Kinetin-induced expansion of lettuce (Lactuca sativa) cotyledons and inhibition of root are accompanied by parallel changes in protein nitrogen. However, during its inhibition of the longitudinal growth and water uptake of hypocotyl and pea (Pisum sativum) epicotyl sections kinetin markedly stimulates protein synthesis. Kinetin seems to separate auxin induced effects on protein synthesis and wa...

The effects of a series of concentrations of ethylene (10, 20, 40, to 10,240 nl/l) on elongation, diameter, and geotropism of the stems and roots of etiolated seedlings of Pisum sativum L., Arachis hypogea L., Phaseolus vulgaris L., and Gossypium hirsutum L. were measured or observed. Of the 24 possible responses, 4 were unaffected at the concentrations used, 5 were affected slightly, and the r...

This study investigated the chemical grafting of a single-layer poly(vinyl alcohol) (PVOH) film. The effect of the grafting parameters (grafting time, grafting temperature, and concentration of fatty acid chloride) on the hydrophobicity of the film surface and the film solubility were evaluated. The PVOH substrate film (cold-water soluble at 20°C) was manufactured by flat extrusion and had a th...

: a new fibrous adsorbent was prepared by grafting acrylic acid /acryl amide (aa/aam) co-monomers onto poly(ethylene terephtalat) (pet) fibers. the resulting sorbent has been characterized by fourier transform infrared spectroscopy (ft-ir), thermo gravimetric analysis (tga), scanning electron microscopy (sem) and elemental analysis and studied for the preconcentration and determination of trace...

In a series of Polynesian pearls collected after short cultivation periods, early post-grafting mineral deposits were characterized by high resolution synchrotron-based X-ray fluorescence with unprecedented accuracy. Morphological patterns and elemental composition are correlated through simultaneous imaging processes. Evidence that aragonite calcite occur in neighboring units during the earlie...

Abstract The objective of this work was to evaluate air layering, cutting, and grafting, with different indolebutyric acid (IBA) rates, for the vegetative propagation Eugenia involucrata. Air layering carried out two consecutive years five IBA rates. Cutting tested woody herbaceous cuttings, using four in three seasons. grafting methods – cleft graft splice were For trials experimental designs ...

heparin- induced thrombocytopenia (hit) is an antibody mediated adverse effect of heparin therapy which is classified into two subtypes, hit i which is non-immune, spontaneously reversible thrombocytopenia and; hit ii which is an autoimmune-mediated adverse effect of heparin therapy. in this case report, we described a 65-year old male patient with hit ii after coronary artery bypass grafting. ...

LetX be a closed oriented hyperbolic surface and γ a simple closed geodesic, which is short on X. We show that the iterated grafting grtγgrsγX is close to the grafting ray gr(s+T )γX in the Teichmüller metric, where the bounds depend on the length of γ only. Using this result, we show that the holonomy lifts gr2πγgrtγX of a grafting ray all lie in a r-tube around the ray grtγX and the rays grtγ...

Filipin, a polyene antibiotic known to induce leakage of materials from various cells, depresses K(+) and NO(3) (-) uptake in etiolated pea epicotyl segments. Filipin concentrations which strongly reduce K(+) influx have little effect on efflux; however, high concentrations enhance K(+) efflux. Filipin has no effect on respiration rates or cell electropotentials; its action is presumed to be on...

Changes in cell wall polysaccharides and mechanical properties of the cell wall were examined during IAA-induced elongation growth of excised azuki bean epicotyl segments under different growth conditions. Sucrose promoted IAA-induced cell elongation, but had very little effect on IAA-induced cell wall loosening. In the absence of sucrose, the amount of galactose in the cell wall decreased duri...
