“…Additionally, under water‐limited conditions, the Asn + SNP treatment showed a rise in IWP, indicating that it may be a potential method for enhancing cotton production's water usage efficiency. The use of SNP was found to dramatically raise IWP by up to 30% in a research by Yavuz et al (2023). The study also showed that using SNP in lettuce growing under water‐scarce conditions led to a 20% reduction in water use.…”

Asparagine (Asn) and nitric oxide (NO) can enhance plant tolerance to abiotic stress, but their interaction is not well understood. Cotton is a vital resource for the textile industry, but its yield is reduced by drought stress, which could threaten its global supply in a warming and stressful world. Improving cotton's drought tolerance is crucial for supporting the textile industry. Two simultaneous field experiments were conducted to study the effect of Asn and sodium nitroprusside (SNP), a NO donor, on cotton's drought tolerance. Two irrigation treatments were applied: control (C: 100% A pan) and drought stress (50% A pan). The plants were also sprayed with two plant stimulants before imposing drought stress: Mock control, 20 mM Asn, and 0.2 mM SNP, either alone or together. Drought stress impaired plant growth, photosynthesis, yield, nitrogen metabolism, and antioxidant defense, while increasing oxidative stress and free amino acid levels. However, Asn and SNP treatments alleviated these negative effects and improved antioxidant enzyme activity, plant growth, yield, and nitrogen content. The Asn + SNP treatment also increased irrigation water productivity under water‐limited conditions, suggesting its potential for enhancing water use efficiency in cotton production. The combined treatment was more effective than the single treatments, indicating a synergistic effect of Asn and SNP in enhancing drought tolerance in cotton. These results imply that Asn and SNP could be useful tools for sustaining cotton production under drought conditions by boosting nitrogen metabolism and antioxidant defense, thereby contributing to the global supply of cotton and supporting the textile industry.

“…Under these conditions, there was an impairment of gas exchange, reduction in transpiration rate, stomatal conductance and CO 2 assimilation, and consequently inhibition of the proper functioning of photosynthesis. The decrease in photosynthesis is related to the reduction in the chlorophyll content of lettuce leaves under stress conditions [12]. Chlorophyll is important in the process of energy conversion in the plant as light energy captured by chlorophyll is used to convert water and CO 2 into organic compounds such as glucose, essential for the energy production required for the growth and development of plants [30].…”

“…There are two typical lettuce production systems, hydroponic and traditional soil cultivation [7]; regardless of the production system, it is a demanding crop in terms of irrigation; that is, in conditions of water deficit, it can have a negative impact on its growth and development. The negative effects caused in plants due to water deficit occur in morphological, productive, physiological, biochemical and molecular aspects [8], such as yield and biomass reduction [9,10], stomatal closure to reduce water loss through transpiration, compromised CO 2 availability [11], reduced photosynthetic performance, and chlorophyll degradation [12]. However, the water deficit technique has the potential to increase the post-harvest quality of lettuce, such as increasing phenolic and antioxidant content [13], and maximize water productivity and economic returns [14].…”

In regions where water is a limited resource, lettuce production can be challenging. To address this, water management strategies like deficit irrigation are used to improve water-use efficiency in agriculture. Associating this strategy with silicon (Si) application could help maintain adequate levels of agricultural production even with limited water availability. Two lettuce crop cycles were conducted in a completely randomized design, with a factorial scheme (2 × 3), with three irrigation levels (60%, 80% and 100%) of crop evapotranspiration (ETc), and with and without Si application. To explore their combined effects, morphological, productive, physiological and nutritional parameters were evaluated in the crops. The results showed that deficit irrigation and Si application had a positive interaction: lettuce yield of the treatment with 80% ETc + Si was statistically similar to 100% ETc without Si in the first cycle, and the treatment with 60% ETc + Si was similar to 100% ETc without Si in the second cycle. Photosynthetic rate, stomatal conductance, intercellular CO2 concentration, transpiration rate and total chlorophyll content increased under water-stress conditions with Si application; in the first cycle, the treatment with 80% ETc + Si increased by 30.1%, 31.3%, 7.8%, 28.46% and 50.3% compared to the same treatment without Si, respectively. Si application in conditions of water deficit was also beneficial to obtain a cooler canopy temperature and leaves with higher relative water content. In conclusion, we found that Si applications attenuate water deficit effects and provide a strategy to ameliorate the yield and water productivity in lettuce crops, contributing to more sustainable practices in agriculture.

“…SNP treatment alleviated drought-induced decreases of leaf RWC in 7-day-old wheat plants [20]. Exogenous SNP treatment of lettuce (Lactuca sativa L.) improved photosynthesis by increasing chlorophyll synthesis; activated antioxidant enzymes, protecting lettuce plants against oxidative damage; and increased irrigation water consumption, thus increasing the yield under soil drought [23]. Thus, our results confirm the important role of NO in maintaining the water status of plants under drought, which is realized at physiological, biochemical and molecular levels through the modulation of stomatal movements; the increased synthesis of low-molecular-weight osmolytes: proline, glycine-betaine, and sugars; as well as through the changes in the gene expression activity which encode enzymes catalyzing the metabolism of osmoprotectants [2][3][4]13,14,17,20,[45][46][47].…”

Nitric oxide (NO) is a universal signaling molecule with important regulatory functions in the plant’s life cycle and adaptation to a wide spectrum of environmental stresses including drought. The effect of pre-sowing seed treatment with the donor of NO sodium nitroprusside (SNP, 200 μM) on wheat Triticum aestivum L. plants subjected to dehydration (PEG-8000, 12%) was investigated. SNP pretreatment stimulated germination and seedling growth in normal conditions and protected them under dehydration. These effects were confirmed by percentage of seed germination, changes in fresh and dry weight of 5–6-day-old seedlings, as well as by seedlings’ linear dimensions, visual appearance, and mitotic index of the root apical meristem. Assessment of the transpiration intensity (TI) and relative water content (RWC) showed that SNP pretreatment helped to maintain the water status of seedlings subjected to dehydration stress. The data obtained by enzyme-linked immunosorbent assay (ELISA) suggested that the positive effects of SNP may be due to its influence on the phytohormonal system. SNP pretreatment induced an increase in the level of indolylacetic acid (IAA) and especially cytokinins (CK), while essential changes in ABA content were not detected. Water deficiency caused a substantial increase in ABA content and a decrease in the levels of CK and IAA. Pre-sowing SNP treatment decreased stress-induced fluctuations in the content of all studied phytohormones. Using reverse-transcription PCR (RT-PCR), we obtained data on the increase in expression of the TADHN dehydrin gene in SNP-pretreated seedlings under normal and, especially, under dehydration conditions. These findings may indicate the participation of dehydrins in NO-induced defense reactions in wheat plants under water stress. Furthermore, exogenous NO had a stabilizing effect on membrane cellular structures, as evidenced by the reduction of electrolyte leakage (EL) levels and malondialdehyde (MDA) content in dehydrated wheat seedlings under the influence of pre-sowing SNP treatment.
