Comparative anatomical studies of pores in the end walls of wood of members of the family Taxodiaceae using scanning electron microscopy.
Descriptions of pores are given for 11 species, viz. Athrotaxis cupressoides, A. selaginoides, Cryptomeria japonica, Cunninghamia lanceolata, Glyptostrobus pensilis, Metasequoia glyptostroboides, Sequoia sempervirens, Sequoiadendron giganteum, Taiwania cryptomerioides, Taxodium distichum and T. mucronatum. The strong gradation in pore structure across an annual ring is described. The value of SEM and the importance of observing pore structure together with its variation across the annual ring are discussed in relation to studies of fossil wood.
