Older mature portions of the root system transport water and inorganic nutrients upward to the shoot system, and organic nutrients downward to growing portions of the root. The outer secondary tissues of mature roots restrict water and nutrient loss from the root into the soil, and help to ...

Design of UPFC controllers and supplementary damping controller for power transmission control and stability enhancement of a longitudinal power system a systematic approach based on the root locus method and pole assignment is developed to reach proper proportional-integral (PI) controller gains for the...
Efforts have been made in this regard, leading to a root system architectural taxonomy that defines the main roots classes present in nature: taproots, lateral roots, shoot-borne roots and basal roots; considering the origin of the root type [2]. There are also studies that aim to establish...
FS and PS were designed to compare the role of the full root system and split root system to induce nHRS. Leaves samples were collected during booting and anthesis to compare the role of nHRS at both growth stages. The data indicated that under PS treatment, ABA concentration was ...
shoot and roots. We also used qPCR to validate the activity of some genes selected from the microarray analysis in a dose-dependent magnetic field experiment. We found that the GMF regulated genes in both shoot and roots, suggesting that both organs can sense the GMF. However, 49% of the ...
Define Root stock. Root stock synonyms, Root stock pronunciation, Root stock translation, English dictionary definition of Root stock. n. 1. A root system of a plant, often with a portion of the stem, to which a shoot or bud is grafted. 2. See rhizome. A
The split-root system technique has been used to analyse plant biology for several decades, but woody plants have not received enough attention in this exp
Developmental processes that control root system architecture are critical for soil exploration by plants, allowing for uptake of water and nutrients. Conversion of the auxin precursor indole-3-butyric acid (IBA) to active auxin (indole-3-acetic acid; IAA) modulates lateral root formation. However,...
The specific objective of the present study was to investigate barley root growth under drought stress in a hydroponic system using PEG as osmotic stressor compared to sand pot experiments. To investigate impacts on the whole plant, correlations between the plant shoot mass under these controlled co...
