“…Another study conducted with M. piperita showed that the water deficit led to an increase in essential oil content in plants subjected to mild stress, while a moderate water stress treatment caused a significant reduction in the essential oil content at different stages of plant growth (Abdi et al 2019). In M. longifolia under water stress, there was an increase in essential oil yield and a reduction in the percentage of limonene, d-carvone and nutrient percentage (nitrogen and potassium) in the plants, with no significant change in the phosphorus concentration (Singh et al 2022). Several factors can impact the essential oil content in plants, such as the physiological state of the plant, differences In the present study, the essential oil production in spearmint may be more resilient to water stress than other physiological processes such as photosynthesis and transpiration.…”

Drought stress is a critical factor affecting plant growth and development. Understanding the effects of drought on the physiology of medicinal plants can contribute to the implementation of better water management techniques and promote a sustainable production. This study aimed to evaluate the influence of water stress on the growth and development of Mentha spicata L. plants. A completely randomized design was used, with two water conditions: irrigated and non-irrigated. The water deficit negatively affected the dry weight of roots and shoots, with a decrease in the transpiration rate and chlorophyll content, potentially impairing the photosynthetic activity. However, the essential oil production was not affected in plants subjected to water deficiency, indicating that the essential oil production may be more resilient to drought stress in this species.

“…A 3:1 ratio of soil and manure was used to fill the pots (5 kg). Physical and chemical properties such as pH, electrical conductivity (EC), percentage of clay, sand, and silt, percentage of organic carbon, available nitrogen, available phosphorous, and available potassium (NPK) content were analyzed (Table 1) by methods described in our previous work (Singh et al, 2022). Water holding capacity (WHC) of soil was determined by the cup method as described by George et al (2013).…”

Salt stress adversely influences growth, development, and productivity in plants, resulting in a limitation on agriculture production worldwide. Therefore, this study aimed to investigate the effect of four different salts, i.e., NaCl, KCl, MgSO4, and CaCl2, applied at various concentrations of 0, 12.5, 25, 50, and 100 mM on the physico-chemical properties and essential oil composition of M. longifolia. After 45 days of transplantation, the plants were irrigated at different salinities at 4-day intervals for 60 days. The resulting data revealed a significant reduction in plant height, number of branches, biomass, chlorophyll content, and relative water content with rising concentrations of NaCl, KCl, and CaCl2. However, MgSO4 poses fewer toxic effects than other salts. Proline concentration, electrolyte leakage, and DPPH inhibition (%) increase with increasing salt concentrations. At lower-level salt conditions, we had a higher essential oil yield, and GC–MS analysis reported 36 compounds in which (−)-carvone and D-limonene covered the most area by 22%–50% and 45%–74%, respectively. The expression analyzed by qRT-PCR of synthetic Limonene (LS) and Carvone (ISPD) synthetic genes has synergistic and antagonistic relationships in response to salt treatments. To conclude, it can be said that lower levels of salt enhanced the production of essential oil in M. longifolia, which may provide future benefits commercially and medicinally. In addition to this, salt stress also resulted in the emergence of novel compounds in essential oils, for which future strategies are needed to identify the importance of these compounds in M. longifolia.
