GONZALEZ VEGA, María E et al. Effect of Bioenraiz^® as stimulant of coffee plants (Coffea arabica L.) germination and the development. cultrop [online]. 2015, vol.36, n.1, pp. 73-79. ISSN 1819-4087.

Biotechnological methods for obtaining of efficient products, from bacterias with beneficent properties, represent an alternative of interest for the development of economical important crops in the context of a sustainable agriculture. The effect of Bioenraiz^® in germination and plants growth during the process of plants coffee obtaining of “Caturra rojo” (Coffea arabica L.) was studied. Three concentrations of the biopreparation: 200, 220 and 230 mL L^-1 and a Control were evaluated. The application was carried out before the inoculation of the seeds through the imbibitions for 20 min and when the first pair of leaves was reached. The germination was evaluated 50 and 60 days after the inoculation. The height, diameter of shaft, pair of leaves and dry mass were evaluated to the seven months. Differences in the answer to the germination for both periods were evidenced, the best treatment was that of 200 mL L^-1 of Bioenraiz^®, where 79,4 and 94,5 %, respectively were obtained. Seeds treated with the biopreparation originated plants that showed significant differences with the control for the evaluated variables, effect that is attributed to the chemical composition of the biopreparation that is characterized by not causing adverse alterations in the ecological environment. The results contributed from the economic point of view, to the recovery of coffee in Cuba, achieving plantation material with natural products and the required quality
