Produção de amarílis em diferentes recipientes e sombreamento nas condições do Semiárido Pernambucano

Abstract

Amaryllis is a bulbous plant commonly sold in pots. Among the flowering plants it has evidence for its umbellated inflorescences consisting of two to twelve flowers positioned on a smooth and hollow green scape with large flowers. However, amaryllis is not cultivated commercially in the Northeast and studies are lacking to guide production, especially for small producers. Thus, the objective of this study was to evaluate the viability of commercial cultivation of amaryllis under Pernambuco semiarid conditions. The experiment was conducted at the Serra Talhada-UAST Academic Unit of the Federal Rural University of Pernambuco-UFRPE between June and August 2019. It consisted of a 4X2 bifactor, in which 4 levels of shading (0, 30, 50 and 70 were tested). %) and two types of recipient(1.10 and 3.6 liters). The vegetative parameters analyzed were: leaf length (cm), number of leaves, number of floral leaves, diameter of the floral leaves (cm), length of the floral leaves (cm) and the reproductive parameters were: days for flower opening, number of leaves. flowers, flower crosssectional diameter (cm) and flower longevity. Data were submitted to the mean and regression test in the R statistical program. The best development of leaf length was in the 70% shading mesh and in the 3,6 liter recipient. The length of the floral scape obtained better results in the 70% shading mesh and there was no difference between the recipient volumes. There was greater uniformity in the number of days in the 70% shading mesh, with floral opening within 32 days. For the diameter of the floral scape, the flower cross-sectional diameter, the number of flowers and the number of leaves there was no statistical difference between the analyzed factors. Therefore, the commercial cultivation of amaryllis bulbs of the Minerva variety is viable in Pernambuco semiarid conditions from June to August in 70% shading mesh and in the types of recipient.
