Anatomical structure interpretation of the effect of soil environment on fine root function

open access: yesFrontiers in Plant Science, 2022
Fine root anatomy plays an important role in understanding the relationship between fine root function and soil environment. However, in different soil environments, the variation of fine root anatomical structure in different root sequences is not well ...

First-Order Convergence and Roots [PDF]

open access: yesCombinatorics, Probability and Computing, 2015
Nešetřil and Ossona de Mendez introduced the notion of first-order convergence, which unifies the notions of convergence for sparse and dense graphs. They asked whether, if (Gi)i∈ℕ is a sequence of graphs with M being their first-order limit and v is a vertex of M, then there exists a sequence (vi)i∈ℕ of vertices such that the graphs Gi rooted at vi ...

Root phosphatase activity is a competitive trait affiliated with the conservation gradient in root economic space

open access: yesForest Ecosystems, 2023
Background: The diversity of resource acquisition strategies of plant roots determines the species coexistence patterns to a certain extent. However, few root physiological traits have been investigated, such as root phosphatase activity (PA) that ...

A root is a root is a root? Water uptake rates of Citrus root orders [PDF]

open access: yesPlant, Cell & Environment, 2010
ABSTRACTKnowledge about the physiological function of root orders is scant. In this study, a system to monitor the water flux among root orders was developed using miniaturized chambers. Different root orders of 4‐year‐old Citrus volkameriana trees were analysed with respect to root morphology and water flux.

The Right-Skewed Distribution of Fine-Root Size in Three Temperate Forests in Northeastern China

open access: yesFrontiers in Plant Science, 2022
Trees can build fine-root systems with high variation in root size (e.g., fine-root diameter) and root number (e.g., branching pattern) to optimize belowground resource acquisition in forest ecosystems.

Root-order-associated variations in fine-root decomposition and their effects on soil in a subtropical evergreen forest

open access: yesEcological Processes, 2022
Background Despite the importance of root decomposition in predicting ecosystem responses to future climate change, the effects of branch order on root decomposition and the feedback to soil still remains poorly understood. Here we separated root samples

The Hierarchy of Protoxylem Groupings in Primary Root and Their Plasticity to Nitrogen Addition in Three Tree Species

open access: yesFrontiers in Plant Science, 2022
Protoxylem grouping (PG), a classification based on the number of protoxylem poles, is a crucial indicator related to other functional traits in fine roots, affecting growth and survival of individual root.

Some efficient seventh-order derivative-free families in root-finding [PDF]

open access: yesOpuscula Mathematica, 2013
The interest in efficient root-finding iterations is nowadays growing and influenced by the widespread use of high-speed computers. On the other hand, the calculation of derivatives is often hard, when the problems are formulated in terms of nonlinear ...
