Monitoring of xylem formation in Norway spruce in the Czech republic 2009
Original language description
The progress of xylem formation in Norway spruce (Picea abies (L.) Karst.) was measured during one growing season in Rajec-Němčice in the Czech Republic. Tissue samples were taken at weekly intervals by means of Trephor tool, from April to October 2009.The formation of new tracheid was studied with light microscope. The cambium began its division activity between 16th and 30th April and the development of new cells finished between 27th August and 17th September. The average length of time of the cambium activity was 4.8 months. The total time of wood formation was 153 days, i.e. 5.1 months. The cambium achieved maximum width (9.9 cell layers) in June, dormant cambium contained 4.6. Fitting xylem increments to the Gompertz function showed that the period of most intensive cell formation was at the turn of June and July. The total time necessary for the development of most cells differs when the WCDcalc script (153 days) is used and when the Gompertz function (174 days) is used.
