Abstract: aiming to contribute to the better understanding of the wild harvesting participation in the context of the bromeliads trade, the results from a study focused on: a) identifying and to characterizing the bromeliads wild harvesters (formally and not formally registered) in the state of the paraná; b) identifying and characterizing the harvesting methodologies, preparation and trade routes, and c) surveying the harvesters opinion on the facilities and difficulties of bromeliads wild harvesting are presented. the bromeliads wild harvesting was detected in 12 municipalities at parana state, involving 31 harvester families, most of them concentrated at the coastal zone (n=10) and ortigueira mun. (7). two basic harvester types were identified: resident and opportunist with outstanding differences between them especially related to volume and forms of extraction. a total of 21 bromeliads species were identified as submitted to wild harvesting, being the more frequently collected: vriesea incurvata gaudich. (cited by 90% of the interviewed harvesters), nidularium innocentii lem. (77%), vriesea platynema gaudich. (67%), tillandsia stricta sol. ex ker gawl. (55%) and vriesea carinata wawra (55%).

Revista Ceres , 2013,
Abstract: Realizou-se um estudo prospectivo da cadeia produtiva de bromélias no Estado do Paraná, objetivando conhecer o perfil do produtor paranaense, com respectiva capacidade de atender às demandas de mercado, identificar e caracterizar os diferentes níveis da cadeia produtiva e detectar os principais pontos de estrangulamento do desenvolvimento desse setor. Para tanto, foram entrevistados 19 produtores, 160 varejistas e 18 atacadistas. A quantidade de bromélias oriundas da produ o do Paraná e aptas ao mercado era de 5.340 plantas ao ano, inferior à demanda do Estado. As condi es exigidas pelos varejistas (v) e atacadistas (a) para aquisi o de bromélias dos produtores regionais eram: pre o igual ou inferior ao praticado em S o Paulo (exigido por: v = 134; a = 18), qualidade da produ o condizente com a encontrada no mercado (v = 86; a = 16), capacidade de efetuar entregas periódicas (v = 81; a = 11) e capacidade de atendimento dos pedidos extras (v = 55; a = 7). N o foi encontrado produtor no Estado do Paraná que pudesse atender a todas as exigências de forma simultanea. Os principais entraves que impediam a inser o da produ o no mercado regional eram decorrentes da inaplicabilidade dos modelos de gest o da produ o rural, adotados pelos produtores, e das incongruências tecnológicas observadas na maioria dos viveiros de cultivo, que resultavam em produ o de baixa qualidade. This paper is a prospective study about the bromeliads production and trade in Paraná State, Brazil, which aimed to know the producers' profile in Paraná State with the respective capacity of meeting market demands, identify and characterize the different levels of the bromeliads production chain, as well as detect the main bottlenecks to the development of this sector. A total of 19 producers were interviewed; 160 retailers and 18 wholesalers. The amount of bromeliads from the regional production and suitable to be the traded was 5340 plants per year, which was lower than the State demand. The conditions demanded by retailers (r) and wholesalers (w) to purchase bromeliads from regional producers were: equal to or lower price than it is sold in S o Paulo (required by: r = 134; w = 18), production quality demanded as found in the market (r = 86; w = 16), ability to make regular deliveries (r = 81; w = 11) and replacement capacity for requests of extra orders (r = 55; w = 7). It was not found in Paraná a producer that could meet all requirements simultaneously. The main barriers that prevented the inclusion of production in the regional market were due to the inapplicability of the rura

Abstract: Este trabalho apresenta resultados de monitoramento fenológico equantifica o da produ o de sementes de Vriesea incurvata Gaudich, realizados no Parque Estadual Rio da On a (município de Matinhos, Estado do Paraná, 25o 50’S e 48o 30’ W). Registrou-se a ocorrência das fenofases de flora o, frutifica o, dispers o e emiss o debrotos laterais. Paralelamente, coletaram-se 30 inflorescências em duas oportunidades (agosto de 2003 e 2004), sendo estas avaliadas quanto ao tamanho, número de frutos formados e quantidade de sementes. O início de flora o foi evidenciado a partir de janeiroe fevereiro, com pico em abril e maio. A frutifica o e a emiss o de brotos clonais iniciaramse em abril com pico em junho e julho e a dispers o teve início em agosto seguindo até dezembro. Houve correla o positiva entre a fenofase de emiss o de inflorescência paratemperatura e o fotoperíodo. A frutifica o e a emiss o clonal apresentaram correla o negativa com o fotoperíodo durante o monitoramento. The results of phenological monitoring and quantification of seedproduction of Vriesa incurvata Gaudich were presented. The study was carried out in Rio da On a State Park, (Matinhos, Paraná State, Brazil, 25 ° 50′S and 48° 30′W). The occurrence of flowering, fructification and dispersion phases, and sprouts were registered. In parallel, 30 inflorescences were collected in two dates (August, 2003 and 2004) in order to evaluated the size, number of developed fruits and amount of seeds. The flowering happened from January to February, with the highest level observed in April and May. Fructification andthe emission of clone sprouts began in April and persisted through June and July. Dispersal started on August and continued until December. There were positive correlations between the phenophases of inflorescence emission to temperature and photoperiod. The fructification and emission of clone sprouts presented negative correlation with photoperiod during monitoring.

Abstract: Avaliou-se a germina o das sementes de Aechmea nudicaulis (L.) Griseb. (Bromeliaceae). As tentativas de produ o desta espécie, a partir de sementes, têm ocorrido de forma empírica, utilizando-se substrato à base de pó de xaxim (Dicksonia sellowiana Hook.), que tem restri es de uso, por estar amea ada de extin o. Foram testados cinco tipos alternativos de substratos de fácil acessibilidade: húmus de minhoca, areia, fibra de casca de coco, serapilheira e Plantmax . O experimento foi realizado em delineamento inteiramente casualizado, com quatro repeti es e 50 sementes por unidade experimental, àtemperatura ambiente, em viveiro rústico, coberto com sombrite (70%). Leituras semanais foram efetuadas, durante 70 dias. A melhor performance, como substituto alternativo, foi a da serapilheira, que apresentou valores de germina o de 79,5% e sobrevivência de 97%,estatisticamente similares aos obtidos com xaxim (78%; 94,75%; Tukey, p < 0,05). Adicionalmente, este produto apresenta como características positivas, alta disponibilidade, baixo custo e fácil reciclagem. For this study, the germination of Aechmea nudicaulis (L.) Griseb. (Bromeliaceae) was evaluated. Production attempts from seeds for this species have taken place in an empirical form, using substratebased on xaxim (Dicksonia sellowiana Hook.) powder, the use of which is currently restricted, as it is an endangered species. Five easily accessible alternative substratum were tested: worm humus, sand, coconut shell fiber, forest litter, and Plantmax . The experiment wasconducted using a completely randomized design, with four replications and 50 seeds per experimental unit, at room temperature in a rustic nursery covered with 70% shade cloth. Weekly readings were performed during 70 days. The best alternative as a substitute toxaxim was forest litter, due to its germinability of 79.5% and survival rates of 97%, significantly similar to xaxim (78%; 94.75%; Tukey p < 0,05). Additionally, this product features positive characteristics such as high availability, low cost, and easy recycling.
