Dynamics of the uptake of nutrient elements from the medium of in vitro cultured apple rootstocks

open access: yesInternational Journal of Horticultural Science, 1999
Cation uptake of J-TE-F apple rootstocks propagated in vitro was studied by the analysis of culture medium. Test-plants were grown on liquid medium under different light regimes. Samples for tests were taken twice a week.

Vitis vinifera L. Diversity for Cations and Acidity Is Suitable for Breeding Fruits Coping With Climate Warming

open access: yesFrontiers in Plant Science, 2020
The selection of grapevine varieties is considered to be the smartest strategy for adapting the viticulture to climate warming. Present knowledge of the diversity of grape solutes known to be influenced by temperature is too limited to perform genetic ...

Phosphazene Cations

open access: yesInorganic Chemistry, 2006
Cations derived from (NPCl2)3, hexachloro-cyclo-triphosphazene, the weakly basic precursor of phosphazene polymers, have been prepared using strongly electrophilic reagents based on carborane anions. N-protonated, N-methylated, and N-silylated adducts of (NPCl2)3 have been isolated and characterized by X-ray crystallographic and spectroscopic methods ...

Calcium-Rich Steel Slag as a Reactive Capping Material: Effects on Hydraulic Conductivity and Nutrient Attenuation in Cohesive Intertidal Sediments

open access: yesJournal of Marine Science and Engineering
Fine-grained intertidal sediments are typically characterized by low hydraulic conductivity and high nutrient loads, conditions that hinder biogeochemical recovery and exacerbate eutrophication.

Wood Nutrient-Water-Density Linkages Are Influenced by Both Species and Environment

open access: yesFrontiers in Plant Science, 2022
Tropical trees store a large amount of nutrients in their woody tissues, thus triggering the question of what the functional association of these elements with other wood traits is. Given the osmotic activity of mineral elements such as potassium, sodium,
