Ethrel (ethephon of 2-chioroethyl phosphonic acid) lossened lime fruits. The fruits removal force (FRF) of lime fruits was lowered to about 0.9 Kg. The concentration of 600 ppm of ethephon lowered FRF 6 to 9 days after treatment with no defoliation and fruit damage. Rapid decline in chlorophyll content occured 6 to 9 days after application of ethephon. Generally ethephon had no significant effect on vitamin C and total acidity of lime juice.
