Respiratory Inhibition of Mature Detached Blueberry Fruit (Vaccinium angustifolium Ait.) by N6-Benzyladenine, Kinetin, and N- Dimethylaminosuccinamic Acid

N6-Benzyladenine and kinetin, two cytokinins, and N-dimethylaminosuccinamic acid (Alar), a growth retardant, at various concentrations were found to inhibit the postharvest respiratory rates of lowbush blueberry fruits after storage for 14, 21, and 28 days at 2 C. Alar had the most pronounced inhibitory effect of the three compounds tested. The greatest respiratory inhibition occurred after 14 days and diminished at the 21- and 28-day sampling dates.
