Recoltons de bonnes et belles pacanes par le greffage des arbres de semis


, : Recoltons de bonnes et belles pacanes par le greffage des arbres de semis. Fruits Primeurs 12: 213-214

Pecans in Algeria are a heterogenous collection all grown from seed and of little value save for their appearance. Some effort should be made to work these over to selected varieties. Even quite old trees can be crown grafted and will bear useful crops a few years later. To prepare the tree the main branches are headed back in Jan. or Feb. to within a meter or less of the trunk, 1 or 2 of the smaller ones being left untouched as nurse branches to be progressively removed as the grafts develop. The headed trees are at once whitewashed against sunburn. The shortened branches are crown-grafted in March. The operation is not described, but emphasis is laid on the importance of a complete exclusion of air from the union by thorough waxing. The grafts are covered with waxed paper bags to reduce evaporation. As a precaution against wind and parched buds the new grafts are protected by twiggy branches fixed on the stock branches. The scions should be selected from healthy, well-budded 2-yr.-old wood. Selected material can be got from the Boufarik expt. station.
