“…), cytokinins (e.g., indole butyric acid), thiourea, hydrogen peroxide etc., have been successfully used to improve plant growth under normal or subversive conditions (Gianfagna, 1987;Wahid et al, 2007;Pandey et al, 2013). There are quite a few nitrogen containing growth regulating substances, such as thiourea, that have specifically proven worthwhile in improving crop growth and productivity (Farooq et al, 2009;Perveen et al, 2016). This is attributed to the fact that, in addition to growthregulatory roles, these compounds are metabolized and provide as a source of nitrogen nutrition (Perveen et al, 2015).…”

To cite this paper: Wahid, A., S.M.A. Basra and M. Farooq, 2017. Thiourea: a molecule with immense biological significance for plants. Int. J. Agric. Biol., AbstractThiourea, also chemically named as Thiocarbamide, is a nitrogen and sulfur containing compound. It has three functional groups, amino, imino and thiol, each with important biological roles. Thiourea is being increasingly used to improve plant growth and productivity under normal and stressful conditions. Use of thiourea as seed priming agent, foliar spray or medium supplementation is more effective under environmental stress than under normal conditions. When used as seed pretreatment, thiourea increased the seed germination; while application as foliar spray improved the gas exchange properties and when used as medium supplementation, it improved the root growth and its proliferation. This indicates that thiourea is more effective in the tissues where it is applied. Although to a differential extent, thiourea is effective in improving plant growth and development under drought, salinity, heat stress and heavy metal toxicity. At physiological level, it improves the leaf gas exchange, nutrient acquisition by the root and assimilation thereafter. At biochemical level, exogenously applied thiourea improves the sugar metabolism and enhances the proteins biosynthesis. At molecular level, thiourea application modulates the pattern of gene expression regardless of the stress applied. Signaling of gene expression is a likely mechanism induced by thiourea. In a nutshell, even though considerable advancement has been made in understanding the biological roles of thiourea in modulating different mechanisms in plants, thiourea needs to be explored further for its biological roles in plants than the relevant information available thus far.

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.

“…There is a need to devise strategies for new genotypes of plants with high metal accumulation and toxicity tolerance (Iqbal et al, 2015). Exogenous application of plant growth regulators (PGRs) can increase growth rate and yield of crops under both control and stress conditions (Perveen et al, 2016). However, these PGRs are sometimes very costly and most of the time not available for the farmers in different regions of the country and globally.…”

Abstract.To assess the effect of foliar applications of alfalfa (Medicago sativa L.) leaf extract on three wheat (Triticum aestivum L.) varieties (Punjab-2011, Millat-2011 and Galaxy-2013 under cadmium (Cd) stress, two-week-old wheat plants were subjected to three levels of Cd (i.e. 0, 0.5 and 1.0 mM) stress and then foliarly applied with alfalfa leaf extract (0 and 2 % w/v). Data for 16-week-old wheat plants were collected for growth and physiochemical parameters, while yield were obtained at maturity. Cadmium stress significantly decreased growth, chlorophyll (chl.) a, flavonoids, total free amino acids, total soluble sugars and relative water contents (RWC %), while increased chl. b, relative membrane permeability (RMP %), malondialdehyde (MDA), total phenolics and free proline contents. Foliar treatment with alfalfa leaf extract (2%) significantly increased growth, yield, leaf ascorbic acid, free proline and total soluble sugars, while decreased RMP (%) (in Punjab-2011 and Galaxy-2013), flavonoids and H 2 O 2 contents in all wheat varieties under cadmium stress. Wheat varieties showed significant difference as var. Punjab-2011 excelled in all measured attributes except RMP (%), MDA and activity of POD, however, negative effect of cadmium stress was more prominent in var. Punjab-2011 than Millat-2011 and Galaxy-2013
