The summer solstice is not just a calendar entry. It is a signal to all the trees in temperate zones in the north to begin preparation to survive the winter cold. Yes, today, the growing season ends for most trees. Have a look at the trees you walk by. Most of them have probably already set buds.

4/The trigger for phellem differentiation is mechanical: endodermis rupture releases constraints on underlying pericycle cells, allowing them to expand and differentiate into phellem. We prematurely relieved mechanical constraints and saw that it is sufficient to trigger phellem differentiation. 🛡️
