Abstract
DORMIN (abscisin II) is present in the flesh and achenes of the mature hips of Rosa arvensis1; it is also present in R. rugosa and R. canina, and it has been suggested that its presence in both parts of the hip may be related to the onset and depth of dormancy in the mature embryo2. The inception of cell division in abscission layers suggests that this substance may also be concerned in more positive aspects of growth; the ability of dormin to induce a limited amount of parthenocarpic development in R. sherardii supports the idea.
