Modelling diverse root density dynamics and deep nitrogen uptake — a simple approach [PDF]
, 2009 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

Effects of some plant growth promoting rhizobacteria (PGPR) on rooting of grapevine rootstocks
Acta Agrobotanica, 2013 In this study. effects of topical applications of two plant growth promoting rhizobacteria (PGPR) strains and their combination (Bacillus BA16, OSU142 and BA16+OSU142) on the rooting of 41B and Rupestris du Lot rootstocks were investigated. The results

Root Vertex Valency Distributions of Rooted Maps and Rooted Triangulations
European Journal of Combinatorics, 1994 We obtain the asymptotic distributions of root vertex valencies for rooted maps and rooted triangulations on general surfaces. We show that the asymptotic distributions are independent of the surface.

A longitudinal study of the effects of providing straw at different stages of life on tail-biting and other behaviour in commercially housed pigs [PDF]
, 2011 Tail-biting (TB) is a welfare concern. Recent studies indicate that early provision of straw may help prevent TB, however, many of these studies were carried out on small groups of pigs and may have limited applicability to commercial farms.

"GALVANOTROPISM" OF ROOTS [PDF]
Journal of General Physiology, 1927 1. New experiments, made in such a way to eliminate as completely as possible products of polarization and the migration of such products when formed, have shown that the exhibition of galvanotropic curvature in roots is mainly dependent upon such products, since no curvature appears when they are excluded. 2.

Effects of different rooting substrates and rooting growth enhancers on the rooting of Ficus Benjamina cuttings [PDF]
, 2013 The species of the Genus Ficus are ornamental plants in which rooting percentage is lower than in other plants. This is why we aimed, in our experiment, at multiplying this species using different rooting substrates and several rooting growth enhancers ...

مجلة مركز بحوث التقنيات الاحيائية, 2007 Nodal explants of difficult-to-root Gordal olive were cultured on half-strength OM medium after surface sterilization with 15% NaOCl for 20 minutes. The in vitro-proliferated shoots were then submitted for 25 days to rooting trials including various ...

On root posets for noncrystallographic root systems [PDF]
Mathematics of Computation, 2014 We discuss properties of root posets for finite crystallographic root systems, and show that these properties uniquely determine root posets for the noncrystallographic dihedral types and type H

Adventitious rooting of detached Arabidopsis thaliana leaves
, 2012 Arabidopsis thaliana Heyhn is a model species in biochemical, physiological and molecular studies for which a plethora of mutants is available. This work aimed at developing a system for rooting of detached leaves, and evaluating time course of several ...
