“…We found that for all the morphological characteristics evaluated, 'Pink torch' had higher averages than 'Red torch'. The development of torch ginger inflorescences is dependent on the availability of plant photoassimilates [8,17], and we accordingly believe that the superiority of 'Pink torch' may be related to the larger photosynthetic area for production of photoassimilate, given that the plants of this cultivar had a higher number of tillers and larger area of clump occupation.…”

Aims: To characterize the development, yield, and morphological characteristics of the ‘Red torch’ and ‘Pink torch’ cultivars of torch ginger cultivated in the Brazilian Cerrado. Study design: The experiment was performed using two cultivars (‘Red torch’ and ‘Pink torch’) with three replications of three ginger torch clumps per plot. Place and Duration of Study: Germplasm Active Bank of Ornamental Tropical Plants of the State University of Mato Grosso (14°08′38′′S, 57°03′45′′W; altitude of 488 m), Brazil, from August 2015 to July 2018. Methodology: At monthly intervals during the first 10 months after planting, we assessed clump development, based on the measurement of the area occupied by the clump, and number of tillers emerging from the clump. The monthly yield per hectare was estimated from August 2016 to July 2018. During this period, the average number of floral stems produced per clump was determined, and the floral stems were characterized during the second year, for stem length, stem diameter, inflorescence length, inflorescence diameter, and fresh stem mass. Evaluations were based on the measurements obtained from 10 stems per clump. Results: First-year clump expansion rates for 'Red torch' and 'Pink torch' were 4.00 and 7.90 cm2, respectively. 'Pink torch' presented a higher monthly average of tiller emergence than 'Red torch', and consequently higher productivity. The cultivars produced floral stems of commercial standard in the second year of growth, with stem lengths and diameters greater than 60.00 cm and 10.00 mm, respectively. In this study, we found that ‘Red torch’ and ‘Pink torch’ showed high yields and produce inflorescences with characteristics suitable for commercialization. Conclusion: The basis of this study, we can conclude that cultivation of torch ginger in the Brazilian Cerrado would be viable.

The inflorescence of Etlingera elatior forms tubular, true flowers in an acropetal sequence that blooms ostentatiously. The aromatic plant also produces excellent flavour and fragrance afforded by the presence of secretory structures capable of accumulating, storing, and releasing volatile compounds. However, there is a lack of botanical description of the flowering morphology and the type of secretory structures involved in plant-pollinator interactions. This study aims to describe the floral morphology, characterise the diverse micromorphology of the epidermal outgrowths in the true flower, and analyse their histochemical contents by scanning electron and light microscopes. Labellum defines the anthesis stage of the true flower: unveiling by petals at anthesis and furling inwards that closes the top part of the flower at post-anthesis. In addition to the floral advertisement accessory function demonstrated by the labellum, the closure provides additional exaptation of post-pollination protection to the flower. Both glandular trichomes and osmophores are involved in biochemical functions that release heterogeneous substances (mucilage, terpenes, and phenolic compounds) to help secure anthesis. Non-glandular trichomes, on the other hand, are structurally involved in the floral development by providing physical and mechanical protection to the flower by acting as glue to maintain the closed structure of the flower, connecting floral accessories, and forming a formidable barrier surrounding the ovary, the most important reproductive organ of the flower. Findings from the present study demonstrate that the presence of secretory structures coordinated with the flower’s functional traits enhances the pollination mechanism. It is the maiden report for E. elatior on epidermal outgrowths and their participation in floral structure and development besides plant-pollinator interaction.
