WebDec 21, 2001 · The root lifespan that maximizes efficiency can be visualized by plotting E lifetime over time, and represents the theoretically optimal root life span ( Yanai et al., … WebJul 11, 2008 · The shorter root life span would facilitate root turnover and generation of young root, which in turn would favour water and nutrient use efficiency, thus allowing L. chinensis to better cope with their stressed habitats. Physiologically, rhizomes are strong sinks to compete for photoassimilates with roots. As a result, it is conceivable that ...
Regional scale patterns of fine root lifespan and turnover …
WebDifferences in the life-span between root diameter and root order affect estimates of root turnover. Therefore, based on this study, both diameter and order should be considered when estimating fine root life-span and turnover.

Variability in root production, phenology, and turnover rate …
WebJul 1, 2000 · Elevated CO 2 increases the absolute fine-root turnover rates; however, the standing crop root biomass is also greater, and the effect of elevated CO 2 on relative turnover rates (turnover[ratio ]biomass) ranges from an increase to a decrease. At the ecosystem level these changes could lead to increased C storage in roots. Webfor roots excavated from mature apple and citrus trees (median root life spans of 30 vs 300 d). To evaluate whether root longevity maximizes the efficiency of nutri-ent capture, daily … Webanisms controlling root turnover is likely to be found in the still poorly-defined relation between root function and root age. Yanai etat (1995) introduced a cost-benefit model to explore whether root life span maximizes the efficiency of nutrient capture, with efficiency defined as the ratio of nutrient buzzfeed what is privilege
