“…This phenomenon could best be explained by salt induced stress since increasing NaCl levels have tendencies of decreasing water absorption into the cells of plants thereby causing physiological desiccations. This is in agreement with the findings of Abbas and Latif (2005) who established a decrease in the growth of jute seedlings under NaCl stress, which they attributed to low water absorption into cells as the salinity increased.…”

Salinity refers to the salt content of any given system. By nature, arid soils are naturally saline. Soils could also acquire salinity due to some agricultural practices like irrigation. There is need therefore for search on halophytes that could adapt to such soils and be used to reclaim soils contaminated with salts. Thus, this present study focused on investigating Amaranthus hybridus and Celosia argentea with respect to their potentials and suitability for use in saline environments. This study was conducted in two phases; germination (laboratory-based) and seedling tests (field-based). Shoot length, root length, root/shoot ratio, total length, fresh weight, dry weight, dry matter content, leaf area index, leaf number as well as relative water content were parameters used for assessing results for the field-based test. Germination results showed that only the control (0 mM) showed 100 % germination in both species. Germination percentages decreased steadily with increasing NaCl concentrations in both species. Growth was steadily stimulated in both species at lower NaCl levels with best growth stimulation at 50 mM NaCl but was adversely affected by higher NaCl concentration levels (75, 100 and 150 mM). Both species showed almost the same phenomenon for fresh weight, dry weight, dry matter, leaf area index, number of leaves as well as relative water concentration. These show that both species would best be cultivated under moderate than low or high saline concentration. The findings in this study showed that it is best for seedlings of both species of plants to be raised in nurseries free of NaCl to attain 100% germination and after which, the seedlings could then be transplanted to moderately saline soils for maximum growth and development. This has strong implications for maximizing food productivity and ensuring food security.

Los cultivos de células vegetales son sistemas experimentales homogéneos altamente controlables que permiten el estudio de adaptaciones bajo condiciones de estrés hídrico, sin la interferencia de los diferentes tejidos y estados del desarrollo vegetal. Una aproximación para comprender esas adaptaciones, es la aparición de proteínas inducidas, resultado de la alteración en la expresión génica. El presente trabajo analizó la respuesta de cultivos de células de Fouquieria splendens ssp. breviflora, expuestos a ácido abscísico (ABA), mediante la caracterización electroforética en cantidad y calidad de las proteínas inducibles de estrés. Se registraron polipéptidos de bajo peso molecular (< 35KDa), comunes bajo la exposición a 10 mM, seguida la asociación con 20 y 30 mM de ABA, quedando aislada la respuesta de la condición de células en cultivo sin la presencia de éste.

Abstract:The environmental stress such as salinity of soil or water is serious threat for field crops in the world, especially in arid and semiarid regions. To study salinity stress on jute (Corchorus capsularis), an experiment was laid out in factorial randomized block design keeping nine capsularis varieties (JRC-698, JRC-321, JRC-517, JRC-7447, JBC-5, JRC-212, JRC-80, JRC-532 and UPC-94) as one factor and four levels of salt concentrations i.e. control (Distilled H 2 O), 100, 160, 240 and 300 mM NaCl with three replications. Adverse effect of salinity increased with increasing concentration of sodium chloride. Among nine jute varieties the highest germination percentage (89.5%), root length (0.6 cm), shoot length (1.2 cm), fresh weight (93 mg) and dry weight (9.5 mg) of seedling were observed in 'JRC-698' at salt concentration at 160 mM NaCl as compared with other salt concentration. All growth parameters were recorded higher in control than other treatments. All growth parameters were decreased up to 240 mM NaCl concentration and it was completely inhibited at 300 mM NaCl. Variety 'UPC-94' was the most susceptible to salinity stress. Hence, white jute varieties, JRC-698 and JRC-517 can be grown at 160 mM NaCl concentration.
