Evaluación agronómica de cinco especies de plantas ornamentales para uso de jardinería vertical natural de la ciudad de Riobamba.

Abstract

This research aimed to evaluate five species of ornamental plants for use in natural vertical gardening in Riobamba city such as flamingo plant (Hypoestes sanguinolenta), false heather (Cuphea hyssopifolia), Duranta repens (Duranta repens Linn), ribbonplant (Chlorophytum comosum) and bloodleaf (Iresine herbstii). The research work was carried out in the Faculty of Natural Resources at Escuela Superior Politécnica de Chimborazo in an area of 11,76 m2 with five treatments, 27 plants per each one, and three repetitions. The variables and indicators were Acclimatization at 15 and 30 days after treatment, vigor every 15 days, plant height every 15 days after treatment. These indicators were carried out considering 10 plants of each species at random, while for the dry matter three plants were sacrificed per treatment and for the economic analysis the variable costs and fixed costs were considered. For acclimatization the species Chlorophytum comosum presented a value of 90%, for vigor it presented a median of 1,2, so it was the best, in the height variable the species Hypoestes sanguinolenta obtained an average growth of 1,63 cm and the implementation for the vertical garden was $2308,16. Therefore, the best species to be implemented in the natural vertical garden were Hypoestes sanguinolenta, Duranta repens Linn, Iresine herbstii and Chlorophytum comosum adapting to low temperatures. It is recommended to use other species belonging to the Lythraceae family.
