To cite this paper: Kausar, F. and M. Shahbaz, 2017. Influence of strigolactone (GR24) as a seed treatment on growth, gas exchange and chlorophyll fluorescence of wheat under saline conditions. AbstractStriglactones are generally considered as the signaling molecules. A pot experiment was conducted to explore the role of strigolactone (GR24) as seed treatment on wheat under saline conditions. Seeds of two wheat cultivars (S-24 and PARI-73) were sown in sand. Two salt treatments [control (non-saline) and 150 mM (NaCl)] nourished with full strength Hoagland's nutrient solution were applied as root growing medium while four strigolactone (GR24) levels (water (0), 0.001, 0.01 and 0.1 mg L -1 ) were applied as seed treatment for 16 h. Imposition of salt stress significantly reduced growth attributes while plants developed from seeds raised with GR24 showed variable response on growth under salt stress. Pre-sowing seed treatment with GR24 showed non-significant effect on shoot fresh and dry weight and root length. Net CO2 assimilation rate of both wheat genotypes increased due to GR24 application. In chlorophyll fluorescence plants showed increasing response towards application of GR24 with respect to co-efficient of photochemical quenching (qN) and non-photochemical quenching (NPQ) under non-saline. Root-medium salinity significantly enhanced the concentrations of Na + ions and decreased K + ions in shoot and roots. Pre-seed treatment with GR24 did not modulate concentration of shoot and roots Na + and K + ions. Overall, the wheat cultivar S-24 showed better performance for growth parameters and non-significant behavior towards the photosynthetic rate. Both the cultivars showed uniform response in chlorophyll fluorescence.

“…Plants deficient in α-tocopherol exhibit deprived germination, poor seedling growth, impair photo-assimilate translocation and accelerate leaf senescence (Sattler et al, 2004(Sattler et al, , 2006. Adverse effects of salt stress on growth of various plant species have been studied (Shahbaz and Ashraf, 2013;Masood and Shahbaz, 2016;Kausar and Shahbaz, 2017). On the contrary, there is little acquaintance about role of alpha tocopherols in improving salinity tolerance in plants.…”

Among abiotic stresses salinity is one of the serious threats for food security worldwide. Sunflower is ranked 5 th among crops grown for food security and being moderately salt tolerant is a better choice for growing on saline soil. Application of various compounds including vitamin E might be a beneficial technique for improving growth in plants under saline conditions. A pot experiment was conducted to explore the role of alpha tocopherol seed treatment for inducing salt tolerance in sunflower. Seeds of two sunflower cultivars (FH-572 and FH-621) were soaked for 16 h in four levels of alpha tocopherol i.e. control (distilled water), 100, 200, 300 mg L-1 and two levels of NaCl salt (0 and 120 mM) were applied with full strength Hoagland's solution 35 days after seed sowing. Salt stress caused significant decrease in shoot and root fresh weight, leaf relative water content and inhibition in shoot length. Salinity stress increased leaf turgor potential and had non-significant effect on photosynthetic pigments, osmotic potential and gas exchange characteristics. Seed treatment with α-tocopherol considerably increased shoot and root fresh weight, shoot length, net CO2 assimilation rate, stomatal conductance (gs) and water use efficiency; however, it showed non-significant effect on photosynthetic pigments, leaf water relation parameters and transpiration rate. Alpha tocopherol, 100 and 300 mg L-1 levels were effective in ameliorating the negative impact of salt stress in cv. FH-572 and cv. FH-621, respectively. Results depicts great varietal difference in salinity tolerance and cultivar FH-621 performed better than cv. FH-572 under salinity stress.
