Induction-Reversion Responses or, Low Fluence (LF) Responses

Examples include:

Light-sensitive seed germination;

Many seeds require light for germination (like lettuce), whereas others are inhibited by light (wild oats, Phacelia, Royal Paulownia). Phytochrome presumably stimulates GA synthesis/release which in turn, stimulates the mobilization of stored reserves
