CAMBIAL ACTIVITY IN ALASKAN WHITE SPRUCE

American Journal of Botany, 1971
Cambial activity in white spruce stems in Alaska was observed during a 2‐year period in 50–60‐year‐old natural stands. Mitotic index was used as a measure of the rate of periclinal division of fusiform cells in the cambial zone. Anticlinal divisions were relatively rare, averaging only one per 27S periclinal divisions in most stems.
