  Seeds of medicinal plant Artemisia sieberi were pretreated with H2O2 (0, 10, 50, 90, and 140 µM) and grown in saline condition (0 and 150 mM NaCl) for one month. Phytochemical properties such as antioxidant capacity and also salt tolerance in the plans arising fro چکیده کامل

  Seeds of medicinal plant Artemisia sieberi were pretreated with H2O2 (0, 10, 50, 90, and 140 µM) and grown in saline condition (0 and 150 mM NaCl) for one month. Phytochemical properties such as antioxidant capacity and also salt tolerance in the plans arising from H2O2 pretreated seeds under salt stress were examined. Results showed a decrease in H2O2 and malondialdehyde concentrations in the shoots of pretreated A. sieberi. Furthermore, seed pretreatment with H2O2 (particularly at 50 µM) increased photosynthetic pigments content, antioxidant capacity and dry and fresh weights of shoots in the pretreated plants under both normal and saline conditions. The activity of the antioxidant enzymes increased in all pretreated A. sieberi plants particularly at 50 µM H2O2. Data indicated H2O2pretreatment can induce salt tolerance in A. sieberi by supporting physiological and phytochemical processes such as photosynthesis, reactive oxygen species scavenging and detoxification, and also membrane stability in this species. Additionally, hydrogen peroxide pretreatment enhanced reducing power and antioxidant activity in A. sieberi suggesting an increase in its medicinal properties. پرونده مقاله

  In the turfgrass industry, the need for salinity tolerant turfgrasses is increasing because of the increased use of saline and non-potable water. Greenhouse container experiments were conducted to determine the relative salinity tolerance and growth responses of eleven native populations of tall fescue (Festuca arundinacea Schrub) (TF), including: Semirom, Mashhad, Sanandaj, Yasuj, Yazd Abad, Daran, Kamyaran, Gandoman, Borujen, Nasir Abad and Alborz to 8 weeks of salinity stress. Also, commercial TF was usedas control. Four salinity levels of irrigation water (0, 45, 90, 135 mM NaCl) were applied to turfgrasses. Results showed shoot and root dry weight, total leaf area, leaf length, leaf width and leaf firing percentage was significantly affected by salinity for all turfgrasses. The lowest leaf firing percentage at 90 and 135 mM, was related to Sanandaj population and commercial TF, and the highest leaf firing percentage was related to Alborz at 45 mM and Gandoman population at 90 and 135 mM. Shoot dry weight, total leaf area and leaf length of Sanandaj population was less affected by salinity compared to other populations. Based on data on growth parameters, the salinity tolerance ranking of selected populations was: Sanandaj >Daran >Yasuj>Kamyaran >Nasir Abad >Semirom >Mashhad >Alborz >Yazd Abad >Borujen >Gandoman . These results showed the potential and competetive role of TF native populations compared to commercial TF. پرونده مقاله

  Salinity is a significant ecological stressor that reduces agricultural productivity and sustainability in arid and semiarid regions by impacting germination rates, delaying the start of germination, and ultimately delaying seedling establishment. Globally, salt has a negative impact on agricultural yield, because most of cultivated plants are salt-sensitive glycophytes. Salt stress also influences seed germination and seedling establishment in three different ways: ion toxicity, oxidative stress, and osmotic stress. Four groundnut genotypes (KDG-128, GG-20, GJG-31, and TG-37A) were examined for their phenotypic variation and the impact of salt content on germination, growth, and yield metrics. Different KCl and Na2SO4 solution concentrations were used in saline treatments. Salinity had a serious influence on germination, according to the results. Finding salt tolerance genotypes was the main goal of this study. The TG-37A and GJG-31 genotypes were proven to be salt-tolerant based on the germination %, but the KDG-128 genotype is a moderately salt-tolerant genotype and the GG-20 genotype is a salt-susceptible genotype. Genotypes for tolerance are beneficial in the field of agriculture, and the findings unambiguously showthat salinity cannot restrict plant growth and development. پرونده مقاله

  4 - Growth and Chemical Composition of Pistachio Seedling Rootstock in Response to Exogenous Polyamines under Salinity Stress

  In order to evaluate responses of a pistachio seedling rootstock (Pistacia vera L. cv. Ghazvini) to NaCl induced salinity stress and potential protective role of exogenous spermine and spermidine on NaCl induced salinity stress, a greenhouse experiment was conducted dur چکیده کامل

  In order to evaluate responses of a pistachio seedling rootstock (Pistacia vera L. cv. Ghazvini) to NaCl induced salinity stress and potential protective role of exogenous spermine and spermidine on NaCl induced salinity stress, a greenhouse experiment was conducted during growing season of 2009. The NaCl treatments, involving 800, 1600, and 3200 mg NaCl per Kg of soil for 90 days, suppressed growth of the seedlings and induced accumulation of Na+ and Clin roots and shoots. Accumulation of Na+ and Clin shoots was higher than in roots. Our data also showed more accumulation of K+ in the shoot than in the roots under salinity stress. The ratio of K+ /Na+ in compare with control was highly significant in the shoots of stressed plants. Exogenous polyamines (PAs) prevented the growth reduction induced by salinity stress and reduced transport of Na+ and Clfrom the root to shoot and increased translocation of K+ from the root to the shoot of pistachio seedlings. We concluded that ‘Ghazvini’ rootstock appear to be a valuable seedling rootstock with a level of salt tolerance about 1600 mg NaCl Kg-1 Soil. It also concluded that application of exogenous PAs may protect pistachio seedlings from salinity stress effects. پرونده مقاله
