1. Ray tracheids, marginal, interspersed, and elongated, were observed in association with wounds in A. amabilis and A. concolor. 2. They were also observed in uninjured material of A. homolepis and A. Veitchii. 3. Their usual position was in contact with a series of degenerated cells on one hand and a group of parenchyma on the other. 4.

Identifying the main drivers for the production and maturation of Scots pine tracheids along a temperature gradient [PDF]
Even though studies monitoring the phenology and seasonal dynamics of the wood formation have accumulated for several conifer species across the Northern Hemisphere, the environmental control of tracheid production and differentiation is still ...

How to quantify conduits in wood?
Vessels and tracheids represent the most important xylem cells with respect to long distance water transport in plants. Wood anatomical studies frequently provide several quantitative details of these cells, such as vessel diameter, vessel density ...
