Localized low temperatures of the stem induced narrow diameters and obvious thickening of secondary cell walls of tracheids, which were identified as latewood tracheids. In addition, artificial cooling of stems induced cessation of cambial activity.
Begum et al. consider that cambium and its derivatives can respond directly to changes in temperature and a decrease in the temperature of the stem is a critical factor in the control of cambial activity and xylem differentiation in trees.
How do tree growth rings, species and climate interact? A study into xylogenesis in Annals of Botany takes a closer look.
When the orientation of the stems of conifers departs from the vertical, conifers form compression wood that results in restoration of verticality. Intercellular spaces are formed between tracheids in compression wood...
