POSSIBLE IMPACTS OF CLIMATIC CHANGE ON BLOOM SUGAR GANE IN THE CENTRAL REGION OF CUBA

Abstract

Increasing proofs that the global climate is changing exist, principally for the variations of temperature and no knowing to those changes that are produced the answers of the plants. The objective of the present work was to estimate the influence that would cause to itself on the flowering of sugar cane to increase the temperature at the heartland of Cuba. The variety used C86-12 itself for it (the half a flowering’s indicator), the one that drank in 26 points located in different representative areas of the region of study, to the one that determined to him his intensity of flowering and associated with data of the half a temperature of the month of September (variable that the flowering at the region limits) using two scenes (normal and I enlarge 2 Celsius ). The valors of flowering and half a temperature of the region of study were represented in maps, constructed using the program Surfe v 8, 0 with the method of little grate Kriging. As a result it was found that the bigger quantity of bloomed varieties is produced at the mountains and bordering areas, under the normal oscillation of temperature, but when this increases 2 Celsius, the optimal limits itself toward the higher areas, the ones that more are scarce at the survey area, therefore the zones where a flowering is not produced, increase which limits the use of this region for the improvement of the cultivation in Cuba if they produce 2 Celsius’s increases in the half a temperature of the month of September.
