“…The increase in growth indicators in plants treated with Si and/or SA demonstrates the mitigating effects of these elements on abiotic stress disorders, thus enabling plants to tolerate stress (Melo-Filho et al, 2019;Silva et al, 2019a, b). S. terebinthifolia seedlings subjected to water stress with application of SA developed better when cultivated under water (100% daily irrigation capacity) and under water deficit by 12 days, reinforcing the potential of SA to mitigate stressful effect (Saracho et al, 2021). Carvalho et al (2016) suggests that the increment in height is an increase was a response to the flooding condition as a strategy to keep the leaves above the water level, as observed for Peltophorum dubium (Sprengel) Taub.…”

“…The Si can positively affect the absorption of nutrients such as N and other cations that contribute to plant growth (Etesami and Jeong, 2018). Regarding SA, this result can be attributed to its participation in several metabolic processes, especially optimization of water use and regulation of metabolic processes, resulting in an increase in growth (Saracho et al, 2021;Santos et al, 2022a).…”

Flooding can damage the photosynthetic apparatus and initial growth of Schinus terebinthifolia. We aimed this study evaluates the potential of silicon (Si) and salicylic acid (SA) as mitigating agents on the ecophysiological responses and initial growth of S. terebinthifolia subjected to flooding periods. Seedlings were grown under the following conditions: 1) control (non-flooded): daily irrigation, 2) Flooded (F): storage of seedlings in a 500 L plastic pool, keeping the water depth at ± 2.0 cm above the substrate level, 3) F + 1.0 mM Si, 4) F + 2.0 mM Si, 5) F + 1.5 mM SA, and 6) F + 3.0 mM SA, and evaluated to 15 and 30 days. We observed that flooded seedlings formed hypertrophied lenticels on the stem on the 7th day as a stress adjustment strategy. S. terebinthifolia is sensitive to flooding, although it maintains a stable gas exchange for up to 15 days in this condition. The applications of 1.0 mM Si mitigated the pronounced decrease of gas exchange by 30 days. Using 1.0 mM Si and 3.0 mM SA contributed for integrity of the photosynthetic apparatus and to photochemical activities in the reaction centers, in addition favors to higher seedling biomass and quality under flooding. Foliar application of Si and SA is promising practice for photosynthetic metabolic and initial growth of S. terebinthifolia seedlings under flooded stress.

“…Cultivation management techniques that can mitigate the possible damage caused by flooding on plant metabolism have been developed. Among the promising alternatives, foliar application of salicylic acid (SA), a phenolic phytohormone, can alleviate the negative effects of abiotic stresses by contributing to the antioxidant system, metabolic regulation, and plant growth (Saracho et al, 2021;Foresti et al, 2022;Santos et al, 2022b).…”

Flooding is a stressful condition that causes damage to the photosynthetic apparatus, negatively affecting the growth of seedlings of fruit species, including Hymenaea courbaril L. Studies on physiological management, such as exogenous application of phytohormones, to alleviate abiotic stress have increased. The objective of this study was to evaluate the effect of foliar application of salicylic acid (SA) on H. courbaril seedlings subjected to flooding. The seedlings received foliar application of four concentrations of SA (0, 100, 200, and 400 mg L-1) and were subjected to two water regimes: a) control - non-flooded and irrigated daily and b) flooded - seedlings were placed in a plastic pool, keeping the water depth at ± 5.0 cm above the substrate level. After 35 days, we evaluated the gas exchange, initial growth, quality, and potential ecological resilience of the seedlings. All flooded seedlings survived, but had reduced photosynthesis, carboxylation of Rubisco efficiency, and water-use and stomatal conductance when they received 100-300 mg L-1 SA. The seedlings that received between 100 and 300 mg L-1 SA had greater growth, quality, and phenotypic plasticity. Foliar application of SA did not mitigated the effect of flooding on gas exchange but contributed to the growth of H. courbaril seedlings.

Morphophysiological changes in seedlings of two wood species after application of salicylic acid

Morphophysiological changes in seedlings of two wood species after application of salicylic acid 1The forestry production sector uses several strategies to minimize post-planting seedling losses. Some practices can modulate characteristics of interest for plant growth and defense, including changes in the light exposure, reduced watering, fertilization, and chemical or mechanical stimulus. This work quantified morphophysiological changes on Schinus terebinthifolius and Cedrela fissilis seedlings resulting from the application of salicylic acid for eight weeks. The experimental design was completely randomized, composed of four treatments (0, 100, 200, and 300 mg L -1 of salicylic acid). The quantified variables included height, diameter, and dry matter mass of the root and aerial parts. Additionally, leaf area, root-cell electrolyte loss, lignin content in roots, and stem plus phenolic compounds were quantified. On aroeira seedlings, the height, aerial, and radicular dry matter masses and leaf area were reduced while the diameter and the lignin content increased directly as a function of salicylic acid doses. In cedro seedlings the dose of 100 mg L -1 , however, resulted in a better balance of plant biomass and would, therefore, be the most indicated dose for the species. The application of salicylic acid for 8 weeks on seedlings of both species resulted in the most relevant morphophysiological modifications correlated with quality characteristics of seedlings of woody species.
