“…Phytohormones can induce an array of physio-biochemical processes and control the transcription of genes for adaptive plant responses to abiotic and biotic stresses (Nephali et al, 2020;Turan et al, 2021;Rana et al, 2022;Clément et al, 2023). Some plant hormones are essential biostimulant compounds used by the crop and horticultural industries (Tadele and Zerssa, 2023). The positive effects of plant biostimulants with traces of phytohormones on yield, fruit diameter, length, chlorophyll content, and overall functional quality have been reported on horticultural crops such as tomato, pepper (Capsicum annuum L.) and spinach (Spinacia oleracea L.) (Turan et al, 2021).…”

Worldwide, it has been recorded extensively that plants are subjected to severe abiotic and biotic stressors. The scientific research community has widely reported that multi-abiotic stressors cause horticultural crop losses, accounting for at least 50 to 70% of the crop yield and quality losses. Therefore, this review focused on the detrimental effects caused by abiotic stress factors occurring in single-, combined- and multi-cell stresses on horticultural plants worldwide, along with the best production systems practices for mitigation during and post-single and combined abiotic or multi-stress damages. A conclusion and recommendation could be reached using the pool of research material, which constituted research articles, reviews, book chapters, thesis, research short communications and industrial short communications from at least twenty-five years ago. Findings showed that some of the leading abiotic stresses are single- and combined abiotic stressors like water deficit, salinity, soil pH, phosphate deficiency, wounding, soil density and pot size. Established commercial and smallholder farmers are globally adapting to plant growth regulators and biostimulants as part of their production systems. However, as much as the effectiveness of biostimulants containing humic acids, algal extracts, plant growth-promoting microorganisms and phytohormones has been reported to promote plant development under multi-stress, only a few studies are focusing on organic phytohormone-based biostimulants on horticultural crops grown under adverse multi stress factoring. In conclusion, the review recommends alternative solutions for emerging South African farmers and growers who cannot afford agricultural insurance options and energy alternatives on the common single- and combined abiotic- or multi-stress-factors.

“…Abiotic stress factors such as drought, salinity, high light, extreme temperatures, etc., can also reduce the quality and productivity of medicinal plants by disrupting their biochemical, metabolic, and physiological processes [ 8 , 9 ]. It has been also established that the application of various biostimulants like phytohormones, plant-growth-promoting Rhizobium, nanomaterials, and biochar can improve the resistance of medicinal plants to stress by stimulating the biosynthesis of primary and secondary metabolites and phytohormones and increasing their chlorophyll contents, antioxidant potential, and nutrient uptake, thereby reducing oxidative stress [ 9 ].…”
