“…Being a plant signaling molecule, it has a role in local and systemic plant defense responses against pathogens through its direct or indirect involvement in sig-naling networks [5]. It helps in providing resistance to biotic and tolerance toward abiotic stress in plants [6,7], such as temperature extremes [8], heavy metals [9], drought [10][11][12], osmotic [13] and salinity [14]. The stress caused by heat is a potential global risk to food security caused due to accelerated temperature and anthropogenic activities, which have aggravated the problem by degrading the agricultural system.…”

In the present era of climate change and global warming, high temperatures have increased considerably, posing a threat to plant life. Heat stress affects the biochemistry, physiology and molecular makeup of the plant by altering the key processes, i.e., photosynthesis, respiration and reproduction which reduces its growth and development. There is a dire need to manage this problem sustainably for plant conservation as well as the food security of the human population. Use of phytohormones to induce thermotolerance in plants can be a sustainable way to fight the adversities of heat stress. Phytohormone-induced thermotolerance proves to be a compelling approach to sustainably relieve the damaging effects of heat stress on plants. Salicylic acid (SA) is an essential molecule in biotic and abiotic defense response signal transduction pathways. When supplied externally, it imparts heat stress tolerance to the plants by different means, viz., increased Heat Shock Proteins (HSP) production, Reactive oxygen species (ROS) scavenging, protection of the reproductive system and enhancing photosynthetic efficiency. The effect of SA on plants is highly dependent on the concentration applied, plant species, plant age, type of tissues treated, and duration of the treatment. The present review paper summarizes the mechanism of thermotolerance induced by salicylic acid in plants under heat stress conditions. It includes the regulatory effects of SA on heat shock proteins, antioxidant metabolism, and maintenance of Ca 2+ homeostasis under heat stress. This review combines the studies conducted to elucidate the role of SA in the modulation of different mechanisms which lead to heat stress tolerance in plants. It discusses the mechanism of SA in protecting the photosynthetic machinery and reproductive system during high-temperature stress.

“…Increasing drought stress significantly reduced the number of branches and seed yield in coriander plants. Water limitation during flowering and seed filling stages increased flower abortion, thus decreasing the seeds number per plant (Yeganehpoor et al, 2019). Reduction in seeds number per plant was also due to a decrement in flower formation (Benezit et al, 2017).…”

“…A moderate concentration of SA may improve the antioxidant capacity of the plants under stress; but a higher rate of this hormone may limit plant growth (Liu et al, 2022). Foliar application of SA enhances branches per plant and seed yield of coriander under different levels of water supply (Yeganehpoor et al, 2019). This natural regulator causes a considerable increment in essential oils extracted from young shoots and peels of grapefruit (Khalid et al, 2018).…”

Drought stress causes physiological disorders and growth restriction, leading to a decrease in crop productivity in the field. Foliar spray of salicylic acid may reduce the adverse effects of this stress on plant performance. Thus, this experiment was laid out as split plot with RCB design in three replicates to assess changes in morpho-physiological traits and essential oil production of dill (Anethum graveolens L.) seeds in response to irrigation intervals (water supply after 70, 100, 130, 160 mm evaporation) and foliar spray of water (control) and salicylic acid (0.6, 1.2 mM). The results showed that, plant height, plant biomass, seeds per umbel and plant were diminished due to water deficit, leading to a decline in seed yield. 1000-seed weight was slightly increased under stress, indicating the extent of drought tolerance of dill plants. Application of salicylic acid improved plant height, branches per plant, leaves per plant, umbels per plant, 1000-seed weight, plant biomass and finally seed yield under different irrigation intervals, especially under water limitation. Essential oil content and yield of seeds were increased with decreasing water supply up to moderate stress. The percentage and yield of essential oil were enhanced up to 54 days after flowering, and thereafter were slightly reduced. In general, application of 1.2 mM salicylic acid on non-stressed and drought-stressed plants was the superior treatment to improve field performance and essential oil production of dill. Therefore, drought tolerance and performance of plants can be promoted by salicylic acid treatment.

Microbial fertilizers containing Bacillus subtilis and Bacillus megaterium isolates are one of the important organic fertilizers, which strengthen the immune system of plants against harmful effects and promote the plant growth by fixing nitrogen from the atmosphere, to obtain better quality products. This study was conducted to determine the effects of different liquid microbial fertilizer doses (0, 500, 1000, 1500, 2000, and 2500 ml 100 L–1) on the yield and yield components of the coriander (Coriandrum sativum L.) grown in Bayburt in 2018 and 2019. The experiment was set up as three replicates in randomized complete block design. The results indicated that there was a considerable variation in the yield and yield components of coriander, and the yield significantly increased as the dose of microbial fertilizer was increased. The maximum essential oil content and seed yield were recorded for the plots grown under the F1 and F3 treatment. It was found that the maximum seed yield was obtained in the F3 treatment (839.0 kg ha–1), and the seed yield decreased in the F4 (754.1 kg ha–1) and F5 (759.9 kg ha–1) treatments. Although the increase in the microbial fertilizer dose increases seed yield, using the fertilizer in optimum dose can be more profitable. Therefore, this study suggests that the fertilizer dose “F3” can improve the productivity of the coriander grown in the areas treated with microbial fertilizer.
