Ethylene production from dgt and wild-type tomato fruits during development. Fruits were harvested at the following stages: immature green (IG), mature green (MG), breaker (B), orange (O), red ripe (R), and full ripe (FR). Values are expressed in nanoliters per gram per hour (±se of the mean, n = 4–12 fruits). Fruits were obtained from the growth chamber experiment.
