ABSTRACT: Effects of hydrogen cyanamide on budbreak and flowering in Actinidia deliciosa cv. Hayward grown in orchards of Galicia (NW Spain). In Spain, half of the kiwifruit (Actinidia deliciosa) production is obtained in the province of Pontevedra, where the cultivar Hayward is mainly cultivated. In the areas where most orchards are established, the climate is characterized by mild temperatures in winter and a low interannual thermal variability. The lack of winter chilling limits commercial kiwifruit production, yet it can be replaced through the application of hydrogen cyanamide. For two consecutive years, field assays were carried out to study the effects of hydrogen cyanamide on budbreak and flowering of kiwifruit in two commercial orchads (Piñeiro and Tui) in Pontevedra (NW Spain). The product was applied forty days before the expected time of budbreak, at a concentration of 6%. The application of hydrogen cyanamide enhanced budbreak respect to the control, replacing in a great extend the lack of chilling required by Hayward vines to break winter dormancy. The product also caused an advanced time and sinchronization of budbreak and flowering. Keywords:chilling hours, kiwifruit, NW Spain, winter dormancy |
