13. Citogenética em espécies de cestrum (Solanaceae) : mapeamento físico e proteínas cromossômicas
Os representantes do gênero Cestrum são, em sua maioria, arbustos e pequenas árvores distribuídos nas regiões tropical e subtropical das Américas. Nesse trabalho, estudamos três espécies coletadas no Brasil (C. capsulare, C. corymbosum e C. megalophylum) e uma na Argentina (C. laevigatum) utilizando as seguintes ferramentas citogenéticas: i) colora�

14. Filogeografia, diferenciação geográfica e caracterização citogenética de populações naturais de Psychotria ipecacuanha das florestas Atlântica e Amazônica / Phylogeography, geographic differentiation and cytogenetic characterization of natural populations of Psychotria ipecacuanha from the Atlantic and Amazon forests
Ipecac (Psychotria ipecacuanha) is a small perennial shrub, which grew abundantly under shady areas of tropical rain forests of Brazil. The species was employed by native Brazilians who taught the medicinal properties to European settlers. Ipecac roots have achieved worldwide usefulness as an expectorant, amoebicide, and vomitive agent because of its pharmac

15. Morfologia floral, citometria de fluxo e citogenética em Lycopersicon esculentum Mill. acesso BGH 160 / Floral morphology, flow cytometry and cytogenetic in Lycopersicon esculentum Mill. access BGH 160
Tomato (Lycopersicon esculentum Mill.) is the second most cultivated vegetable in the world. In Latin America the largest producer is Brazil, with a total area of 58,5 thousand hectares and production of 3,3 thousand tons. Part of the increase in production has been attributed to investments in breeding programs and to innovations generated by biotechnical p

19. Estudo citogenético em representantes do gênero Eleocharis (cyperaceae)
O gênero Eleocharis (Cyperaceae) apresenta cerca de 600 espécies distribuídas desde os trópicos até os pólos porém, ocupa preferencialmente a área tropical das Américas. Eleocharis é reconhecido em Cyperaceae pela inflorescência única sem brácteas involucrais. As características citológicas como, cromossomos holocêntricos, meiose pós-reducio

20. MicropropagaÃÃo e duplicaÃÃo cromossÃmica de hÃbridos triplÃides de capim-elefante e milheto / MicropropagaÃÃo e DuplicaÃÃo CromossÃmica de HÃbridos TriplÃides de Capim-elefante &Milheto.
Interspecific triploid (3x) hybrids, obtained through the combination of elefant-grass (2n = 4x = 28) with pearl milet (2n = 2x = 14) can overcome their ancestors in production and forage quality. Therefore, they are an alternative to obtain superior cultivars, contributing to increase the production and profit in milk production. However, the greatest limit
