Evaluation of susceptibility of commercial citrus rootstocks to white root rot incited by Rosellinia necatrix
Spain reached the fifth position of citrus production and the first of fresh fruit exporter worldwide. Pre-harvest diseases caused by soil-borne pathogens can limit citrus crop production. Phytophthora spp. are considered the most serious soil-borne pathogens of citrus crops worldwide, but their management strategies are highly developed. Conversely, Rosellinia necatrix is another soil-borne pathogen with polyphagous behavior, including citrus trees, and without fully-effective control tools. In this sense, the aim of this study was to characterize the susceptibility of several commercial citrus rootstocks to R. necatrix disease. Potted plants from 10 different rootstocks were artificial inoculated with an isolate of R. necatrix. Plant physiological measurements of above-ground symptoms, chlorophyll content, biomass and leaf area were obtained. Flying Dragon and Forner-Alcaide 517 citrus rootstocks displayed the lowest disease incidence of SAUDPC, whereas Citrus macrophylla the highest symptoms rate. The highest chlorophyll content was found in Forner-Alcaide 517, and the lowest in Citrus macrophylla and Bitters C-22. Additionally, this last rootstock reached the highest reduction of biomass and the lowest leaf area rate. In conclusion, Forner-Alcaide 517 could be an interesting choice for those orchards with R. necatrix problems; contrarily, Citrus macrophylla and Bitters C-22 were the most sensitive candidates to this pathogen.
期刊介绍：
The Journal of Plant Pathology (JPP or JPPY) is the main publication of the Italian Society of Plant Pathology (SiPAV), and publishes original contributions in the form of full-length papers, short communications, disease notes, and review articles on mycology, bacteriology, virology, phytoplasmatology, physiological plant pathology, plant-pathogeninteractions, post-harvest diseases, non-infectious diseases, and plant protection. In vivo results are required for plant protection submissions. Varietal trials for disease resistance and gene mapping are not published in the journal unless such findings are already employed in the context of strategic approaches for disease management. However, studies identifying actual genes involved in virulence are pertinent to thescope of the Journal and may be submitted. The journal highlights particularly timely or novel contributions in its Editors’ choice section, to appear at the beginning of each volume. Surveys for diseases or pathogens should be submitted as "Short communications".
