13. Rupture of glandular trichomes in Ocimum gratissimum leaves influences the content of essential oil during the drying method
Medicinal and aromatic plants are commonly sold dried; however, it is necessary to understand the effects different drying methods have on these materials, to ensure their efficiency and quality. Ocimum gratissimum L., Lamiaceae, is an aromatic plant whose essential oil is stored in glandular trichomes. This study aimed to confirm the effects of different dr

14. Biological aspects of the beetle Delphastus davidsoni fed with whitefly eggs laid on tomato genotypes
Many plant breeding programs have incorporated plant resistance characteristics without considering how this resistance may affect the natural enemies of plant pests. We evaluated the biological aspects of Delphastus davidsoni (Gordon) fed with Bemisia tabaci B biotype eggs laid on tomato genotypes with different trichome densities and types. On LA1335 and N

15. Interspecific xenia and metaxenia in seeds and fruits of tomato
Xenia, the transmission of traits from the pollinizer to the female's tissues, is a phenomenon hitherto unknown in tomatoes. Here, we describe xenia effects on the seeds and fruits of Solanum lycopersicum, the tomato, elicited by S. galapagense. The wild tomatoes, such as S. galapagense, have highly pilose fruit surface and minute seeds, unlike the domestica

16. Morphology and anatomy of Justicia acuminatissima leaves
Justicia acuminatissima (Miq.) Bremek., Acanthaceae, is a subshrub found in northern Brazil, where it is widely used by the population of this region as an anti-inflammatory medicine. Despite this popular use, there is no pharmacognostical data to support the correct identification of this species. We therefore performed a morpho-anatomical, histochemical an

17. Anatomical analysis of peach palm (Bactris gasipaes) leaves cultivated in vitro, ex vitro and in vivo
The present work characterized and compared the anatomical structures of the leaves of Bactris gasipaes (Arecaceae) plants grown under different cultivation conditions (in vitro, ex vitro and in vivo) with the goal of identifying the origins of the difficulties encountered in acclimatizing micro-plants. The Quant program was used to determine leaf tissue thi

18. Resistência de genótipos de tomateiro à Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae) biótipo B. / Resistance in tomato genotypes to Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidade) biotype B.
A mosca-branca Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae) destaca-se como uma das principais pragas do tomateiro no Brasil. A busca por cultivares resistentes, derivadas de tomateiros selvagens surge como oportunidade de redução dos problemas causados por esta praga. Assim, genótipos de tomateiro oriundos do cruzamento entre Solanum lycopersicum L. e

19. Evolução e ecologia de tricomas em Bignonieae (Bignoniaceae): estruturas morfológicas de defesa anti-herbivoria? / Evolution and ecology of trichomes in Bignonieae (Bignoniaceae): morphological structures of anti-herbivory defense?
This thesis focused on the evolutionary-ecology of trichomes in the tribe Bignonieae (Bignoniaceae), and in the potential defensive role of these structures against herbivores. More specifically, we characterized four trichome morphotypes found in vegetative plant parts of representatives of the Bignonieae, as well as studied the macro-evolutionary patterns

20. Aspects of leaf anatomy of Kudzu (Pueraria lobata, Leguminosae-faboideae) related to water and energy balance.
Kudzu is a cover crop that has escaped cultivation in some subtropical and warm temperate regions. Kudzu has previously demonstrated broad intraspecific physiological plasticity while colonizing new environments. The objective of this paper was to investigate characteristics of kudzu leaflet anatomy that might contribute to its successful growth in climatica

21. Influence of trichomes on attractiveness and ovipositional preference of Bemisia tabaci (Genn.) B biotype (Hemiptera: Aleyrodidae) on tomato genotypes
Brazil is one of the world's largest tomato producer, but considerable part of the production is lost due to the attack of Bemisia tabaci (Genn.) B biotype. Resistant germoplasm plants can be an important method for B. tabaci control in integrated pest management approaches. The attractiveness and ovipositional preference of B. tabaci for 17 tomato genotypes

22. Controle hormonal da defesa à herbivoria em tomateiro / Hormonal control of herbivory defense in tomato
Even though the cultivation of tomato has a high economical importance, this culture is classified as being of elevated risk because of it common infestation by pests and diseases. This problem makes this culture greatly dependent of the application of several agrochemicals, which leads to increase in cost of production, environmental damages and also facili

23. Sources of resistance to Bemisia tabaci between the tomato plants accessions Horticultural Germplasm Bank of UFV / Fontes de resistência a Bemisia tabaci entre as sub-amostras de tomateiro do Banco de Germoplasma de Hortaliças da UFV
A mosca-branca Bemisia tabaci (Hemiptera: Aleyrodidae) é uma importante praga de Lycopersicon esculentum. Os danos causados pelos adultos e ninfas consistem na sucção de seiva, injeção de toxinas e transmissão de fitoviroses. O uso de variedades resistentes é uma alternativa no manejo dessa praga. No processo de obtenção dessas variedades é fundame

24. Morfoanatomia de frutos e sementes em Apocynaceae / Morphoanatomy of fruits and seeds in Apoctnaceae
This paper had as objective contribute for the knowledge of Apocynaceae by a morph-anatomic survey data from fruits and seeds from species of the family. On this study, 13 species present in Brazil and distributed in three of the five families currently described, were included. Flowers, fruits and seeds in many development levels were collected, fixed and s
