| The following methods of maturity testing were evaluated: field and laboratory brix, glucose ratio, moisture content of internodes and spindle and brix ratios. Highest correlation coefficients were obtained between pol per cent cane and laboratory brix throughout the harvest season. Correlations between pol per cent cane and field brix were significant only for the early and middle part of the harvest season, and those between pol per cent cane and field brix ratios were not significant. The best methods of detecting maturity in a field appear to be: evolution of field and laboratory brix in time. Field sampling techniques were studied for these methods. In a three stage sampling, a field was divided into four blocks within which three sites were selected and at each site three readings of field and laboratory brix were recorded. Differences between blocks were generally not significant while two readings per site was found to be the optimum. The number of sites per block varied with variety, locality and character measured. The best index was found to be the evolution of field brix recorded at the top of the cane (5/6 height of stalk). Laboratory brix required fewer samples than field brix but had to be rejected on account of higher cost. | |
