Variety traits
Saintpaulia ionantha H. Wendl.
The vigor of Saintpaulia determines the intensity of rosette formation and the rate of vegetative mass accumulation. This trait is genetically determined and influences the time required for the plant to reach the stage of readiness for flowering.
In the reference 3 varieties crop African violet, where this is mentioned in the description.
In Saintpaulia ionantha, vigor characterizes the rate of vegetative development, expressed as the speed of forming a marketable leaf rosette. This indicator directly determines the time required for a plant to progress from a cutting or plantlet stage to a state suitable for full flowering.
In breeding and amateur practice, vigor is assessed visually by observing the dynamics of plant development, including the timing of plantlet emergence during propagation. In in vitro micropropagation, vigor is recorded as a qualitative indicator of explant viability and the rate of shoot development on nutrient media.
The expression of this trait is closely related to the physiological state of the Saintpaulia. Specifically, juvenile tissues used for vegetative propagation often possess higher vigor compared to older leaves, which accelerates the production of offspring.
