摘要

提高作物产量的方法多种多样。种子催芽是目前最简单、成本最低的方法之一，可确保快速和均匀的产量。我们的研究强调了催芽和浸种在提高种子萌发方面的作用。本研究的目的是调查种子浸种和 0.1 mM 赤霉素（GA3）激素催芽对发芽性能和葫芦巴（Trigonella foenum-graecum L.）胚根生化变化的影响。结果表明，水刺和 GA3 浸泡能显著改善发芽性能和胚根生长。同时，处理还能刺激超氧化物歧化酶、抗坏血酸过氧化物酶、过氧化氢酶和愈创木酚过氧化物酶的抗氧化活性，降低脂质过氧化反应，刺激非酶抗氧化总能力和还原型谷胱甘肽含量的增加。过氧化氢的积累和活性氧（ROS）的原位细胞化学分析证实了浸泡在刺激 ROS 方面的作用。有趣的是，赤霉素浸泡比激素浸泡更有效，这可能是由于 GA3 在脱水过程中部分降解。

Effects of hormopriming and pretreatment with gibberellic acid on fenugreek (Trigonella foenum graecum L.) seed germination

Various approaches are used to improve crop production. Seed priming is one of the simplest and least expensive methods currently used to ensure rapid and uniform yields. Our study highlights the role of priming and imbibition in improving seed germination. The objective of this study was to investigate the effect of seed imbibition and hormopriming with 0.1 mM gibberellic acid (GA3) on germination performance and biochemical changes in fenugreek (Trigonella foenum-graecum L.) radicles. The results showed that hydropriming and imbibition with GA3 significantly improved germination performance and radicle growth. Concurrently, treatments induced stimulation of the antioxidant activities of superoxide dismutase, ascorbic peroxidase, catalase and guaiacol peroxidase, and decreased lipid peroxidation, stimulated an increase in total non-enzymatic antioxidant capacity and reduced glutathione content. Accumulation of hydrogen peroxide and cytochemical analysis of reactive oxygen species (ROS) in situ confirmed the role of imbibition in stimulating ROS. Interestingly the effects of imbibition with gibberellic acid were more effective then hormopriming, probably due to the partial degradation of GA3 during dehydration process.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
