13. Biologia reprodutiva de três espécies distílicas de Psychotria L. e efeitos da fragmentação florestal no sucesso reprodutivo e na diversidade genética de P. hastisepala Müll. Arg. (Rubiaceae) / Reproductive biology of three distylous species of Psychotria and effects of forest fragmentation in the reproductive success and the genetic structure on P. hastisepala Müll. Arg. (Rubiaceae)
The aims were to analyze the aspects of reproductive biology, including the reproductive success, of three Psychotria distylous species, P. conjugens, P. hastisepala and P. sessilis, in 2004/2005 and 2005/2006, in the largest forest fragment in the municipality of Viçosa (2045S and 42 54W), in the state of Minas Gerais, southeastern Brazil. Besides that, it

14. ProduÃÃo de crisÃntemo cultivado em diferentes substratos fertirrigados com fÃsforo, potÃssio e silÃcio / Production of chrysanthemums grown in different substrates fertirrigated with phosphorous, potassium and silicon.
The effect of different substrates and concentrations of phosphorous, potassium and silicon in solutions of fertirrigation (SF) were evaluated during the development of chrysanthemums (Dendranthema grandiflorum) cv. âPuritanâ. After 90 days of rooting, the number of inflorescences, leaves, stems per plant and vase, inflorescences diameter and plant height

16. CaracerÃsticas morfo-agronÃmicas e deterioraÃÃo controlada em sementes de tagetes / Morpho-agronomic characteristics and controlled deterioration in Tagetes seeds
The species of the genus Tagetes, commonly known by Marigold, present easy cultivation, are quite ornamental and show a relatively long flowering cycle. T. patula L. cultivars present a full blooming during the summer and can be traded either as cut flowers or as potted plants. On despite of its economic importance, little is known about their morpho-agronom

17. Características agronômicas e genéticas de Helicônias na Zona da Mata de Pernambuco. / Agronomic and genetics traits from Heliconia genotypes in the Pernambuco Forest Zone.
The genotypes of the Heliconia Germoplasm Collection of University Federal Rural of Pernambuco (UFRPE), implanted in December of 2003 in Camaragibe, were valued agronomic traits. In the first stage, information on number of shoots per clump (NPT) and the clump basal area (AOT) of 26 Heliconia spp. genotypes, cultivated at full sun and partial shade, accordin
