Yield and water-relation responses of soybeans to single and multiple periods of soil-moisture stress
… physiological and yield responses to water stress were studied in a movable weather (rainout) shelter facility at Ames, Iowa, during the summer of 1978. Soil-moisture deficits were induced in six combinations of three stress periods during reproductive growth to investigate the possibility …

Variation in Drought Tolerance Attributes Among Tepary Bean (Phaseolus acutifolius) Germplasm
… The germplasm was evaluated before and after the soil moisture stress treatment which was imposed on the trial by withholding water for 21 days. A 6 x 7 rectangular lattice design replicated three times was used for evaluating 42 genotypes. The results showed that prior to soil moisture stress, …

Root growth of wheat genotypes in hydroponics and soil in relation to water stress tolerance and grain yield
… in hydroponic culture predicts root growth in soil, and whether root size is associated with grain yield and with tolerance to soil moisture stress. Differences in root fresh weight (RFW), shoot fresh weight (SFW), number of roots longer than 40 cm, longest root length, and total root length …

Stable light isotopes in fauna as environmental proxies in the Southern African winter and year-round rainfall zones
… mean annual temperature (MAT), mean annual soil moisture stress (MASMS), mean annual potential evapotranspiration (MAPE), relative humidity (RH), summer aridity index (SAI), winter concentration of rainfall (WCR), moisture index (MI) and water deficit (WD).

Factors controlling the distribution and spread of bracken (Pteridium Aquilinum) in Scotland
… affect bracken in Scotland. The climatic, soil, vegetation and biotic characteristics of four sites in the bracken zone (west, south-west, north-east and south-east) are reviewed first. By comparisons of inter-site factors and bracken vigour at the sites, it is possible to formulate …

Dynamics of water, carbon, and nitrogen in forest and alpine tundra ecosystems in the Pacific Northwest and the Rocky Mountains of the U.S. under future climate change
… in the western U.S. will result in physiological stress on vegetation that is adapted to its native climate, and alter future dynamics of water, carbon, and nitrogen in these ecosystems; 2) other aspects of global change such as elevated atmospheric CO2 concentrations and an extended growing …

Ecology and niche characterization of the invasive ornamental grass Miscanthus sinensis
… of the commonly limiting resources of light and soil moisture. In order to better assess the risk of M. sinensis (and subsequently M. × giganteus) cultivation, we surveyed 18 naturalized populations across the east coast to characterize habitat preferences, population structure, and plant …
