Diagnosing Random Angular Test Failuresg spacing and frequency of reseeding grass fields increases plant sensitivity to air pollution..The available data in air pollutant effects on reproduction in relation to the additional influence of other abiotic or biotic stresses is discussed.

Effects of air pollution on plants and vegetations,tants is approached by using more-dimensional no (-adverse)-effect surfaces. Possible ways of prevention or diminution of effects of air pollution on plants are looked for and strategies are developed for the achievement of air quality objectives in the future.

Free radicals and heavy metal tolerance,ted with peroxidation of the root cell membranes, there are no indications that metal toxicity would primarily rely on a disturbance of the cellular radical balance. It is uncertain whether the evolution of metal tolerance involves changes in the capacity of the cellular defence against radicals.

Ecological responses of macro- and microphytic algae to water pollution,stewater and manuring of pastures. Prolific algal growth may outcompete the aquatic macrophytes by reducing irradiance (Phillips . 1978) and by directly hindering photosynthesis by increasing pH and reducing the CO. content of the water (Simpson & Eaton 1986).

Common reed,on reed can occur in a wide range of environmental conditions, determined by a number of physical and chemical factors like oxygen, water, temperature, pH, macro- and micronutrients, and inorganic and organic contaminants.

,Erklärungsmodelle für Angststörungen, plants grow profited by the presence of mycorrhizas, while in heavily stressed situations only a few species grow, having (nearly) no mycorrhizas. Finally it is concluded that fairly much is known on the function of mycorrhizas for crop plants, but very little for natural populations.
