Abstract:
Cyanamide (H2CN2) solutions and calcium cyanamide (CaCN2) suspensions at 0.25-1.25 M caused a rapid bud opening when applied to dormant intact buds of grapevine (Vitis vinifera L.). The H2CN2 had a more potent effect than the CaCN2. It is suggested that CaCN2 undergoes a partial hydrolysis to hydrogen cyanamide and cyanamide ions which can be the active form and react as the H2CN2 products. H2CN2 and other treatments such as wounding, hot water, dinitro-ortho-cresol (DNOC) and thiourea, increased sprouting of grapevine cuttings. Apart from thiourea, all the treatments enhanced respiration. The involvement of dormancy in blocking respiration and its possible removal is discussed. © 1983.
