“…Foram identificados, por meio do processo de amostragem autogerada (Malhotra, 2006;Negrelle & Anacleto, 2012), 27 atacadistas atuando no Paraná. A totalidade foi contatada para agendamento das entrevistas, porém, apenas 18 gerentes ou proprietários, em oito municípios, se predispuseram a responder às entrevistas.…”

“…Em 2004, era o terceiro maior produtor no Brasil, com 250 mil plantas ao ano, que eram produzidas por 144 produtores, em 32 municípios (Ibraflor, 1999;Anacleto et al, 2008;Negrelle & Anacleto, 2012). Entretanto, na última década houve significativa redução do número desses produtores, assim como da produção (Anacleto & Negrelle, 2009;Negrelle & Anacleto, 2012).…”

Bromeliads production and trade in Paraná, BrazilThis 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 São 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 rural production management models adopted by the producers and the technological inconsistencies observed in most of the culture hatcheries that resulted in low quality production.

“…However, easy access to the environments where naturally bromeliads grow, high density of this resource in these places, associated to lack of financial resources, land distribution problems, lack of technical and agricultural support and environmental limitation are factors that discourage the implementation of cultivation systems and reinforce the extractive standard (Negrelle & Anacleto, 2012).…”

In vitro germination and growth of Vriesea incurvata Gaudich. (Bromeliaceae)

2018

Vriesea incurvata in the natural environment shows some difficulties associated to the low seed germination capacity. Aiming to provide basis for the seedlings production, the results of the seeds germination percentage and the initial growth of V. incurvata seedlings in vitro conditions in different culture media, are reported. Completely randomized design was comprised of eight treatments and eight replications. The treatments were as culture media: MS (Murashige & Skoog); MS½; KC (Knudson); KC½; MS + activated carbon (AC); MS½ + AC; KC + AC; and KC½ + AC. The germination percentage was calculated from the division between the number of seeds with primary root extrusion by the total number of sowed seeds. The initial growth was evaluated considering the values of total fresh biomass, percentage of normal and dead seedlings, number and roots length, stem length, number of leaves and percentage of chlorotic, necrotic and dead leaves, respectively. All the cultures promoted high germination percentages (> 82.8%). In MS and MS½ medium, it was evidenced the highest percentage of normal seedlings, the highest values of fresh biomass production, stem growth and number of leaves. KC and KC½ medium also promoted highest percentages of normal seedlings and low percentages of necrotic and dead leaves. The addition of activated carbon in the culture media was unfavorable to promote the growth of seedlings. This suggests that MS and MS½ are the most suitable culture media for the production of Vriesea incurvata in vitro.

The present study aimed to evaluate the effect of different concentrations of calcium on growth and development of silver vase bromeliad (Aechmea fasciata). Plants were fertilized three times a week with nutrient solutions formulated with HA solution (Hoagland and Arnon, 1950) modified with 0.25, 2.5, 5, 7.5, 10.0 or 12.5 mM Ca applied into the tank. After 90 days of experimentation, biometric and biomass measurements of root and shoot systems, and chemical analysis of leaves were assessed. The results showed that the concentration of 12.5 mM Ca in nutrient solution is recommended for silver vase bromeliad fertilization.
