Effect of container size and types on the root phenotypic characters of Capsicum
Capsicum genus comprised of several cultivars is considered as an important spice crop worldwide. Roots play a vital role in a plant to mine water from the deeper layers of the soil.

On the characteristic roots of matrices [PDF]
Let A = (a ij) be an nXn complex matrix. For i = 1, 2, , n and p > 0 define R(i, p) = I ait I P) l/p. It is well known [2 ] that the characteristic roots of A lie in the union of the disks (1) I aii,-z| < R(i, 1) (i = 1, 2, .. * * n). A. Brauer [3 ] improved this result by replacing these disks with the n(n 1)/2 ovals of Cassini (2) | aii,z IIai -z I <

A characteristic polynomial for rooted graphs and rooted digraphs
The paper investigates the characteristic polynomial \(p(G,\lambda)\) by concentrating exclusively on rooted graphs and digraphs \(G\). It is shown that when \(G\) is a rooted digraph, this polynomial essentially counts the number of sinks in \(G\). When \(G\) is a rooted graph, the authors give combinatorial interpretations of several coefficients and

Soil Characteristics Overwhelm Cultivar Effects on the Structure and Assembly of Root-Associated Microbiomes of Modern Maize [PDF]
Modern breeding primarily targets crop yield traits and is likely to influence root-associated microbiomes, which play significant roles in plant growth and health.

Modelling diverse root density dynamics and deep nitrogen uptake — a simple approach [PDF]
We present a 2-D model for simulation of root density and plant nitrogen (N) uptake for crops grown in agricultural systems, based on a modification of the root density equation originally proposed by Gerwitz and Page in J Appl Ecol 11:773–781, (1974). A
