Nutrient Uptake by Woody Root Systems
The fine-root system of perennial, dicot woody species can be dominated by brown roots. Although as much as 90% of the surface area of a root system can be in this category of roots, the nutrient uptake characteristics of brown roots are not well understood. If this part of the root system has active uptake, then its significance is obvious. If it does not then modelling predictions of nutrient...

15 صفحه اولA dynamic model of nutrient uptake by root hairs.
Root hairs are known to be important in the uptake of sparingly soluble nutrients by plants, but quantitative understanding of their role in this is weak. This limits, for example, the breeding of more nutrient-efficient crop genotypes. We developed a mathematical model of nutrient transport and uptake in the root hair zone of single roots growing in soil or solution culture. Accounting for roo...
متن کاملUpdate on Root Nutrient Foraging Root Nutrient Foraging
During a plant’s lifecycle, the availability of nutrients in the soil is mostly heterogeneous in space and time. Plants are able to adapt to nutrient shortage or localized nutrient availability by altering their root system architecture to efficiently explore soil zones containing the limited nutrient. It has been shown that the deficiency of different nutrients induces root architectural and m...
