“…In a previous in-vitro experiment with CAB-6P explants treated with 60 mM NaCl, one of the main effects of the high leaf Cl concentration (4.2-5.6 % d.w.) was the decline in chlorophyll concentration of leaves (Chatzissavvidis et al 2008). Similarly, in another study with Prunus salicina, leaf chlorophyll concentration decreased when leaf chloride exceeded 0.25 mol kg -1 d.w. (about 0.9 % d.w.) (Ziska et al 1990).…”

“…It is also well documented that various Prunus species are included in the group of salt sensitive species (Andreu et al 2011). Although, there are many published papers dealing with the effects of salinity on growth, antioxidants, photosynthesis, nutritional status and several other parameters of Prunus species (Ziska et al 1990, Papadakis et al 2007, Chatzissavvidis et al 2008, Andreu et al 2011, there are no detailed studies regarding the changes and/or possible adaptations occurring just after exposure to saline environments. Such data would add valuable information to our knowledge about the initial events that take place during the exposure of fruit trees to salinity.…”

Running title: Salinity stress response in Prunus cerasusAbstract -The gradual response of CAB-6P sour cherry (Prunus cerasus L.) plants to NaClinduced salinity stress (60 mM NaCl) was investigated in a short-term hydroponic experiment, based on parameters relating to the growth, water relations, chlorophyll and mineral nutrition. The results showed that CAB-6P plants are very sensitive to salinity stress because their growth and leaf chlorophyll concentration were both affected negatively from the 3 rd and 5 th day, respectively, after incurring salinity stress. Since root growth was suppressed more severely than shoot growth, the shoot to root ratio was significantly increased under saline conditions. The concentrations of Na in leaves and stem of NaCltreated plants were much lower than those measured in roots, suggesting Na exclusion mechanism from the shoot. The opposite trend was observed for Cl, indicating Cl inclusion mechanism to leaves. As regards the concentrations of Ca, Mg, P, K, Na, Fe, Zn and Mn, they were not changed in higher salinity conditions, apart from K, concentrations of which in leaves and roots were significantly increased and decreased, respectively (K translocation to leaves). Salinity further reduced K/Na ratio in root and stem as well as leaf water and osmotic potentials, whereas leaves of control and NaCl-treated plants presented similar turgor potential and K/Na ratio. These data add very important information to our knowledge about the physiological events occurring in sour cherry plants after even short-term exposure to salinity.

“…In Prunus cerasus cv. CAB-6P rootstock leaves, POX-3 isoenzyme band appeared under different concentrations of NaCl and CaCl2, but POX-4 isoenzyme band were detected highest in NaCl concentration (60 mM), and both 30 and 60 mM CaCl2 concentrations (Chatzissavvidis et al, 2008). Radić et al, (2006) reported that in Centaurea regusina L., all NaCl and mannitol treatments induced POX-3 and POX-4 isoenzymes but POX-9 appeared only in response to high NaCl concentration.…”

“…It is well established that salinity stress is followed by chlorophyll degradation that leads to a chlorotic appearance in explants. High concentrations of NaCl applied under in vitro conditions reduced the chlorophyll content in Citrus (PEREZ-TORNERO et al 2009) and other woody species (CHATZISSAVVIDIS et al 2008). Similarly, GHALEB et al (2010) experimenting with sour orange cultivated under in vitro conditions recorded complete leaf damage at 300 mM NaCl.…”

-The effect of continuous or gradual stress due to NaCl on in vitro growth, proline and sugar accumulation and nutrient acquisition of trifoliate orange (Poncirus trifoliata (L.) Raf.) explants was studied. Apical shoot tips obtained from previous subculture were transferred to a Murashige and Skoog nutrient medium for proliferation and were exposed to continuous or gradual salinity stress for 42 days. The salt used to induce salinity was NaCl added in six concentrations: 0, 50, 100, 150, 200 and 300 mM. Gradual salinization was achieved by transferring the explants sequentially every week to the above mentioned NaCl concentrations. Most salt treatments had a negative effect on the growth parameters of explants. Sodium concentration of explants increased in all NaCl treatments compared to control and it was higher in the treatments with gradual exposure to salinity. Potassium concentration was reduced, mostly in the treatments with continuous exposure. Calcium and Mg concentrations increased in all saline treatments. In general, the high salinity level in the substrate enhanced the proline and sugar concentrations of the studied explants. In conclusion, salinity had significant impacts on the growth and chemical status of P. trifoliata.
