Petunia Vigor

Petunia Juss.

Petunia vigor determines cultivation strategy, container volume selection, and plant shaping schedules, correlating with shoot growth intensity and bush diameter.

In the reference 82 varieties crop Petunia, where this is mentioned in the description.

To assess the vigor of petunia seeds, the SVI index is used, calculated as the product of shoot length and germination percentage, as well as methods for determining seedling mass after 10 days. At the vegetative stage, the trait is evaluated expertly by the degree of shoot growth or instrumentally using the NDVI index.

High vigor is characteristic of series such as Tidal Wave and Surfinia, which require large substrate volumes of 20–30 liters per plant. Compact series, such as Littletunia, possess low to medium vigor and develop successfully in 4–8 liters of soil.

Petunia vigor directly affects agronomic practices: varieties with high growth energy require early spacing of seedlings to prevent stretching, an intensive fertilization program to support branching, and larger feeding areas, while ensuring faster recovery after trimming.
