ABSTRACT: The objective of this research was to define irrigation scheduling for coffee trees in the brazilian Cerrado region to optimize yield and coffee grain quality. The experimental treatments were: a) irrigation all over the year (RH1), suplemental water application after blossoming induced by rain (RH4), stop water application, at the harvesting time from June 15 to end of August until leaf water potenti...
The effect of cryopreservation in IFN-tau, from bovine embryos produced in vitro was evaluated. Two treated groups (G1= fresh bovine embryos, n=59 and G2= freezed embryos, n=84) were used to study the effect of cryopreservation on IFN-tau secretion. After reaching the blastocyst phase, the embryos were kept on individual culture for additional period of 7 days. On days 3 and 7 after the beginning of embryos cul...

A continuous assay using internally quenched fluorescent peptides with the general sequence Abz-peptidyl-(Dnp)P-OH (Abz = ortho-aminobenzoic acid; Dnp = 2,4-dinitrophenyl) was optimized for the measurement of angiotensin I-converting enzyme (ACE) in human plasma and rat tissues. Abz-FRK(Dnp)P-OH, which was cleaved at the Arg-Lys bond by ACE, was used for the enzyme evaluation in human plasma. Enzymatic activity...
Soil characteristics and tree growth as affected by slash management were assessed after the first clearcutting of a Eucalyptus globulus coppice plantation. The field trial was installed in March 1993, after the clearcutting of trees at the end of the first rotation. Treatments were removal (R), incorporation into the soil (I) and maintenance on the soil surface (S) of slash and forest floor litter layer; in t...
Estudou-se o efeito da pré-maturação em fluido folicular bovino (FFb) sobre o potencial de desenvolvimento de ovócitos bovinos imaturos. Complexo cumulus- ovócitos (CCO) e FFb foram obtidos de ovários coletados em matadouro. O FFb foi inativado e os CCOs imaturos distribuídos em quatro tratamentos: (T1) 70% de FFb em Talp Hepes, (T2) 100% de FFb, (T3) 100% de Talp Hepes, e (T4) controle. Em T1, T2 e T3 os CCOs ...
O objetivo deste trabalho foi avaliar o efeito de diferentes concentrações de taurina no desenvolvimento de embriões bovinos fecundados in vitro em meio de cultivo com diferentes fontes de soro. No experimento 1, zigotos (n=440) fecundados in vitro foram distribuídos aleatoriamente nos tratamentos com 0, 3, 7 ou 14 mM de taurina em meio de cultivo acrescido de 10% de soro fetal bovino (SFB) e 3g/l de albumina s...
Changes in the carbon stocks under different soil water and nutrient conditions were studied in Eucalyptus globulus Labill. stands in a field experiment, at O ´ bidos (central Portugal). The treatments were irrigation plus a complete fertiliser solution to simulate ‘near optimal’ nutrition (IF), irrigation only (I), and fertilisers added to rain-fed plots (F). The control (C) received neither water nor fertilis...
