THE RESPIRATORY INTENSITY OF CHERIMOYA DURING REFRIGERATED STORAGE: A SPECIAL CASE OF CLIMACTERIC FRUIT?

J. Moreno, J.L. De la Plaza
The respiratory intensity (RI) at 9°C storage in normal air was found to be the recursive trigonometric function

RINA= ∂1 sinpsi + ∂2psi cospsi + K

The coordinate auxiliary function from harvest was t - 12/2.38 and t - 5/3 for cvs. "Campa" and "Fino de Jete" respectively. The RI in controlled atmosphere storage takes the form of a classical harmonic oscillator

RICA= A cosWt + B sinWt + C

By using complicated but accurate integration processes, the integral geometric mean values of RI functions in four experiments were - performed to clarify the true values of RI of cherimoya during the particular evolution of interrelations between ripening and respiration in NA and CA storage.

The mean respiratory intensities (mg CO2/kg/h) were 44.93 and 12.37 in normal atmosphere and 48.97 and 54.54 in controlled atmosphere (2)10, for cvs. "Campa" and "Fino de Jete" respectively, which means that RI is 3.6 times greater in "Campa" than in "Fino de Jete", both of them in normal air, while in controlled atmosphere (2)10, it is 11% greater in cv. "Fino de Jete" than in cv. "Campa".

The increase in respiratory intensity due to controlled atmosphere profoundly changes the dynamic aspect of climacteric curves.
