Willow (Salix spp.) is currently being researched as a source of biomass energy in Canada. However, it is not certain whether afforestation with willow plantations will enhance or diminish soil C storage and nutrient availability. Trees are known to have pronounced effects on biologically mediated nutrient cycling processes which can increase nutrient availability, but willows are known to be n...

In order to determine calcium (Ca), magnesium (Mg) content and total antioxidant capacity (TAC) of seminal plasma in buffalo and to study their associations with the semen characteristics, 54 semen samples were collected from 10 buffalo bulls; semen quality was evaluated, seminal plasma was then harvested by centrifugation and its Ca and Mg content were estimated and its TAC determined. The Ca ...

In enteric synaptosomes of the rat, the role of voltage-dependent Ca(2+) channels in K(+)-induced VIP release and nitric oxide (NO) synthesis was investigated. Basal VIP release was 39 +/- 4 pg/mg, and cofactor-substituted NO synthase activity was 7.0 +/- 0.8 fmol. mg(-1). min(-1). K(+) depolarization (65 mM) stimulated VIP release Ca(2+) dependently (basal, 100%; K(+), 172.2 +/- 16.2%; P < 0.0...

Objective: Evaluate the nutrient concentration at foliar level of chrysanthemums grown in tezontle sand using three concentrations Steiner Universal Nutrient Solution.&#x0D; Design/Methodology/Approach: A completely randomized design was used, each treatment represented a solution and had 11 repetitions, study variables were: nutrients: N, P, K, Ca, Mg S, plant height (AP), stem diameter (DT), ...

The expansion of crop productivity such as watermelon can be reached by providing adequate nutrition in quantity and when plants need it most. It is known that well-nourished better resist biotic abiotic stresses, being determinants for more sustainable management. In this sense, the objective present study was to evaluate plant growth, rate nutrient absorption, proportion estimate exported nut...

In this study, the mineral contents of bread with boiled grape, date, carob and mulberry fruit juices at five different concentrations were determined. The fluctuations of B and Cu contents in bread with pekmez (molasses) were determined between 4.10 to 4.49 mg/kg and 2.74 and 3.34 mg/kg respectively. Ca, Mg, K, P and S were the main macro-elements of bread samples. The highest values of Ca...

background and objectives: availability and uptake of mineral by explants are recognized as being important in tissue culture. the limiting factor for maximum mineral uptake and optimum growth is that minerals are not enough available to the explants. there are the inter-relationships between plant growth, mineral uptake, medium water potential, and mineral movement through the medium. plantlet...
