01/2007; Source: DOAJ  ABSTRACT Thirty-seven South American
species representing seven sections of Solanum subgen.
Leptostemonum were analyzed. Andromonoecious as well as
hermaphrodite species were considered. The length and width of
their fruits was measured, and the number of seeds per fruit was
counted. Medial cross sections of fresh, ripe fruits were
observed with a stereoscopic microscope and illustrated. Six
placentation patterns and three types of seeds were described. A
relationship among seed number, fruit size, fruit color and
sexual system was detected by means of statistical analysis.
These results suggest that andromonoecy affects fruit size and
placentation patterns, in order to contain a higher number of
seeds per fruit.  0 0 1 Bookmark   • American Journal of Botany
