| Abstract/Contents: | "Stress reduces crop growth on nearly all arable land on earth (Solh, 1993) and severely limits agricultural productivity (Boyer, 1982). Perennial forages are grown in many different environments and must endure stresses not normally encountered by annual crops such as repeated defoliation by machines and surviving seasonal extremes in climatic conditions during several years. Forage crops account for 60-90% of feedstuff input for animal production systems (Barnes and Baylor, 1994). Rarely is the abiotic or biotic environment optimum for growth of perennial forages. Indeed, stress may be a regular feature of a particular environment. Stress has been defined as 'any factor that decreases plant growth and reproduction below the genotype's potential' (Osmond et al., 1987). Abiotic stresses include water deficit, temperature extremes, nutrient imbalances or deficiencies, light extremes, and soil factors (e.g. salinity and pH). There are several reviews on various aspects of the general topic of abiotic stress in plants, particularly in grain crops and plants grown in extensive systems (Jones et al., 1989; Alscher and Cummings, 1990; Fowden et al., 1993; Bohnert et al., 1995). We chose to limit the scope of this review to perennial forages because of limited coverage in previous reviews. We focus on defoliation (primarily machine harvest, not herbivory), low-temperature, water-deficit, nutrient, and salinity stresses and discuss the manifest- ations of these stresses at the whole-plant and organ level, examine the cellular bases of stress reactions, and explore the genetics of abiotic stress in relation to plant breeding for development of more stress-resistant germ plasm. We have attempted to highlight the most recent research and refer to the pertinent, in-depth reviews in each appropriate sections." |
