Sugarcane ( Saccharum spp. hybrids) plants were exogenously supplied with, 0, 1.0, 1.5, and 2.0 mg gibberellic acid (GA 3 ) per stalk in single and multiple applications. Increases in stalk fresh weight, total stalk length, and lengths of individual internodes were primarily a function of the interval between applications. Applications produced additive growth responses at 15‐ and 30‐day intervals but not at 0‐ and 45‐day intervals.
