Efeito de hormônios vegetais sôbre o enraizamento de estacas de amoreira, plantadas em estufins, em posição normal e invertida

In the present paper the results are reported that were obtained by the utilization of plant hormones on cuttings of Morus alba of the variety Catania 1, which were planted in propagator covers with plastic covers, obeying two planting systems, the reverse and the normal one. The reverse planting system showed better results in the rooting of the cuttings. As to the plant hormones used, the beta indolacetic acid, at a concentration of 100 mg to the litre of distilled water, contributed to increase the percentage of fixing the roots of the cuttings.
