“…These include what regulates the dichotomy between stress adaptation and growth inhibition under stress (Golldack, Li, Mohan, & Probst, ; Mickelbart, Hasegawa, & Bailey‐Serres, ). Although there is a clear and well documented correlation between overexpression of adaptation traits and growth reduction (Maggio, Matsumoto, Hasegawa, Pardo, & Bressan, ; Munns & Gilliham, ), there are also a few examples in the literature indicating that best performers under stress are those that have a reduced perception of the stress and, therefore, grow relatively well in the presence of moderate root zone salinity (Barbieri et al, ; Mancarella et al, ; Orsini, Alnayef, Bona, Maggio, & Gianquinto, ). Ocimum basilicum cultivars are grown globally with a large number that vary in morphology, secondary metabolites and flavour (Hiltunen & Holm, ).…”

“…Two genotypes of basil, predominantly used in Italy (Barbieri et al, ; Raimondi, Orsini, Maggio, De Pascale, & Barbieri, ), Napoletano (NAP) and Genovese (GEN) have differing morphologies, flavour and, most importantly, tolerance to salinity. Previously, these two genotypes were assessed for their salinity tolerance and NAP was found to be much more sensitive to salinity than GEN (Barbieri et al, ; Mancarella et al, ).…”

Omeprazole (OP) has been shown to act as a plant growth regulator and enhances tolerance to salt stress. In this study, two Ocimum basilicum genotypes were tested for their responses to OP under salt stress. The two genotypes, Napoletano (NAP) a salt sensitive genotype, and Genovese (GEN) a salt tolerant genotype, had contrasting responses to OP treatment. NAP demonstrated increases in terms of growth (+36%) and salt tolerance (+19%) upon treatment while GEN had a growth increase (+35%) and OP enhanced sensitivity to salt stress (−13%). OP treatment also had an effect on the post-harvest behaviour of these two genotypes by increasing NAP shelf life while decreasing GEN shelf life. The contrasting responses to OP in these two genotypes has provided insight into the role of this molecule in mediating growth and adaptation to stress and, more importantly, into the complexity of the mechanisms mediating these processes.basil, benzimidazole, omeprazole, PPI, proton pump inhibitor, salt stress Abbreviations: DAS, days after sowing; DAST, days after stress treatment; GEN, Genovese; LEA, late embryogenesis abundant; NAP, Napoletano; OP, omeprazole; PPI, proton pump inhibitor; ROS, reactive oxygen species; RWC, relative water content; SDW, shoot dry weight; SFW, shoot fresh weight. † These authors contributed equally to this study.

“…When analyzing the correlation between the chlorophyll content variables, it was observed that the highest positive correlation was obtained between F m and F v (0.98) and the negative between F 0 and F v (0.66). In accordance to Mancarella et al (2016), by measuring the chlorophyll fluorescence it is possible to diagnose the state in which the plant is located, besides obtaining information for a clarification of a cause and effect relationship between the mechanisms controlling the water balance and plant growth.…”

It is estimated that more than 900 million hectares of the world's arable land are affected by salinity (Mancarella et al, 2016). Salinity is caused mostly by weathering processes on rocks, irrigation with high soluble ions concentration water, and fertilizer applications.…”

Basil (Ocimum basilicum L.) is one of the world's most widely cultivated medicinal herbs, but its physiological processes are affected by salinity. Therefore, mitigation strategies against the harmful effects of salt on plants have been increasingly on demand, including the use of salicylic acid. Thus, the effect of salicylic acid on the ecophysiology of basil plants grown under saline stress was evaluated in two different periods. The experimental design was the randomized complete block design using the Box Central Composite matrix with five irrigation water electrical conductivities (0.5, 1.3, 3.25, 5.2, 6.0 and dS m -1 ) and five doses of salicylic acid (0.0, 0.29, 1.0, 1.71 and 2.0 mM), with five replicates. Gaseous exchanges, fluorescence and chlorophyll content were evaluated at 30 and 60 days after irrigation with saline water started. Data were evaluated by analysis of variance and regression and by correlation analysis. The water electrical conductivity negatively affected the analyzed variables, while the salicylic acid had a positive effect. The highest correlation between the variables was obtained at 30 days after the irrigation with saline water started. Salicylic acid treatment up to the dose of 1.0 mM has a beneficial effect on basil plants. Aspectos ecofisiológicos deOcimum basilicum sob estresse salino e ácido salicílico RESUMO: Manjericão (Ocimum basilicum L.) é uma das ervas condimentares e medicinais mais cultivadas no mundo, porém, seus processos fisiológicos podem ser afetados pela salinidade. Contudo, é uma demanda crescente a busca por estratégias que mitiguem os efeitos nocivos dos sais às plantas, e dentre estas, está o ácido salicílico. Com isso, avaliou-se o efeito mitigador do ácido salicílico na ecofisiologia do manjericão submetido ao estresse salino em dois períodos de avaliação. O delineamento utilizado de blocos casualizados, utilizando a matriz composto central de Box com cinco condutividades elétricas da água de irrigação (0,5; 1,3; 3,25; 5,2; 6,0 e dS m -1 ) e cinco doses de ácido salicílico (0,0; 0,29; 1,0; 1,71 e 2,0 mM), com cinco repetições. Foram avaliadas as trocas gasosas, fluorescências e índices de clorofilas aos 30 e 60 dias após a irrigação com água salina. Os dados foram avaliados por análise de variância e de regressão e por análise de correlação. A condutividade elétrica da água afetou negativamente, enquanto o ácido salicílico afetou positivamente as variáveis analisadas. A maior correlação entre as variáveis foi obtida 30 dias após o início da aplicação das águas salinas. O ácido salicílico possui efeito benéfico em plantas de manjericão até a dose de 1,0 mM.
