The Geoelectric Effect in Plant Shoots:

Journal of Experimental Botany, 1971
Incubation of Zea coleoptiles in 0-5 M mannitol totally inhibits growth and geotropic curva ture, but does not affect the development of the geoelectric effect. This pre-treatment also inhibits the curvature induced by the asymmetrical application of IAA to the apical end of decapitated vertical coleoptiles, but it does not prevent the IAA from giving ...

The Geoelectric Effect in Plant Shoots

Journal of Experimental Botany, 1970
The development of the geoelectric effect has been followed in Zea coleoptiles with a flowing solution electrode system, and its dependence upon auxin concentration gradients and aerobic metabolism assessed. A symmetrical source of IAA can effectively replace the coleoptile tip in allowing the geo electric potential to occur.

The Geoelectric Effect in Plant Shoots

Journal of Experimental Botany, 1972
In earlier papers Woodcock and Wilkins, and Hertz and Grahm reported measurements of the geoelectric effect (GEE) in Zea mays coleoptiles. While Woodcock and Wilkins attached contact electrodes to the coleoptile directly, Grahm and Hertz employed a vibrating-electrode technique that avoided touching the plant.

In vitro plant regeneration from callus of shoot apices in apple shoot culture

Plant Cell Reports, 2000
A new reliable protocol for the induction of adventitious shoot formation and plant regeneration from apple callus has been developed. High regeneration frequency was obtained with this method in four different genotypes (Jork9, M26, Gala and McIntosh) and callus maintained regeneration ability for several months.

Plant hydraulic conductance adapts to shoot number but limits shoot vigour in grapevines

Functional Plant Biology, 2014
The rate of shoot growth (vigour) in grapevines tends to decrease as the number of shoots per plant increases. Because the underlying causes of this relationship remain unclear, they were studied by variable pruning of field-grown, deficit-irrigated Merlot grapevines (Vitis vinifera L.).

Development of maize plants from cultured shoot apices

Planta, 1988
Excised shoot apices of maize (Zea mays L.), comprising the apical meristem and one or two leaf primordia, have been cultured and can form rooted plantlets. The plantlets, derived from meristems that had previously formed 7-10 nodes, develop into mature, morphologically normal plants with as many nodes as seed-grown plants. These culture-derived plants

Silica in Shoots of Higher Plants

1981
In the shoots of vascular plants, silica is deposited as amorphous silica gel, SiO2 · nH2O. It occurs in many plant families including the scouring rushes or horsetails (Equisetaceae), grasses (Poaceae), sedges (Cyperaceae), ginger family (Zingiberaceae), spiderworts (Commelina- ceae), nettles (Urticaceae), elm family (Ulmaceae), vervain family (Ver ...

Fluxes of atmospheric hydrogen sulphide to plant shoots

New Phytologist, 1989
summaryShort‐term exposure of maize, pumpkin, spinach and spruce to various atmospheric H2S concentrations resulted in high H2S fluxes to the shoots. In all species an almost linear relation was observed between flux and H2S concentration up to around 0.3 μl −1.

Embryonic shoot apical meristem formation in higher plants

Journal of Plant Research, 2002
The shoot apical meristem (SAM) is essential for organ formation in higher plants. How the SAM is formed during plant development is poorly understood, however. In this review, we focus on several recent studies that provide new insights into the mechanism of SAM formation during embryogenesis.

PREDICTING CHEMICAL ACCUMULATION IN SHOOTS OF AQUATIC PLANTS

Environmental Toxicology and Chemistry, 1991
Abstract Chemical exchange dynamics expected for diffusive transfer of a chemical between aqueous solution and plant shoots, and expected bioconcentration based on partitioning properties of the chemical, are explored by using a three—compartment model.
