Abstract:

This paper reviewed the phasic development of the rice plant and described in detail the developmental courses of root, shoot and leaf. These studies were based on the morphological and anatomical viewpoints. Recent advancement in genetics and molecular biology was integrated into the substages of each rice vegetable organ. Many mutants were found in the rice and this made us categorized the developmental processes more accurately. This work made the architecture and the developmental stages of rice plant cleared from the molecular aspect and also provided a theoretical foundation for various rice varieties with higher yield potential and greater yield stability.
