A review of evolution of oviposition guilds in the Bruchidae (Coleoptera) Rev. Bras. entomol.
Dan Johnson,Clarence; Romero,Jesús.
Three guilds of bruchid beetles oviposit on seeds at different times and in different ways, i. e., in these guilds some species only oviposit on fruits while on the plant (Guild A), other species only oviposit on seeds exposed in fruits while still on the plant (Guild B) and some only oviposit on seeds once they are exposed on the substrate (Guild C). It has been established that one plant species may be oviposited upon by all three guilds, some only by two guilds and some by only one guild. Before and after the inception of this concept many papers have been published that seem to establish that early oviposition behavior of bruchids was probably onto fruits where they burrowed through the fruit wall and fed on seeds (Guild A). Then, as evolution of the...

Accelerated aging and seedling field emergence in soybean Scientia Agricola
Torres,Reynaldo Melo; Vieira,Roberval Daiton; Panobianco,Maristela.
Information regarding the relationship between laboratory seed vigor testing and seedling field emergence is very important to estimate seed performance after sowing and help producers adopt the best procedures to improve stand establishment. The objective of the present study was to relate accelerated aging (AA) test results to soybean [Glycine max (L.) Merrill] seedling field emergence results based on data obtained over three agricultural years. The following evaluations were made: seed water content, standard germination, accelerated aging, electrical conductivity, and seedling field emergence. There was a close association between planting environmental conditions, seed physiological quality and seedling field emergence. The most accurate predictions...

ADVANCES IN GUAVA PROPAGATION Rev. Bras. Frutic.
PEREIRA,FERNANDO MENDES PEREIRA; USMAN,MUHAMMAD; MAYER,NEWTON ALEX; NACHTIGAL,JAIR COSTA; MAPHANGA,OSCAR RANNY MBONGENI; WILLEMSE,SALOMIE.
ABSTRACT Guava (Psidium guajava L.) can be propagated by seed, layering, air layering, grafting (budding or grafting), cuttings (root or shoot) or tissue culture. Propagation by seed is used for rootstock production and for raising populations for screening at early phases in the breeding programs. Vegetative propagation methods are used to clone selected genotypes from these programs and commercial orchards because it perpetuates all characteristics of each cultivar. This review addresses different methods that can be used to propagate guava, the methods commercially adopted and the progress obtained in recent years. There are several propagation technologies available, however, the adoption levels are rather different between producing countries. Needs...

ADVANCES IN PEACH, NECTARINE AND PLUM PROPAGATION Rev. Bras. Frutic.
MAYER,NEWTON ALEX; BIANCHI,VALMOR JOÃO; FELDBERG,NELSON PIRES; MORINI,STEFANO.
ABSTRACT Nursery trees of stone fruits (Prunus spp.) are traditionally produced by union of two distinct genotypes - the rootstock and the scion - which, by grafting, form a composite plant that will be maintained throughout of all plant life. In Brazil, the rootstocks are predominantly seed propagated and therefore usually results in heterogeneous trees for vigor and edaphic adaptation. However, with advances in rootstock breeding programs that released cultivars and certification in several countries (notably in Europe), the system will come gradually evolving for vegetative propagation (cuttings and tissue culture) and use of seeds of selected rootstocks with specific characteristics and potted nursery trees production. For scion cultivar propagation,...

Advances in the propagation of Brazilian Cherry tree Rev. Bras. Frutic.
Silva,José Antonio Alberto da; Teixeira,Gustavo Henrique de Almeida; Citadin,Idemir; Wagner Júnior,Américo; Danner,Moeses Andrigo; Martins,Antonio Baldo Geraldo.
Abstratct Brazilian Cherry tree is a native fruit tree belonging to the Myrtaceae family, with ample adaptation to the different edaphoclimatic conditions of Brazil, which makes this fruit widely known. However, there are still few commercial orchards, which may soon be reversed, since studies have shown the benefits of the consumption of this fruit for human health, as well as the potentialities for industrial processing. Thus, Brazilian Cherry tree will no longer be a backyard plant and will be grown in commercial orchards, which demands the production of seedlings with genetic quality. Sexual propagation with the use of seeds should be replaced by asexual propagation by means of cutting, grafting, spreading and tissue culture. The grafting method has...

Allelopathic evidence in exotic guava (Psidium guajava L.) BABT
Chapla,Tatiani Elisa; Campos,João Batista.
The allelopathic activity of the leaf aqueous extract of guava (Psidium guajava L.) on seed germination and root growth in lettuce (Lactuca sativa L.) was studied in an experiment consisting of four replicates with 10 seeds each and extract concentrations of 5, 10, and 20%. Guava allelopathic activity occurred during the germination and growth of lettuce roots at 20% extract concentration, as shown by ANOVA. This result suggested the allelopathic potential of the species. Therefore, the success of P. guajava in invading environments could be partially due to allelopathy. Further studies using other plant parts and field experiments should be conducted.

ARAÚJO, S. N.; MATRANGOLO, W. J. R.; MIRANDA, G. A. de; NETTO, D. A. M.; SILVA, I. H. S. da.
A Cratília é leguminosa arbustiva nativa do cerrado, tolerante à seca e a solos ácidos e tem potencial para adubação verde e forrageamento. Por essas características, pode ser utilizada pelo agricultor familiar. Objetivou-se verificar a viabilidade das sementes para posterior produção de mudas e doação a produtores familiares. As vagens foram coletadas de 126 plantas da EPAMIG. Após secagem em estufa, as vagens foram pesadas e debulhadas manualmente, resultando em 14,8 kg de sementes. Essas foram armazenadas em sacos de papel em câmara fria e seca. Foram realizadas as análises de pureza física, peso de mil sementes, determinação do grau de umidade e dois testes de germinação, sendo um inicial e outro após dois meses de armazenamento. Os testes seguiram as...

Anting behavior by the White-bearded Manakin (Manacus manacus, Pipridae): an example of functional interaction in a frugivorous lekking bird Biota Neotropica
Cestari,César.
Behavioral studies of birds have reported several functions for active anting. Maintenance of plumage and prevention from ectoparasites are some examples. In this context, anting by males may be of particular importance in a classical lek mating system, where male-male competition is common and individuals with higher fitness may be more successful at attracting of females. In the present note, I describe the anting behavior of White-bearded Manakin (Manacus manacus) and I relate it to lek breeding and feeding (frugivory) habits of the species. Males used up to seven Solenopsis sp. ants. They rubbed each small ant from 4 to 31 times on undertail feathers until the ants were degraded; ants were not eaten. Males then searched for a new ant in the court....
