The nematode fauna of 4 cropping systems were studied for 5 years in central Sweden. Plots were cropped as follows: barley with (B120) and without (BO...

Measurements were made during the winter of 1977/78 at the Welsh Plant Breeding Station of changes of leaf, stolon and root biomass, stolon length and...

Competition from weeds (Agropyron repens, Stellaria media, Poa annua and others) in the first growing season hastened foliage senescence and reduced b...

Except in the 2- to 3-month annual dry season, stomatal conductance was principally determined by incident irradiance; it was independent of shoot wat...

A measuring system for estimating the frequency distribution of irradiance within a plant stand is described. The system uses a distributed set of 32 ...

The relationship between the wt. of above-ground biomass/unit area (y) the number of plants/unit area and time can be expressed in terms of arbitrary ...

The buried viable seed content was determined for some leys and permanent pastures. Seeds of Poa annua were abundant under the leys but absent under t...

Seed germination in Agrostis capillaris, Holcus lanatus, Poa trivialis, Cynosurus cristatus and Festuca rubra was investigated in the dark at temp. ra...

Green roofs are novel ecosystems that are increasingly common in cities. While their hydrologic and energy saving benefits are well-established, green...

Presence or absence of buried seed was the major factor governing natural revegetation of a bulldozed disturbance in Alaskan tussock tundra. The viabl...
