Description

Solanum multiinterruptum distribution Map note

(multiinterruptum means “multiply interrupted,” presumably referring to the large number of small leaflets) Vega (1995) found that this species is about as frost tolerant as domesticated potato.

Glykoalkaloid content

Johns (1990) found levels of 50 and 68mg/100g for two accessions tested.  The primary glycoalkaloids were solanine and chaconine.  They also found a level of 42mg/100g but that accession was later reclassified.
