenol compound content is increased, DPPH radicals are scavenged at a faster pace.…”
