Temporal stability of Heliconia spp. flower stem production

Abstract

The instability of heliconia flower stem production may be related to climatic variation. Therefore, that information is very important for planning the species production throughout Brazil, mainly in northeast region. The objective of this work was analyzed the previous effects of photoperiod, air temperature and precipitation in the flower stem production of Heliconia psittacorum cv. Red Opal, H. psittacorum x H. spathocircinata cv. Golden Torch, H. stricta cv. Fire Bird and H. rauliniana, and the monthly temporal stability. The flower stems with two to three open bracts were harvested twice a week between May, 2004 and March, 2012 from a field in Camaragibe – PE, Rain Forest Zone of Pernambuco, Brazil. Pearson’s linear correlation demonstrate flower stem production occur in response to the environment stimulus. H. rauliniana inflorescence initiation response mainly to the shortest photoperiod and cv. Fire Bird to highest photoperiod. Production of the cv. Golden Torch was more stable in April, with reduction in September (39.46%) and an increase in December (87.02%), compared with the annual average. The cv. Red Opal produced more in September (31.43%), with a reduction in February (44.8%) and stable in July. H. rauliniana production was stable in September and increase in November (274.8%). The cv. Fire Bird production was stable in April, with the lowest production in November and the highest in March (65%). With this information is possible to predict the cultivar production in the Rain Forest Zone of Pernambuco State, Brazil

Global vision of heliconias research as cut flower: a review

“…For topical conditions, the importance of the percentages of shade for the cultivation of heliconias is highlighted because it develops better in these conditions which influences the content of photosynthesized pigments and the growth (Gomes et al, 2016;Souza et al, 2016). E.g.…”

Morphological and molecular characterization of native Heliconia sp. accessions of the Amazon region

“…and H. psittacorum L.f. are adapted to the edaphoclimatic conditions found in the mid-west of Brazil and are widely distributed throughout the national territory. The characteristics of these species are considered adequate to serve the ornamental flower market: high productivity, color variety, and light stems (Gomes et al, 2016;Silva et al, 2017). The ornamental importance of heliconias is mainly related to their exotic colors and shapes, postharvest stem durability, and resistance to transport.…”
