Abstract
The biology of two sweetener, tropical plants was studied in green house. Abrus precatorius L. (Papilionacaee) contains a sweetening agent in its leaves and roots : glycyrrhizin.
Its grains insert an antitumoral and toxic substance : abrin.
Germination of seeds is very difficult.
In contrary, propagation by stem cuttings succeeds easily.
CO2 enrichment of the atmosphere is favorable to foliage harvesting, but only when nitrogen in nutritive solution is supplied as nitrate. Synsepalum dulcificum SCHUM (Sapotacaee) contains in its fruit a glycoprotein : miraculin, which has the property to convert acid-flavoured foods into sweetened: it is a taste-modifying substance.
The plant cultivation can only be successful on an acid substratum.
Seed germination is rather difficult: a 25°C temperature seems appropriate.
