Seeking a less toxic alternative to budburst management than hydrogen cyanamide, doses of the mineral-organic product Erger® were tested in combination with calcium nitrate (Ca(NO3)2). The experiment was conducted in Santana do Livramento, southern Brazil, during the 2013/14 and 2014/15 growth cycles, in a ?Merlot? vineyard conducted in a vertical trellis system, pruned in double Guyot, with SO4 rootstock. Treatments were: Control (unsprayed); 5.0% Ca(NO3)2; 2.5% Erger® + 5.0% Ca(NO3)2; 5.0% Erger® + 5.0% Ca(NO3)2; 7.5% Erger® + 5.0% Ca(NO3)2; 3.5% Dormex® (positive control). All Erger® treatments stimulated budbreak, increasing budburst from 68% (unsprayed and calcium nitrate means) to 83% (Erger® means) in the first cycle and from 85% to 96% in the second one, with no difference among doses. Plants treated with Dormex® had budburst similar to Erger® in the first cycle (85%), but budburst in the second cycle was only 72%, possibly due to burned buds. Therefore, Erger®, in concentrations of 2.5% or more with 5% calcium nitrate, may be a promising alternative to induce budburst in regions with restrictions in cold availability.Index terms: bud dormancy, hydrogen cyanamide, Erger®, Merlot, Vitis vinifera. Manejo alternativo da brotação em vinhedos da Campanha GaúchaResumo- Buscando uma alternativa menos tóxica que a cianamida hidrogenada para o manejo da brotação, doses do produto organo-mineral Erger® foram testadas em combinação com nitrato de cálcio (Ca(NO3)2). O experimento foi conduzido em Santana do Livramento, região Sul do Brasil, durante os ciclos 2013/14 e 2014/15, em um vinhedo ?Merlot?, conduzido em espaldeira, podado em Guyot duplo e enxertado sobre SO4. Os tratamentos testados foram: Controle (sem aplicação); 5,0% Ca(NO3)2; 2,5% Erger® + 5,0% Ca(NO3)2; 5,0% Erger® + 5,0% Ca(NO3)2; 7,5% Erger® + 5,0% Ca(NO3)2; 3,5% Dormex® (controle positivo). Todos os tratamentos com Erger® estimularam a quebra de dormência, aumentando a brotação de 68% (média dos controles sem aplicação e nitrato de cálcio) para 83% (média dos tratamentos com Erger®) no primeiro ciclo e de 85% para 96% no segundo, sem diferença entre as doses. Plantas tratadas com Dormex® tiveram brotação semelhante ao Erger® no primeiro ciclo (85%), mas a brotação no segundo ciclo foi de apenas 72%, possivelmente devido à queima de gemas. Portanto, Erger®, na concentração de 2,5% ou superior, combinado com 5% de nitrato de cálcio, pode ser uma alternativa promissora para induzir brotação em regiões com restrições na disponibilidade de frio.Termos para indexação: dormência de gemas, cianamida hidrogenada, Erger®, Merlot, Vitis vinifera.

Abstract Objective: To evaluate the effect of treatment with trichostatin-A (TSA) on the production of bovine embryos, expressing the gene of the green fluorescent protein (GFP) generated by SCNT. Materials: 164 oocytes were distributed in three treatments, NT-GFP: newly reconstructed zygotes with genetically modified cells and not subject to TSA. NT-Trico-GFP: newly reconstructed zygotes with genetically modified cells and subjected to TSA. PART: Zygotes generated by parthenogenetic activation, used as a control for the process of oocyte activation and culture of embryos. The rates of cleavage, blastocysts, and embryos that expressed GFP were assessed by contingency tables and chi-square tests. Results: The percentage of cleavage in the zygotes in the NT-GFP treatment was greater but did not vary significantly from the NT-Trico-GFP treatment. However, this last treatment had a higher percentage of blastocyst formation (p = 0.077). The percentage of blastocysts from cleaved zygotes, the produced embryos were significantly higher (p < 0.05) for the NT-Trico-GFP treatment than for the NT-GFP. In both treatments, all the blastocysts generated expressed the GFP protein. Conclusions:TSA improves the embryonic development of clones of genetically modified cattle that express GFP. |
