Tomato Vigor

Solanum lycopersicum L. var. lycopersicum

A complex indicator of the vegetative state of a tomato, assessed through stem diameter, development of the leaf apparatus, and internode length. It serves as a tool for managing the vegetative-generative balance, influencing the choice of planting patterns and fertilization strategies.

In the reference 76 varieties crop Tomato, where this is mentioned in the description.

Tomato vigor is assessed by morphological characteristics: stem diameter in the upper part (standard 0.8–1.0 cm), intensity of side shoot development, leaf size, and internode length. The scientific approach relates this indicator to leaf surface area, plant dry weight, and seed germination energy.

Excessive vigor can lead to rank growth, which reduces yields, whereas low vigor indicates a nutrient deficiency or a suppressed state. Agronomists use this criterion to adjust the balance between vegetative mass accumulation and fruiting, as well as when selecting rootstocks for grafting.

Planting patterns adopted in agrotechnology depend on the vigor of a specific hybrid, as powerful indeterminate plants require larger feeding areas. Managing vigor allows the plant to maintain productivity under stress conditions and ensure stable fruit formation.
