Abstract:
Leaf and stem inoculations of lemon seedlings with Phoma tracheiphila resulted in severe infection and did not reflect satisfactorily the reaction of lemon cultivars to natural mal secco infection in the field. A tolerance rating by stem inoculation was closer to known field performance of lemon cultivars. The tolerance was affected by the rootstock, with Citrus volkameriana conferring a higher tolerance than Sour orange (C. aurantium) or Rough lemon (C. jambhiri). The field inoculation test gave ratings of tolerance closest to natural infection data; Monachello was the only tolerant cultivar, and Santa Teresa showed slight tolerance. © 1978, Springer Science + Business Media B.V..
