Outline of Final Research Achievements

Root climbers (Schizophragma hydrangeoides and Hydrangea petiolaris) use trunk tree face. The supporting host preference was decided by a difference of the distribution for the light environment of the forest floor until supporting host arrival.

The creeping shoot of Schizophragma hydrangeoides showed stronger negative phototropism with growth. On the other hand, in the phototropism of a light period and the dark period, Trachelospermum asiaticum was not seen in the clear difference and produced the phototropism of the creeping shoot without the growth. There was the negative phototropism of at least two kinds of mechanisms in creeping shoot of root climber.
