Mineral Nutrition In vitro ̵1 a Mechanistic Approach

Abstract

The supply of minerals in the medium is an essential part of plant tissue culture systems. Currently used media are largely based on empirical modifications to a few basic formulations. Optimum requirements vary widely between plant genotypes and culture systems and, as yet, it is not possible to predict the mineral requirements of untried species. A more mechanistic approach is presented which may improve this situation. Published literature and some current research aimed at a better understanding of the process of mineral nutrition in vitro are reviewed.
