Análise de diferentes tecnologias de iluminação artificial para produção de crisântemos em ambiente protegido.

Abstract

In protecting environment chrysanthemum’s production, the artificial illumination type used to induce the photoperiod, affects the growing and development of plants, as well the electric power consumed in this process of production. The most useful illumination type is by filament. Today, new artificial illumination technologies have been studied to reduce the electric power consumption. This work has been development in a commercial greenhouse with four cultivars. The preliminary results showed that the utilization of discharge lamps does not affect significantly the flower’s development considering the weight and presence of flower bud, indicating a possible reduction on power electricity consumption. It shows the technologies used in all treatments have less potential consumption than the witness.
