Optimised synthesis of ZnO‐nano‐fertiliser through green chemistry: boosted growth dynamics of economically important L. esculentum

Abstract

Mounting-up economic losses to annual crops yield due to micronutrient deficiency, fertiliser inefficiency and increasing microbial invasions (e.g. attack on tomatoes) are needed to be solved via nano-biotechnology. So keeping this in view, the authors' current study presents the new horizon in the field of nano-fertiliser with highly nutritive and preservative effect of green fabricated zinc oxide-nanostructures (ZnO-NSs) during (tomato) growth dynamics. ZnO-NS prepared via green chemistry possesses highly homogenous crystalline structures well-characterised through ultraviolet and visible spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction and scanning electron microscope. The ZnO-NS average size was found as small as 18 nm having a crystallite size of 5 nm. were grown in different concentrations of ZnO-NS to examine the different morphological parameters includes time of seed germination, germination percentage, the number of plant leaves, the height of the plant, average number of branches, days count for flowering and fruiting time period along with fruit quantity. Promising results clearly predict that bio-fabricated ZnO-NS at optimum concentration resulted as growth booster and dramatically triggered the plant yield.

Interactive effects of zinc oxide nano particles and different light regimes on growth and silymarin biosynthesis in callus cultures of Silybum marianum L.

“…The enhancement of callus growth by employing ZnO NPs can be extrapolated in terms of its potential to provide Zn ions at a sufficient level in the culture media as an essential micronutrient. Zn is supplied to plants cells to tremendously activate the chloroplast pathways [39]. Still, it is unclear that how ZnO NPs impact the chloroplast in a plant cell.…”

Foliar Application of Low Concentrations of Titanium Dioxide and Zinc Oxide Nanoparticles to the Common Sunflower under Field Conditions

“…Moreover, zinc has previously been recorded herein as an essential micronutrient for plant growth and development [75], and our research into its application to the Neostar hybrid sunflower cultivar recorded greater resistance to both drought and water-logging. Zinc therefore has a most important function in our hybrid's production process because the ZnO nanoparticles are quickly transported into the sunflower and participate in its metabolic processes [76]. TiO 2 , SiO 2 , and carbon nanotubes are also part of the new generation of nanoparticle fertilisers.…”

Green fabricated zinc oxide nanoformulated media enhanced callus induction and regeneration dynamics of Panicum virgatum L.

“…ZnO-NPs obtained were dehydrated utilizing hot air-drying oven (Memmert) at 60˚C for 6 hr. Moreover, to obtain the crystalline zinc oxide nanoparticles calcinations were done at 400˚C for 2 hr in Gallenkamp-furnace [25].…”

“…The results showed very low callogenesis 16% at 50 mg/L in internodes, but no callus was recorded at that concentration in seeds as explants. The increase in callus induction frequency using ZnO NPs can be explained in terms as Zn is a micronutrient and can be supplied to plants NPs [25] however, the effects were concentration dependant and above 20-30 mg/L was proved to increase the callogenesis. Data clearly reflect the positive response of ZnO-NPs at low concentration up to 30 mg/L.…”
