“…The demand for exotic species, different from those traditionally found on the market, such as the species N. innocentii, has shown a significant and growing market value, and the exploitation of this potential in the international trade can promote the development of these regions, especially the small producers. Anacleto et al (2019) and Tamaki et al (2020) corroborate this statement and add that the most effective way to combat extractivism is the possibility for extractors to adhere to the agronomic cultivation of the species, and they reveal that among the limiting factors of this migration, is the lack of knowledge about which are the more efficient substrates for each species.…”

“…Another determining factor is that, while temperate climate flowers have an average pot life from 5 to 10 days, tropical flowers last from 20 to 30 days (Ferreira and Anacleto, 2019). Among the tropical flowers that have been gaining prominence in the trade, the bromeliads stand out, as they have characteristics favorable to commercialization (Nasser et al, 2019;Dias et al, 2020) such as beauty, exotic flowers and inflorescences (Tamaki et al, 2020), in addition to their intense colors (Anacleto and Negrelle, 2019).…”

GERMINATION AND SURVIVAL OF Nidularium innocentii Lem. (BROMELIACEAE), ORNAMENTAL BROMELIAD ON LOW-COST SUBSTRATES FOR CULTIVATION: AN ALTERNATIVE TO EXTRATIVISM

The extractivism of bromeliads in Paraná for ornamental purposes has been occurring since the 70's, due to the easy access in the forests, the high demand of consumers, and the small number of producers in the region. Among the species of this group stands out Nidularium innocentii Lem. as the second most extracted species with commercial purpose. The reversal of this situation may be associated with the implantation of agronomic crops, but there are few and sparse studies on the germination of this species. Thus, in this context a study was carried out in order to evaluate seed germination and survival on different substrates. Six alternative types of substrates that were easily accessible to the rural producer were tested: peat, coconut husk fiber, plantmax®, earthworm humus, humid pine bark and sieved agricultural soil. The experiment was carried out in a completely randomized design, with four replicates and 25 seeds per experimental unit, at room temperature, in a greenhouse, with sprinkler irrigation for a period of 90 days. Nidularium inocentii showed germination on average at 7 days and maximum germination point was reached at 15.2 days, with an average of 65.8% of germination. Among the substrates tested, coconut husk fiber, peat and humid pine bark obtained the best results on seedling survival after seed germination. The study confirms the feasibility of sexual reproduction of the species for agronomic crops using low cost and locally abundant substrates.

“…Sexual reproduction involves the formation of a seed with a higher count of individuals from a single plant, however, with certain limitations regarding the maturity of seedlings and a long interval until flowering. In that context, basic information about germination is crucial to lead the plant to its full potential (Marialva, Lopes, Valente, & Chagas, 2019;Tamaki, Carvalho, Lazarini, & Nievola, 2020).…”

Bromeliads are used in landscaping due to the beauty of their leaves and flowers. The use of plant regulators such as nitric oxide (NO) promotes the stimulus of germination and it has been a way out to enhance production and reduce the search for plants in nature and nanoencapsulation aims to optimize its effect. The objective of this work was to evaluate the effect of using free and nanoencapsulated NO donor on the germination of D. excelsa. The treatments consisted of soaking the seeds for 5 minutes with s-nitrosoglutathione (GSNO), chitosan/sodium tripolyphosphate nanoparticles containing GSNO (NP CS/TPP-GSNO) and empty (NP CS/TPP) at doses: 15 mM and 20 mM. The control consisted of imbibition in distilled water. For each treatment, 4 replications of 50 seeds were used. The following variables were evaluated: percentage of germination (GER), first germination count (FGC), germination speed index (GSI), mean germination time (t) in addition to the length (SL) and seedling dry weight (SDW). To characterize the seeds, water content and viability were evaluated. D. excelsa seeds had 9.9% water content and 64% viability. For GER, treatments with GSNO ranged from 43 to 60%. The application of GSNO stimulated the germination process of D. excelsa and the nanoencapsulation did not cause any difference in the results compared to the free GSNO. It was concluded that the application

O objetivo deste estudo foi investigar a ação da luz e de tratamentos térmicos pré-germinativos na embebição de sementes de Alcantarea imperialis. As sementes foram dispostas em unidades experimentais de 25 sementes sem desinfestação prévia e submetidas a altas e baixas temperaturas e à ausência e presença de luz. Os resultados mostraram a germinação das sementes de A. imperialis somente na presença de luz, apresentando diferenças na absorção de água entre os tratamentos térmicos ao longo do tempo e confirmando o comportamento trifásico de embebição. Apesar das diferenças encontradas entre os tratamentos, a germinação foi baixa, sugerindo que o processo possa ter sido influenciado pela viabilidade das sementes e por processos hídricos puramente físicos. Nesse sentido, ressalta-se a importância de procedimentos de desinfestação e testes de vigor, bem como a necessidade de estudos futuros das relações hídricas das sementes dessa espécie.
