探讨盆栽条件下接种方式对甘薯腐烂茎线虫侵染量的影响,并对甘薯茎叶组织中腐烂茎线虫虫口分布及萌芽甘薯的生育期抗性进行了测定。结果表明,接种块植入甘薯中线虫侵染量最高,每g组织达408条,且症状最严重,茎组织中线虫分布最远到达距茎基部90 mm的茎组织。另外,与对照相比,萌芽甘薯对腐烂茎线虫的生育期抗性显著。本文首次报道甘薯腐烂茎线虫侵染甘薯茎叶组织的最远位置和萌芽甘薯的生育期抗性,不同接种方式对甘薯腐烂茎线虫侵染量影响的研究结果,为阐述通过病害传播途径防治该病害提供了理论依据。
The effects of inoculation method on the infection rate of D.sinensis were studied under potted conditions. The distribution of D.subtilis and the resistance of budding sweet potato during the growth period were also determined. The results showed that inoculation block inoculated sweet potato nematode infection, the highest per g of tissue up to 408, and the most serious symptoms, the distribution of nematodes in stem tissue farthest reach the stem from the base of the stem 90 mm. In addition, compared with the control, the sprouting sweet potato had significant resistance to the growth of D.sinensis. This paper reports for the first time the report of Drosophila melanogaster infestation of sweet potato farthest position and shoot sweet potato growth period resistance, different inoculation methods on sweet potato spoilage Ditylenchus nematodes infection of the results, in order to elaborate the disease transmission route Disease provides a theoretical basis.
