Abstract
Several kinds of precursors obtained by natural polymer hydrolysis of leaves, cell walls, cellulose and hemicelluloses have been tested on in vitro cultures. Interesting preliminary results were obtained with strawberry callus culture whereby all the tested hydrolysates were able to induce differentiation and organogenesis without addition of any plant growth regulators to the culture medium. This suggests the existence of one or more compounds, enzymatically released from the cell wall, which play a role on plant differentiation and organogenesis.
