“…The dehydrogenase activity as the major cell respiration enzyme, which is higher in nano-primed seed roots than in non-primed control treatments and other processes, can be directly linked to fast water consumption in nano-primed seeds. Higher water consumption can thus improve the germination and development of seeds through complex networks.Moreover, in recent studies, various metal-based NPs such as AgNPs [ 79 , 80 ], gold (Au)NPs [ 81 ], copper (Cu)NPs [ 82 , 83 ], iron (Fe)NPs [ 84 ], iron pyrite (FeS 2 )NPs [ 85 ], titanium dioxide (TiO 2 )NPs [ 86 , 87 ], zinc (Zn)NPs [ 88 ], zinc oxide (ZnO)NPs [ 89 – 91 ], and carbon NPs such as fullerene [ 92 ] and carbon nanotubes [ 93 ] have been utilized used as pre-treatment of seeds for activating germination, growth, and stress tolerance in various crop species. Gold NPs (AuNPs) seed priming often increases water absorption in maize plants [ 7 ].…”

Nano-priming is an innovative seed priming technology that helps to improve seed germination, seed growth, and yield by providing resistance to various stresses in plants. Nano-priming is a considerably more effective method compared to all other seed priming methods. The salient features of nanoparticles (NPs) in seed priming are to develop electron exchange and enhanced surface reaction capabilities associated with various components of plant cells and tissues. Nano-priming induces the formation of nanopores in shoot and helps in the uptake of water absorption, activates reactive oxygen species (ROS)/antioxidant mechanisms in seeds, and forms hydroxyl radicals to loosen the walls of the cells and acts as an inducer for rapid hydrolysis of starch. It also induces the expression of aquaporin genes that are involved in the intake of water and also mediates H2O2, or ROS, dispersed over biological membranes. Nano-priming induces starch degradation via the stimulation of amylase, which results in the stimulation of seed germination. Nano-priming induces a mild ROS that acts as a primary signaling cue for various signaling cascade events that participate in secondary metabolite production and stress tolerance. This review provides details on the possible mechanisms by which nano-priming induces breaking seed dormancy, promotion of seed germination, and their impact on primary and secondary metabolite production. In addition, the use of nano-based fertilizer and pesticides as effective materials in nano-priming and plant growth development were also discussed, considering their recent status and future perspectives.

“…It is worth mentioning that zinc is an essential element for plants since it promotes the enzymatic and hormonal activity of the plant. In turn, zinc stimulates the synthesis of tryptophan, which stimulates the genesis of auxins, cytokinins and gibberellins, all of them hormones involved in the growth and development of plants [ 46 , 47 ]. Intriago’s research [ 48 ] affirmed that the use of zinc stimulates the development of new tissues, contributing to the growth and development of the seedling [ 49 , 50 , 51 ].…”

Tomato is an important crop due to its nutritional contributions and organoleptic properties, which make it an appetizing vegetable around the world. In its sowing, the use of seed is the most accessible propagation mechanism for farmers. However, the induction to germination and emergence is often limited in the absence of stimulants that promote the development and growth of the seedling, added to the interference of infectious agents that notoriously reduce the vitality and viability of the seed. Given this, it was proposed as a research objective to determine the effect of zinc oxide nanoparticles (ZnO NPs) mediated by a green route on the germinative characteristics of Lycopersicon esculentum Mill. 1768 “tomato”. The experimental phase consisted of the synthesis of ZnO NPs and its subsequent characterization. After its synthesis, its inoculation was conducted during the germination of seeds of L. esculentum, considering six sample groups for the treatment with zinc nanoparticles (T1: Control; T2: 21.31 ppm; T3: 33.58 ppm; T4: 49.15 ppm; T5: 63.59 and T6: 99.076 ppm). The results indicate that concentrations close to 100 ppm of ZnO NPs are ideal in the treatment of L. esculentum seeds, due to the promotion of enzymatic and metabolic activity to achieve cell elongation; likewise, the biosynthesized nanoparticles showed no phytotoxicity, due to the fact that, in all the treatments, there were processes of germination and emergence. This was linked to the generation of a Zn0-phenolate complex through a chelating effect, which generates compatibility with the seed and, compared to classic inorganic synthesis, usually shows phytotoxicity. In this sense, green synthesis is presented as a great alternative in this type of application.

“…Nanoparticles are used in nano fertilizer, nano-pesticides as well as herbicides that are helpful to improve plants development, to manage extreme utilizes associated with chemical substances fertilizers as well as improve survivability towards biotic tension. The effects of various nanoparticles on plant development and phytotoxicity have been documented by a number of substances such as magnetite (Fe3O4) nanoparticles, alumina, zinc, and additionally zinc oxide in relation to seed germination [11]. Wheat can benefit from the addition of nanoparticles to their environment.…”

Most of the early uses of nanotechnology have come from material sciences, although applications in agriculture are still expanding. Due to a few comprehensive reviews, we described application of nanomaterials along with their fate in soil and interaction with soil and plant system. From synthesis to metabolism, nano-fertilizers like zinc, silver, selenium, titanium oxide have enhanced the physio-chemical characteristics of crop plants in every manner conceivable. On the other hand, it has the potential to minimize pesticide use by boosting reactivity and surface area of nanoparticles. Nanotechnology in pesticides will, without a doubt, replace the current way of pesticide application because of its efficacy. Nano-based approaches can readily overcome the constraints of conventional soil remediation technologies. While soil nanomaterials mobility has been investigated in a limited number of research studies, it’s likely the most critical gap in knowing the real risk of their transport. As well as enhancing plant nutrient absorption, nanomaterials may also be used to regulate soil microbial activity and stimulate plant defenses. When it comes to shipping food, nanotechnology has made things easier by extending the shelf life of most foods. While it offers tremendous potential for agricultural applications, the health effects of nanoparticles on plants, animals, and humans must be thoroughly investigated.
