Summary.-The results reported describe the effects of sucrose concentrations (80, 100 and 140 gJ'), storage temperature at4°C or gibberellic acid treatment (GA 3 ) on in vitro potato (Solanum tuberosum L.) microtuber dormancy and their germination. High concentration of sucrose (140 gJ') and cold environment shorten microtuber dormancy period. On the other hand, germination is more rapid and homogenous with an increase in the 4°C storage period. GA 3 does not allow suppression of dormancy but simply stimulates germination at the end of the dormancy period. At a concentration superior or equal to 10·'M, GA 3 increases the length of the plantlets.
