“…In this context, the species Costus lasius Loes, belonging to the Costaceae family, stands out and, despite having great potential for production and markets in Brazil, it is still a little studied species. This tropical plant, which serves to a restricted ornamentation market within floriculture, occurs naturally in Panama, Colombia, Peru and in Brazil, covering the Amazon region (Gonçalves et al, 2005). Although previously treated as medicinal, because of its beauty and exoticness, it has come to play prominent and innovative role in the Brazilian market.…”

The practice of using different photo-selective nets, associated with the technique of fertigation, represents a new agrotechnological concept that aims to promote specific physiological responses for growth and production, which are regulated by light. The aims of the study were to evaluate the effect of photo-selective nets and potassium concentrations in the fertigation solution on the horticultural performance of Costus lasius. The study was conducted at the Universidade de São Paulo, ESALQ, Piracicaba, SP, Brazil. Three experiments were carried out separately to evaluate five potassium concentrations in the fertigation solution (40, 80, 120, 160 and 200 mg L-1) under three colours of photo-selective nets (red, blue and black) in a randomized block design, with five repetitions. The variables plant height and numbers of leaves, stems and flower buds were evaluated. The data were submitted to the joint analysis of experiments. The association between the K+ concentration of 200 mg L-1 and the black photo-selective net results in higher stem and inflorescence production.

“…However, there are limitations to the expansion of new products, among them the lack of information about intensive cultivation conditions of these potential species and their conservation in tropical conditions. The species of the genus Costus (Costaceae) have great interest because of its beautiful and exotic ornamental inflorescences and foliage (GONÇALVES et al, 2005). Costus are indicated species for landscape design, pot plants, big pot plants and as cut flower and stems (CASTRO et al, 2011).…”

Costus arabicus L. (Costaceae) is a tropical species native from Brazil. The species has ornamental potential as garden and vase plant, and for flower and stem cutting. The aim of this study was to evaluate the seed germination of C. arabicus under different of light and temperature conditions. Seeds subjected to constant temperatures of 20, 25 and 30 °C under photoperiod of 12 h of light or dark. The parameters analyzed were percentage of germination and germination speed index (GSI). The highest germination percentage (70%) was under temperature of 30 °C, both in light or dark. The GSI showed that the germination rate increases as temperature increases, mainly on 30 °C. C. arabicus seeds germinated in the presence or absence of light, thus was considered neutral photoblastic and germination on light under 30 °C was more efficient for seed germination. RESUMOCostus arabicus L. (Costaceae) é uma espécie tropical nativa do Brasil, com potencial como planta de jardim, vaso, flor e haste de corte. O objetivo do trabalho foi avaliar o processo germinativo de sementes de C. arabicus sob diferentes condições de luz e temperatura. As sementes submetidas às temperaturas constantes de 20, 25 e 30 °C, sob fotoperíodos de 12 horas de luz branca e escuro contínuo. Os parâmetros analisados foram a porcentagem de germinação e o índice de velocidade de germinação. A maior porcentagem de germinação (70%) ocorreu sob a temperatura de 30 °C, tanto no claro como no escuro. Os resultados de IVG mostraram que a velocidade de germinação aumenta com o aumento da temperatura, principalmente a 30 °C. As sementes de Costus arabicus germinaram na presença ou ausência de luz, podendo ser consideradas fotoblásticas neutras, sendo a germinação no claro a 30 °C mais eficiente. Palavras-chave: Costaceae, fotoperíodo, índice de velocidade de germinação, fotoblastismo.(1)
