Abstract

Leaves of tobacco plants inoculated with tobacco mosaic virus were divided into three groups : (a) inoculated leaves; (b) younger non-inoculated leaves present at the time of inoculation; (c) leaves formed since inoculation. The respiration rate of each group was compared with that of similar leaves from healthy plants. The respiration rate of inoculated leaves was increased by a constant amount for 3 weeks after inoculation, when it decreased. The respiration rate of group (6) leaves was not affected at any time, and that of group (c) leaves was decreased by 10 % when they showed symptoms. The increased respiration in the inoculated leaves occurred too soon to reflect virus formation, and it is suggested that it reflects an initial change in infected cells preparatory to virus synthesis. The subsequent decrease in respiration may be due to the accumulation of virus which does not contribute to the total leaf respiration.
