A model is postulated to describe biomass dynamics in pastures that are grazed continuously throughout a limited growing season. It assumes that: rate...

Eighteen biotypes collected from different sites were grown in a common environment and seeds from these biotypes were grown in four experiments in co...

Material from single representative plants of perennial ryegrass, meadow fescue and a triploid [festucoid] hybrid between them was grown in small plot...

[Cf. FA 33, 3807]. The response of net photosynthesis (F), and stomatal resistance (rs) and mesophyll resistance (rm) to CO2 flux, to a stepwise seque...

The diurnal variation in leaf stomatal conductance of 3 canopy emergent trees (Hopea ferrea) was measured on 13 days over a 6-wk period (August-Septem...

Both species responded to increasing density by extreme plasticity and there was no density-induced mortality even at 3200 plants/m². In wheat the pla...

In a field experiment in central Sweden, shoots of 20-year-old Scots pine (Pinus sylvestris) were hand-pruned in 2 series, 1 with non-fertilized trees...

Seedlings and young trees of Pinus sylvestris were grown in outdoor fumigation chambers at 5 and 150 mu g SO2/m3 (approx.). The higher SO2 concn. redu...
