NURSERY UNDERSTANDING OF TISSUE CULTURE
Bruce A. Briggs
The type of tissue culture which we are considering may be defined as the development of new plants in an artificial medium under aseptic conditions from very small pieces of plants. Propagation may be accomplished from embryos, seeds, tissues, stems, shoot tips, root tips, callus, single cells or pollen grains (1). For successful propagation, new roots and/or shoots or small embryos must develop in order to produce the new plants. The kind of growth pattern which develops depends upon the genetic potential of the plant cultured and upon the chemical and physical environment to which it is subjected.
We nurserymen are accustomed to using other methods of propagation but should keep our minds open to the many new future possibilities of this technique. It can accomplish a much more rapid mass production of limited propagating stock, it can recover disease-free plants, and it can show us new ideas and methods which we can apply to our current ways of propagating plants.
