“…Improved physical characteristics (histological results) may indicate higher quality physiological functions, as shown by the results of ornamental grasses [42], showing that zinc application increased the resistance to stress effects and had beneficial effects on physical parameters. This was also found to be the case for W. florida 'Eva Rathke' by the histological parameters examined.…”

“…The form and content of zinc oxide-based nanoparticles are determined by chemical or environmental techniques and can be produced from various plant components and parts, including the leaf, stem, root, fruit, or seed [41]. In Pennisetum and Miscanthus species, which are also used in ornamental horticulture, the application of zinc and copper increased the resistance to various stresses [42], while Kumar et al [43] observed an improvement in the skeletal longevity of Gladiolus grandiflous plants under the influence of zinc. In Freesia hybrida, also applied as cut flowers, zinc application increased the tuber number as well as the diameter of tubers in individuals [44].…”

Ornamental horticulture and breeding, as well as urban landscape architecture, are facing increasing challenges driven by an intensely changing climate and urbanisation. The expansion of cities should be combined with an overall growth of green spaces, where ornamental plant species and cultivars will have to withstand a diverse range of environmental conditions, whereby they are often exposed to multiple stress factors. One of the most widely used ornamental shrub species Weigela florida ‘Eva Rathke’ was treated with the growth promoters Bistep with humic and fulvic acid, Kelpak® seaweed extract, and Yeald Plus with a high zinc content to test their applicability in a plant nursery. Bistep decreased the physiological parameters (the transpiration rate by 60%, the evapotranspiration rate by 56.5%, and the proline stress enzyme content level by 82.2%), indicating the stress level of the treated plants. The activity of β-glucosidase decreased with all growth-promoting treatments (11.5% for Kelpak and 9.5% for Yeald Plus), as did β-glucosaminidase (22.1% for Kelpak and 9.8% for Yeald Plus), but Bistep treatment reduced the activity of the enzymes less (9.9% for β-glucosidase and 3.3% for β-glucosaminidase). The measured alkaline phosphatase enzyme activity increased with treatment (by 10.7% for Kelpak, 11.7% for Yeald Plus, and 12.63% for Bistep). Based on the results, it was concluded that Bistep and Yeald Plus may be suitable for use in the studied variety, whereas Kelpak® may not be suggested in plant nurseries for growing W. florida ‘Eva Rathke’ plants.

Role of biostimulants in mitigating the effects of climate change on crop performance

et al. 2022

Climate change is a critical yield–limiting factor that has threatened the entire global crop production system in the present scenario. The use of biostimulants in agriculture has shown tremendous potential in combating climate change–induced stresses such as drought, salinity, temperature stress, etc. Biostimulants are organic compounds, microbes, or amalgamation of both that could regulate plant growth behavior through molecular alteration and physiological, biochemical, and anatomical modulations. Their nature is diverse due to the varying composition of bioactive compounds, and they function through various modes of action. To generate a successful biostimulatory action on crops under different parameters, a multi–omics approach would be beneficial to identify or predict its outcome comprehensively. The ‘omics’ approach has greatly helped us to understand the mode of action of biostimulants on plants at cellular levels. Biostimulants acting as a messenger in signal transduction resembling phytohormones and other chemical compounds and their cross–talk in various abiotic stresses help us design future crop management under changing climate, thus, sustaining food security with finite natural resources. This review article elucidates the strategic potential and prospects of biostimulants in mitigating the adverse impacts of harsh environmental conditions on plants.
