“…Recently, in plants, a large spectrum of antimicrobial and regulatory activities were obtained by the use of CHT-based molecules. For example, CHT nanoparticles (CHTNP), having the properties of CHT and the characteristics of nanoparticles such as surface and interface effect, small size and quantum size effects, were able to act as germination elicitor of Oryza sativa L. [15] and to positively affect seed germination and seedling growth of wheat (Triticum aestivum L.) [16]. In addition, these nanoparticles were able to induce the expression of pathogenesis-related proteins thus enhancing resistance against F. andiyazi in tomato [17] and to inhibit F. oxysporum growth in Zingiber officinale [18].…”

In recent years, the use of complex molecules based on the natural biopolymer chitin and/or on its deacetylated derivative chitosan has resulted in great advantages for many users. In particular, industries involved in the production of drugs, cosmetics, biotechnological items, and food have achieved better results using these particular molecules. In plants, chitin- and chitosan-based molecules are largely used as safe and environmental-friendly tools to ameliorate crop productivity and conservation of agronomic commodities. This review summarizes the results of the last two years on the application of chitin- and chitosan-based molecules on plant productivity. The open questions and future perspectives to overcome the present gaps and limitations are also discussed.

“…Different priming techniques have been applied in agriculture crops to alleviate seed dormancy, improve germination rates, enhance seedling vigor and seedling capacity to grow and establish across a range of sites with varying environmental conditions [13][14][15][16][17][18][19]. Such priming techniques include hydrating seeds in salt solutions (halopriming), solutions of beneficial microbes (biopriming), osmotic solution (osmopriming), plant hormones solutions (hormonal priming), presence of a magnetic field (magneto-priming), solutions mixed with a solid carrier (matriconditioning), solutions of nanoparticles (nanopriming) or hydrating seeds in water (hydropriming) [15,20,21].…”

Nanopriming has been shown to significantly improve seed germination and seedling vigor in several agricultural crops. However, this approach has not been applied to native upland boreal forest species with complex seed dormancy to improve propagation. Herein, we demonstrate the effectiveness of carbon nanoparticles functionalized with carboxylic acids in resolving seed dormancy and improved the propagation of two native upland boreal forest species. Seed priming with carbon nanoparticles functionalized with carboxylic acids followed by stratification were observed to be the most effective in improving germination to 90% in green alder (Alnus viridis L.) compared to 60% in the control. Conversely, a combination of carbon nanoparticles (CNPs), especially multiwall carbon nanoparticles functionalized with carboxylic acid (MWCNT–COOH), cold stratification, mechanical scarification and hormonal priming (gibberellic acid) was effective for buffaloberry seeds (Shepherdia canadensis L.). Both concentrations (20 µg and 40 µg) of MWCNT–COOH had a higher percent germination (90%) compared to all other treatments. Furthermore, we observed the improvement in germination, seedling vigor and resolution of both embryo and seed coat dormancy in upland boreal forest species appears to be associated with the remodeling of C18:3 enriched fatty acids in the following seed membrane lipid molecular species: PC18:1/18:3, PG16:1/18:3, PE18:3/18:2, and digalactosyldiacylglycerol (DGDG18:3/18:3). These findings suggest that nanopriming may be a useful approach to resolve seed dormancy issues and improve the seed germination in non-resource upland boreal forest species ideally suited for forest reclamation following resource mining.

“…In the literature the effect of nanovectors on germination and seedlings are rather sparse and discordant 24,25,26 . Some authors observe that carbon nanomaterials and metal nanoparticles have a positive effect on seed germination and seedling growth 27,28,29 , while others report that plants treated with nanomaterials show symptoms of toxicity 30,31,32 . The negative effects of nanoparticles on plants depend on several factors, the carriers type, size and concentration 33,34 .…”

First developed for biomedical and industrial applications, nanovectors have recently been extended to agriculture. Therefore, innovative plant growing procedures making use of nanoparticles should be adapted to sustainable processes and materials. This work aims at proposing newly synthetized polymeric nanocapsules (NCs) to be used as biocompatible vectors for delivery of bioactive compounds to plants. Nanoparticles were fabricated from lignin, which is the main byproduct of wood processing and is currently a waste material. Lignin can thus find a virtuous fate and be reused in the context of circular economy. Specifically, we loaded lignin NCs with Gibberellic Acid (GA), assessing that stable and reproducible nanoparticles could be obtained in a range of GA content that is relevant for delivery purposes, i.e. 0.5-1.5 mg ml-1. Plain and GA-loaded NCs were characterized by Dynamic Light Scattering (DLS) and Scanning Electron Microscopy (SEM). Assays of cytotoxicity and cargo release were carried out in two model plants, Eruca vesicaria and Solanum lycopersicum. These experiments, conducted both in vitro and in vivo, included the investigations of the percentage of germination, the stem and primary root lengths, as well as the fresh and dry weight of treated plants vs non-treated ones. Furthermore, NCs were loaded with Fluorol Yellow 088 to track their entrance and accumulation in seeds and seedlings.
