Influência da cianamida hidrogenada na brotação e produção da videira 'Niagara Rosada' na região oeste do Paraná Influence of hydrogenous cyanamide in the sprouting and production of 'Niagara Rosada' grapevine, in the west region of the State of Paraná

Revista Brasileira de Fruticultura, 2008
As videiras apresentam um período de dormência que requer certa quantidade de frio para retomar seu desenvolvimento na primavera. Apesar da eficiência da cianamida hidrogenada na indução e uniformização de brotações na videira, ainda faltam estudos ...

Advancing Endodormancy Release in Temperate Fruit Trees Using Agrochemical Treatments

Frontiers in Plant Science, 2022
Endodormancy in temperate fruit trees like Prunus is a protector state that allows the trees to survive in the adverse conditions of autumn and winter. During this process, plants accumulate chill hours.

Heterogeneous Visible‐Light Photocatalysis in Continuous‐Flow: A Synergistic Strategy for Challenging Trifluoromethylation of α, α‐Diaryl Allylic Alcohols via 1,2‐aryl Migration

Advanced Science, EarlyView.
A continuous‐flow photocatalytic strategy is presented for the efficient synthesis of β‐trifluoromethyl ketones under visible light. Using a recyclable solid photocatalyst and an inexpensive CF3 source, the method enables rapid reactions, easy scale‐up, and smooth integration into multistep flow synthesis of bioactive molecules.

W‐N‐C Tandem Catalytic Centers Mediating Efficient Charge Transfer for the Enhanced Radical‐Path U(VI) Photoreduction

Advanced Science, EarlyView.
This work constructed a tandem W−N−C center to simultaneously achieve the regulation of reaction pathways and optimization of charge separation efficiency. The Lewis‐acidic W6+ sites activated O2 to generate O2−$O_2^ - $, with enhanced charge separation via electronic modulation, steering U(VI) reduction down an efficient radical pathway.

Performance of ‘Maxi Gala’ apple trees as affected by budbreak promoters, in São Joaquim-SC

Revista Brasileira de Fruticultura, 2018
The application of rest breaking agents to compensate the lack of chilling is a common practice in apple orchards in Southern Brazil. However, its necessity in areas of greater chilling accumulation has been questioned over the years.

Nickel Foam Electrodes—A Versatile, Powerful, and Readily Available Tool in Electro‐Organic Synthesis

The Chemical Record, EarlyView.
Nickel foam—one material, two faces, and several versatile roles depending on electrolytic conditions. For more than 50 years, nickel foam electrodes have served in electrosynthesis as powerful and readily available electrode materials. Due to their inexpensive nature and easy handling, they have been widely employed.

Redox‐Active Guanidines

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

RESPONSE OF STRAWBERRY PLANTS TO HYDROGEN CYANAMIDE AND POTASSIUM NITRATE APPLICATIONS

Acta Horticulturae, 1998
Several chemical substances, including hydrogen cyanamide and potassium nitrate, have been used on different plants, such as deciduous fruit trees, to break their dormancy and consequently improve the earliness of the crop. In order to study the effects of hydrogen cyanamide and potassium nitrate on dormancy breaking of strawberry plants, four ...
