Introduction Britain is a trading nation, exporting some 23% of its GDP which compares favourably with Germany and France at just below this figure, and perhaps rather surprisingly for some of you well ahead of the USA and Japan each of which have ab
Fructans polymerised and depolymerised in the internodes of winter wheat as grain-filling progressed

Carbohydrates soluble in 70% (v/v) ethanol were the major causes of the changes in the dry matter of the three internodes below the peduncle of a crop of winter wheat grown in Yorkshire, U.K. The concentration of soluble carbohydrates reached a maxim

SUMMARY In the first six leaves of plants of Allium cepa L. cv. Creamgold grown from seed, the carbohydrate content per unit fresh weight within the leaf is highest in the leaf base and lowest at the tip. Soluble protein content is highest at the lea

Fructan polymers were found in the 80% ethanol extract of epidermal strips of Allium cepa L. These carbohydrate polymers were detectable in epidermis held in darkness in the presence of abscisic acid, but virtually disappeared in the presence of KCl

Sucrose: sucrose fructosyltransferase and fructan:fructan fructosyltransferase were isolated from the inner leaf bases of bulbing onion plants (Allium cepa) and separated by gel filtration on Bio-Gel P-150. Sucrose:sucrose fructosyltransferase produc

Enzyme preparations from bulbing onion plants contained sucrose: sucrose fructosyltransferase and fructan hydrolase activities. Enzyme activities were highest in the leaf bases. Fructosyltransferase activity increased from the outer to the inner leaf

SUMMARY The non-structural carbohydrate content of individual leaf bases of onion bulbs was determined, and confirmed the presence of glucose, fructose, sucrose and a series of fructans as the only components. The fructans decreased in concentration

SummaryChanges in percentage dry weight and in carbohydrate levels and distribution were followed in Golden Brown Lockyer onion bulbs for three months at storage temperatures of 4°, 15°, 25° and 37°C. The percentage dry weight within the bulbs in

IAA oxidase/peroxidase active fractions were separated using concanavalira A-sepharose into glycoprotein and raongiycoprotein fractions. No IAA oxidase peak was separable from peroxidase activity. The development of these fractions were followed in p

SUMMARY In Allium cepa (cv. Creamgold), A. cepa (cv. Bunching Onion), A. porrum (leek) and A. sativum (garlic), fructans were the only nonstructural carbohydrates detected apart from glucose, fructose and sucrose. No starch or members of the raffinos
