Ontogenetic changes in potassium transport in xylem of tomato
Physiologia Plantarum, 1982The influence of plant ontogeny on xylem exudate K+ concentrations and K+ transport to the shoot was studied in both nutrient‐solution and field‐grown tomato plants (Lycopersicon esculentum).K+ concentrations in xylem exudate from decapitated plants decreased during tomato plant development from a high of 12 mM to a low of 5 mM.

THE TRANSPORT OF AUXIN AND REGENERATION OF XYLEM IN OKRA AND PEA STEMS
American Journal of Botany, 1970Internodes were isolated from okra and pea plants grown from seed under controlled conditions. Isolated internodes were treated apically or basally with IAA‐C 14 or 2,4‐D‐C 14 and several vascular bundles were severed in the middle of the internodes ...

Waterlogging affects nitrogen transport in the xylem of soybean
Plant Physiology and Biochemistry, 1999Abstract Transfer of nodulated and non-nodulated plants grown in vermiculite to hydroponic culture without soil was used to study waterlogging and nitrogen transport in the xylem of soybean. Non-aeration, aeration or aeration with nitrogen gas were used to obtain different levels of oxygen in the culture solutions.

Effects of water stress on phosphorus transport to the xylem
Planta, 1968Tomato plants were treated for one hour in nutrient solutions at-10.4 atm. Roots were excised, transferred to solutions at-0.4 atm and put into a pressure chamber to induce rates of water flow similar to those in transpiring plants.

Nitrogen Compounds Transported in the Xylem of Sugar Cane
Australian Journal of Plant Physiology, 1976Microcapillary tubes were inserted directly into xylem vessels of leaves and stalks of sugar cane (Saccharum spp.) to determine the form in which nitrogen is translocated from the roots towards the leaves. On a low nitrogen regime, the xylem fluid of both sugar cane and related species and genera contained nitrogen dominantly in the amino form. Nitrate

Water transport in xylem conduits with ring thickenings
Plant, Cell & Environment, 1996ABSTRACTHelical or annular wall thickenings are not only present in protoxylem, but may also he a feature of the tracheids or vessel elements of secondary wood. The frequency of their occurrence tends to be a function of climatic factors and conduit diameter.

Transport of copper and manganese to the xylem exudate of sunflower
Plant, Cell & Environment, 1979Abstract Absorption of copper and manganese by sunflower roots from solution cultures of varying composition was followed by measuring the concentrations of the metals appearing in whole roots, root cell sap and xylem exudate. Total copper in the fibrous roots was linearly related to the concentration of copper in the external solution but the ...

Transpiration Mechanism of Capillary Transport in the Xylem of Plants
Ukrainian Journal of Physics, 2014The capillary transport of the aqueous solution of mineral salts in the xylem of plants owing to the transpiration process has been considered. By analyzing the balance of driving forces (capillary forces, gravity forces, and viscous friction), a differential equation describing the liquid flow in the xylem consisting of capillaries with varying cross ...
