“…Among these technologies, the use of salt-tolerant crops (Bhardwaj & Kapoor, 2021) and water management practices, such as pulse drip irrigation (Cruz et al, 2018), can be mentioned. Peanut is a crop moderately sensitive to salinity (Yasmine et al, 2019), as already verified in other studies (Alves et al, 2016;Cruz et al, 2018;Yasmine et al, 2019). Therefore, salt stress causes damage to the growth and morphogenesis of peanut, reducing the germination of the seeds and the accumulation of dry matter, influencing the establishment of the morphology of the seedlings and inducing damage to the photosynthetic apparatus (Tian et al, 2019).…”

An efficient water management in irrigation is essential to optimize water efficiency, especially when using brackish water. Thus, the present study was carried out aiming to analyze gas exchanges, pod production, and the water status of peanut plants under increasing levels of salinity (electrical conductivity of 0.12, 1.6, 2.8, 4.0, and 5.2 dS m-1) and the application of the irrigation depth via pulses. A randomized block design in a 5 × 2 factorial scheme was used with four replications, adding up to forty experimental units. The experiment was carried out in drainage lysimeters, at the Federal Rural University of Pernambuco, in open fields from September to November 2019. It was concluded that the use of pulse drip irrigation did not mitigate the deleterious effect of salinity but promoted higher grain and pod production compared to continuous drip irrigation. It was also found that the use of brackish water via pulse drip irrigation promotes greater water use efficiency compared to continuous drip irrigation, and that the increase in the electrical conductivity of the water reduced the water, pressure, and osmotic potentials, along with the osmotic adjustment.

“…Previous reports suggested that there is huge genetic diversity in the salt tolerance among peanut germplasms ( Pal and Pal, 2022 ). The agronomic traits such as survival under salt stress, plant height, relative growth rate reflected the salt tolerance of peanut ( Yasmine et al., 2019 ). The salt tolerance coefficient that was calculated as biomass accumulation ratio under salt stress to unstressed control in each genotype was considered as selection criteria for salt tolerance in peanut ( Pal and Pal, 2022 ).…”

Anthocyanin is an important pigment that prevents oxidative stress and mediates adaptation of plants to salt stress. Peanuts with dark red and black testa are rich in anthocyanin. However, correlation between salt tolerance and anthocyanin content in black and dark red testa peanuts is unknown. In this study, three peanut cultivars namely YZ9102 (pink testa), JHR1 (red testa) and JHB1 (black testa) were subjected to sodium chloride (NaCl) stress. The plant growth, ion uptake, anthocyanin accumulation, oxidation resistance and photosynthetic traits were comparatively analyzed. We observed that the plant height, leaf area and biomass under salt stress was highly inhibited in pink color testa (YZ9102) as compare to black color testa (JHB1). JHB1, a black testa colored peanut was identified as the most salt-tolerance cultivar, followed by red (JHR1) and pink(YZ9102). During salt stress, JHB1 exhibited significantly higher levels of anthocyanin and flavonoid accumulation compared to JHR1 and YZ9102, along with increased relative activities of antioxidant protection and photosynthetic efficiency. However, the K+/Na+ and Ca2+/Na+ were consistently decreased among three cultivars under salt stress, suggesting that the salt tolerance of black testa peanut may not be related to ion absorption. Therefore, we predicted that salt tolerance of JHB1 may be attributed to the accumulation of the anthocyanin and flavonoids, which activated antioxidant protection against the oxidative damage to maintain the higher photosynthetic efficiency and plant growth. These findings will be useful for improving salt tolerance of peanuts.
