Capacidad bioenraizante de Trichoderma spp. en rosas (Rosa sp.) de la variedad atomic, Cayambe-Ecuador.

Abstract

In the quest to keep up with national and international flower production and trade, the preference for agrochemicals has been justified by the benefits offered by the "Green Revolution", and whose lack of control in their use is causing resistance to pests, pollution, and diseases in humans, effects that have made the search for more ecological production methodologies indispensable. The purpose of this research was to evaluate 4 doses of Trichoderma spp. plus an unblocking agent that combined provides a rooting action in Rosa plants (Rosa sp. var. Atomic). The length of the stem, button width, and the count of absorbent hairs were evaluated, for which a 3-block field design was applied with the treatments distributed completely at random, inoculating the bio-preparation with a concentration of 1x107 CFU/mL, and Measurements were taken on the 7th, 14th and 21st days of each month for 3 months, and when the absorbent hairs were counted, evaluations were taken during the 3 months every 15 days. It was concluded that the application of treatment four (T4) containing 200 mL of Trichoderma spp. + 200 mL of unblocking agent was better for the parameter of stem length, however statistically significant results were not obtained for the width of the bud since Trichoderma spp. It does not present direct activity that favors this parameter, as well as for the count of absorbent hairs, however, the results were encouraging for future studies.
