The deterioration and respiratory rate of carrot sections were measured to determine the effect of the ratio of vertical-or transverse-cut surface of sections. The small sections were more perishable than the large ones, the deterioration rate of sections of xylem was faster than that of phloem, and the sections having a high ratio of vertical area to the transverse decayed more rapidly than the low ones. The respiratory rate, O2 uptake and CO2 production, of phloem was lower than that of xylem, and the rise in respiratory rate of the sections having a high ratio of vertical area to the transverse was faster than that of low ones after decay. The difference of tissue or ratio of vertical or transverse area affected the respiratory rate and induced a difference in deterioration rate.
