摘要
在栽培时间和栽培措施相同的情况下,通过对大丽花的"植株高度"、"开花时间"、"花径大小"之间相关性的研究,得出以下结论:(1")植株高度"与"开花时间"有明显的相关性,即大多数矮型品种开花相对较早,大多数高型品种开花相对较晚。(2")花径大小"与"植株高度"有一定的相关性,即在高型品种中,大花所占的比例相对较多,小花所占的比例相对较少;在矮型品种中,小花所占的比例明显增多,大花所占的比例有所减少。(3")花径大小"与"开花时间"无明显的相关性,即大、中、小花型的品种基本上是均匀地分布于早、中、晚花型的品种当中,而无明显的倾向性。
The relationships among the height of plant, ied under the same cultivation time and method. There the time of bloom and the diameter of flower were stud- is obvious relationship between the height of plant and the time of blooming. Most short types bloom earlier, and many high types bloom late. There is certain relation- ship between the diameter of flower and the height of plant. The big flower is more than the small one in the high types, but the small one is more than the big one in the short types. In addition, there is no clear relation between the diameter of flower and the time of blooming. No matter the variations are big, middle or small types, they are evenly distributing over earlier or later blooming types.
