The extractable activity of sucrose phosphate synthase was determined in etiolated seedlings of maize (Zea mays L.), soybean (Glycine max [L.] Merr.), and sugar beet (Beta vulgaris L.) following treatments of changing light quality. A 30-minute illumination of 30 microeinsteins per square meter per second white light produced a three-fold increase in sucrose phosphate synthase activity at 2 hou...

Late-summer starch accumulation in fine roots of poplars (Populus x canadensis Moench.) defoliated by gypsy moth (Lymantria dispar L.) lagged behind that in fine roots of undefoliated trees. If starch concentration declines with age, defoliation-induced changes in root system age structure could be partly responsible for this difference. To test this hypothesis, we measured fine-root starch and...

The pulp of the cocoa fruit still has not economically viable yet. Its potency to be processed into syrup is expected increase its value added. Local sugar from palm and canes traditionally utilized produce brown sugar. This study aimed make by utilizing local sources in West Sumatra with several variants (palm sugar, sugarcane, market white sugar). effects concentration on quality were also st...

The author and Van Slyke (5) have recently published a method for sugar determination in which the time required to decolorize a standard ferricyanide solution was used as a measure of the sugar content. The convenience which this method demonstrated in clinical work stimulated attempts to widen its range of usefulness by developing a micro modification. By carrying out the reaction in small te...
