2.1. Morphology of cultivated rice

 

  The cultivated rice plant is an annual grass. Rice is a semiaquatic plant. It can adapt to a wide range of ecological diversity, from rainfed-dryland to deep-water flooded conditions. The stems consist of round, hollow internodes connected by nodes. The leaf blades are rather flat and attached to the culm by leaf sheaths. At maturity, the rice plant has  main stem and several tillers. Each productive tiller bears a terminal flowering head or panicle. Plant height varies depending on varieties and environmental conditions, ranging 0.4 m to more than 5 m in some floating rice. There are two rice species in cultivated rices.  They are Oryza sativa  grown worldwide and Oryza glaberrima  grown in part of West Africa.
