Mineral nutrition of micropropagated plants
Aspects of the mineral nutrition of plants in in vitro cultures were studied in Delphinium 'Princess Caroline' and Hosta 'Fladspen Blue', two species with contrasting growth habits. Initially methods for accurately measuring mineral concentrations within gelled culture media using atomic absorption …

N₂ fixation, plant mineral nutrition and C metabolites in cowpea/maize cropping systems
… in the cropping system, it was found that mineral elements such as Ca, Mg, Cu, Zn and B occurred in significantly greater concentrations in the N₂-fixing legume compared to the cereal partner. However the concentration of soluble sugars and starch remained the same for both shoot and roots …

The Relationship Between Mineral Nutrition and Late-Season Bunch Stem Necrosis of Cabernet Sauvignon (Vitis vinifera L.) Grapevines
… produced little change in bloom-time petiole mineral concentration. Fertilizer treatments appeared to have no effect on BSN incidence, but the incidence of BSN was less than or equal 1% in the control plots each year. During the 1996 season at Winchester vineyard, bloom-time leaf petiole and …

Winter survival of bermudagrass (Cynodon sp.) as influenced by traffic, mineral nutrition, plastic covers, cultural treatments, overseeding and freezing in late-winter dormancy
… to determine the effects of: 1) traffic and mineral nutrition; 2) clear plastic covers and cultural treatments and; 3) overseeding and late winter freezing on bermudagrass winter survival. Four separate experiments were conducted on field cultured Midiron bermudagrass. Various regimes of …

The removal of lime from the ash of cow feces
… had occasion to conduct the analytical work in a mineral nutrition experiment conducted on dairy cattle. The principal constituent fed (and the one with which this paper is to deal) was lime. Rations high and low in lime were fed and the milk, urine and feces were analyzed to determine the calcium …

Effect of ammonium and nitrate on nitrogen fixation and mineral nutrition of ryegrass and uninoculated and inoculated clover grown separately and in association : A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Agricultural Science (Honours) in the University of Canterbury
The present investigation presents data on the growth and ionic composition of ryegrass (Lolium perenne L.), and uninoculated and inoculated white clover ( Trifolium repens L.) plants, grown in nutrient solutions containing either NH₄- or No₃-N. The effect of increasing nitrate concentrations on …

The dietary mineral content of Claytonia lanceolata corms from multiple populations across the Columbia Plateau region of North America
… have relied on foraged foods to obtain dietary mineral nutrition. Around 12,000 years ago, people began shifting towards a lifestyle of food production. The rapid shift in lifestyle significantly altered the human diet, and research suggests our genomes have had insufficient time to adjust. Due …

Oxalic acid production by the ectomycorrhizal fungus Hebeloma westraliensis and its role in the nutrient acquisition and growth of Eucalyptus diversicolor in calcareous soil
… review of mycorrhizal enhancement of the mineral nutrition of host plants. Particular attention was paid to the role of mycorrhizae in acquiring P from inorganic phosphates. Two experiments were designed to study a mechanism by which the ectomycorrhizal fungus Hebeloma westraliensis can …

CHARACTERIZATION OF TWO METAL TRANSPORTERS HMA3 AND NRAMP1 IN TWO ECOTYPES OF THE ZN/CD HYPERACCUMULATOR THLASPI CAERULESCENS COMPARED WITH ARABIDOPSIS THALIANA
… have proposed roles in ion homeostasis and mineral nutrition. The work here sought to determine if these transporters might have characteristics that suggest a role in heavy metal transport and tolerance in metal hyperaccumulating plants. These proteins are very well conserved among …

The Effects of Rootstock Selection and Carbon-based Fertility Amendments on Apple Orchard Productivity and Soil Community Ecology
… water loss, while improving soil structure and mineral nutrient availability. Orchard and pot-in-pot experiments were designed to study the following objectives: 1) determine the effects of integrated carbon-based fertilizer amendments on tree growth, productivity, and orchard soil fertility, 2) …

Influences of supraoptimal root-zone temperature on the medium solution and growth of woody nursery crops
… of high medium temperatures on the growth and mineral nutrition of selected woody plants and on the composition of the medium solution were studied. Medium temperature profiles were established for 3.8-liter black polyethylene containers exposed to solar radiation under Virginia nursery …

The Effect of Dietary Manganese on Growth, Reproductive Performance, and Manganese Status of Beef Heifers
Three trials were conducted to examine the effects of dietary manganese (Mn) on growth, reproductive performance, and Mn status of beef heifers. In Experiment 1, 80 Angus and Simmental heifers, approximately 10 mo of age, were supplemented with 0 (control), 10, 30, or 50 mg Mn/kg DM from MnSO₄ in …

Mineral requirements of selected species of aquatic hyphomycetes
This study was undertaken to investigate the mineral nutrition of aquatic Hyphomycetes by determining the mineral requirements of several species. On the basis of rapidity and renroducibility of growth, four species were selected, These were Heliscus lugdunensis Webster (Nectria lugdunensis …

Alocação de fotoassimilados e nutrientes em folhas e frutos de cafeeiro em diferentes altitudes de cultivo
Em regiões de maior altitude observa-se que o cafeeiro leva maior tempo para completar o seu ciclo. Em função disso, é possível que o pico de exigência nutricional em cafeeiros plantados em regiões de maior altitude seja mais tardio. Desta forma, as épocas e intervalos entre as práticas de adubação …

Crescimento e acúmulo de nutrientes em bucha vegetal (Luffa cylindrica)
As plantas possuem, em média, 5% de nutrientes minerais na matéria seca, porém as diferenças de acúmulo desses nutrientes são grandes entre espécies e as quantidades totais exigidas por uma cultura dependem da produtividade. Paralelamente, a absorção de nutrientes varia de acordo com a fase de …
