z Seventeen-day-old seedlings were grown in a greenhouse at 33 to 35ºC day and 13 to 15ºC night (control), or exposed to 31ºC for 5 weeks in a growth chamber and evaluated after 4 weeks for percentage of rosetted plants.  Values are means of four replications with eight plants as the experimental unit arranged in a randomized block design. 

y Vegetative and flowering characteristics were for non-rosetted control plants.   Values are means of five replications of single-plant experimental units arranged in a completely randomized design.

x Plant height = distance from the pot rim to the tip of the highest bud measured after three flowers had opened.

w Lateral stems originating on the central flowering stem (bolted stem) but below the first flower bud.

v Mean separation within columns by Duncan’s multiple range test, P< 0.05.
