  • The effects of localized heating and disbudding on cambial reactivation and formation of earlywood vessels in seedlings of the deciduous ring-porous hardwood, Quercus serrata (33 citations)

In his most recent research, the most cited papers focused on:

  • Botany
  • Ecology
  • Gene

Ryo Funada mainly focuses on Botany, Xylem, Dormancy, Tracheid and Deciduous. His work in the fields of Cambium overlaps with other areas such as Water transport. His research in Cambium intersects with topics in Chamaecyparis pisifera, Chamaecyparis, Cell morphology, Phloem and Evergreen.
