Fenologia e qualidade de hastes florais de cultivares de gladíolo em Erechim/RS

Abstract

The gladiolus, popularly known as Santa-Rita palm, produces spike-shaped floral stems, with florets of varying colors depending on the cultivar. This study evaluated four Gladiolus cultivars in Erechim/RS regarding phenology and commercial quality of flower stems. The experiment was carried out at the Federal University of the southern border, Erechim campus, with four Gladiolus cultivars: Gold field, White goddess, Priscila and Tradehorn with planting in August 2022. The evaluations carried out were: speed of emergence, number of plants emerged, days after planting of the phenological stages, plant height, characteristics of the floral stems (length, diameter and number of florets) and quality of stems (according to the marketing Veiling standard). The speed of emergence, the days after planting of the vegetative and reproductive stages were similar between cultivars, with a smaller number of plants emerging in Tradehorn. Differences were observed for all characteristics of flower stems. Tradehorn produces longer stems, Gold field has fewer spikes and florets, and White goddess has a smaller diameter. Regarding the quality of stems, only the cultivar Priscila did not have any stems declassified by length and all cultivars meet the standards of thickness and total length/tassel ratio. Therefore, in the cultivation conditions of Erechim/RS, in the year 2022, phenologically the gladiolus cultivars Gold field, White goddess, Priscila and Tradehorn are similar and produce rapid florals that meet commercial quality standards.
