WERLE, Tatiana et al. Influence of hydrogenous cyanamide in the sprouting and production of 'Niagara Rosada' grapevine, in the west region of the State of Paraná. Rev. Bras. Frutic. [online]. 2008, vol.30, n.1, pp.20-24. ISSN 0100-2945.

The vines present a dormant period which requires a chilling time to retake their development in the spring. Despite the hydrogen cyanamide efficiency in the vine sprouting, specific studies to determine the best dosage are still lacking, for it varies according to the region and application time. So, this study is justified in the west region of the State of Paraná. This experiment established six treatments of hydrogen cyanamide dosages (H2CN2): 0, 10, 20, 30, 40 and 50 mL L-1. The application was performed in August 16, 2005, by brushing the dormant buds. The application of hydrogen cyanamide provided a larger sprouting of the 'Niagara Rosada', providing an advance of nearly 14 days in relation to the control.The largest sprouting percentage was obtained with the treatment of 2 mL L-1. For the variables concerning to quality and productivity, there were no statistic differences among the treatments.
