Temporal variation and efficiency of leaf area index in young mountain Norway spruce stand

Popis výsledku v původním jazyce

Temporal variation of leaf area index (LAI) in two young Norway spruce stands with different densities was monitored during eight consecutive growing seasons (1998-2005). We were focusing on: 1) LAI dynamics and aboveground mass production of both sprucestands and their comparison, 2) leaf area duration (LADU), crop production index (CPI) and leaf area efficiency (LAE) evaluation, and 3) thinning impact on above mentioned parameters. Also, we tried to deduce the most effective LAI value for the Norwayspruce forest investigated. The LAI values of both spruce stands showed the typical seasonal course. To describe the LAI dynamics of the stand, we recommend taking LAI measurements within short time intervals at the time of budding and needle expansion growth (i.e. in early spring) and close to the LAI peak, when the twig growth has been completed. The reason is that after reaching the seasonal maximum, no significant differences between subsequently obtained values were found within the
