Enraizamiento “in vitro" y posterior aclimatación del cultivar de caña de azúcar C95-414 con el bioestimulante cubano Fitomas–E.

The effect of three doses of Fitomas–E (0.5, 1.0 and 1.5 ml. L-1 of culture medium) in comparison with the Indole Acetic Acid (IAA) on the rooting and later acclimatization of sugarcane cultivar C95-414 was studied. The evaluated variables were Percentage of rooted plants, number of roots, longitude of the stalk, the root and the leaf +1, number of active leaves and fresh and dry mass of the plant. In the acclimatization stage, the formation of the root ball was also assessed. The results in the rooting stage showed that the treatments with Fitomas–E were always, from the statistical point of view, in the first place in the percentage of rooted plants, longitude of the plant and of the leaf +1, being the best dose 1.0 ml of Fitomas–E per liter of culture medium. The rest of the variables did not show statistical differences among treatments. In the acclimatization stage, the plants that were treated with Fitomas-E did not show statistical differences among the doses of the bioestimulating applied in none of the evaluated parameters, but they did showed statistically positive results when comparing with the standard. These results suggest the convenience of substituting the IAA by Fitomas– E in the rooting stage of sugarcane cultivars as an alternative in the substitution of imports, when added at the culture medium at a rate of 1.0 ml. L-1 of the bioestimulating. [ABSTRACT FROM AUTHOR]
