This study has been conducted to investigate the treatment time and concentration of GA<sub>3</sub> solution dipping for labor saving in 'Campbell Early' grapevine. The rachis growth at harvest was reduced by GA<sub>3</sub> solution dipping before 5 days flowering, and increased significantly by GA<sub>3</sub> solution dipping treatment at full bloom and after 5 days full bloom. GA<sub>3</sub> 5, 10, 20 mg·L<sup>-1</sup> dipping treatment before 5 days flowering and GA<sub>3</sub> 20 mg·L<sup>-1</sup> treatment of full bloom and after 5 days full bloom showed a rachis twist phytotoxicity symptom. The optimum GA<sub>3</sub> concentrations for rachis growth promotion without phytotoxicity were 5 mg·L<sup>-1</sup> and 10 mg·L<sup>-1</sup>. The degree of compact berry, bloom, skin color, SSC and acidity at harvest by GA<sub>3</sub> solution dipping treatment time between concentration were not different from those of control. But the fruit berry weight was decreased by before 5 days flowering treatment when compared with control. There were no differences in full bloom and after 5 days full bloom treatment. The occurrence percent of berry cracking at before 5 days flowering and after 5 days full bloom treatment were significantly increased by GA<sub>3</sub> treatment. The bitter rot occurrence of berry at harvest was not affected by GA<sub>3</sub> treatment. Total rachis length of fruit cluster was increased by full bloom and 5 days after full bloom treatment. The length of rachis increased without reference to them position at full bloom and 5 days after bloom treatment. Accordingly, GA<sub>3</sub> 5 mg·L<sup>-1</sup> solution dipping treatment at full bloom and 5 days after full bloom were can be effectively for rachis growth promotion.
