Growth, development and quality of gladiolus ‘White Goddess’: season, shade net, and mulching

ABSTRACT To reduce the risks associated with production of gladiolus flowers in climatic conditions southwestern Paraná, Brazil, this study characterized growth, development, and floral stem quality plants cultivated under different-colored shade nets mulching four growing seasons. The cultivar ‘White Goddess’ was grown beds without soil. Three individually stained black, silver red all 35% shading, were used study, an additional treatment (control) which full sun. Growth (LAI height), development (cycle days, degree-days), flower (size damage) evaluated eight each treatment. Plants distributed a randomized block design factorial scheme (season x screen). cycle ranged from 66 to 89 days 1732 1268°C day. mean difference between treatments 3 days. Less damage happened net more shading favored growth characteristics plants, autumn, had highest standard.
