"This period historically includes a higher chance of rainfall, which will help keep the soil moist, aid in seed germination, and provide enough daylight to ensure the grass thrives in enough time ...
Keep this in mind: You want the seeds to make good contact with the soil for improved germination rates. Sprinkle seed on the bare area, lightly working in into the first 1/8-inch of soil. Pat ...
It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...
In comparing different treatments, genotypes or species, the simplest type of growth analysis is to evaluate size of plants after a certain period of growth, typically from the time of germination. In plant biology, size is often measured as dry mass of whole plants (M), or the above-ground part of it.
Growing degree days (GDD), also called growing degree units (GDUs), are a heuristic tool in phenology.GDD are a measure of heat accumulation used by horticulturists, gardeners, and farmers to predict plant and animal development rates such as the date that a flower will bloom, an insect will emerge from dormancy, or a crop will reach maturity.
Anymore than that and the viability of seeds decreases over time. After two weeks of pre-chilling, little barley seeds go into dormancy, allowing little barley to overwinter and come back year after year. Seeds germinate best between 17 and 20 degrees C. The more mature the seeds, the better they germinate. [8]

Dormant seeds do not germinate in a specified period of time under a combination of environmental factors that are normally conducive to the germination of non-dormant seeds. [2] An important function of seed dormancy is delayed germination, which allows dispersal and prevents simultaneous germination of all seeds.
