Estudio del cambio climático y sus implicaciones en el cultivo del manzano en Asturias

Abstract

The rises in temperature have caused an advance in the blossoming period of Asturian apple varieties, mainly due to an increase in the heat units accumulated in spring. In the past three decades, the theoretical blossoming period has been brought forward by an average of 15 days. The combined effect of the rise in temperatures and the decline of rainfall poses a high risk of water deficiency to apple trees and other fruit trees grown in Asturias. This shortfall occurred in the last five years in over 50% of the spring and summer and is most dangerous in the blossoming periods and the period immediately after these, which in recent years have been precisely the times in which an increase in temperatures and a decrease in rainfall have been registered in Asturias.
