Abstract:
:In this paper we describe a simple method to improve the plating efficiency in plant cell cultures.Two-stage plating is used; in the first stage the cells are inoculated at high density in 0.2% agarized culture medium for ten days to facilitate growth; under this condition, each cell produces a single micro-colony trapped in the agar network. In the second stage the colonies are plated at different densities in 1% agarized medium.These colonies are self-sufficient and able to improve the cell growth by conditioning the medium.
