X-ray microtomographic observation of tracheids embolism on cores. Images a, b, and c correspond to the 3 different characteristic zones (zone S, zone DH, and zone WH), respectively, observed in the fir trunks. Black areas indicate air-filled tracheids, and light-gray areas indicate water-filled tracheids. The boundaries between the 2 growth rings are indicated by red arrows. EW, earlywood; LW, latewood.
