Abstract

Morphogenetic events in Prosopis tamarugo and P. chilensis calli and cell suspensions were studied in in vitro conditions. Under several growth conditions tested a generalized browning effect in tissues were observed. This effect was partially reduced by the use of cysteine in media. In P. tamarugo, shoot-like structures developed from calli after several subcultures. In P. chilensis, cell suspensions were able to form cell clusters and later on somatic embryoids. At present morphogenetic responses observed in both species occurred in a low frequency.
