Cytokinins affect respiration, ethylene production, and chlorophyll retention of packaged broccoli florets.

Cultivar Citation florets were treated postharvest with either BA or trans-zeatin at either 10 or 50 p.p.m. before packaging in perforated polyethylene bags and storage at 16 deg C in darkness (simulating adverse retailing conditions). The most pronounced effects were observed with BA at 50 p.p.m. Compared with controls, respiration rate was reduced by 50% and ethylene production increased by 40% throughout the first 4 days of storage. Total chlorophyll content dropped by 40% throughout the first 4 days of storage. Total chlorophyll content dropped by 60% in controls, but was unchanged in cytokinin-treated florets, which had a 90% longer shelf life than controls. These effects depended on the amount of cytokinin applied and were of greater magnitude with BA than with zeatin.
