摘要
由 Stagonosporopsis cucurbitacearum 引起的茎枯病(GSB)是影响黄瓜(Cucumis sativus L. )生产的最具破坏性的真菌病害。在泰国,黄瓜是最畅销的蔬菜之一,黄瓜或葫芦科植物的种植经常面临流行病和虫害的影响。此外,全球气候或气候变化也会影响作物生产,增加病虫害爆发的频率和严重程度。硅(Si)能增强植物对害虫、真菌、细菌和病毒性疾病的抵抗力,虽然硅不是唯一对植物有益的元素,但它在改善植物健康和增强对病虫害的抵抗力方面也发挥着重要作用。因此,本研究旨在通过 4 次重复的随机完全区组设计,研究在两个水平(即 50 ppm 和 100 ppm)施用硅对温室条件下黄瓜产量、产量成分、香气、硅浓度和病害反应的影响。结果表明,与对照相比,50 ppm Si 的果重、上市产量、果长、果宽和髓长最高。此外,Si 含量越高,果皮(外果皮)的香气越浓,果皮(外果皮)、叶片和嫩枝中的 Si 浓度百分比也越高。此外,该研究还调查了黄瓜茎枯病(GSB)的反应。根据形态-分子分析的证据,确认了葫芦拟囊孢菌的分类鉴定,并进行了致病性试验,以确认其潜在的致病性。结果表明,不同处理的 Si 会影响病害的发展。50 ppm Si 对黄瓜果实的病害反应最小。这项研究可作为调整植物施硅肥投入量的指南,以提高抗病性和果实品质。
Effect of Silicon on the Fruit Quality and Disease Response to Gummy Stem Blight in Cucumber
Gumm y stem blight (GSB) caused by Stagonosporopsis cucurbitacearum is the most destructive fungal disease affecting cucumber (Cucumis sativus L.) production. In Thailand, cucumber is one of the most popularly marketed vegetables and the cultivation of cucumbers or Cucurbitaceae often face impact epidemics and insect infestation. Furthermore, global climatic or climate change affects crop production too, which increases the frequency and severity of disease and pest outbreaks. Silicon (Si) enhances plant resistance against insect pests and fungal, bacterial, and viral diseases although Si is not the only beneficial element for plants but also it does play an important role in improving plant health and increasing resistance against pests and diseases. Therefore, the aim of the study was to investigate the effect of Si-application at two levels i.e., 50 ppm, and 100 ppm on yield, yield components, aroma, Si-concentration and disease response of cucumber under greenhouse condition in a randomized complete block design with 4 replications. Results, when compared with control, depicted that the highest fruit weight, marketable yield, fruit length, fruit width, and pith length were found under 50 ppm Si. Moreover, higher Si-levels resulted in increased aroma in rind (exocarp) and increased percentage of Si-concentrations in rind (exocarp), leaves, and shoot. Further in this research, the response of Gummy stem blight disease (GSB) in cucumber was also investigated the response of. The taxonomic identification of Stagonosporopsis cucurbitacearum was confirmed based on the evidence from morpho-molecular analyses and the pathogenicity test was performed to confirm its potential pathogenicity. The results showed that the varying treatments of Si affects the disease development. The 50 ppm Si caused the lowest disease response on cucumber fruits. This study can be used as a guideline for modifying Si-fertilizer application inputs to plants to increase disease resistance and fruit quality.
期刊介绍:
The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
