Sucrose yield and its components are compared from 6 to 27 weeks after anthesis in vegetative canes induced to flower artificially, and in flowered canes on which the side shoots were continually defoliated. The results confirm earlier reports that flowered canes had higher sucrose yield than vegetative canes early after anthesis, and that these differences gradually decreased. The difference in sucrose yield between the above two types of stalks was due primarily to the dry weight component and not to sucrose content. Flowered stalks on which side shoots were defoliated showed an increasing loss of dry weight from 13 to 27 weeks after anthesis and consequently yielded significantly less sucrose than normal flower stalks. The reduction of dry weight was due solely to the DM percent cane component as no difference in fresh weight was detected between the two types of flowered stalks. The reduction of dry weight in defoliated stalks was due to losses of both sucrose and fibre in the proportion of 2 to 1 maintaining sugar yield and sucrose content of flowered stalks. The physiological, agronomic and breeding implications of the results are discussed. | |
