| In vegetative propagation by means of root cuttings, the nutritional status determines the amount of carbohydrates, endogenous auxin levels, among other metabolites, fundamental for the root initiation and to the speed that rhizogenic events progress. An especial attention should be given to the nutritional status of the donor-plants, in order to better assist the nutritional demands by the adventitious rooting process. Although mineral nutrition and adventitious rooting are intimately related, the subject is rather difficult to study, sincethe later involves multiple steps and few studies have aimed to elucidate the relationship between the mineral nutrition and rooting phases. In this review, the phases of the rhizogenesis are highlighted and the role... |

| The objective of this work was to evaluate different densities of rootedproductivity and survival as well as the effects on production and survival of cuttings produced. We performed two separate experiments, one for each genetic material (C1 and C2) and were assessed three densities for clone C1 (88, 75 and 57 ministumps m-2) and two for clone C2 (104 and 78 ministumps m-2). Shoots we collected from the ministumps and they were used in making cuttings 6-10 cm long. Sampling was initiated in January 2011, ending in March 2011. The cuttings were planted in substrate composed of 50% vermiculite and 50% of rice hulls and subsequently they were conducted in following steps: greenhouse, shade house and field hardening. For both clones, the density with smaller... |
