The aim of this paper is to review the current knowledge on the uptake of mineral nutrients from foliar fertilization. Despite many studies carried out on mineral nutrient absorption by leaf tissues, many aspects of foliar fertilization are still unknown. At present, it is believed that such fertilization of plants is a valuable complement to the application of nutrients to the soil. Foliar fer...

The objective of the present study was to evaluate the phytonutrients, mineral composition, antimicrobial and hepatoprotective activities of leaf of Actinodaphne madraspatanaBedd (A.madraspatana). The content of β-carotene and lycopene in ethanol extract was determined by UV-Visible spectroscopy. The mineral composition of the leaf powder was determined by atomic absorption spectroscopy. The an...

Consumption of vegetables is one of the most important ways of providing the body with mineral elements. However, it is not clear how mineral elements are distributed in different organs of vegetables, especially vegetables grown in greenhouses. The distribution of mineral elements in the root and leaves of greenhouse spinach was determined using synchrotron radiation XRF, the results indicated...

Plants are extremely versatile organisms that respond to the environment in which they find themselves, but a large part of their development is under genetic regulation. The links between developmental parameters and yield are poorly understood in oilseed rape; understanding this relationship will help growers to predict their yields more accurately and breeders to focus on traits that may lea...

In ecological setting, sodium (Na(+)) can be beneficial or toxic, depending on plant species and the Na(+) level in the soil. While its effects are more frequently studied at high saline levels, Na(+) has also been shown to be of potential benefit to some species at lower levels of supply, especially in C4 species. Here, clonal plants of the major tropical C3 crop Theobroma cacao (cacao) were g...

background: the purpose of this study was to evaluate long-term changes in bone density profile among survivors of childhood acute lymphoblastic leukemia. patients and methods: this was a 5 year prospective study comprised of thirty-one survivors of childhood acute lymphoblastic leukemia with a mean age of 11.8 (4.6) years, who completed therapy at least 1 year previously (according to the all-...

We evaluated factors influencing the development of autumn red coloration in leaves of sugar maple (Acer saccharum Marsh.) by measuring mineral nutrient and carbohydrate concentrations, water content, and phenology of color development of leaves from 16 mature open-grown trees on 12 dates from June through October 1999. Mean foliar nutrient and carbohydrate concentrations and water content were...
