Abstract
Genetical improvement of forest trees is a technique which requires support from several fields of biological science. Mirov recently has sketched in the JOURNAL OF FORESTRY the contribution which plant physiology may be expected to make. In the present paper the importance of cytology--the study of cells, their contents and activities--is illustrated by a discussion of some problems and lines of research encountered in the genetical improvement of forest trees. This is prefaced by a brief account of cells and chromosomes as they behave in development and reproduction.
