Karyotypes in the Genus Pseudotsuga
Forest Science, 1972Abstract Previous investigators have shown that P. menziesii has a haploid chromosome number of 13, and both P. macrocarpa and P. wilsoniana have haploid numbers of 12. This study shows that each

Phytochemical and pharmacological properties of the genus Pseudotsuga
FitoterapiaPseudotsuga is a crucial genus of timber trees in the Pinaceae family, comprising approximately 18 species that are predominantly found in western North America and East Asia. Over the past several decades, scholarly attention has primarily focused on the phytochemical study of Pseudotsuga menziesii, revealing a diverse range of compounds, including ...

Rhabdogloeum pseudotsugae Sydow has been suspected of being the imperfect stage of Rhabdocline pseudotsugae Sydow since their original description by Sydow in 1922. Because Rhabdogloeum has been reported so seldom in North America, and never in Europe, this possibility has been considered slight by most investigators.

CAMBIAL DIVISIONS IN PSEUDOTSUGA MENZIESH
American Journal of Botany, 1968Mitotic activity in the vascular cambium was determined from nine samples from a single internode in each of four Douglas‐fir ( Pseudotsuga menziesii [Mirb.] Franco) trees. Counts of mitotic nuclei and populations of potentially dividing cells in each sample were used to determine the average

THE EMBRYOGENY OF PSEUDOTSUGA TAXIFOLIA (LAMB.) BRITT
American Journal of Botany, 1943LAWSON (1909) described the life history of Pseudotsuga from material collected in the Santa Clara mountains of California. The present study was directed towards confirming Lawson's findings and towards arriving at an average time-table of reproduction which could be used as a basis for a physiological study of seed production by Douglas fir in the ...
