Desempenho morfoagronômico e fisiológico do rabaneteiro sob influência do som: estudo preliminar

Abstract

Radish is a short-cycle vegetable whose tuberous root has economic importance. For the cultivation of this crop, technologies can be used that can contribute to increased productivity, generating greater economic return. One of the techniques that have been evaluated for some vegetables is the use of sound vibrations, whose results have been favorable for several characteristics. Thus, the objective of this study was to analyze the influence of different types of sound on the morphological and physiological characteristics of radish plants. The research was conducted at the ”Horta didática” of the Federal University of Ceará. A randomized block design with four treatments and four replications was used. The treatments were different types of sound: T1 - control (without sound application); T2 - sound of nature; T3 - sound of water; T4 - sound of noise. All sounds were applied with the same intensity, 70 dB. Leaf number, plant height, diameter and length of tubers, root length, fresh and dry mass of shoots, tubers and roots, leaf area, gas exchange and chlorophylls 'a' and 'b' were evaluated. The results showed that there were no differences between the treatments and the control, neither for the morphoagronomic characteristics nor for the physiological characteristics. It was concluded that, for the conditions of this work, the treatments were not able to generate difference between the morphological and physiological factors of radish plants, being necessary to change some experimental parameters and new evaluations to determine the existence or not of sound interference on the development of radish plants.
