Abstract
THE term ‘streak’ has been applied to a diseased condition of the potato in which the leaf and stem tissues become to a greater or lesser extent involved in a necrotic process. The condition was first described as a separate disease by Atanasoff under the name of ‘stipple streak’, and has since received considerable attention from the clinical point of view from Quanjer and others. In this Institute I have shown how ‘streak’ may be but an alternative symptom of another disease, namely, crinkle A; and my colleague, Dr. Kenneth Smith, that it may assume a somewhat similar relation to ringspot disease of tobacco. In the former, the change from crinkle to streak is induced by varietal susceptibility; in the latter, by passage of an original potato mosaic virus through tobacco before being used as an inoculum to reinfect the healthy potato. Streak is clearly a clinical picture which may be reproduced by different agents.
