Ploidy level analysis for induced polyploids of R. fortunei.

Ploidy Level	No. of Evaluated Plants	Peak Value
Diploid	405	25.26 ± 1.08
Tetraploid	69	48.92 ± 1.81
Octoploid	29	94.94 ± 2.44
Chimera	37	25.25 ± 1.33, 52.51 ± 2.01 a

^a These two mean values represented two main peaks detected in chimera plantlets. The test for each sample was repeated three times and mean peak value of each sample was firstly calculated based on the three repeats, and then averaged for diploids, tetraploids, octoploids and chimeras, respectively.
