Abstract

SOUZA, Manoel Euzébio de et al. Influence of the precipitations pluviometrics in physical-chemical attributes of the fruits of the guajava tree 'Paluma' in different stadiums of ripening. Rev. Bras. Frutic. [online]. 2010, vol.32, n.2, pp.637-646.  Epub June 18, 2010. ISSN 0100-2945.  https://doi.org/10.1590/S0100-29452010005000060.

The objective of this work was evaluate the influence of precipitations pluviometrics weekly accumulated in the characteristics physical and chemical of the fruits of the guajava tree 'Paluma', in different stadiums of ripening. They were analyzed the following attributes: weight fresh, equatorial and longitudinal diameters, firmness, pH, titratable acidity, soluble solids, vitamin C, sugars reductors and sugars reductors total in three stadiums of ripening defined by the color of the shell (dark green, light green and yellow green). Among the physical and chemical attributes, barely the firmness diminished with the increase of the levels of weekly precipitations for a same stadium of ripening and still, presented decreases between the stadiums of ripening. The physical and chemical attributes, with exception barely of the pH, decreased with the increase of the weekly precipitations accumulated and in bigger intensities for the biggest stadiums of ripening.

Keywords : Psidium guajava; acidity; soluble solids; rainfall.
