Abstract:

Cuttage is one of the common methods in breed of Dahlia, but their rooting and survival rate exit obvious differences because of different medium and measures. In order to increasing the rooting and survival rate, we carry out this research. Under the former experiences and many years’ practices, we screen and get three idea medium and two methods, and then design six assembles to test. The study showed that perlite is the best medium, and “cuttage with soil” is the best measure. “Cuttage with soil” can solve and make up for the questions which caused by cuttage itself.
