In poinsettia production, this indicator is used to classify varieties by growth habit, for example, as compact or medium-vigor varieties. This is critical for determining planting schemes and planning in advance the application of growth regulators needed to manage plant habit.
Under cool-growing conditions, vigor becomes a key factor, as varieties with high developmental energy are preferred to compensate for the slowing of processes caused by lower temperatures. This ensures the formation of a marketable plant exactly by the scheduled sales dates.
