Interpretive Summary:

Technical Abstract: Biological indexing is based upon the ability of certain plants, referred to as indicator plants or indicators, to produce specific symptoms when inoculated with a pathogen using mechanical means or grafting. In the case of citrus viroids, clonal indicators are grafted on to vigorous rootstocks such as rough lemon. The ‘A-861-S-1’ citron clonal indicator can detect all citrus viroids except CVd-IIb and CVd-IIc, for which the clonal indicator ‘Parson’s special # 9’ mandarin is used. Inoculation techniques and symptom expression is described in detail. Other supporting elements, such as greenhouse conditions and propagation techniques, are also presented.
