Conteúdo: | Indexing for psorosis is usually performed on Pineapple sweet orange. Partial purification of citrus psorosis virus (CPsV) was achieved from leaves of Pineapple sweet orange and Eureka lemon but infectivity on Chenopodium quinoa was usually low. We tested 14 citrus species and cultivars as psorosis indicators and as sources for CPs v purification. Typical psorosis symptoms on seedlings inoculated with isolate 90-1-1 were recorded and infectivity assayed on c. Quinoa, with the folowing results:1)At 30 days post infection temple mandarin, Cleopatra mandarin and Eureka lemon were as good as Pineaple sweet orange indicators of psorosis.Trifoliate orange, Troyer citrange, king of siam mandarin, rough lemon, Malvasio mandarin,Ducan grapefruit, sour orange, Rangpur llime,Madame Vinous sweet orange and Ellendale mandarin were poor indicatrs;2)Leaf material from Temple mandarin and rough lemon was in general more infectious than that from Eureka lemon and Pineapple sweet orange . King of siam mandarim, Ducan grapefruit, Cleopatra mandarin,sour orange and rangpur lime constently produced less infectious material;3)Survival of Temple mandarin was shorter than rough lemon and Eurekalemon was longer than rough lemon. Two conclusions were reached:a)Temple mandarin, Cleopatra mandarin and Eureka lemon could be used as Pineapple sweet orange for psorosis indexing; b)rough lemon could advantageously replace eureka lemon and Pineaple sweet orange as source of material for CPs V propagation.
