Description

Solanum boliviense distribution Map note

Solanum boliviense (boliviense should be self-explanatory) is primarily a Bolivian species, but is found from southern Peru to northern Argentina.  A plant of poor soils, growing up to about the 13,750 foot elevation, where frosts occur fairly frequently.  Plants variable in form, from low growing rosettes to erect plants reaching about 15 inches in height.  Stolons two feet long or more.  Tubers small and round, reaching about an inch in diameter, and sometimes moniliform (forming chains).  Flowers blue to purple.

This species can survive frosts down to 22 degrees F (-5.5 C) (Li 1977, as S. sanctae-rosae).  Vega (1995) found that this species is more frost tolerant than domesticated potato.

Glykoalkaloid content

Johns (1986b) found glycoalkaloid levels ranging from 1.2 to 26 mg /100 g for S. boliviense (including S. sanctae-rosae).  The primary glycoalkaloids was tomatine, but demmisine and commersonine were also present in some accessions.

Cultivation

I have found seeds of this species easy to germinate using the standard conditions for S. tuberosum, although sometimes slow.

Bamberg (2018) found that alternating temperatures increased germination in this species.

Bamberg (1995) found that at least some accessions of S. boliviense are able to produce a significant amount of viable pollen even when temperatures exceed 100 degrees F for several hours during the day.  Flowering was reduced under these conditions.

Bamberg (2017) found a 110% increase in seed set in this species with supplemental applications of liquid fertilizer at four and seven weeks after potting.

Jackson (1999) found 4-16% 2n pollen for varieties of this species.  Ochoa (1990) reported 5% 2n pollen for two accessions.
