Fall: September is the ideal time to seed during fall as soil temperatures are still warm enough to allow for seed germination and ideal for the new seedlings to become established, says May.
1. Watch the soil temperatures. If it’s too cold, grass seed won’t germinate. If it’s too hot, the baby grass seeds will pop up, then quickly fry.
"Its high protein content can inhibit seed germination by desiccating emerging new roots," Gifford explains. "However, its effectiveness varies as it takes some time to build up in the soil and be ...
Seed that germinates in the fall can overwinter and then resume growing in early spring, giving foxtail barley a competitive advantage over many crops. Germination is inhibited by warm temperatures, and the seeds require a period of darkness for germination to occur. Foxtail barley is a shallow-rooted plant with germination occurring at soil ...
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 ...
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous. [9]

Bromus tectorum is an abundant seed producer, with a potential in excess of 300 seeds per plant; seed production per plant is dependent on plant density. Under optimal conditions, B. tectorum may produce 450 kg of seed per hectare (400 pounds per acre) with about 330,000 seeds/kg (150,000 seeds/pound). [ 10 ]
