The objective of this study was to assess the effectiveness of a computerized system for seedling image analysis to determine the processing tomato seed lot's vigor. 'BRS Sena', a processing tomato hybrid from Embrapa Hortaliças, was used in this study. Seeds were placed previously in an aging chamber for 0, 24, 48, 72 or 96 h at 41°C and 60% RH, generating five seed lots. After this period, seeds were submitted to the first count, germination, seedling emergence, saturated salt accelerated aging, and the Seed Vigor Imaging System - SVIS® test. The computerized analysis system provided data on the vigor index, uniformity of development, and seedling growth, after the fourth day of the germination test. The result obtained by SVIS® computer analysis was similar to the results of other vigor tests used in the study, detecting significant differences among vigor index, length, and uniformity of seedlings. This result demonstrates that the computerized analysis system of images may be a viable alternative for obtaining reliable information on the physiological potential of tomato seeds.  aTomate1 aNASCIMENTO, W.
