“…This is consistent with the results found by other authors, who reported that high temperature stress can negatively affect the absorption and accumulation of nutrients in the plant [ 53 , 59 , 60 ]. More specifically, wheat and maize subjected to high temperatures showed to be Mg-deficient plants [ 61 ].…”

“…Abdallah et al [ 52 ], in a study conducted with lettuce, indicated that abiotic stress induced the lipid peroxidation of only old leaves, whereas younger leaves tended to accumulate antioxidant compounds. This finding is comparable to that observed in cauliflower leaves [ 53 ]. Thus, the highest lipid peroxidation was found in the outer leaves.…”

“…Our data revealed that cauliflower waste is rich in nutrients ( Table 5 , Table 6 , Table 7 and Table 8 ). In fact, the concentrations of mineral nutrients observed in cauliflower waste were higher than those observed in florets [ 53 ]. This can be ascribed to the fact that crucifer plants under abiotic stress can minimize the concentration of toxic ions in their reproductive organs [ 36 ].…”

“…Similar results were observed in leaves of rose cv. “Dolce Vita”, in melon fruit, and in the cauliflower pellet after the application of exogenous putrescine [ 53 , 59 , 60 ]. This is because polyamines, among other functions, can block or modulate various types of cation channels.…”

This study examines the effect of the exogenous application of polyamine putrescine together with the application of different ratios of nitrate/ammonium (NO3−/NH4+), on the physiology of cauliflower subjected to heat stress. The 50:50 NO3−/NH4+ ratio was the best ratio against heat stress. As a result of the joint application of these compounds, a higher photosynthetic rate, a higher accumulation of both photosynthesis-related compounds and pigments, total proteins, and a change in the status of nutrients were obtained. Particularly, the decrease in content of calcium, chloride and sulphate in plants under heat stress is ameliorated by the ammonium effect. Additionally, it is important to highlight that cauliflower waste contains a higher content of mineral nutrients than floret cauliflower. These effects were more marked in young leaves. Furthermore, a synergistic effect for coping with heat stress between the polyamine and the nutritional treatment was observed. For this, both the application of putrescine and the feeding of plants with a 50:50 NO3−/NH4+ ratio before heat stress is proposed for the first time as an agricultural practice for increasing the thermotolerance of cauliflower cv Moonshine. On the other hand, due to the lower lipid peroxidation rate obtained in cauliflower leaves, these plants could be used for health purposes as ointments or other nutraceutical products, making the cultivation of this kind of cruciferous more sustainable.

“…Polyamines have an important role in the regulation of the plant response to abiotic stresses [ 39 , 40 , 41 ]. Recently, Tajti et al [ 42 ] identified, in Arabidopsis SA-deficient mutants, a possible crosstalk between the SA and polyamine signaling pathways, whilst Collado-González et al [ 43 ] reported in cauliflower that extreme heat increased the content of all polyamines. Gupta et al [ 44 ] indicated that the principal enzymes involved in the polyamine biosynthesis pathway are under complex metabolic and developmental control.…”

Growers in the cultivated areas where the climate change threatens the agricultural productivity and livelihoods are aware that the current constraints for good quality water are being worsened by heatwaves. We studied the combination of salinity (60 mM NaCl) and heat shock stress (43 °C) in pepper plants (Capsicum annuum L. var. Tamarin) since this can affect physiological and biochemical processes distinctly when compared to separate effects. Moreover, the exogenous application of 0.5 mM salicylic acid (SA) was studied to determine its impacts and the SA-mediated processes that confer tolerance of the combined or stand-alone stresses. Plant growth, leaf Cl− and NO3− concentrations, carbohydrates, and polyamines were analyzed. Our results show that both salinity stress (SS) and heat stress (HS) reduced plant fresh weight, and SA only increased it for HS, with no effect for the combined stress (CS). While SA increased the concentration of Cl− for SS or CS, it had no effect on NO3−. The carbohydrates concentrations were, in general, increased by HS, and were decreased by CS, and for glucose and fructose, by SA. Additionally, when CS was imposed, SA significantly increased the spermine and spermidine concentrations. Thus, SA did not always alleviate the CS and the plant response to CS cannot be directly attributed to the full or partial sum of the individual responses to each stress.
