Seed priming is a pre-sown treatment and it is often used to improve the performance of plants in any environment, especially germination. In the current study, various concentrations of nitric oxide (NO) were used to evaluate its role for the induction of physiological variations within seven different wheat (Triticum aestivum L.) genotypes. Two experiments were conducted during 2013 and 2014 and the data were statistically analysed for significance. All these genotypes after treatment with sodium nitroprusside (SNP) as NO donor at 10−4 and 10−5 M concentrations were sown following randomized complete block design with triplicates in the fields of District Muzaffarabad, Pakistan. The concentration of NO at 10−4 M showed promising results and most of the studied characters were found improved compared to control. Wheat varieties primed with 10−4 M SNP showed highest germination speed and germination percentage. NARC-2011 and Uqab-2002 showed much improvement in physiological attributes at both concentrations of NO priming. However, Uqab-2002 and Punjab-2011 showed a significant increase in chlorophyll contents and leaf moisture content with 10−4 and 10−5 M SNP priming compared to control. Highest relative water content was observed within unprimed Lasani, whereas the relative injury was found to be decreased at 10−4 M SNP primed Faisalabad-2008. Wheat varieties Punjab-2011 and Faisalabad-2008 showed the highest increase in grain yield and biological yield by 10−4 M SNP. Hence, it is concluded that sowing of crops after priming at 10−4 M NO concentration can improve the germination, biochemistry and physiology that ultimately lead to an increase in crop yield.

评价一氧化氮引发以改善面包小麦的生理机能

种子引发是一种播前处理，通常用于提高植物在任何环境中的性能，尤其是发芽。在目前的研究中，不同浓度的一氧化氮 (NO) 被用来评估其在七种不同小麦中诱导生理变化的作用。小麦L.) 基因型。在 2013 年和 2014 年期间进行了两次实验，并对数据的显着性进行了统计分析。在 10 用硝普钠 (SNP) 作为 NO 供体处理后的所有这些基因型-4和 10-5M 浓度在巴基斯坦穆扎法拉巴德区的田间按照随机完整区组设计进行播种，一式三份。NO浓度为10-4M 显示出有希望的结果，并且发现与对照相比，大多数研究的特征都得到了改善。用 10 引发的小麦品种-4M SNP表现出最高的发芽速度和发芽率。NARC-2011 和 Uqab-2002 在两种 NO 启动浓度下都显示出生理特性的显着改善。然而，Uqab-2002 和 Punjab-2011 显示叶绿素含量和叶片水分含量显着增加，10-4和 10-5与对照相比，M SNP 引发。在未涂底漆的 Lasani 中观察到最高的相对含水量，而相对损伤在 10-4M SNP 为费萨拉巴德 2008 年启动。小麦品种 Punjab-2011 和 Faisalabad-2008 的谷物产量和生物产量增幅最高，增加了 10-4M单核苷酸多态性。因此，得出的结论是，在 10-4M NO 浓度可以改善最终导致作物产量增加的发芽、生化和生理。
