| Abstract:
In the fruit orchard as well as in the forest tree seed orchard, the vegetative period of grafts - related to their previous juvenile period - is both a technical and commercial handicap. Juvenility in seedlings retards all breeding programmes, but the antagonism between growth and fruiting makes foresters reluctant to select or breed for shorter juvenile periods as advocated by fruit breeders. Juvenility is desirable for vegetative propagation and may reduce game damage. True rejuvenation seems possible, at least with respect to rooting ability. Long juvenile periods are seen as an adaptation to live in the high forest. Needs for research are indicated. | |
