Abstract

Flowering in sugarcane (Saccharum officinarum L.) is influenced by a number of plant and environmental factors. During the transition from the vegetative to reproductive apex, a number of physiological and biochemical changes occur as in other plants. The RNA content in the shoot apices of nine sugarcane varieties in relation to flowering was studied. The RNA content in the shoot apices of profuse flowering varieties increased at induction over that of the pre-induction stage. The magnitude of increase in the RNA content varied significantly among the varieties. The RNA content at the pre-inductive and the inductive period was positively and significantly associated with flowering.
