“…C and lycopene in tomato fruits after the foliar applications of acetyl salicylic acid under chilling stress (Meena et al, 2018). Using of acetyl salicylic acid as foliar application improved TSS under chilling stress (Meena et al, 2017) and under salt stress (Sajyan et al, 2019) in tomato fruits. In this experiment the increment of lycopene due to application of potassium silicate is in harmony with former studies that showed increase in lycopene in tomato fruits which planted in hydroponics, also potassium silicate enhanced Vit.…”

Chilling injury is one of climate change challenges which effect negatively on plant growth of warm season crops. Low temperatures can be overcome by utilization high cost protected cultivation systems such as low tunnels. Open field experiment was conducted in Private farm, located in Mansouria District, at North of Giza Governorate, Egypt during two winter seasons of 2019/ 2020 and 2020/2021 to study the response of tomato cv. Platinum under low temperature conditions for foliar spray with: 1) Melatonin (100 μM); 2) acetyl salicylic acid (178 mM); 3) potassium silicate (250 mg/L); 4) the mix between acetyl salicylic acid (178 mM) and potassium silicate (250 mg/L); 5) water (control) compared with low tunnel and their effects on agronomic, quality traits and productivity with using of Auxin application as common agricultural recommendation in winter season. Our results revealed that plants of control showed the highest significant injury index on leaves and percentage of injury. All treatments reduced of injury index and injury %, especially the tunnel and the mix treatment. The mix between acetyl salicylic acid and potassium silicate significantly enhanced the agronomic traits such as plant height, number of branches, leaf area, shoot fresh weight and number of leaves/plants. All cold mitigators significantly decreased total sugars, proline and total phenols, except acetyl salicylic acid in total sugars in first season, melatonin in proline in first season and potassium silicate in phenols. The highest lycopene and TSS were recorded in the tunnel and the mix treatment, while the highest Vit C were detected for potassium silicate and followed by the Mix treatment then the tunnel. Except melatonin application in first season only, all cold alleviating compounds clearly increased fruit set, and total yield. Tunnel in first season only and the mix treatment in both seasons produced the highest significant early yield, total yield and number of fruits/ plants which were higher in fruit set percentage than other treatments. We suggested using the Mix treatment as low-cost alternative for low tunnels for tomato production under low temperature condition.

“…In literature, it has been demonstrated that BTH is a potent inductor of pathogenesis-related genes, priming the plants for potential pathogenic attacks [ 13 , 14 ]. Similarly, SA itself, a naturally occurring plant hormone, has been used as a priming agent [ 15 ]. SA modulates many cellular processes during abiotic stresses [ 16 ] and is involved in processes, such as stomatal closure, ion uptake and transport, ethylene biosynthesis, transpiration, stress tolerance, membrane permeability, photosynthesis, and growth [ 17 ].…”

The elicitation of plant secondary metabolism may offer interesting opportunities in the framework of sustainable approaches in plant science and in terms of their ability to prime resistance to biotic and abiotic stressors. The broad metabolic reprogramming triggered by different molecular elicitors, namely salicylate (SA), polyamines (PAs), and chitosan, was comprehensively investigated using a metabolomics approach and the tomato (Solanum lycopersicum L.) as the model crop. Six different treatments were compared: a negative control (no treatments), a second negative control treated with 1 M acetic acid (the reference for chitosan, since chitosan was solubilized in acetic acid), and four molecular elicitors, 1 mM 2,1,3-benzothiadiazole (BTH, a positive control), 10 mg/mL chitosan, 0.01 mM SA, and a 0.1 mM PA (putrescine, spermidine, and spermine). All treatments determined a slight increase in biomass, in particular following PA treatment. A broad reprogramming of secondary metabolism could be observed, including membrane lipid remodeling, phenylpropanoid antioxidants, and phytohormone crosstalk. Overall, our results suggest that PAs, SA, and BTH shared a systemic acquired resistance (SAR)-related response, whereas chitosan induced a more distinct induced systemic resistance (ISR)-like jasmonate-related response. These results pave the way towards the possible use of elicitors as a sustainable tool in plant science and agriculture by increasing crop resilience to biotic and abiotic stressors without detrimental effects on plant biomass.

Tolerance and adaptation mechanism of Solanaceous crops under salinity stress

et al. 2022

Solanaceous crops act as a source of food, nutrition and medicine for humans. Soil salinity is a damaging environmental stress, causing significant reductions in cultivated land area, crop productivity and quality, especially under climate change. Solanaceous crops are extremely vulnerable to salinity stress due to high water requirements during the reproductive stage and the succulent nature of fruits and tubers. Salinity stress impedes morphological and anatomical development, which ultimately affect the production and productivity of the economic part of these crops. The morpho-physiological parameters such as root-to-shoot ratio, leaf area, biomass production, photosynthesis, hormonal balance, leaf water content are disturbed under salinity stress in Solanaceous crops. Moreover, the synthesis and signalling of reactive oxygen species, reactive nitrogen species, accumulation of compatible solutes, and osmoprotectant are significant under salinity stress which might be responsible for providing tolerance in these crops. The regulation at the molecular level is mediated by different genes, transcription factors, and proteins, which are vital in the tolerance mechanism. The present review aims to redraw the attention of the researchers to explore the mechanistic understanding and potential mitigation strategies against salinity stress in Solanaceous crops, which is an often-neglected commodity.
