Study on Dwarfing Effects of Paclobutrazol(PP333) to Phlox paniculata
摘要
Abstract
[Objective ] The aim was to study the effects of PP333 on growth and development of Phlox paniculata , and explore the best dwarfing methods. [Method] Phlox paniculata was treated with the water solution of 0,200, 400, 600, 800, 1 000 mg/L PP333 by spraying their leaves and irrigating the potted soil, and then determined and compared the plant height, leaf length, leaf width, leaf thickness, flower diameter, scape length, scape crude number of flowers. [Result] PP333 had dwarfing effects on plant height. The effects of spraying the leaves was much greater than that of soil irrigation. All treatments restrained the length of scape obviously, and various effects were noted in the flower diameter, scape crude and number of flowers. The optimum dwarfing treatment for Phlox paniculata was the application of 600 mg/L on potted soils. This treatment not only dwarfed the height of plants significantly, but also increased the scape crude and number of flowers. [ Conclusion ] The study provides a guidance for applying PP333 in dwarfing Phlox paniculata.关键词
