Abstract
Sugarcane ( Saccharum spp. hybrids) stalk length, fresh weight, dry weight, and sucrose content, normally reduced when plants are grown under reduced sunlight (250 Langleys/day) and cool temperatures (mean daily temperature 23 C), can be increased with foliar applications of gibberellic acid (GA 3 ). Maximum increases in lengths and fresh weights of seven Hawaiian commercial cultivars were a function of cultivar treated, the amount of GA 3 applied, the number of applications, and the interval between applications. Lowland cultivars produced the largest gains in response to the largest quantities of GA 3 ; highland cultivars produced smaller gains. The effects of two applications of 1.0 mg GA 3 per stalk depended on the interval between applications. Least growth gains occurred when the intervals were 0 and 45 days; greatest growth gains occurred when the interval between applications was 15 days. The effect of a 30‐day interval was nearly equal to the 15‐day interval, but the 30‐day interval did not result in as great a loss of stalks as occurred at the 15‐day interval. Three and four applications of 0.5 mg GA 3 per stalk at 15‐day intervals were less effective in increasing stalk length and fresh weight than were three and four applications of 0.5 mg GA 3 per stalk at 30‐day intervals. Greatest gains in fresh weight in response to 2.0 mg GA 3 per stalk were in response to the greatest number of applications, four, if they were at 30‐day intervals.
