Flowering in two clones of Saccharum spontaneum L. is controlled by photoperiod. The earliest stages of development, 'induction' and 'initiation of the inflorescence axis primordium' (IAP) were optimally promoted under intermediate days of 12 h 30 min., while the subsequent stage 'initiation of inflorescence branch primordia' (IBP) was inhibited by days longer than 13 h. The following stage 'initiation of spikelet primordia' (ISP) showed a quantitatively intermediate response with an optimum photoperiod of 9 h to 11 h. The elongation of the differentiated inflorescence was found to be only slightly sensitive to photoperiods at stages following induction resulted in the IAP and IBP stages, reversion to the vegetative condition commonly occurred. | |
