13. Destino do nitrogênio (15N) do fertilizante em uma cultura de café / The fate of fertilizer nitrogen (15N) in a coffee crop
The coffee is one of the most important agribusiness products of Brazil and, although its management practices are already well defined, several cropping aspects still need a deeper understanding. Among these the nutrition of the coffee plant in respect to nitrogen is one of the main subjects needing more clarification. To contribute to this aspect, several

14. DeterminaÃÃo e remoÃÃo de erros em mapas de colheita de milho
The automation of the the monitorated harvest ends introducing systematic errors to the process, for this reason, a methodology of filtering of data became necessary for obtaining confident maps and it treats about the mean error factor, which is the delay time. The delay time is that spent between the cutting of the plant by the platformâs bar and the pass

15. Manejo florestal : impactos ecologicos de diferentes niveis de remoção e os impactos de sua sustentabilidade
The objective ofthis study was to evaluate an experiment offorest management established in 1980 at the Reserva Natural da Vale do Rio Doce, and monitored during a period of 20 years. The forest was exploited according to various levels of basal area remotion, totaling 9 treatments, including the control, in which no interference was made and the clearcut, w

16. Ethylene Production and Respiratory Behavior of the rin Tomato Mutant 1
Little or no change in ethylene or CO2 production occurred in rin tomato mutant fruits monitored for up to 120 days after harvest. Of the abnormally ripening tomatoes investigated, including “Never ripe” (Nr Y a h, Nr c l2 r), “Evergreen” (gf r) and “Green Flesh” (gf), only rin did not show a typical climacteric and ethylene rise.

17. Interaction of Vesicular-Arbuscular Mycorrhizal Fungi with Erosion in an Oxisol †
The development of vesicular-arbuscular mycorrhizal (VAM) symbiosis was monitored in Leucaena leucocephala grown in an Oxisol subjected to incremental simulated erosion. The density of VAM infective propagules in the soil diminished as the level of simulated erosion (removal of surface soil) was increased from 0 to 50 cm. The level of infection on L. leucoce

18. Population Dynamics of Sugar Beets, Rhizoctonia solani, and Laetisaria arvalis: Responses of a Host, Plant Pathogen, and Hyperparasite to Perturbation in the Field †
Rhizoctonia solani causes crown rot of sugar beets, a severe disease that has destroyed up to 60% of the plants in a test field in western Nebraska. Laetisaria arvalis, a natural hyperparasite of Rhizoctonia spp., was isolated from fields in western Nebraska. To test for the potential for biological control of R. solani, in November 1980 (following harvest)

19. Differentiation of selected Enterobacteriaceae by pyrolysis-gas-liquid chromatography.
Pyrolysis-gas-liquid chromatography was used to differentiate selected species of Enterobacteriaceae. Individual cultures of Salmonella typhi, Hafnia alvei, and Proteus vulgaris, and 12 strains of Yersinia enterocolitica were grown in nutrient broth. After harvest and lyophilization, the bacterial samples were pyrolyzed at 900 degrees C, and their volatile f

20. Nucleic acid spot hybridization: rapid quantitative screening of lymphoid cell lines for Epstein-Barr viral DNA.
A simple nucleic acid hybridization method to screen numerous samples of eukaryotic cells rapidly for their Epstein-Barr virus (EBV) DNA content is described. Whole cells are spotted on nitrocellulose filters and their DNA is denatured and fixed to the filter. The resultant DNA spots are hybridized to nick-translated EBV DNA and the extent of hybridization i

21. Starvation Improves Survival of Bacteria Introduced into Activated Sludge
A phenol-degrading bacterium, Ralstonia eutropha E2, was grown in Luria-Bertani (LB) medium or in an inorganic medium (called MP) supplemented with phenol and harvested at the late-exponential-growth phase. Phenol-acclimated activated sludge was inoculated with the E2 cells immediately after harvest or after starvation in MP for 2 or 7 days. The densities of

22. Mycotoxigenic Fusarium and Deoxynivalenol Production Repress Chitinase Gene Expression in the Biocontrol Agent Trichoderma atroviride P1
Mycotoxin contamination associated with head blight of wheat and other grains caused by Fusarium culmorum and F. graminearum is a chronic threat to crop, human, and animal health throughout the world. One of the most important toxins in terms of human exposure is deoxynivalenol (DON) (formerly called vomitoxin), an inhibitor of protein synthesis with a broad
