| Outline of Final Research Achievements |
We investigated the cultivating conditions that affect the number of petals in double flowers and the petal size in Eustoma. High temperaturejust prior to the petal initiation stage in the reproductive phase reduces the number of petals. This phenomenon applies to large varieties in Eustoma grandiflorum.Benzyladenine application as well as low temperature condition resulted in the increased number of petals. These effects were synergistic.
The petal size was influenced by the temperature condition during the reproductive phase. The analysis suggested that the genetic factor causing varietal differences of petal size contributes to the change of petal size due to temperature change.
