“…It seemed that the seeds harvested 70 daa were capable to generate required osmotic potential to improve the water status of the embryo, permitting protrusion of the primary root better than earlier ones (Hegarty, 1978). Agreeing with these conclusions, Still and Bradford (1998) in cabbage and rape seeds, Welbaum and Bradford (1990) in muskmelon, Demir et al, (2003) in aubergine seeds also found that the immature seeds were more sensitive to the externally applied osmotic potential and salt stresses than that of mature. The seeds that grew at NaCl concentrations had higher seedling fresh weight but lower dry weight than that of PEG in all the harvests (Table 2 and 3).…”

“…The seedling growth, dry weight and emergence in the carrot (Schmidhalter and Oertli, 1991), cucumber (Passam and Kakouriotis, 1994) and aubergine (Demir et al, 2003) have been reported to be more sensitive to the salinity comparing to the seed germination. The salt and osmotic stress inhibited to the seed germination as well as the seedling weight in this work.…”

“…It has been classified as a moderately sensitive plant (Dajic 2006) and most of its cultivars studied have been shown to be affected by salinity stress owing to their inability to control or regulate the uptake and accumulation of Na in the leaves (Chartzoulakis and Loupassaki 1997;Savvas and Lenz 2000;Demir et al 2003;Akinci et al 2004;Unlukara et al 2010;Abbas et al 2010).…”

Solanum scabrum Mill. (huckleberry) is widespread in West, East and Central Africa, where it constitutes one of the most important leafy vegetables. However, the salinity tolerance of this crop has not yet been assessed. The objective of this study was to assess the response of huckleberry to salinity stress in comparison with eggplant (S. melongena L.). Four-week-old seedlings of both species were subjected to two levels of salinity stress, 50 mM and 150 mM sodium chloride (NaCl), for 14 d. Leaf water potential of both species decreased with increasing salinity stress. This decrease was lower in huckleberry than in eggplant. Total dry weight and total leaf area were also decreased by salinity, and the reductions of total dry weight and total leaf area under the 50 mM treatment compared with the control were 25 and 18% in huckleberry, while they were 47 and 55% in eggplant, respectively. The increases in leaf sodium (Na) accumulation in the 50 and 150 mM treatments compared with the control were 65 and 66% for eggplant and 18 and 36% for huckleberry, respectively. Na accumulation in stem and root in huckleberry was higher than that of leaf, whereas it was the reverse in eggplant under both salinity treatments. Huckleberry accumulated less Na in the leaves than eggplant, suggesting that huckleberry might reduce the transport of Na to its leaves more effectively than eggplant. The decrease of potassium (K) accumulation and the increase of Na in leaves by salinity resulted in a higher Na/K ratio in leaves, but this trend was greater in eggplant than in huckleberry. The calcium (Ca) concentration in leaves of huckleberry was also increased by salinity, whereas that of eggplant was decreased. These results indicate that huckleberry is more tolerant to salinity than eggplant, and less decrease in leaf area associated with lower leaf Na and increased Ca concentrations may be important in enhancing quality and sustaining productivity of the crop under this stress.

“…Howewer, the effect mechanism of salinity has not been completely clarified so far (AlKaraki 2001, Ghoulam and Fores 2001). It is well known that salinity prevents seed germination (Chartzoulakis and Loupanak 1997, Hosseini et al 2002, Demir et al 2003 and seedling growth (Dash and Panda 2001, El-Mashad and Kamel 2001, Ashraf et al 2002. The seedling growth and germination of A. cepa seeds, as expected, were inhibited under saline conditions (Table 1).…”

SummaryThe present study was performed to evaluate the role of Aloe vera L. leaf extract (AvLE) on some physiological and cytogenetical parameters of Allium cepa L. seeds exposed to salinity. The radicle length of the seeds germinated in the medium with AvLE alone increased as compared with ones of the control seeds germinated in distilled water medium, while their radicle number and fresh weight reduced according to the control. In addition, the germination percentage of the mentioned seeds statistically was the same as the control seeds. Furthermore, the seeds germinated in the media containing 0.1 mg/L AvLE alone showed a significant increase of mitotic index, although they exhibited a higher number of chromosomal aberrations and micronucleus (MN) formation as compared with the seeds germinated in control conditions. On the other hand, salt stress considerably inhibited the seed germination and seedling growth of A. cepa. Moreover, salinity markedly decreased the mitotic index in root tip meristems of the seeds and increased the number of chromosomal aberrations. The negative effect of salt on the seed germination, seedling growth, mitotic activity and MN formation was alleviated in dramatically varying degrees by AvLE application. In contrast, the detrimental effects of salt on the chromosomal aberrations greatly increased with this treatment. Consequently, we reported that the application of AvLE alone induced chromosomal aberrations and MN formation, which are an indicator of genotoxicity, and had cytotoxic activity in normal conditions. However, the frequency of MN is greatly reduced in root tip cells of the seeds germinated in the medium containing 0.1 mg/L AvLE +0.15 M NaCl.
