“…1). Growth response to salinity in this study is consistent with our previous observation in which the growth of A. pseudoalhagi was enhanced by a moderate level of NaCl application (Kurban et al 1998). Similarly, the CO 2 assimilation rate and the stomatal conductance in the 50 mM treatment were significantly higher than in the control.…”

“…5). Chloride probably behaved in the same way as Na+ because the uptake of the two ions is very sirriilar in A. pseudoalhagi (Kurban et al 1998). In spite of the accumulation ofNa+ and Cl-, growth and development of A. pseudoalhagi were slow but continued in the 200 mM treatment (Fig.…”

“…This arises from the inhibition of nutrient uptake through competitive interactions or by affecting the ion selectivity of membranes, resulting in effects such as salinity-induced calcium ion (Ca 2+ ) and/or potassium ion (K + ) deficiencies (Ruiz et al 1997;Kurban et al 1998;Kudo et al 2010) and Ca 2+ -induced magnesium ion (Mg 2+ ) deficiencies (Grattan and Grieve 1999). This deficiency often results in high ratios of Na + /Ca 2+ and Na + /K + , which may reduce plant growth (Ruiz et al 1997).…”

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.

“…Estes resultados também reforçam a necessidade de que estudos sobre estresse salino sejam também analisados levando-se em conta o desenvolvimento morfofi siológico das plântulas (Sousa et al 2004). De modo geral, os resultados aqui apresentados foram similares aos observados por outros autores (Jolivet et al 1990, em Triticum aestivum; Lutts et al 1995, em Oryza sativa; Kurban et al 1998, em Vigna radiata; Lovato et al 1999, em Stylosanthes humilis; Ruiz et al 1999…”

ABSTRACT(Salt stress delays morphophysiological development and activation of cell wall galactosidases in Vigna unguiculata stems). In order to examine the participation of α-and β-galactosidases in the cell expansion of stems from cowpea seedlings submitted to salt stress during plant establishment as well as to analyze the eff ect of salt stress on the development of seedlings and enzymatic activities, Pitiúba cowpea seeds were sown in distilled water and in 100 mM NaCl. Th roughout seed germination and seedling development, stems were harvested from seedlings at diff erent stages of development and at diff erent times aft er planting. Growth was evaluated by measuring stem length and fresh and dry mass of stems. Salinity both inhibited and delayed the growth of seedling stems. Th e eff ects of NaCl on galactosidase activities of the cell wall were studied, both in vivo and in vitro. Galactosidase activities in vivo were related to eff ects of NaCl inhibition and delay of stem development. Th e increase in salt concentration inhibited isolated galactosidase activity of cell wall from stems of seedlings. Starting at 250 mM NaCl, β-galactosidases were more sensitive to salt than α-galactosidases.
