“…It is known that prolonged salt stress may cause changes in leaf anatomy (Garrido et al, 2014;Fernández-García et al, 2014). The observed morphological changes at 30 days of stress (increased root/canopy ratio) in S8 plants were accompanied by leaf anatomical changes.…”

Physiological and biochemical changes in Myrtus communis L. plants after being subjected to different solutions of NaCl (44, and 88 mM) for up to 30 days (Phase I) and after recovery from the salinity period (Phase II) were studied. Myrtle plants showed salinity tolerance by displaying a series of adaptative mechanisms to cope with salt-stress, including controlled ion homeostasis, the increase in root/shoot ratio, the reduction of water potentials and stomatal conductance to limit water loss. In addition, they displayed different strategies to protect the photosynthetic machinery, including limiting toxic ion accumulation in leaves, increase in chlorophyll content, and changes in chlorophyll fluorescence parameters, leaf anatomy and increases in catalase activity. Anatomical modifications in leaves, including a decrease in spongy parenchyma and increased intercellular spaces, allow CO2 diffusion in a situation of reduced stomatal aperture. In spite of all these changes, salinity produced oxidative stress in myrtle plants as monitored by increases in oxidative stress parameter values. The post-recovery period is perceived as a new stress situation, as observed through effects on plant growth and alterations in non-photochemical quenching parameters and lipid peroxidation values.

Garrido et al [18] evaluated physiological, phytochemical, and structural changes in lettuce by salt stress in a soilless system. In Korea, land constructed by land reclamation projects was mainly used to produce paddy rice.…”

Abstract:Since the salinity of irrigation water is a critical constraint to the production of certain vegetable crops, salinity has been considered as one of the most important factors of irrigation water. The objective of this study was to investigate the response of lettuce and Chinese cabbage to various salinity levels of irrigation water in greenhouse cultivation. A pot experiment was conducted with different salinities under a glasshouse condition in Korea. A completely randomized experimental design was used with three replications. The analysis results of crop growth and yield of lettuce and Chinese cabbage indicated that the factors that were more significantly affected by saline irrigation water were crop yields rather than crop components such as number of leaves, leaf length, and leaf width. In this study, the point of salt concentration during an increase in salinity levels of irrigation water (EC w ) at which yield starts to decline was determined to be 0.9 and 1.5 dS/m for lettuce and Chinese cabbage, respectively. Furthermore, the present study demonstrated that the continuous irrigation of saline water under greenhouse conditions could lead to a significant increase in electric conductivity (EC e ) level and Na + concentration in soil, as well as Na + concentration in leaves of crops.

“…Embora o estresse salino afete bastante a produção das plantas de alface, existem relatos que mostram a influência positiva do estresse salino na qualidade pós-colheita da alface, melhorando as propriedades do produto, aumentando a vida útil devido à redução da atividade oxidativa e reduzindo a produção de CO2, bem como a manutenção da cor e da textura das folhas (GARRIDO et al, 2014).…”

IntroduçãoDentre as hortaliças amplamente consumidas no Brasil, a alface (Lactuta sativa L.) pertencente à família das Asteraceae, tem grande destaque na mesa do brasileiro, tanto para uso de saladas como sua ampla utilização em fast-food o que demanda produtos de alta qualidade.Cada vez mais surge a necessidade de se trabalhar o comportamento desta cultura em meio a situações de estresse salino mantendo sua qualidade, uma vez que a utilização de água de boa qualidade para irrigação se torna cada vez mais restrita. Diante disto, para que se tenha um equilíbrio entre o efeito positivo do uso de sal na solução nutritiva no que diz respeito o aumento da qualidade de plantas de alface, bem como, para suprir desequilíbrio iônico de potássio nas plantas afetadas pela salinidade, objetivou-se com este trabalho avaliar o efeito do enriquecimento de potássio na solução nutritiva em plantas de alface submetidas a estresse salino. Fundamentação TeóricaA tolerância à salinidade é variável entre espécies e, mesmo em uma espécie, o efeito do estresse salino é dependente de fatores como estádios de desenvolvimento, fatores ambientais, cultivar, tipo de sais, intensidade e duração do estresse salino, manejo cultural e da irrigação e condições edafoclimáticas (MUNNS, 2005).
