%X Diurnal patterns of stem elongation varied with ambient temperature. Stem elongation was more rapid during the day at lower (20-24&#176;C) day/night temperatures. However, the proportion of night growth increased with increasing temperatures from 30% of the daily total at 20° to 100% at 30&#176;. A decline in both the number and duration of growth flushes appeared to explain the low level of shoot elongation at higher (28&#176; and 30&#176;) day/night temperatures. Under the given experimental conditions, diurnal rhythms in stem elongation reflected ambient temperature rather than seedling water potential.
