Temperatura base, filocrono y eficiencia de uso de radiación de cultivares de okra

ABSTRACT This study aimed to determine the base temperature, phyllochron, solar radiation use efficiency, and productivity of okra cultivars in five sowing seasons at a latitude near 30° S. The experiment was carried out in the experimental area of the Department of Plant Production of the Federal U...

Moench Santa Cruz 47 Valença Phenology ABSTRACT This study aimed to determine the base temperature, phyllochron, solar radiation use efficiency, and productivity of okra cultivars in five sowing seasons at a latitude near 30° S. The experiment was carried out in the experimental area of the Department of Plant Production of the Federal University of Santa Maria during the agricultural season of 2016/2017. Treatments were composed by ten combinations of two okra cultivars (Santa Cruz 47 and Valença) and five sowing seasons (season 1 = 11/4/2016, season 2 = 11/19/2016, season 3 = 12/4/2016, season 4 = 12/19/2016, and season 5 = 1/3/2017). The experimental design was a randomized block design in a 5 × 2 factorial scheme, with a split-plot arrangement and four replications. The five sowing seasons were randomized in the main plot and the two cultivars in the subplot. Spacing was 0.8 m between rows and 0.40 m between plants in the row. Base temperature, which was estimated using the lower mean-square error (MSE), presented values of 11.5 and 11.0 °C for the cultivars Santa Cruz 47 and Valença, respectively. Phyllochron ranged between sowing seasons from 14.4 to 18.9 °C day leaf−1 for the cultivar Santa Cruz 47 and 18.4 to 25.7 °C day leaf−1 for the cultivar Valença. The cultivar Valença presented a higher radiation use efficiency, resulting in a higher fruit productivity.info:eu-repo/semantics/openAccessUniversidad de Tarapacá.
