The Blossom Biology Of Ground-grow Chrysanthemum And Regulation Of Flowering

AbstractGround-grow Chrysanthemum is a new variety group. For studying and popularizing it, this paper studies several aspects: l.The blossom biology of Ground-grow Chrysanthemum; 2.The trends of growth and flowering; 3.The effect of illumination ~. cultivation methods and chemical reagents to Ground-grow Chrysanthemum.The results show as follows: l.The process of flower bud differentiation of Ground-grow Chrysanthemum is finished under the long days and higher temperature, which includes two stages of inflorescence differentiation and floret differentiation. 2. The flower bud development of Ground-grow Chrysanthemum conforms to the Logistic Curve while the sunshine gradually shortening. 3. The growth of Ground-grow Chrysanthemum also conforms to the Logistic Curve. When the flower bud differentiates, the plants grow luxuriantly. 4. With the postponement of cutting time, flowering time are delayed for a short time. 5. Replenishing illumination has no influence on some varieties but it enables some other varieties to flower in spring. 6.The combination treatment of shortening illumination and pinching can?t change the florescence. 7. The chemical reagent that can promote plant growth has significant effect on some varieties growth and no effect on anthesis. 8. Pinching in right time can postpone the growth and flowering of Ground-grow Chrysanthemum for a short time.The blossom biology and some cultivation methods of regulating flowering are studied in this paper. This paper can provide basis for making a thorough investigation and studying the year-round production of Ground-grow Chrysanthemum.
