| Abstract:
An “ideotype” describing a vase-shaped crown architecture suited for fruit production was developed to be applied to young grafted chestnuts. The experimental trials took place in nursery, in the field and in the wood, taking into account the type of rootstock and the methods of grafting and pruning to obtain the crown ideotype. A free stem height of about two meters is required to achieve the crown ideotype. In intensive chestnut cultivation, such a height was reached in two years since grafting for field seeding and in three years for one-year-old container seedling rootstocks. The type of rootstock resulted the most important factor, as it affected the height of grafting point, while the grafting methods were of secondary importance for their limited differences in scion survival and growth. Bud graft is recommended as it required limited pruning work. | |
