Definition
- [Lawrence Pomber] Seed germination is a crucial phase in the establishment and maint› of natural populations of\ \ plants. The dry seed is characterized by a low state of metabolism capable ofwithstanding extreme\ \ variations in its environment. Hydration of the seed is often all that is required to initiate an\ \ intricate and interlocked sequence of anabolic and catabolic processes essential for germination and\ \ growth. At this time, the seed is extremely vulnerable to environmental stress... , "[Bahman Shafii] Seed germination is a complex biological process that is influenced by various environmental and\ \ genetic factors... , "[Emilio Cervantes] Seed germination is a model system for the analysis of plant development. Cell elongation and\ \ differentiation processes are under the control of hormones and submitted to the influence of\ \ environmental factors. Hormones (abscisic acid, auxin, gibberellic acid, ethylene and others)\ \ interact with each other as well as with diverse components of cell metabolism... , "[F. Abbassi] Seed germination is an important phase of plant development during which soil water availability is\ \ crucial. Salinity can affect seed germination in two ways: 1) Change of osmotic potential of\ \ available water, 2) toxicity effects. In this experiment, interactive effects of salinity and water\ \ deficit on germination criteria of two species of A, littoralis and A. logopoides were studied in a\ \ factorial design with completely randomized arrangement and four replications...
