Ripening activity of C.P.41845, a Monsanto product with growth‐regulatory properties, was examined in immature sugarcane ( Saccharum officinarum L.) having divergent growth regimes produced by variable nitrate and gibberellic acid. Plants were propagated in quartz sand with controlled moisture and nutrient supplies. Significant ripening activity was attained with 0.30% C.P.41845 within NO 3 and GA regimes highly favorable to growth and sugar utilization rather than sugar accumulation. Growth restriction per se was not needed to produce sugar accumulation. Sucrose, water‐soluble protein, and acid‐invertase levels in immature storage tissue were more sensitive to C.P.41845 action than were growth parameters. Results were consistent with the theory that sugarcane's rapid growth phase can be extended to within a few weeks of harvest with reasonable assurance that ripening can still be accomplished by chemical means.
