Evaluación de la eficiencia del extracto tecnológico microbiano en la producción de tallos florales en el cultivo de rosa (Rosa sp.) variedades G672 y White O`Hara Cayambe – Ecuador

Abstract

In Pichincha-Ecuador, specifically in the Cayambe and Pedro Moncayo cantons, one of the main economic activities is the production of roses, an activity that can be diminished by the presence of blind shoots and can reach 40-50% affectation, for this reason. The present investigation was proposed to evaluate the effect of the application of the microbial technological extract in the reduction of blindness in the cultivation of rose (Rosa sp.) varieties G672 and White O`Hara. 4 applications of the product were made, the first by pricking and then every 21 days, in doses of (0.02cc/l), (0.03cc/l), (0.04cc/l), (0.05cc/l ) and was compared with an absolute control, following the manufacturer's recommendation. A completely randomized design (DCA) was obtained with 5 treatments and 6 repetitions, where the variables blind percentage, days to harvest, stem length, peduncle and button were evaluated. The results showed that the T5 treatment (0.05cc/l) with the highest dose, presented a reduction of 13.89% of blindness for the G672 variety and 19.55% for the White O`hara variety, compared to the witness; for the rest of the variables, there were no statistical differences. Considering that floral induction occurs between the first and second week after the pinch, it is recommended to investigate the effect of the product with weekly applications during the first 21 days, using the best dose from this research and including higher doses
