Abstract
- Cultivation conditions are determining factors that affect the quality of cut flowers. The objective of this study was to evaluate the vegetative growth, flowering and vase life of commercial gladiolus cultivars under different shading conditions in the Brazilian semi-arid region. Two cultivars of gladiolus (Jester and Rose Friendship) were grown under two conditions: full sun and 70% shade. Biometrics were evaluated 60 days after planting and the growth rate of the crop was evaluated at 15-30, 30-45 and 45-60 days for the variables: number of tillers, stem diameter, number of leaves and plant height. After 45 days, the fresh weight, dry weight and total relative water content of the area and root parts of the plants were evaluated. After the harvest, the stems were kept at a temperature of 22±3 °C and relative humidity (RH) of 60%. Visual assessment, pH of the solution, variation in the volume of water and loss of fresh mass were measured every two days. Cultivation with 70% shading resulted in greater accumulation of biomass in the aerial part of gladiolus plants, greater neck diameter and height. The Rose Friendship cultivar underwent a greater translocation of dry matter to the aerial part of the plants, resulting in greater height. On the other hand, the gladiolus stems from cultivation under full sun conditions resulted in longer vase life, 10 days under conservation conditions at 22±3 °C and RH 60%. Resumo As condições de cultivo são fatores determinantes que afetam a qualidade das flores de corte. Diante disso, objetivou-se, neste estudo, avaliar o crescimento vegetativo, floração e vida de vaso de variedades de gladíolos comerciais no semiárido brasileiro, sob diferentes condições de sombreamento. Duas variedades de gladíolos (Jester e Rose Friendship) foram cultivadas em duas condições: sol pleno e 70% de sombreamento. Avaliou-se a biometria em 60 dias após o plantio e a taxa de crescimento da cultura aos 15-30, 30-45 e 45-60 dias para as variáveis: número de perfilhos, diâmetro do colo, número de folhas e altura da planta. Após 45 dias, avaliou-se a massa fresca, massa seca e conteúdo relativo de água total da parte área e da parte radicular das plantas. Após a colheita, as hastes foram mantidas em temperatura de 22±3 °C e umidade relativa (UR) de 60%. A cada dois dias, realizou-se avaliação visual, além de avaliação do pH da solução, variação no volume de água e perda de massa fresca. O cultivo com 70% de sombreamento resultou em maior acúmulo de biomassa na parte aérea das plantas de gladíolos, maior diâmetro do colo e altura. A variedade Rose Friendship resultou em maior translocação de massa seca para a parte aérea das plantas. Isso resultou em maior altura. Por outro lado, as hastes de gladíolos provenientes do cultivo nas condições de pleno sol resultaram em maior vida de vaso: 10 dias em condições de conservação a 22±3 °C e UR 60%.
