Chilling stress is one of the stresses that affect the most of the important cereal crops.&nbsp; In order to investigate the role of nitric oxide in mitigating chilling induced physiological variations of wheat (<em>Triticum aestivum</em> L.) at early seedling development, two experiments were conducted during the year 2012 and 2013 and the data was statistically analyzed in MSTAT-C computer package. Seven wheat genotypes after seed priming in 0, 10-4 and 10-5 M sodium nitroprusside (as nitric oxide donor) were grown according to completely randomized design with three replicates in optimum growth conditions. Nitric Oxide donor priming at 10-4 M concentration was found to be more effective in reducing cold stress. The study of physiological attributes of the seedlings revealed that NARC-2011, Chakwal-50, Punjab-2011 and Faisalabad-2008 are comparatively more tolerant to chilling stress in association with NO priming.</p> Chilling, Priming, Nitric Oxide, Wheat Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2017-JAPS-23
