Abstract: O objetivo do presente trabalho foi verificar qual o meio de cultura e quais as condi es que deveriam ser utilizadas em testes de germina o in vitro do pólen de pitangueira (Eugenia uniflora), bem como verificar a possibilidade de armazenamento em freezer (-18°C). O pólen foi coletado de flores em estádio de bal o e logo após a antese, em duas popula es desta espécie, na Embrapa Clima Temperado, em Pelotas, Rio Grande do Sul. Os meios de cultura testados foram o padr o (testemunha) (10% de a úcar e 1% de ágar em água destilada) e este acrescido de duas concentra es de H3BO3 (0,65 mM e 1,3 mM).Foram testadas as temperaturas de incuba o de 20, 25 e 30oC. Cinco horas a 25°C, em meio de cultura básico, proporcionou as melhores médias de germina o in vitro. O boro n o influenciou a germina o média de pólen de pitangueira. O pólen apresentou grande perda de viabilidade após 105 dias de armazenamento em freezer. The objective of the present work was to check the best medium andconditions for in vitro germination of pollen of Surinam cherry (Eugenia uniflora). Possibility of storage in freezer was also studied. The pollen was collected from flowers at balloon stageand immediately after anthesis in two populations of this species at Embrapa Clima Temperado Research Center, Pelotas, of state Rio Grande do Sul , Brazil. The tested media were the standard (10% sugar, plus 1% agar dissolved in distilled water), and the addition of two H3BO3 concentrations (0.65 mM and 1.3 mM) to this medium. Incubationtemperatures of 20, 25 and 30oC were tested. The best germination percentage was achieved after five hours incubating at 25°C. Boron did not influence the pollen germination of Surinam cherry. The pollen lost viability after 105 days of storage in freezer.

Abstract: the use of biological reactor effluent in fertigation and use of dry swine waste as a component of the substrate, would lower the cost of production and prevent discarding residues in the environment. based on that, the objective of this research was to evaluate both yield and quality of pepper fruits, adopting the factorial scheme 4 x 3 in randomized blocks, with 4 substrates (s1, s2, s3 e s4) and 3 nutrient solutions: mineral nutrient solution (sn1), nutrient solution as based on biological reactor effluent boosted with mineral fertilizers (sn2) and nutrient solution based on biological reactor effluent (sn3). the different mixtures that yielded different substrate could be recommended for both fruit and quality production perspectives, except substrate 1 (s1), which revealed inferior quality of fruits. the use of sn1 permitted greater weight of the fruits, thickness of the pulp and productivity. partial substitution of fertilizers by biodigestor effluent of swine waste (sn2) was not sufficient to promote productivity equivalent to 100% mineral nutrient solution, however it reached mean index of productivity with standards of quality of fruits equivalent to the mineral solution (sn1). this supports the conclusion that the use of the biological reactor effluent would be an alternative in potential to reduce the cost of production of pepper crop and to prevent the discarding of this material, still rich in nutrients, into the environment.

Abstract: the authors present at the beginning, the evolution of the attack against t. infestans, main vector of chagas' disease in the state of s?o paulo (brazil). they stress that at first there was a decline in the density of these insects in the counties worked periodically. this decline in density was followed by the reduction of the infection rate, by t. cruzi and machado guerreiro positive reactions. when the conditions became suitable, pedreira de freitas' selective method was introduced, making possible the improvement of the spraying technique and capture as well as the amplification of the protected area. they consider that a control campaing of the domiciliary vectors of chagas' disease present different phases and they try to explain when and how, in some counties in the state of s?o paulo they reached the surveillance phase as preconized by emmanuel dias. a pilot area was established, where methods of work are being studied and people hired in the surveillance areas are being trained. finally, they show that t. sordida and p. megistus are not reacting satisfactorily to the present method of attack.
