中文摘要：黄瓜绿斑驳花叶病毒（CGMMV）经常感染嫁接西瓜，在国内广泛分布。为了明确这种病毒病流行的贡献因素，急需调查病毒的传播模式及效率。在本研究中，作者研究发现，在葫芦种子生产基地CGMMV的发生率达到100%，但污染率和传播率分别为100%和0.92%。播种36天后，葫芦科植物叶片上表现出明显的斑点症状。一系列研究结果表明，被污染的种子、土壤以及修剪和灌溉可不同程度传播CGMMV，且都有助于CGMMV的流行。
外文摘要：Cucumber green mottle mosaic virus (CGMMV; genus Tobamovirus) infects frequently the grafted watermelon and is widely distributed in China. Investigating the transmission modes and their efficiency is urgently needed to understand the factors contributing to the epidemiology of this viral disease. In the present study, we found that the occurrence of CGMMV in a bottle gourd seed production base reached 100%, while the contamination rate and transmission rate were 100 and 0.92%, respectively. The bottle gourd plants showed obvious mottle symptom on leaves starting 36days after seed sowing. The long latent period of CGMMV in seedlings implies a potential risk to use contaminated seeds in the production of grafted watermelon. This virus could overwinter in soil with debris of infected plants, and the infection rate of CGMMV from contaminated soils was 10.30%. CGMMV could be transmitted from infected watermelon plants to healthy ones by pruning at least to the ninth plant during the whole growing season. The transmission distance was 1.87m by drip irrigation and 2.31m by flow irrigation. This study suggested that contaminated seeds, contaminated soil, pruning and irrigation could transmit CGMMV at different efficiency, and all contribute to the epidemiology of CGMMV.
