Summary. The spraying of apple trees in July with N ‐dimethylaminosuccinamic acid (2000 ppm) (B9) delays both the onset of the respiration climacteric and increased ethylene production in fruit picked near the time of normal commercial harvest by about 10 days. It also reduces the rate of respiration at the climacteric peak by approximately 20%. the rate of ethylene production of fruit from trees treated with B9 is much reduced and may be only 20% of that of fruit from untreated trees. the amount of ethylene produced is, however, still sufficient to initiate the enzyme processes associated with ripening. It is suggested that the action of B9 is to modify the balance of the various hormones which regulate the development and ripening of fruits.
