N2  - Onion (Allium cepa L.) cultivars Creamgold and Gladalan Brown were grown at three day lengths (13, 14 and 15 h) and three day temperatures (22, 26 and 30¦C) in the Canberra phytotron. In each case bulbing was slower whcn the night temperature was 15' below day temperature than at 5¦ below day temperature. The cultivar Gladalan Brown, growing at 13 h day length and 26¦C day temperature, bulbed faster when the first half of the 11 h night was at 21¦ and the second half at 11¦ than in a 11¦ then 21¦ night. The number of days from sowing to the start of bulbing decreased with increasing night temperature. The rate of bulbing after initiation increased with increasing night temperature.
