WebIt is a matter of common observation that the critical day length of both long-day and short- day plants tends to fall within a range of 12—14 hours. Commercial flower growers can induce or delay flowering by controlling the photoperiodic and temperature conditions in glasshouses to meet the demands of the market. WebGardner and Loomis (1953) recognized three discrete phases in orchard- grass flowering, each with distinctive photoperiodic and thermal requirements: 1. Floral Induction: Production of the flowering stimulus (a chemical change in the shoot apex) in response to the cold (non-growth) temperatures and short days of autumn. 2. Floral Initiation: …
