^zSeventeen-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 rosette plants, n = 24.

^yVegetative and flowering characteristics were for nonrosetted control plants. Values are means of six replications of single-plant experimental units arranged in a completely randomized design.

^xPlant height 1 = distance from the pot rim to the base of the first opened flower; plant height 2 = distance from the pot rim to the tip of the highest bud measured after three flowers had opened. No growth regulators were used.^wLateral stems originating on the central flowering stem (bolted stem) but below the first flower bed.
