13. Exploring the role of auxin in the androgynophore movement in Passiflora
The flowers of the species belonging to the genus Passiflorashow a range of features that are thought to have arisen as adaptations to different pollinators. Some Passiflora species belonging to the subgenus Decaloba sect. Xerogona, show touch-sensitive motile androgynophores. We tested the role of auxin polar transport in the modulation of the androgynophor

14. Genetic potential of common bean parents for plant architecture improvement
In common bean (Phaseolus vulgaris L.) breeding, plant selection that associate erect plant architecture, high yield, and grains with good commercial acceptance has been the choice of breeders. Thus, this study aimed to evaluate potential parents, to obtain promising segregating populations that associate high yield, erect plant architecture and carioca grai

15. SECAGEM, ARMAZENAMENTO E CONTROLE GENÉTICO DE CARACTERES AGRONÔMICOS E QUÍMICOS DE MANJERICÃO (OCIMUM BASILICUM L.). / DRYING, STORAGE AND GENETIC CONTROL OF AGRONOMIC AND CHEMICAL CHARACTERS OF BASIL (OCIMUM BASILICUM L.).
The aim of this work was to evaluate the influence of drying of leaves, the storage time of the essential oil and to study the inheritance of agronomic and chemical characters of basil (Ocimum basilicum L.). Three assays were carried out, where the effect of drying time of leaves, the influence of storage in different environments and the study of inheritanc

16. Performance and carcass traits in the diallel crossing of pacu and tambaqui
With the purpose of evaluating the changes and the degree of heterosis on performance and carcass traits of fish from the diallel crossing between Pacu and Tambaqui, four genetic groups were generated through hormonal induction: pacu, tambaqui, tambacu and paqui. For 196 days, 400 juveniles of each genetic group were stocked in a pond divided into four parts

17. Caracterização molecular de acessos de Ocimum basilicum L. por meio de marcadores ISSR
O estudo das relações genéticas é um pré-requisito para atividades em reprodução de plantas assim como para conservação de recursos genéticos. Neste trabalho a diversidade genética entre 50 acessos de Manejericão Iraniano (Ocimum basilicum L.) foram determinadas usando marcadores de Seqüência Simples Repetida Interna (ISSR). Trinta e oito alelo

18. Epistasia para a produção de grãos e caracteres da planta em milho / Epistasis for yield and plant traits in maize
It is known that epistasis may have important effects in the populations dynamics and in the evolutionary process of the species, and that it is involved in manifestation of important biological phenomena, such as overdominance, inbreeding depression and heterosis. However, epistasis is considered one of the more complex aspects of quantitative genetics sinc

19. Voluntary intake of dry matter and performance of Nellore cows and their Nellore and crossbred Simental × Nellore calves
This study aimed to investigate the influence of calf genetic group on the performance of Nellore lactating cows. The variables studied included milk ingestion, pasture intake, calf weight gain and cow body weight. A total of 13 Nellore calves and 8 crossbred Simental × Nellore calves were used, all born from Nellore mothers. During the experimental period

20. Combining ability of summer-squash lines with different degrees of parthenocarpy and PRSV-W resistance
The aim was to assess heterosis in a set of 16 summer-squash hybrids, and evaluate the combining capacity of the respective parental lines, which differed as to the degree of parthenocarpy and resistance to PRSV-W (Papaya Ringspot Virus-Watermelon strain). The hybrids were obtained using a partial diallel cross design (4 x 4). The lines of parental group I w

21. Heterosis performance in industrial and yield components of sweet corn.
Heterosis and its components were evaluated in a diallel crossing system of sweet corn. In the 38 treatments, eigth parents, 28 hybrids and two controls were used, arranged in a randomized block design with three replications.The diallel analysis followed the methodology of Gardner and Eberhart (1966). The following traits were evaluated: male and female flo

22. Heterosis in crosses among white grain maize populations with high quality protein.
The objective of this work was to investigate heterosis and its components in 16 white grain maize populations presenting high quality protein. These populations were divided according to grain type in order to establish different heterosis groups. The crosses were carried out according to a partial diallel cross design among flint and dent populations. Seve

24. Analise dialética e heterose de populações de milho-pipoca.
A diallel set of crosses among nine popcorn (Zea mays) cultivars, UNB-2, RS-20, UEM-J1, UEM-M2, CMS 42, CMS 43, Vicosa, Beija-flor and advanced generation of hybrid three-way Zelia, and their hybrid combinations was carried out to obtain heritability and heterosis estimates. The cultivars and F1s were evaluated in two crop years (1998/99 and 1999/2000) with
