“…MEL effectively improved proline level, metabolite content, antioxidant enzymes, and their gene expression levels in Brassica napus under Se toxicity (Ulhassan et al, 2019). In another study, MEL treatment considerably enhanced net photosynthetic rate, growth traits, leaf gas exchange elements, and maintained macro-and micro-nutrient content in pepper leaves under B toxicity (Sarafi et al, 2017). MEL application improved antioxidant enzyme activities and root growth and reduced the MDA and proline levels in the roots of melon seedlings under Cu toxicity (Hu et al, 2020).…”

“…In addition, MEL further enhanced the antioxidant enzyme system, along with a decline in the ROS level in spinach seedlings (Moussa and Algamal, 2017). MEL positively regulates the growth of tobacco under lead stress (Kobylińska et al, 2017), radish under Cd toxicity (Xu et al, 2020), and pepper under boron stress (Sarafi et al, 2017). Table 5 provides an overview of the protective functions of MEL in horticultural crops under heavy metal toxicity.…”

Global warming in this century increases incidences of various abiotic stresses, restricting plant growth and productivity and posing a severe threat to global food production and security. Different phytohormones are produced by plants to mitigate the adverse effects of these stresses. One such phytohormone is melatonin (MEL), which, being a potential bio-stimulator, helps to govern a wide array of functions in horticultural crops. Recent advancements have determined the role of MEL in plants’ responses to abiotic stresses. MEL enhances physiological functions such as seed germination, growth and development, seedling growth, root system architecture, and photosynthetic efficiency. The potential function of MEL in stressful environments is to regulate the enzymatic and non-enzymatic antioxidant activity, thus playing a role in the substantial scavenging of reactive oxygen species (ROS). Additionally, MEL, as a plant growth regulator and bio-stimulator, aids in promoting plant tolerance to abiotic stress, mainly through improvements in nutrient uptake, osmolyte production, and cellular membrane stability. This review, therefore, focuses on the possible functions of MEL in the induction of different abiotic stresses in horticultural crops. Therefore, this review would help readers learn more about MEL in altered environments and provide new suggestions on how this knowledge could be used to develop stress tolerance.

“…Alamri et al (2018) indicated effects of soil boron concentrations on germination and seedling growth parameters and reported that low boron concentrations (0.5 mg L -1 ) had positive effects on germination and seedling growth parameters, but high concentrations (1.0 mg L -1 ) reduced germination rates and seedling growth parameters significantly. In pepper plants, boron toxicity symptoms (slight chlorosis along the leaf edges) were encountered when the boron concentration of nutrient solution increased to 5.0 mg L -1 (Sarafi et al, 2017). Decreasing germiantion ratios and germination index values of pepper plants were reported at boron concentrations of over 2.0 mg L -1 (Turhan, 2018).…”

Boron toxicity constitutes a limiting factor on seed germination. Salicylic acid-like plant growth regulators play an important role in alleviation the negative effects of boron stress. The research was carried out to determine the germination properties of seeds (pepper, eggplant, watermelon) with and without salicylic acid (SA) pre-application at different boron (B) concentrations. Experiments were conducted in randomized plots design with 4 replications. Seed germination percentage, mean germination time, germination index and germination energy values were determined under four different SA (0, 0.5, 1.0 and 2.0 mM) and six different B (0, 1.0, 2.0, 4.0, 8.0 and 16.0 mg L -1 ) doses. The greatest germination percentage, index and energy values and the shortest mean germination time were obtained from 1.0 mg L -1 B dose, on the other hand, increasing B stress negatively influenced germination parameters. Especially at 4.0, 8.0 and 16.0 mg L -1 B stress, 1.0 mM SA supplemented into growing media increased germination parameters of all three vegetable species, reduced the negative effects of boron and positively influenced germination time. Present findings revealed that SA could be used as an efficient tool in alleviation of negative effects of boron toxicity. On the other hand, SA applications were not effective or had quite limited effects on non-B application or low B-application (< 1.0 mg L -1 ) seeds.

“…Pepper (Capsicum annuum L.) is a valuable crop not only because of its economic significance but also of the nutritional value of its fruits, which are a major source of antioxidants (Sarafi et al, 2017) and minerals. A proportion greater than 25% of the worlds' population consumes peppers every day (d) (Namiki, 1990).…”

Boron may affect total uptake of various nutrients and their nutrient use efficiency (NUE) which results in high productivity and low fertilizer cost. Therefore, the objective of this study was to investigate the effect of boron concentration in nutrient solution on total uptake of the various nutrients and their utilization efficiency in pepper plants (Capsicum annuum L.). Four cultivars (Osho, Solario, Odysseo and Arlequin) were treated with 0.5-10 mg B L -1 . Each treatment included five replications with 3 plants and after 20, 40 and 70 days in culture one plant per pot was removed, divided into leaves, shoots and roots and analysed. The cultivars Odysseo and Arlequin have the greatest total phosphorus absorption at 0.5-2.5 mg B L -1 and more Ca at 1-2.5 mg B L -1 , while Odysseo absorbed more magnesium (Mg) per plant at 1 mg B L -1 and 70 d per plant than the other cultivars. Furthermore, Solario, Odysseo, and Arlequin absorbed at 70 days more B. Differences were recorded also among the cultivars concerning the rest of the nutrients. The maximum nutrient use efficiency of Solario and Osho for phosphorus and potassium was recorded at 5 mg B L -1 , and in Solario for calcium. Boron use efficiency was maximum for Solario, Osho and Odysseo at 0.5 mg B L -1 and for Fe at 10 mg B L -1 for all the cultivars. The effect of boron on magnesium, manganese and zinc use efficiency was variable.
