Nucleic Acids of Chloroplasts and Mitochondria in Swiss Chard
Nucleic acids in young leaves of Swiss chard have been studied by light and electron microscope techniques. Leaf DNA has also been characterized by density gradient centrifugation and shown to contain a minor band of higher guanine plus cytosine (GC) content, presumably attributable to chloroplasts. The chloroplasts were faintly stained by the Feulgen reaction; radioautography demonstrated the ...
متن کاملQuality changes during storage of fresh-cut or intact Swiss chard leafy vegetables
Fresh-cut leafy vegetables have been gaining importance in the human diet both for their nutraceutical proprieties and low calories content. The preparation procedures for fresh-cut production and the storage system may lead to severe leaf damages that may affect leaf colour and induce shortened shelf life. The aim of this work was to study the leaf pigment changes in cut and whole Swiss chard ...
متن کاملAvron M. Photophosphorylation by Swiss Chard chloroplasts. Biochim. Biophys. Acta 40: 257-72, 1960
The article describes a detailed study for optimizing the conditions for preparation of chloroplasts from leaves of higher plants and of the reaction conditions for measuring photophosphorylation. Under the conditions specified, the world record rate.(which still holds) of light-induced ATP formation, approaching 2500 μ moles X mg chl-1 X hr-1, was attained. A simple assay system for following ...
متن کاملDissipation kinetics and residues analysis of pendimethalin in soil and maize under field conditions
Herbicides play an important role in the production of crops, but their residues may cause numerous human/environmental problems. Dissipation kinetics of pendimethalin and residues in soil, maize straw and cobs in winter maize under field conditions were studied by gas chromatograph-electron capture detector (GC-ECD). Dissipation followed the first order kinetics and accounted by a biphasic pat...
متن کاملPERSISTENCE OF ABAMECTIN RESIDUES IN/ON BRINJAL (Solanum melongena)
Spray application of abamectin (CHA 2062) was given twice to brinjal crop at 15 days interval at the recommended dose and double the recommended dose of 14.4 and 28.8 g a.i./ha during December, 2007March, 2008 to study its residue persistence. Initial residues of abamectin on brinjal from the two treatments were 0.202 and 0.815 mg/ kg, respectively. The residues persisted for 3 days from both t...
