Clove plants can be generatively propagated by seeds and vegetatively by grafting. However, the success of clove grafting is still low (<50%), presumably due to the high content of phenol in the stem which inhibits callus formation and causes connection failure. The aim of the study was to obtain the best ascorbic acid concentration to reduce phenol content in the clove stem. The study was conducted at the Ecophysiology Laboratory, ISMCRI from January to June 2019. The study was arranged in randomized block design, 9 treatments with 4 replications. The treatments were ascorbic acid concentrations : 0 ppm (control), 25 ppm, 50 ppm, 75 ppm, 100 ppm, 125 ppm, 150 ppm, 175 ppm, and 200 ppm. The parameters observed were percentage of grafting survival rate, plant height, leaves number, stem diameter, chlorophyll content. The results showed that ascorbic acid had significant effect on the percentage of grafting survival rate, shoot length and number of leaves on the 4 months old-grafted seedling. The highest percentage of grafting survival rate (75%) was obtained optimal concentration at 128.93 ppm ascorbic acid treatment while the lowest was control (47.50%).
