Total protein was quantified in cotyledons at 3, 6 and 9 days after sowing. However, the relative importance of osmotic and specific ion effect on plant growth seems to vary depending on the salt tolerance of the plant under study. 7 (1): 35-44, 2018 (June)The response of BARI Sunflower-2 ( Helianthus annuus L.) to sodium chloride (NaCl) at germination and early seedling growth was investigated. Water chloride concentrations up to 70 ppm are safe for all plants. The results showed that the highest salinity concentration (200 mM NaCl) remarkably decreased the germination percentage, germination index and speed of germination of BARI Sunflower-2. On the other hand, Bronco was relatively, sensitive to salinity in relation to both germination and seedlings characters. Dry weight of root was observed 50.87% at 100, mM NaCl salinity and up to 200 mM NaCl salinit, root is an indication of higher root dry weight. Fe application, particularly in its ferrous form, Resumo: O objetivo deste trabalho foi analisar e descrever a influência da salinidade sobre a germinação e crescimento de Brassica napus L.var (Canola). © 2008-2021 ResearchGate GmbH. measured at the end of the 14th day after sowing. Plants exposed to higher concentrations of sodium chloride were shorter than those exposed to lower concentrations (Fig. prevents the plants from taking up the proper balance of nutrients require for healthy growth. Palavras-chave: salinidade, biodiesel, brassica napus L.var. On the other hand, the noticed decrease in the length of the stem, also due to treatment with sodium chloride solution, could be due to the negative effect of this salt on the rate of photosynthesis, the changes in enzyme activity (that subsequently affects protein synthesis), an… The major inhibitory effect of salinity on plant growth and development had been attributed to osmotic inhibition of water availability, toxic effects of salt ions responsible for salinization and nutritional imbalance caused by such ions but the specific effects of soil salinity largely differ depending … Fe supply in a saline environment increases Na levels with increasing salinity, decreases these levels in relation to the control treatment. The results showed that high salinity (200 mmol) remarkably inhibited the germination of seed and delayed germination time in sunflower. Concentrations of 100 and 200 mmol also caused a clear reduction in tissues water content. counteracted the effects of salinity on germination and growth; this effect was more important at higher salinity levels. If sodium or chloride levels are high to excessive in the growing medium, it is most likely coming from the water. In none of the cultivars used in this experiment was it possible to obtain fully developed seedlings at 250 and 350 mM NaCl concentrations. 62,199. The results showed that germination In contrast, the cotton reproductive growth parameters were higher for elevated NaCl and Mn concentrations in irrigation water. At the first and second counts of the germination test, normal seedlings were counted, measured, weighed and dried, supplying data for vigor, total germination, fresh matter weight and dry matter weight and seedlings length. Based on, electrical conductivity of 0-0.75 dS/m has no effect on most plants. Conversely, seedlings were differently affected by treatments in respect to salt type and concentration. An increase was observed in the protein content in the two measurement periods due to the impact of salinity stress. Growth and ion uptake of several varieties ofHordeum during and after sodium chloride treatment. Dantas, B.F., De Sa Ribeiro, L. and Aragao, C.A. The height of each plant was measured weekly. O2 concentrations of the solution elicited the expected responses. Sodium arsenite and NaCl significantly affected macronutrients allocation within bean plant at concentration levels used in this study. The speed of germination may hav, index and germination speed of BARI Sunflower-2, earlier by several workers (Javed & Kha, that shoot growth was more sensitive to salinity, Table 2. Arsenite depressed K, Na, and Mg concentrations in root, whereas root N, and Ca levels were increased. Thus the present study concluded that the BARI Sunflower-2 could be cultivated in moderately saline soil. Analysis of variance of leaf weight changes shows significant difference (F = 68.878) between groups. Results showed that from T1 to T4 soybean performed quite good as compare to the rest of the treatments. Papaya, although exhibits different sensitivities to salinity, has great potential to be cultivated in semi-arid regions of Lara State, Venezuela. The delay in germination has been reported under salinity by many workers in different species (Fancois et al., 1986;Mondal et al., 1988;Karim et al., 1992;Khan et al., 1984;Khan et al., 1997; ... Of cultivar studied, PLG-119 and HGS-18 were found relatively salt tolerant. 1, Talia, P., Greizerstein, E.J. The effect of sodium chloride on general morphometrical parameters of seedlings, and biochemical parameters in the leaves of corn seedlings was studied. Effect of Sodium chloride (NaCl) on germination, growth and yield of Pea plant (Pisum sativum L.) 1*Fiza khan, 2Gulafshan, 3Farha Rahman, 4Hira khan, 5Ruhi khan & 6Noor Fiza 1Department of Botany 1Mohammad Ali Jauhar University Rampur U.P. Na+ and Cl- are among the more common ions found in excess in Effects on plant height and total dry weight were evident after 2 wk of treatment. In plants it can impair their ability to even uptake adequate moisture. Moreover SOME EFFECTS OF SODIUM SALTS ON THE GROWTH OF … Timing of the application of Ca was critical. While sodium is not absorbed by plants, chloride is. Effects of Sodium Chloride Applications and Different Growth Media 1657 ORDER REPRINT S Exposure of 1000mg/L NaCl also caused 1st degree injury in plants in both growth media. However, it will not grow well under a high saline level. We evaluated the effects of seawater and different salts on seed germination, seedling emergence and the antioxidative pathway of quinoa. Concentrations of the NaCl solutions employed in this experiment were 0, 50, 150, 250 and 350 mM. Some effects of variation of the sodium chloride content of the medium on growth, metabolism, and chemical composition of HeLa cells were determined. Efeito da salinidade no desenvolvimento inicial da canola (Brassica napus L.var). U, mass compared to salt susceptible variety, Ashraf, M.Y., Akhtar, K., Sarwar, G. and Ashra. The positive correlation of dry matter yield with sulfur (r=0.93), potassium (r=0.99) and calcium (r=0.83) were observed, whereas sodium had negative relationship (r=-0.99) with dry matter yield. Higher salinity levels hada negative effect on germination that seeds did not germinate at 80 mM and above concentrations of NaCl in Triginellafoenum-graecum, This study was conducted to investigate the NaCl impacts on germination and emergence The mean heights for plants exposed to NaCl were: An efficient antioxidant mechanism was present in quinoa, activated by salts during germination and early seedling growth, as shown by the activities of antioxidant enzymes. To study the effect of salt (NaCl) on root elongation we developed a device that measures this effect by means of a Linear Salinity also reduced the specific leaf area and leaf weight ratio, which indicates that leaf expansion and carbon allocation were altered.
