DENDROLOGY

Topophysis is defined as the effect of the position on the plant of the propagule on the type of vegetative growth subsequently shown by the vegetative progeny. It can be demonstrates as I. cuttings from lateral shoot produce plagiotropic growth. II. cuttings taken from upright shoot produce orthotropic growth. III. cuttings from branches will always produce progeny with lateral growth. IV. in most species progeny with plagiotropic growth will recover as it grows.
