Although inhibition of root elongation has been widely recognized as the most striking symptom of Al toxicity on plants (Clarkson, 1965: Foy, 1988), root growth characteristics such as total root length, root dry matter, and taproot
length, or the longest seminal root, when used to identify Al-tolerant cultivars in Al-toxic soil, often produce contradictory results compared with shoot growth measurements.
Decreasing stand density increased taproot
size and increased branching of alfalfa roots (Garver, 1922; Upchurch and Loworn, 1951).
Starch, Nitrogen, Soluble Protein and VSP Contents in Taproots
Membranes were incubated in antibodies raised to taproot
VSP (Cunningham and Volenec, 1996) diluted (1:10 000) in Tris-buffered saline (10 mM Tris-HCl, 150 mM NaCl) containing 1.
This reflected greater variability caused by fewer samples contributing to the mean (five taproots
and 30 sections compared with 25 to 35 taproots
and 150-195 sections).
Our first objective was to determine if there is a relationship between taproot
diameter and ability of rosettes to survive herbicide treatment.
Fibrous root systems are generally much more diffused and closer to the surface than the taproot
The two parents were not significantly different for specific RL nor for taproot
A `FaberCastell uni POSCA' marker pen, which contains orange-coloured water-based fluorescent paint, was used to highlight the live cotton taproots
Seedlings of perennial species varied in root system morphology; some resembled annuals whereas others had deep taproots
and high root/shoot ratios (Table 1).
You can move young plants readily; older plants have taproots
and can't be moved safely.
In the case of dandelions, curly dock and numerous other plants, their deep taproots
drew moisture from soils deep below the surface roots of plantain, lawn grasses and other shallow-rooted plants.
