“…Despite evidence suggesting that commercial forest ecosystems are prime environments for the establishment of invasive alien plants (IAPs) and the need to protect these valuable and vulnerable resources (Campbell and van Staden, 1990, Little et al, 1997, Chornesky et al, 2005, very little attention has been paid to the detection and mapping of weeds in these complex ecosystems. In this context, one significant alien plant invader commonly occurring within commercial forests as well as provoking serious economic and ecologic concerns is Solanum mauritianum (Campbell andvan Staden, 1990, Little et al, 1997).…”

Callus cultures of Solarium mauritianum Stop. were initiated from green berry explants on a hormone-free Murashige and Skoog (1962) medium excluding glycine, and containing 0.1 g L-' myo-inositol and 3% sucrose. Such cultures contained 10.08 f 0.59 pg g-' DW of solasodine, which is equivalent to that in the leaves of mature S. mauritianum plants, but far less than that extracted from the green berries (185 pg g-' DW). In vitro solasodine productivity could be increased by reducing the strength of the medium by half, substituting 3% glucose for 3% sucrose as carbon source, or by the addition of certain combinations of BA and NAA. Phosphate limitation and alterations in the carbon:nitrogen ratio were not able to increase solasodine productivity. Suspension cultures of S. mauritianum were initiated and maintained in a Murashige and Skoog (1962) medium with the RT vitamins of Khanna and Staba (1968), 0.1 g L-' myo-inositol, 3% sucrose and 1 mg L-' 2,4-D. No solasodine was detectable in these cultures, or slight modifications thereof.Abbreviations: BA -benzyladenine; NAA -naphthaleneacetic acid; 2,4-D -2,4-dichlorophenoxyacetic acid; MS -Murashige and Skoog's (1962) medium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
