The determination of tocopherols and isoprenoid quinones in the grain and seedlings of wheat (Triticum vulgare).

چکیده
1. A comparison is made of several procedures for the extraction of tocopherols and isoprenoid quinones from plant tissues. 2. Gradient-elution column chromatography on acid-washed alumina efficiently separates the isoprenoid quinones and tocopherols into groups that can then be assayed spectrophotometrically or, with the tocopherols, separated into their individual components and determined by gas-liquid chromatography. 3. This improved analytical procedure was used to study the distribution of the tocopherols and of ubiquinone in the ungerminated wheat grain.

Ethylene evolution from etiolated barley (Hordeum vulgare), wheat (Triticum aestivum), and rye (Secale cereale) seedlings during coleoptile growth followed a rhythmic pattern, with a period of about 16 h for barley and wheat and 12 h for rye seedlings. Leaf emergence disturbed the established rhythm of ethylene evolution.

متن کاملPhytotoxicity effects of soil amended residues of wild barley (Hordeum spontaneum Koch) on growth and yield of wheat (Triticum aestivum L.)
Wheat (Triticum aestivum) growth and yield are depressed by physical and chemical interference of weeds. Recently, wild barley (Hordeum spontaneum) population has increased in wheat fields of many provinces of Iran. Since, little is known about the allelopathic effects of wild barley residues in soil, greenhouse studies were conducted to examine the effects of soil amended residues of wild barl...
