Cambios físicos y bioquímicos durante el desarrollo y senescencia de frutos de rambután (Nephelium lappaceum L.)

the aim of this research was to characterize the physical and biochemical changes during growth, development and postharvest of rambutan fruits in outstanding selections from tuxtla chico, chiapas (ri-148, ri-115 and ri-104). after anthesis, chemical and physical parameters were evaluated in fruits; at harvest quality characteristics were evaluated at 22 ± 1 °c and 65 % rh. the results showed a sigmoidal pattern of growth. during development, fruits of the selections ri-148 and ri-115 had a fresh weight of 39.27 and 35.42 g and an aril content at harvest of 44.28 and 40.90 %, respectively, while those of the ri-104 were smaller (18.51 g) but with thicker pericarp, showing less susceptibility to oxidation. the number and length of spines does not seem to be the main factor related to fruit browning.
