“…The accumulation of salts can be due to the increase of the evaporation rate near the soil surface in the case of DI (Hachicha et al, 2006). Adverse effects observed on chlorophyll contents of the three cultivars, under salt stress, have previously been shown in rice (Yeo et al, 1990), bareley (Belkodja et al, 1994), tomato (Kaya et al, 2001) and Shinopsis quebracho colorado (Meloni et al, 2008). The present study shows a significant increase in Na + and Cl -with the water deficit treatment (70% of water requirement) for the three cultivars (Table 3).…”

A field experiment on the effects of drip irrigation (DI) and subsurface drip irrigation (SDI) with saline water (6.57 dS m -1 ) on three tomato cultivars (Lycopersicon esculentum Mill., cvs. Río Tinto, Río Grande and Nemador) was carried out with the purpose to quantify physiological responses. The aim was to improve irrigation water management under saline conditions of Tunisia. The trial was established in a siltclayey soil with three regimes of irrigation: 100 %, 85 % and 70 % of crop water requirement. Results evidenced a significant difference between the two irrigation systems for the three cultivars. Growth parameters such as leaf area, chlorophyll content and mineral composition of leaves, petioles, stems and roots were affected significantly by the different treatments, particularly for Río Tinto and Nemador, being Río Grande the more adapted. The fruit was the organ less affected. Strong accumulation of Na + and Cl -accompanied a reduction in Ca 2+ , K + , Mg 2+ and P content in the case of DI. The distribution of these last necessary elements for plants nutrition under a strong accumulation of Na + and Cl -depends on the cultivar and changes from one organ to another. SDI can be included as an effective option for tomato production in Tunisia.

“…Furthermore, when salts are present in the soil solution, they cause nutrient imbalances, inducing inhibition in the uptake of essential nutrients from the roots [107][108][109][110]. Other consequences of salt stress include metabolism alteration, such as hormonal changes, reduced enzyme activity and impaired photosynthesis [10,111].…”

This review deals with the adaptive mechanisms that plants can implement to cope with the challenge of salt stress. Plants tolerant to NaCl implement a series of adaptations to acclimate to salinity, including morphological, physiological and biochemical changes. These changes include increases in the root/canopy ratio and in the chlorophyll content in addition to changes in the leaf anatomy that ultimately lead to preventing leaf ion toxicity, thus maintaining the water status in order to limit water loss and protect the photosynthesis process. Furthermore, we deal with the effect of salt stress on photosynthesis and chlorophyll fluorescence and some of the mechanisms thought to protect the photosynthetic machinery, including the xanthophyll cycle, photorespiration pathway, and water-water cycle. Finally, we also provide an updated discussion on salt-induced oxidative stress at the subcellular level and its effect on the antioxidant machinery in both salt-tolerant and salt-sensitive plants. The aim is to extend our understanding of how salinity may affect the physiological characteristics of plants.

“…In such regions, germination and seedling establishment constitute the most critical periods in the life-cycle of plants (Meloni et al 2008). The process of germination commences with absorption of water (Wahid et al 1998, Zehra et al 2012) and finishes with the emergence and elongation of embryonic tissues.…”

Festuca ovina L. is an important ornamental species used in urban landscapes and pastures reclamation. However, low resistance of this species to salt stress has hindered its extended application in low-water and salty regions. To study the effects of calcium on reducing salt stress injuries in seed germination and early growth of this species, a factorial experiment based on completely randomized design with three replications was conducted. The salt levels included NaCl solutions (5, 10, 15 and 20 dS/m). Calcium source was CaCl 2 with concentrations of 0, 10, 20 and 30 mmol + /L. Germination percentage and mean germination time were significantly affected by interaction of salinity and calcium. As salinity increased, mean germination time increased. However, germination percentage, shootlet length, rootlet length, shootlet fresh and dry weight, rootlet fresh and dry weight and seed vigour index decreased following the increasing salinity. Concentrations of 10 and 20 mmol + /L CaCl 2 had significant effects on reducing salt injuries on seed germination of Festuca ovina. This finding was even prominent in higher salinity levels of 15 and 20 dS/m. Therefore, to facilitate using this species in urban landscapes or in pastures, pre-treatment of the seeds using 10 and 20 mmol + /L CaCl 2 is recommended.
