'Pedro Sato' guava tree phenological characterization in different pruning times

Although the guava tree cultivation in the area of Lavras, MG, has had great importance, there is not a frequent offer during the year, concentrating the production in an only period. The practice of staggered prunings is fundamental to aid the producer to pick fruits in practically every month of the year. Seeking that stagger, it was aimed the 'Pedro Sato' guava tree phenological characterization in four pruning times (September and December of 2003, March and June of 2004). Ten four-year-old plants were used for each pruning time in randomized block design, where, in each plant, twelve branches were marked and the data were evaluated weekly on the phenological stages. It was possible to establish the indication of the different phenophases of the culture with the measuring, being the duration between the pruning and the beginning sprout from 30,8 to 39,2 days; between the pruning and the flowering from 68,6 to 133 days; between the opening of the flower (complete flowering) and the fruit ripeness from 118,3 and 148,4 days; and the pruning to the crop cycle happened on an average of 214,2, 211,4, 247,8 and 237,3 days for the prunings carried out in September, December, March and June.
