Abstract
Single applications of ethephon (1,000 pm) were made at three treatment dates to 20-yr-old Coville highbush blueberry plants. Berry weight, titratable acid, soluble solids content and yield were recorded. Average weight per berry was not consistently different in treated berries than in untreated but in both years the second and third sprays decreased the mean berry weight faster than occurred in the controls or first spray. Total yield was only slightly affected by treatment, indicating that a yield reduction would not be expected through the use of ethephon. Ethephon increased the rate at which the soluble solids and titratable acid (as citric) reached the normal level for ripe fruit.
