The information presented is based on the data and characteristics of IR64, a modern, high-yielding, semidwarf variety, but applies generally to other rice varieties. This reference guide will enable you to: recognize the 3 basic growth phases of the rice plant and the stages of development in each phase. identify the growth stages of a rice plant according to a 0-9 numerical scale. Each number in the scale corresponds to a specific growth stage. explain the specific physical changes in a growing rice plant.
