Douglas fir plantlets have been produced by tissue culture. Karyotypes of seedlings and plantlets were prepared from root tip squash preparations using standard histological procedures. A diploidchromosome number of 26 was common to both. The relative lengths of seedling and plantlet chromosomes were found to be similar. The frequency of occurrences of secondary constrictions was found to be high in chromosomes three and ten. Giemsa staining was successfully used to distinguish unique chromosomal banding patterns in seedlings and plantlets.
