Differentiation of terminal latewood tracheids in silver fir during Dormant periodGričar, Jožica ; Čufar, Katarina ; Schmitt, UweTo examine the state of differentiation in terminal latewood tracheids during dormant period, samples of wood and cambium were taken from 10 apparently healthy mature silver fir (Abies alba) trees in ... the middle of October, November and March. According to light microscopy and transmission electron microscopy, cambial activity was completed in all investigated trees in mid-October. Process of differentiation was still ongoing in the youngest tracheids close to the cambium in trees with broader annual xylem growth rings. Secondary wall of those trees was not completely formed and its inner part was unlignified. Cell wall formation and lignification of terminal tracheids were completed in all trees in November. All layers of secondary cell wall were formed, including S3 layer and warty layer, and no protoplasm in the tracheid lumina was observed in November. The cambium is more productive and its cell-divisional activity and also differentiation end laterin trees with broader annual xylem growth rings. However, differentiation in all investigated trees was completed before winter, and therefore no alterations were observed in cell structure of terminal latewood tracheids in November and March samples.Vrsta gradiva - prispevek na konferenciLeto - 2003Jezik - angleškiCOBISS.SI-ID - 1078665
