Abstract:

Nanotechnology has been developing rapidly in the past few years. Different types of nanoparticles (NPs), varying in size and shape, are currently produced. Nanomaterials are a multipurpose tool used advantageously in agriculture, medicine, electronics, and other areas of life. Nonetheless, little attention has been focused on the utility of NPs in horticultural biotechnology. The aim of our studies was to investigate the effect of various types of nanoparticles in in vitro tissue culture systems of selected ornamental plant species. Silver (AgNPs), gold (AuNPs), and zinc oxide nanoparticles (ZnONPs) were used either in micropropagation, cryopreservation (i.e. storage of biological material in liquid nitrogen; -196oC), and mutation breeding of chrysanthemum (Chrysanthemum × morifolium Ramat.) and bleeding heart (Lamprocapnos spectabilis (L.) Fukuhara). It was found that AuNPs can nearly triple the micropropagation ratio in bleeding heart but also significantly affect the cryoconservation efficiency in this species (an increase or decline in explant survival level was observed depending on the concentration and application method of NPs during the procedure). The quality of plants in the post-acclimatization greenhouse cultivation was also improved after AuNPs treatment. Likewise, zinc oxide nanoparticles can be useful in increasing the micropropagation rate and cryopreservation effectiveness in horticultural plants. Silver nanoparticles, on the other hand, are an efficacious tool in creating novel cultivars of chrysanthemum with distinctive inflorescence color. They are a more effective mutagen than non-ionizing radiation and more accessible than X- or gamma-rays. More studies, especially those concerning the effect of NPs size and shape, are needed to explore the full potential of nanoparticles in horticulture. It will be particularly interesting to verify the usefulness of platinum and copper NPs for the purpose of large-scale reproduction and breeding of plants.
