Legumes are characterized as keeping stable nutrient supply under nutrient-limited conditions. However, few studies examined the legumes' stoichiometric advantages over other plants across various taxa in natural ecosystems. We explored differences in nitrogen (N) and phosphorus (P) stoichiometry of different tissue types (leaf, stem, and root) between N2-fixing legume shrubs and non-N2-fixing ...

F or normal growth and optimum production, fruit the quantities that they are in certain annual crops. Generally, nitrogen is the only macronutrient that must be consistently supplied to fruit trees in California. Under certain conditions, other nutrient deficiencies can develop. Toxicities can also become a problem. These will be discussed in the sections for individual nutrients. trees requir...

in this study, the effects of different types of hand plucking were studied on green leaf yield and black tea quality. bud and a leaf, bud and two leaves, bud and three leaves and bud and four leaves were the types of hand plucking. plucking was down on chine’s hybrid tea and clone 100 in fuman tea research station. shoots were plucked in flashing period regularly during three years. green leaf...

Plant leaf nutrient concentrations and resorption are sensitive to fertilization, yet their co-responses under different nutrient-limited conditions have not been well studied. We conducted a meta-analysis from global dataset of 43 reports, including 130 observations studies with plant nitrogen (N) or phosphorus (P) efficiency (NRE) (PRE), in response fertilization divided by the thresholds N:P...

Cymbopogon citratus (DC.) Stapf commonly known as lemon grass is used extensively as green tea and even as herbal tea ingredient across the world. Plants have the ability to uptake metals as nutrient from the soil and its environment which are so essential for their physiological and biochemical growth. Concentrations of these twelve trace elements, namely, Mg, Ca, Cr, Mn, Fe, Ni, Cu, Zn, Mo, A...

BACKGROUND AND AIMS The objective of this research was to characterize the physiology and cell ultrastructure of two soybean genotypes subjected to nutrient solutions with increasing concentrations of manganese (Mn) at two contrasting iron (Fe) concentrations. Genotypes 'PI227557' and 'Biloxi' were selected based on their distinctly different capacities to accumulate Mn and Fe. * METHODS Brad...

Developing and deploying cotton cultivars with high nutrient uptake, use efficiency and tolerance to nutrient related soil stresses is desirable to assist sustainable soil management. Genetic variation, heritability, selection response and quantitative trait loci (QTLs) were investigated for five macronutrients (P, K, Ca, Mg, S) and five micronutrients (Fe, Mn, B, Zn, and Cu) in a recombinant i...

Root-knot nematode, Meloidogyne incognita, is the major limiting factor in tomato production in many regions of the world including Ethiopia. For its management, different plant species (botanicals) are being tried in different forms as an alternative to nematicides. The nematicidal potential of baker tree (Milletiaferruginea), bitter leaf (Vernonia amygodalina), parthenium (Parthenium hysterop...

The barrier function of the human mammary gland collapses if challenged with cationic drugs, causing their accumulation in milk. However, underlying molecular mechanisms are not well understood. To gain insight into the mechanism, we characterized transport of organic cations in the MCF12A human mammary gland epithelial cells, using carnitine and tetraethylammonium (TEA) as representative nutri...
