Morpho-Taxonomic Distinction between Oryza rufipogon and Oryza sativa (Poaceae) at Seedling Stage

Abstract

Present study aimed to identify and differentiate between two important taxa Oryza rufipogon and O. sativa of the family Poaceae on the basis of their seedling morphology. Seedlings of the reported taxa can be differentiated from each other by comparing some morphological attributes such as Auricle, Caryopsis, Coleoptile, Collet, Epicotyl, First  internode, Hypocotyl, Leaf blade, Leaf sheath, Lemma, Ligule and Transitional node roots recorded during study. Comprehensive seedling morphology, Key and sketches have been provided in support of the observation.
