The aim of this paper was to evaluate the effect of storage temperature on the quality of red pitaya of pulp white, produced in Itajobi city, São Paulo state. The pitayas were stored at room temperature, (21-27 degrees C with 44-63% de UR), at 18 +/- 1 degrees C, with 86-92% RH), 13 +/- 1 degrees C, with 85-90% RH and at 8 +/- 1 degrees C, with 85-95% RH. The quality was monitored during storage time through the parameters: fresh weight loss titleble acidity; soluble solids contents; vitamin C, external appearance, pH and fruit firmness. Through the results obtained may be concluded that the temperature at 8 +/- 1 degrees C it was proportioned the small fresh weight loss; the acidity, soluble solids, pH and fruit firmness were influenced by the storage temperature and storage time, but the temperature at 8 +/- 1 degrees C it was that occasioned the small change theses parameters. In general, it can be concluded that the temperature at 8 +/- 1 degrees C it was the best to maintenance the quality of pitaya fruit.

In sprinkler irrigation is important to have a good uniformity of application so that the water in the root zone does not show areas with little available water while others have percolating beyond the plant roots, even though the soil allows a lateral redistribution of water. A usual way to obtain the uniformity of irrigation is by measures of dispersion. The aim of this work was to evaluate the uniformity of water stored in a sand soil before and after non uniformity depth irrigation applied from one sprinkler, as well the variation of storage in a 0-0,45 m layer soil using a neutron probe. The statistical design was completely randomized, and for the variable Christiansen uniformity coefficient modified (CUCHH) were 10 treatments (the irrigation depth, 8 intervals of readings storage, more the existing one before irrigation added to the irrigation depth). For the variable soil water, the treatments were the same, excepting the irrigation depth. Despite the low surface uniformity (16.3%), there was not significantly difference between the storage uniformity before, after irrigation and the potential, however there was from these to the surface uniformity. From de irrigation depth, 15.3 mm, only 6.1 mm remained in the layer from 0 to 0.45 m. There was not significantly difference between the water stored in the soil before and after irrigation within a period of up to 134 hours, being the increase in storage due to irrigation was just 11.7%.
