Abstract

Abstract Carnation (Dianthus caryophyllus ‘Servantes’) is a popular and economically cut flower widely used in the florist industry. However, post-harvest senescence occurs in a few days and limits the cut carnation flowers’ commercialization. Therefore, this research was performed to investigate the impact of essential oils such as tea tree oil (TTO), pumpkin seed oil (PSO), Moringa seed essential oils (MEO), and Eucalyptus oils (EEO), as eco-friendly preservative solutions to enhance the quality and longevity of carnation flowers. Carnation cut flowers were submitted to different concentrations (250 and 500 mg L-1) of each essential oil used in the vase solution and the experiments were carried out as a completely randomized design in three replicates. The findings revealed that the longest vase life and the maximum total water solution uptake in cut carnation were achieved when treated with either TTO or PSO oil at 500 mg L-1 in solution preservative as compared to the control (distilled water). While the highest relative fresh weight was observed at 500 mg L-1 PSO, the highest chlorophyll a, b, total carotenoids, total sugar, total phenolic content in leaves, anthocyanin content, and enzyme activity in petals at 500 mg L-1 TTO and PSO. Additionally, all treatments of selected oils have positively declined the bacteria activity compared to control. Also, the lowest bacteria growth on third day with 500 mg L-1 TTO and PSO. However, observing a prim state of xylem vessels with TTO 500 mg L-1and PSO 500 mg L-1, comparable with distilled water, the application of essential oil in this study as a natural preservative in preservative solution as an alternative to chemicals could be of environmental value and great economic.

研究石竹切花的采后特性、化学成分及不同精油的抑菌活性

摘要康乃馨（Dianthus caryophyllus‘Servantes’）是一种流行且经济的切花，在花店中广泛使用。然而，收获后的衰老发生在几天内，限制了康乃馨切花的商业化。因此，本研究旨在研究茶树油（TTO）、南瓜籽油（PSO）、辣木籽精油（MEO）和桉树油（EEO）等精油作为环保防腐剂溶液对提高康乃馨花质量和寿命的影响。将康乃馨切花置于花瓶溶液中使用的每种精油的不同浓度（250和500 mg L-1）下，并在三个重复中以完全随机设计的方式进行实验。研究结果表明，与对照（蒸馏水）相比，用500 mg L-1的TTO或PSO油在溶液防腐剂中处理康乃馨，其花瓶寿命最长，总水溶液吸收量最大。而在500 mg L-1的PSO下观察到最高的相对鲜重，在500 mg L~（-1）的TTO和PSO下，叶片中的叶绿素a、b、总类胡萝卜素、总糖、总酚含量、花青素含量和酶活性最高。此外，与对照组相比，所选油的所有处理都积极降低了细菌活性。此外，添加500mg L-1 TTO和PSO的第三天细菌生长最低。然而，观察到TTO 500 mg L-1和PSO 500 mg L-1的木质部导管的原始状态，与蒸馏水相当，本研究中精油作为天然防腐剂在防腐剂溶液中的应用，作为化学品的替代品，可能具有环境价值和巨大的经济价值。

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.
