Vigor of Solanum torvum Sw.

Solanum torvum Sw.

The vigor of Solanum torvum determines its effectiveness as a rootstock, characterized by high root system development energy, which stimulates scion vegetative growth, increases yield, and enhances plant resistance to abiotic and biotic stresses.

In the reference 5 varieties crop Turkey berry, where this is mentioned in the description.

For Solanum torvum, vigor manifests in the root system's ability to actively support scion development, making this species a tall and vigorous rootstock for Solanaceae. A robust root system, including a deep taproot, allows grafted plants to better tolerate drought, soil salinity, and infection by soil-borne pathogens such as nematodes or the causal agents of Verticillium and Fusarium wilt.

This trait is assessed comparatively against self-rooted plants using morphometric parameters: plant height, stem diameter at the root collar, as well as root length and biomass. High vigor is considered confirmed when there is a statistically significant superiority of these parameters and yield indicators in grafted plants over control samples.
