| Abstract:
A three year project of rejuvenation (1987–1989) based on integrated management in native peach in the Guatemalan plateaus resulted in vigorous growth of leaves and branches, improved flowering, heavier and more uniform fruits and better plague control. The difference in solid soluble content was not consistently different against the control trees. The incidence of Coryneum fruit stains and Monilinia (coffee rot) was substantially reduced in the experimental trees. The harm resulting from hail was reduced in the experimental trees in four out of five crops, possibly due to the thinning of fruit and to the increase in foliage, but there wasn't a great difference in the incidence of gashes in the fruit. The flowering occurred approximately two weeks earlier in the pruned trees - under integrated management-which resulted in greater damage in the 1989 frosts. Given this observation it is recommended to delay the pruning until half or more of the flowers have blossomed. | |
