“…Also in line with our results, Francois (1996) and Bybordy (2010) reported that seed yield of sunflower and canola cultivars were reduced with increasing salinity level, respectively. Moreover, Hebbara et al (1992) and Hebbara et al (2003), also in line with our results reported that yield of all of sunflower cultivars decreased as salinity levels increased in the field. In the pot experiment, Hebbara et al (2003) showed that leaf temperature, stomata conductance and transpiration rate reduced, but osmotic potential increased under salinity.…”

Seeds of ten sesame cultivars (Karaj, Darab, Safiabad, Jiroft, Borazjan, Yellow-white, Felestin, Ultan, Isfahan and Abpakhsh) were sown into soil filled pots in 2008 and 2009. Pots were watered with six levels of salts (0.0038 (tap water as control), 4.89, 8.61, 10.5, 14.54, 17.74 ds.m-1 NaCl) until full maturity. Plant height, root and shoot dry weight, yield and yield components, seed oil and protein contents of cultivars were measured. Increasing salinity caused significant reduction in plant height, root and shoot dry weight, yield and yield components, seed oil and protein contents of all cultivars. However, there were significant differences among the cultivars for measured traits for each salinity level. Based on seed oil yield data, Safiabad and Kraj at 0.0038ds.m-1, Safiabad and Ultan at 4.89ds.m-1, Ultan, Safiabad and Darab at 8.61 salinity levels were the superior cultivars. High variability in tolerance to salinity among the tested sesame cultivars suggests that selection of more salt tolerant cultivars for planting or breeding purposes is possible.HighlightsEffects of contrasting salinity levels (0.0038 (tap water as control), 4.89, 8.61, 10.5, 14.54, 17.74 ds.m-1NaCl) on sesame cultivars were tested.

Salinity is an obstacle for plant growth and the exploitation of means like cation foliar to soften the negative effects is of interest. The impacts of NaCl salinity (0, 75, 150, and 225 mM) and nano-Zn and Fe foliar applications (0 and 3 mg L −1) were examined on yield and physiological characteristics of Rosmarinus officinalis grown in an open soilless culture system. Salinity decreased root growth and above-ground plant growth (fresh and dry weight), chlorophyll a and total chlorophyll content, and zinc accumulation. Nano-Fe and Zn foliar application had positive influence on the above-ground plant growth. The results showed that Zn 2+ content was affected by the interaction between salinity and nano-Fe and Zn foliar application. The highest content of Zn 2+ was found at no saline Zn-sprayed plants. The content of Zn 2+ , hydrogen peroxide (H 2 O 2), malondialdehyde (MDA), and phenolics were affected by the independent effects of salinity or foliar application. Salinity increased the H 2 O 2 and MDA content but nano-zinc and iron spraying alleviated salinity impacts and both H 2 O 2 and MDA decreased. Nano-Fe and Zn foliar application increased total phenolics and total flavonoids content. Proline and chlorophyll a content, Na + , K + amounts, and K + /Na + ratio were affected by the salinity stress. Salinity decreased K + content and K + /Na + ratio but increased Na + and proline content with more pronounced effects at 225 mM NaCl. Overall, foliar application of both elements improved the growth and salt tolerance of rosemary and their application would be advisable to the cultivation practices.

“…High concentrations of dissolved salts in the soil and root zone can cause the high osmotic pressure and, thus, water availability is reduced. These conditions affect physiological activities and subsequently crop yield since plants will need to spend more energy to obtain water (Hebbara et al, 2003).…”

Abstract:. Aloe vera L. is a perennial liliaceous plant with succulent green leaves, it is a xerophyte with economic and social value, but little is known about its response to salt stress and its mechanisms of tolerance, especially at moderate concentrations. The objective was to investigate the effect of salinity stress (0, 30, 60, 90 and 120 mM NaCl) on Aloe by measuring physiological and morphometric traits related to growth. The results of measuring physiological traits showed no signifi cant differences compared to the control at 30 and 60 mM (chlorophylls a, b, total, relative water content, net assimilation rate, specifi c leaf weight, and specifi c leaf area), even at 90 mM or 120 mM most parameter variations were not signifi cantly different. Similarly, for morphological traits no signifi cant differences were found compared to the control for all 16 morphological traits at 30 mM, or even at 60 mM since at this concentration only one trait varied signifi cantly (1 out of 16). Although the general trend of increasing NaCl was to lower leaf fresh weight as salinity increased, presumably due to a decrease in water content. However leaf dry weight was not signifi cantly reduced at any of the salinity concentrations applied. Thus, total dry leaf biomass was basically the same or similar, this suggesting that Aloe has an ability to withstand these levels of salinity stress. It is noteworthy to point out, that there is a general trend of lower growth (lower parameters both physiological and morphological) that is not signifi cant at low doses (30 and 60 mM), however becoming more signifi cant at higher doses (90 and 120 mM). Thus, we suggest that Aloe has continuum responses to NaCl stress. Keywords: biomass, growth analysis, NaCl salinity salt tolerance.Resumen: Aloe vera L. es una planta liliácea perenne con hojas verdes suculentas, es una xerófi la con valor económico y social; sin embargo, existe poca información disponible en torno a su respuesta a la salinidad y sus mecanismos de tolerancia, especialmente en concentraciones moderadas. El objetivo fue investigar el efecto del estrés salino (0, 30, 60, 90 y 120 mM de NaCl) en rasgos fi siológicos y morfométricos relacionados con el crecimiento de Aloe. Los resultados de las características fi siológicas (clorofi las a, b, total; contenido relativo de agua;, tasa de asimilación neta; peso específi co de la hoja y área foliar específi ca), no mostraron diferencias signifi cativas en 60 y 90 mM, comparados con el control. Incluso en 90 ó 120 mM, la variación de algunos parámetros fue diferente signifi cativamente. Igualmente, para características morfológicas no se encontraron diferencias significativas con respecto al control en las 16 características utilizadas a 30 mM. Incluso a 60 mM solamente una característica difi rió signifi cativamente. Aunque la tendencia general al incrementar la concentración de NaCl fue la disminución del peso fresco de la hoja, presumiblemente debido a la disminución del contenido de agua. Sin embargo, el peso seco de la hoja n...
