| Abstract/Contents: | "The C balance of a tall fescue sward grown under different rates of N fertilization in summer, autumn, and spring was calculated using models derived from measurements of shoot growth, canopy gross photosynthesis, shoot respiration and of C partitioning to the roots. Under the diverse growing conditions associated with the seasons and the N fertilization, C utilization for above- and below-ground biomass accumulation never exceeded 39 and 14% of the canopy gross photosynthesis, respectively. Carbon losses attributed to root respiration and exudation, which were estimated by difference between canopy net photosynthesis and total growth, ranged between 3 and 30% of canopy gross photosynthesis. Seasonal differences in shoot growth could be attributed to the amount of intercepted radiation, the radiation-use efficiency and the C partitioning to the roots. The effect of N deficiency on shoot growth can be attributed to its effects on canopy photosynthesis (principally resulting from changes in intercepted photosynthetically active radiation) and C partitioning. In comparison with the effect on shoot growth, the effect of the N deficiency on the canopy gross photosynthesis per unit of light intercepted over the regrowth cycle was limited. It is concluded that most of the effect of N fertilization on shoot growth is due to changes in C partitioning which results in faster leaf area development and greater light interception." |
