“…They may be involved in both chemical and mechanical defense, negatively affecting the oviposition rate and feeding of herbivorous insects and nutrition of larvae (Lokesh and Singh 2005). It is possible that the leaf trichome density in the studied species can play a role in protection against herbivores insects, which are considered pests in the cultivation of some species of this genus, such as beetle (Barbosa and Fonseca 2002), caterpillar (Lourido et al 2007), and leaf-cutting ants (Delabie 1989). However, additional studies are needed to better understand the ecological role of these trichomes in Theobroma.…”

Theobroma species have economic importance due to their use in the cosmetic and food industries, mainly in the production of chocolate. However, the anatomy of their vegetative structures remains poorly studied. The goal of this study was to describe the anatomical features of Theobroma grandiflorum, T. speciosum and T. subincanum to contribute to the biological knowledge of these species, as well as provide support to the biotechnological studies of native fruit plants of the Amazon. Leaves at different developmental stages were collected and analyzed under light microscopy and scanning electron microscopy. Sessile and stalked stellate trichomes and digitiform glandular trichomes were observed in the expanded leaves of T. grandiflorum and T. subincanum. These species were also similar in the morphology of the midrib, the organization of the mesophyll and the presence of starch grains in the midrib pith cells. Claviform glandular trichomes and mucilage cells in the epidermis occurred only in the expanded leaves of T. speciosum. The presence of mucilage secretory trichomes in shoot apices (colleters) of all species is a new finding for the genus Theobroma. KEYWORDS: colleters, cupuassu, glandular trichomes, mucilage, stellate trichomes. Caracteres anatômicos foliares de três espécies de Theobroma (Malvaceae s.l.) nativas da Amazônia Brasileira RESUMOAs espécies de Theobroma têm importância econômica devido a sua utilização nas indústrias cosmética e alimentícia, principalmente na produção de chocolate. Entretanto, a anatomia de suas estruturas vegetativas permanece pouco conhecida. O presente estudo teve por objetivo descrever as características anatômicas de Theobroma grandiflorum, T. speciosum e T. subincanum, como contribuição ao conhecimento biológico dessas espécies, bem como, fornecer subsídios aos estudos biotecnológicos de fruteiras nativas da Amazônia. Folhas em diferentes estágios de desenvolvimento foram coletadas e analisadas sob microscopia de luz e eletrônica de varredura. Nas folhas expandidas de T. grandiflorum e T. subincanum foram observados tricomas dos tipos estrelado séssil, pedunculado e glandular digitiforme. Estas espécies também foram similares quanto à morfologia da nervura central, à organização do mesofilo e à presença de grãos de amido no parênquima medular da nervura central. Tricomas glandulares claviformes e células mucilaginosas na epiderme do limbo foliar ocorreram somente em T. speciosum. A presença de tricomas secretores de mucilagem nos ápices vegetativos (coléteres) de todas as espécies estudadas é um novo registro para o gênero Theobroma.

Work relations and helping in the lives of Amazon rural women workers

2017

Changes in methods of agricultural production have impacted on the lives of those involved in this sector. New social relations, technologies, values and landscapes have been introduced as well as potential risks to health. Female workers have a specific experience that requires a closer analysis to understand their situation. The research addresses the interrelationship of health, work, and the environment of women agriculturalists in a rural Amazonian community. This focus allows the identification and understanding of relations between the women and the actors with whom they share daily activities and the implications for health, work, and self-image. Using qualitative methods the experiences of 47 women were captured through collective interviews, which were analysed by Nucleus of Meaning Analysis (NMA), adapted from Categorical Content Analysis. Work is central to the lives of the women workers but is attributed with different meanings depending on the context and the relationship. It was found that the relationship with employers increases the risk of workplace exploitation; with male partners work is characterised as 'helping'. Work with female co-workers increases a sense of identity, strengthens social bonds and an ability to solve problems. In conclusion, in addition to issues related to production methods, the subjective relational universe of these workers is marked by a complexity that impacts on their lives and health. The authors suggest that research on the impact of daily life and workplace on health considers the different and complex relations and subjective demands, especially in contexts endowed with uniqueness.
