period. To compare the timing of root production and the aboveground organs’ production, we used the CASSIA model, which estimates the aboveground tree carbon dynamics . In this study, root growth started ...
-level biomass was partitioned after 2 years of growth at UCP as foliage, (42.7%), branches (11.2%), stem (25.3%), taproots (12.5%), coarse roots (8.3%), and fine roots (2.7%), and there was very little ...
, and soil texture (Sands 2004). Time series data— inputs required to define the initial conditions of a stand are dry biomass (Mg ha−1) of foliage (WF), of stem including branches and bark (WS), and of roots ...
(International Energy Agency 2012). Meeting these demands will require substantial development of bioenergy crops , including woody biomass . Importantly, to prevent bioenergy from affecting food prices, China ...
aboveground biomass was investigated. The general observation from studies on root growth under elevated CO2 is that root growth is stimulated, resulting in an increase in the root to shoot ratio (Norby 1994 ...
