Abstract

<p>Chrysanthemum is a typical short-day plant and responds to shortening of daylength in the transition from vegetative to reproductive phase. The manipulation of daylength is widely used in the commercial production of chrysanthemum. In chrysanthemum, daylength and growth temperature affect the development of floral organs after the floral transition. Recent advances in molecular genetics have identified a florigen in model plants. Recently, an antiflorigen which inhibits flowering antagonizing with florigen has been found in chrysanthemum. This review summarizes the flowering regulated by daylength and temperature through the balance of florigen and antifl origen production in chrysanthemum.</p>
