Leaf expansion was investigated in 10 ecotypes of Lolium perenne and 7 of Dactylis glomerata. Seasonal sowings revealed a regular cline in relative ra...Read more
Measures of trait variability, in particular fluctuating asymmetry (FA), have been proposed as biological tools for monitoring environmental quality, ...Read more
The time course of changes in the quantity of Calluna leaves and wood were measured during 1971 and an analysis of the data used to derive the seasona...Read more
The relative rate of increase of leaf area per plant was measured in Vicia faba from May to August. In the early stages of growth, until the leaf area...Read more
A seed drill with 2 adjacent spouts blocked was used to sow winter wheat so that there were rows (a) 18 cm apart, (b) 18 cm from the next row on one s...Read more
Theoretical analysis of a simple model, in which tree growth in even-aged stands is calculated as the product of unit leaf rate (E, increase in plant ...Read more
The relationship between leaf conductance and environmental variables was examined during two summers in 22-year-old Shamouti orange trees. Soil water...Read more
A technique for measuring photosynthetic rates of attached leaves using 14CO2 was compared, in a field crop of barley, with a non-destructive method w...Read more
Describes a method for estimating the income of K, Mg, Ca, P and Na to a woodland ecosystem in the airborne particles caught by the tree canopy, and g...Read more
