Leaf area index development and radiation use efficiency of a poplar short rotation coppice culture
Tripathi, Abishek ; Fischer, Milan ; Trnka, Miroslav ; Orság, Matěj ; Vanbeveren, S. ; Marek, Michal V.
Leaf area index (LAI) is the most appropriate parameter for analyzing canopy structure and crop productivity. LAI and radiation use efficiency (RUE) were estimated to evaluate the productivity of a short rotation coppice culture of a poplar clone. RUE was calculated as the ratio between total aboveground woody biomass and available photosynthetic active radiation (PAR) accumulated during one growing season. Prior to coppicing, LAI reached a maximum value of 7.3 (in 2009), whereas the maximum LAI after coppicing was 6.8 (in 2012). The maximum RUE reached prior to coppicing was 0.25 g mol−1 (in 2009), while after coppicing it was 0.20 g mol−1 (in 2012), which did not represent a significant difference (p > 0.05).
