Increasing atmospheric CO 2 concentration to 980 µ mol mol − 1 increased biomass production of the woody legume Acacia smallii more then 2.5-fold during the initial year of growth
We used soil CO 2 efflux and litterfall measurements to estimate total below- ground carbon allocation (root production and root respiration) by the carbon balance method,
Signi®cant increases in both soil respiration and root biomass (50 and 30%, respectively) were detected in a mid-successional lowland forest soil exposed to el- evated atmospheric [CO
perenne towards elevated CO 2 (more carbon input, no altered microbial meta- bolic behaviour and retarded decomposition of roots and root-derived material) is most interesting in
That infection threads are formed in the root hairs of the transgenic plants suggests that lectins mediate rhizobial attachment even within the thread (Figure 2).. Nevertheless,
(a) Biomass of fine roots (diameter 5 2 mm), and (b) ratios of leaf to fine root biomass of 2-year-old saplings of pedunculate oak, which were grown on nutrient solutions differing
When furrows were alternately irrigated maize plants showed high numbers of primary root initiation and more root biomass build-up in the soilS. Table 2 presents data showing that
The daily gross CO 2 assimilation is allocated to respiration, growth of organs (leaves, tap root, ®brous roots) and to sugar storage. 3 shows cumulative simulated dry matter
