Alternatives for the enraizamiento of stakes of Ixora coccinea L. var. coccinea

The work was developed in the Ornamental Plant Nursery Community Services in Cienfuegos. To contribute to the rooting of cuttings, two experiments, one in a moist chamber and the other in natural conditions. In the first trial were evaluated 20 variants in a three-factor completely randomized design. The factors were the stakes of the sections of the branches (apical and subapical), made of Trichoderma harzianum strain A-34 (solid and liquid) at doses (0, 30, 125, 250 and 500 g / L or mL / L). The experimental unit was each stake, evaluating 40 per variant, in the second trial evaluated the best variants of the first. In moist chamber conditions achieved a 100% survival and a level of 92.5% rooting for cuttings apical and 40% for subapical. Application of Trichoderma, in both formulations, a dose of 500 g / L or mL / L, increased rooting in subapicals a greater number, length and thickness of roots, both of apical and subapical. The highest percentage of plants grown in bags was obtained with apical and subapical cuttings treated with Trichoderma solid and liquid at 500 g / L or 500 mL / L.
