Radioactive bicarbonate was pulse fed to blades of Macrocystis pyrifera (L.) C. A. Ag. and the movement of the 11C-labelled photoassimilates was monitored in vivo using an externally mounted array of Geiger-Muller detectors. Results of experiments co

11C fed to leaves as 11CO2 was used to study the dynamics of short-term translocation of photosynthate in Helianthus. As in 14C studies small amounts of tracer were often detected in the stem close to the fed leaf in the first 5 min, followed by a la

Simultaneous measurements of electrical resistance (or impedance (Z)) and water potential have been made on avocado Perseaamericana Mill. in the laboratory and on white spruce Piceaglauca (Moench) Voss in the field.A significant correlation was found

A technique has been developed to biosynthesize a water-soluble extract of 11C-labelled photosynthate high in [11C]sucrose. The extract can be produced in less than 1 half-life (20 min) and is of high activity. When 11C-labelled extract was fed to th

SUMMARY Electrical impedance monitoring techniques appear to be useful in tracing the effect of cooling or desiccation upon the thallus of Fucus vesiculosus and Ascophyllum nodosum. These algae were found to be remarkably resistant to injury from fre

This, paper reviews five premises which underlie the simple Münch-type pressure-flow mechanism of sugar transport in plants from source to sink. The validity of each of these has been found experimentally to be in doubt in functioning sieve tubes, b

Electrical resistance in young balsam fir (Abiesbalsamea (L.) Mill.) trees was inversely (nonlinear) correlated with specific volume increment, total foliar biomass, and the combined weight of the current and 1-year-old foliage. These relationships w
